INTRODUCTION

Congratulations on your purchase of the Bryston SP3 preamplifier/processor. This product will provide you with the finest available signal control and DSP audio processing available. Like all Bryston products the SP3 has been carefully designed and engineered to deliver a lifetime of enjoyment. The SP3 offers both pre-amplifier and digital decoding functions, and it is very important that you thoroughly read this manual BEFORE you install and use the SP3.

• The Status LED located above the Standby button should be lit red a couple of seconds after the unit is plugged in. Press the Standby button & the red LED will extinguish & the alphanumeric display will come on, initially showing “Bryston Surround Processor 3”.

• Within a second or two the status screen will be displayed showing four lines: Source (input source signal), IN: (input format), OUT: (output signal format) and Volume: (in decibels).

UNPACKING

Your SP3 was carefully packed at the factory to protect against any damage in shipping and handling. Carefully examine the packing and the unit for any signs of external damage or impact and report those to your dealer or Bryston prior to using the unit. Bryston advises that you keep all packaging in the event that the unit may have to be returned for service.

ACCESSORIES

In the carton you should have found the following accessories in addition to the SP3: 1 Bryston SP3 Instruction Manual 1 IEC standard power cord 1 BR3 Infrared Remote Control unit with battery in-

stalled

SAFETY

It is important that you read and completely understand the

safety instructions and warning on page one of this manual before installing or connecting the SP3 to any electrical power source.

QUICK START

• Plug into an appropriate power source using an approved IEC-60320 power cord with a C13 plug on the equipment end. Check the Data Plate (a 1.5” x .625” sticker containing the electrical ratings for your unit) located on the rear panel near the power inlet to confirm that the unit you have is rated for the electric power supply in your region.

• Connect suitable inputs & outputs to the SP3. If you are connecting a DVD player to an SPDIF or TOSLINK input, connect it initially to SPDIF-1 or TOSLINK INPUT-1 (which are the default assignments; these assignments can be changed at any time in

Sources

). If you are connecting to an HDMI input, use HDMI-1 which is assigned to the DVD buttons on the front panel and the remote control. The video signals carried on the HDMI cable are looped through to the HDMI outputs.

System Menu  Digital

Before adjusting items in the menus described be-

low it should be noted that the factory default settings should be suitable for most typical surround setups. In short, the factory defaults for the most fundamental settings are:

• Speakers: 5.1 (Source Setup, Spkr Sz)

• Speaker Size: small (Source Setup)

• Subwoofer: On (Source Setup)

• Distance: 2 meters (System Setup)

• Speaker levels: 0 (Source Setup)

• Press the right arrow menu navigation button  and you

will be at the top of the main menu. When the cursor is pointing at SYSTEM SETUP and you press the right arrow button  again you will move into the System Setup menu.

However, if you press the

down arrow  first so that the cursor is pointing at SOURCE SETUP, then pressing the right arrow button will move you into the Source Setup menu.

• To back up, all the way to the startup screen if desired, just keep pressing the Left arrow button  .

For more information on the

menu system, see pg 12

Owner’s Manual Updates

The SP3 Owner’s Manual is regularly updated Check the Downloads Technical section of Bryston’s website at wwwbrystoncom for the latest revisions Note: the revision number follows the document number, separated by a dash, and can be found in the bottom left corner of the last page of this and other Bryston Owner’s Manuals

FRONT PANEL

A: ALPHA NUMERIC DISPLAY B: MENU NAVIGATION Buttons C: FUNCTION & OPERATION Buttons D: VOLUME CONTROL

A: ALPHA-NUMERIC DISPLAY

This is a dot matrix display that can display graphics

as well as 4 lines of alpha-numeric characters. The brightness of the display can be set in 4 steps from 25% to 100% using the DISPLAY button (see section “C” below). A default brightness level can also be set in the System Setup menu as can the automatic timeout period (from 30 to 600 seconds). When the timeout period expires the display will extinguish automatically. To reawaken the display press the currently illuminated Source Select button (section “G” below). Pressing any button or turning the rotary encoder (Volume control knob) will also wake up the display but will also effect a change (e.g. rotating the volume control clockwise will increase the volume, etc.).

B: MENU NAVIGATION BUTTONS This cluster of 4 buttons are used to navigate the

menus on the Alpha-numeric display. After the unit has powered up a status screen is displayed like that at the right. Press the right arrow button () to enter the main menu. Use the left arrow button () to step back up

through the menus. The up () and down () buttons are used to move up and down through the menu items. The rotary encoder (volume control) can be used to set most parameters, even on/off choices. The two Surround Mode buttons can also be used to choose from preset value options.

Up () and/or down () arrows may be displayed at

the right hand side of the display to indicate that more items are listed either above and/or below the current screen. Use the up () and () down buttons to go to these items.

■ DISPLAY Selects display brightness in four steps: 25%, 50%,

75% & 100%. To set an automatic timeout for the display to extinguish, set the options n the SYSTEM SETUP -> MISC. menu. Choosing DISP+LED TOUT instead of DISP TIMEOUT will apply the display timeout value to all front panel indicator LEDs as well as the dot-matrix display. Once a value for DISP+LED TOUT has been set the front panel DISPLAY button will also facilitate extinguishing all LEDs plus the dotmatrix display.

■ SURROUND MODE

These Left & right Surround Mode ( & ) buttons

allow for selection of up to 8 different surround modes including: PLIIx-Music, PLIIx-Movie , Neo-6 Music, Neo-6 Cinema, PLIIx-Natural, Pro Logic, Club , Party, Stereo-7. These modes derive surround modes from stereo (2 channel) analog DVD inputs. If a 5.1 surround signal is selected as the input, some surround modes can derive the 7.1 format Back channels from the left and right surround channels. These buttons can also be used to select values in the menu system.

See Appendix for more information about the various

surround modes.

■ DIGITA L

Sets the source select button (G) to select from 1 of the

4 SPDIF inputs (RCA [phono] jacks, one of two AES

■ HDMI

Sets the source select buttons (G) to select one of 8

HDMI inputs. The audio content will be processed through the SP3’s DSP but the video content will simply be passed through to the two (parallel) HDMI outputs.

■ 2 CHANNEL BYPASS

Selects Left and right (or the front left and right) inputs

from whatever analog source is currently selected. If the DIGITAL mode is active (i.e. if the LED above the DIGITAL button is ON) then this becomes a digital

Page 6

down-mix into a stereo Left and Right output.

■

STEREO & STEREO DOWN-MIX MODE

If this button is selected and the supplied bitstream is

more than 2 channels, the decoder will automatically implement a stereo down-mix. Otherwise, analog or digital two channel signals are passed as conventional stereo.

NOTE: Down-mix is a software based auto-

matic mixing function available within the SP3. This process exists because whenever the number of active decoder outputs or loudspeakers selected in setup is less than the number of channels in the Digital program, some channel combining will be necessary to present the program on the available number of channels/loudspeakers.

As a part of any program’s production, its pro-

ducers can set and adjust the type and ratios allowed for down-mixing somewhat to ensure optimum results without compromising the

full Multichannel balance. This is accomplished by including specific data within the Dolby Digital bitstream which represents different mixing coefficients for the centre and surround channel signals.

These will be detected by the SP3 and used to

produce the down-mix if this mode is selected.

D: VOLUME CONTROL / ROTARY ENCODER

Continuous rotary optical encoder for determining vol-

ume level as well as an input for most variable settings and other selections within both the System and Source menus.

Note that when the volume level is being adjusted the

display changes to large numerals showing the level in decibels

E: HEADPHONE JACK

Stereo (3 conductor) 1/4” headphone jack. In 2 Channel

Bypass mode the Left and Right analog inputs appear, amplified, at the headphone jack. When other sources are selected a stereo down-mix is used.

SP3 PREAMP / PROCESSOR

F: MAIN / ZONE SELECT

The SP3 can send a different stereo audio source

signal to its ZONE outputs (Zone 2 Out) than to its main outputs (Single Ended Outputs or Balanced Outputs). Pressing the MAIN button allows selection of the signal that will go to the Single Ended Outputs and Balanced Outputs using the source select buttons (item “G”) while pressing ZONE allows the same source select buttons to set the signals that will be sent to the Zone 2 Out outputs)

G: SOURCE (INPUT) SELECT BUTTONS

Ten buttons for selecting audio input source signals (see

”F” above). When HDMI is selected (LED above HDMI button is ON) the first 8 source select buttons (DVD, CBL/SAT, TUNER, CD, DVR, TAPE, BAL-1, BAL-2) represent HDMI inputs 1 through 8 respectively. When MAIN is selected, source signal selected will appear at the MAIN outputs. When ZONE is selected, the source signal selected will appear at the ZONE 2 OUT outputs

H: STANDBY BUTTON

Places the unit in standby mode. Status indicator LED is

normally off when unit is operating. It turns red when unit is placed in standby mode. When uploading new software it may blink off and on in different colours. The specifics of theses different colour states is significant only to engineering and service personel.

Power consumption in Standby mode is <1 Watt.

The SP3 Remote Control can operate all front panel operations in addition to having a MUTE button to for quickly silencing the output of the SP3. Several other functions are accessible by sending 3 digit numeric codes to the SP3. To send codes to the SP3: 1: Press and hold the CODE button until the status LED on the remote

(located between the CODE and POWER buttons) flashes a couple of times & then stays lit steadily red; then release

2: Within a few seconds, while the status LED remains steadily lit, enter

the desired 3 digit numeric code (see the table below for valid codes). Refer to the BR3 illustration below for the location of the number keys on the remote.

3: When a valid code has been entered the LED will flash twice to con-

Dolby Pro Logic

firm that the code has been accepted.

Certain features in the remote control itself can also be programmed by entering codes as described above. The only differece is that these codes affect only the BR3 remote control itself and are not sent to the SP3. These codes are as follows: 792: Toggle motion sensor on/off (backlight control) 797: Toggle backlight on/off

BACKLIGHT OPERATION

When enabled, the backlight will only come on when the ambient light falls below a predetermined level If the motion detector (code 792) is disabled then the backlight will come on only when a button is pressed AND the ambient light level is low enough If both the backlight and the motion detector are both enabled the backlight will come on when the unit experiences movement and/or when any of the buttons are pressed AND the ambient light is low enough

NOTES

SYSTEM SETUP MENU:

. AUTOSAVE: When enabled (ON) settings are saved whenever you

backup through the menu by pressing the left arrow button (). If Autosave is OFF settings will NOT be saved.

SPEAKER DISTANCES: Units for speaker distances are set in the SYSTEM > MISC. menu. Speaker distances are measured as radii from the listeners position. See the illustration SUGGESTED SURROUND SPEAKER PLACEMENT on page 18.

DIGITAL SOURCES: Each of the Source Select buttons, on the front panel and on the remote control (DVD, CBL/SAT, TUNER, etc) can be programmed to select a digital input from one of the four coaxial SPDIF inputs or one of the 3 TOSLINK optical inputs.

MISCELLANEOUS: HEADPHONES: The signal level at the headphone jack can be adjusted

from -12 dB to +6 dB to match headphone level more closely to the speaker listening levels

PRESET VOLUME: The volume level at power-up can be pre-set to any-

where between -60 and +30dB

AUX Outputs: The L-AUX and R -AU X auxilliary output jacks (XLR

-male balanced) can be set, by this menu item, to be either another Left/Right stereo pair of outputs or another sub-woofer and another centre channel surround outputs.

As a stereo pair, the signal is analog if the SP3 is in 2

CHANNEL BYPASS mode or otherwise it is a digital downmix from multi-channel inputs.

As set to provide another sub-woofer and centre chan-

nel output, the signals for these channels are the same as the signal that would be present on the main Subwoofer and Centre channel outputs connectors. These simply provide a convenient way of using two centre channel speakers and/or two sub-woofer speakers.

TRIGGER DELAY: The SP3 can be set to produce a 12Vdc trigger signals

on any of the three Trigger Output jacks. See item 14 on page 9 (TRIGGER INPUTS & OUTPUTS). The tip of the two conductor (3mm) phone jack is positive and the sleeve is ground (0v).

TESTS (Pink Noise): Will put a burst of pink noise, sequentially, on all speakers while displaying which output the test signal is being sent to. This is intended to help you verify that the connections and speaker levels are correct. Within the System Setup  Test menu, move the cursor to select PINK NOISE and press the right arrow button () to initiate the test (and the left arrow button () to stop it, if desired). The auto-cycling will stop on its own once all outputs have been sent a pink noise burst. To operate the pink noise test manually from the front panel, press the right arrow button again each time you wish to advance through the outputs, sequentially putting bursts on one speaker after another. In this case the noise test switches to “manual” mode and each channel will play until the right or left arrow is pressed again. Pressing the left arrow button will exit the test sequence. To use the BR3 remote control to initiate the test press the TEST button on the remote . To change form AUTOCYCLE to MANUAL press the TEST button again To advance the channel from the remote press right arrow again; to exit press left arrow button. The volume control can be used to adjust the output levels during the test.

SOURCE SETUP MENU:

SPEAKER SIZE: Large speakers are assumed to be able to handle all frequencies down to at least 40 Hz. A speaker defined as SMALL has the low frequencies filtered out. The default crossover point for the low frequencies is 80 Hz but this can be changed in software (SOURCE SETUP > CROSSOVER) from 40 to 200 Hz. The speaker size menu also allows for turning the CENTRE, SURROUND & BACK speakers off by selecting NONE. Also, the BACK speaker setting allows for choosing from one

APPENDIX A SP3 SURROUND SOUND MODES

SP3 SURROUND MODES

Pressing the SURROUND left () and right ()arrow but- tons button will allow you to sequentially select one of the many available decoding modes for expand almost any 2 channel music source signals. The custom SP3 Surround Modes use a set of DSP algorithms to create a set of simulated surround sound signals from the original left and right 2 channel data.

CLUB: This Sound Field Mode is intended to simulate being fairly close, around 10 feet away, in a small intimate club setting with a moderate amount of reverberation that does not destroy clarity. The result is a bit colored for speech due to the small room size, but it is quite suitable for jazz groups, cabaret, small-venue rock ‘n roll, and a small disco venue where dance music is played. This mode can also be used for classical chamber music and solo instrumental music of most kinds.

NATURAL: PLII Natural mode enhances the basic stereo reproduction by using the inherent acoustics recorded within the source material. If the source material was surround encoded or recorded in an acoustically oriented manner (such as a lot of classical music and many live recordings) this mode can provide truly spectacular effects and an enhanced sense of the space in which the music was being performed.

a single limited frequency-range mono rear channel using ‘Steering Logic’, which drives amplifiers, to raise or lower the output volume of each channel based on the current dominant sound direction. In addition the surround channel is slightly delayed, so that any front channel sounds that leak into the surround channel arrive at the listener after the front channels, providing an illusion of greater separation.

PLII MUSIC: This mode can enhance normal stereo music recordings, offering a wider soundstage and enhanced spatial effects. This offers user control over:

PLII MOVIE: This is the preferred decoding method for watching movies with matrix surround encoding. The centre width and dimension variables are set and optimized for this application, and cannot be adjusted. No filters are present on the surround channels, and auto-balance is operational.

NEO:6 MUSIC: Neo:6 derives a centre channel from two-channel material. Neo:6 music mode to expands stereo non-matrix recordings into the five- or six-channel layout, in a way which does not diminish the subtlety and integrity of the original stereo recording. In music mode, the intent in the front channels is less one of steering and more one of stabilizing the front image by augmenting it with a centre channel, while preserving the original perspective of the stereo mix. Therefore the derived centre is never fully subtracted from the left and right channels.

PARTY: The Party (Seven-Channel Mono) Mode converts stereo input to a mono signal which is then distributed to the 7 satellite channels plus sub-woofer.

STEREO7: The Stereo7 (Seven-Channel Stereo) Mode converts stereo input to surround sound. The stereo signal is distributed to the 7 satellite channels plus sub-woofer, creating a giant stereo image in your listening space.

PRO LOGIC: Dolby Surround/Pro Logic is based on basic matrix technology. When a Dolby Surround soundtrack is created, four channels of sound are matrix-encoded into an ordinary stereo (two channel) sound track. The centre channel is encoded by placing it equally in the left and right channels; the rear channel is encoded using phase shift techniques. A Pro Logic decoder/processor “unfolds” the sound into the original 4.0 surround—left and right, centre, and

NEO:6 CINEMA: In cinema mode, for Left/Right film soundtracks, sounds steered to the centre are subtracted from the left and right channels. Neo 6 provides up to six full-band channels of matrix decoding from stereo matrix material. Users with 6.1 and 5.1 systems will derive six and five separate channels respectively, corresponding to the standard home-theater speaker layouts. (The “.1” subwoofer channel is generated by bass management in the preamp or receiver.)

(Please note that the apparent effect of the Surround Modes can be adjusted by altering the delay parameters and channel volume of the centre, surrounds and back channel(s), using the appropriate menus).

ves commands and send responses

SP3 recei to each command. It can optionally broadcast automatic responses to certain system events such as source switching by the front panel etc. (see AUFB). The format of the automatic responses is the same as the response to a serial command sent with the parameter bytes P1 P2 = "QS".

Command format are all ASCII strings with the carriage return ending:

# D1 D2 C1 C2 C3 C4 P1 P2 ... <CR>

# - command start character D1 - device category, 1 digit 1..f(SP3=1) D2 - RS485 device ID, 1 digit 0..f(dflt=0) (D2 can only be changed through the front panel menu!) Currently D1 D2 must be "10".(*) C1..C4 - command name (4 chars) P1,P2,.. - parameters n>=2 chars (variable) <CR> - end character (code 13 or '\r' in C/C++)

Example: #10MPWR01<CR>

NOTE: ANY CHARACTERS PRECEEDING # AND FOLLOWING THE <CR> WILL BE IGNORED BY SP3. DO NOT INSERT #, SPACES, <LF>, <TAB> OR OTHER NON-PRINTABLE CHARACTERS INSIDE THE COMMAND.

Response format is the same as commands, repeating the D,C and P bytes (P bytes may carry the actual status or ?? as error marker)

Example: #10MSRC00<CR>

NOTE: DO NOT ASSUME THAT THE NUMBER OF RESPONSE BYTES R1,R2.. IS ALWAYS FIXED. ALLOW UP TO 320 CHARS AND READ ALL UNTIL <CR> AT THE END.

SP3 – HDMI Notes (1)

DMI Handshaking

When SP3 selects HDMI input port as its audio signal source, it acts as an HDMI repeater, placed in between HDMI signal source (DVD player, BD player etc) and HDMI signal “sink” (TV screen, TV projector etc). Every class of the devices on the HDMI chain has to respond to the HDMI handshake procedure, initiated by the signal source, that is by a player. The handshake is initiated normally on power up, on disk reinsertions, or on other events. In order to make the initial handshake proceed optimally, the HDMI devices should preferably be powered up beginning with the “sink” (TV screen), then the repeater (SP3) then the player. That way the main signal source will be immediately able to poll (handshake) the rest of the HDMI chain which will already be powered up and ready to respond.

sing more than 1 HDMI sources (players)

If two HDMI sources are connected to SP3 HDMI inputs, then SP3 will select only one link at a time, leaving the other link “dead ended”. This may break the established handshake status between the player that is not currently active, and the TV screen resulting in a possible change of the player output signal format. This behaviour is strongly player-dependent and copy-protection dependent on the media being played. Some DVD or BD players maintain the last signal sample rate and format that was played previously to an interruption (or disconnect)

, some other players tend to immediately downgrade the output stream from multichannel audio to stereo or from encoded streams such as DTS or Dolby Digital to PCM. Some players may also downgrade the sample rate of audio and downgrade the video resolution.

This may cause various artefacts or somewhat unpredictable behaviour (loss of audio etc) when switching away from one HDMI source to another source and then back. If the drive switched the format while being disconnected and would not restore the previous one, then pressing HDMI button again to switch it off to analog

and then on again may

force the drive to re-handshake and restore the original.

If that does not restore the correct HDMI status then reinserting the disk or re-powering the player may be necessary.

As long as the disk is in.

HDMI button toggles between HDMI active and Analog mode, while the actual HDMI chain link from the source to the TV screen remains unbroken. As long as the main source selection remains unchanged. This feature allows passing the video signal through HDMI while using analog for audio. At the same time since the HDMI chain remains unbroken while toggling the HDMI active on/off , it allows the player to re-handshake with the TV screen re-establishing the original channel format.

APPENDIX D: HDMI NOTES continued

Selecting HDMI inputs on SP3

Normally, HDMI inputs are associated with the corresponding source selector buttons on the front panel, from left to right. DVD button is associated with HDMI input1, CBL/SAT button with HDMI 2, ... BAL-2 with HDMI 8. For each of the first 8 source selector buttons there are 3 alternative inputs sockets to chose from: DIGITAL or analog disabled and the new associated HDMI input to be automatically selected and enabled for video and audio pass-through on that input the new HDMI input is selected then the video is passed-though while audio is intercepted by the SP3. This behaviour can be modified in the firmware revision 2012.08 or later, with the introduction of HDMI INPUT STICKY option in MISCELLANEOUS menu remains selected and active even after switching to a different source, for as long as the new source selection does not select HDMI explicitly. It persists through power downs. It allows displaying video image from one source player, while playing audio from another.

The signal source determines the channel format. If the number of channels being played is not as expected, for example 2 instead of 5.1 or 7.1 then the SP3 and the player may have to re-handshake the communication protocol through HDMI in order to reset the proper status. Certain media (DVD, BD) revert to a 2 channel audio format during menus and then switch to multichannel when playing a selected contents. Some media contents may be originally recorded as 2 audio channels, in this case one can use the

surround synthesis

feature in the SP3 to re-create 5.1 or 7.1, for example select Dolby

Prologic IIx Movie etc .

A player (the HDMI "source") will communicate ("handshake") with the SP3 (the "repeater") and the TV screen (the HDMI "sink"), trying to set itself up to output the

Pressing DIGITAL button selects one of the following seven digital inputs: SPDIF1,2,3,4 or Toslink 1,2 or 3. The specific assignment determining which of the seven inputs is used, can be configured in the SYSTEM SETUP-->DIGITAL SOURCES submenu..

Analog inputs are selected when neither DIGITAL nor HDMI LED are lit. Analog input has two modes of operation: normal when the signal goes through A/D, DSP and D/A with all the surround processing available, and 2 channel bypass mode selected by 2 CH.BYPASS button, when the signal bypasses the digitization stage, while only going through analog the volume control stage.

Video passes through from one selected HDMI inputs 1 to 8 to both HDMI output sockets 1 and 2, operating in-parallel. It is possible to drive two TV screens simultaneously.

The screen is locked, to unlock it scroll down to the 3-rd MISC screen down from the top and press ZONE,DVD and TAPE buttons in a sequence in this order.

This is often referred to under the term “re-creation” mode that is creating the extra audio channels out of the stereo feed. Use surround left and right arrow keys to select among several surround modes. Those selections are not applicable when the original content is 7.1, and only a limited selection is applicable with the original 5.1 stream when 7.1 has to be synthesized out of the 5.1.

highest resolution (video) and the highest number of audio channels that the SP3 declares

as available, and the highest sample rate

that is available in the media being played, still supported by both the SP3 and a TV screen further down the HDMI device chain. This is determined by the maximum capability of the SP3 (Video up to 1080p, 3D, color depth 36, audio 7.1 channels up to 192kHz sample rate). In some cases very long HDMI cables (i.e 10m) become the limiting factor preventing establishment of the highest possible video mode. In such cases the source device will often negotiate a lower video or audio resolution format than the one that is possible over a shorter or a higher quality cable

Because the source-repeater-sink setup is capable of dynamically configuring itself over HDMI as a whole, it may result in very different behavior than if the same devices were connected using a different method, for example video through DVI and audio through SPDIF, Toslink or analog RCA.

For example, if a multi source is being played and the audio receiver (SP3) suddenly changes from multichannel speaker configuration, to 2 channels, which happens when the headphones are plugged into headphone jack on the SP3 or when STEREO button is pressed, then most players would automatically downmix the stream being played to stereo, on-the-fly.

With HDMI it is the player which typically downmixes the program format to stereo when headphones are plugged to SP3. Without HDMI the downmixing to stereo takes place in the SP3 rather than in the player.

PCM versus “bitstream”

Most DVD and Blue-ray players can be configured to output audio contents either as PCM (or “Linear PCM”) or as “bitstream”. The former option makes the player decode and covert the media format to an uncompressed PCM format which is the most compatible. The latter option causes the player to transmit the digital contents of the media “as-is” unconverted, down stream to the repeater (SP3) and the sink (TV). The “bitstream” option relies on the audio decoding being performed in the SP3, and ensures the highest quality. SP3 is capable of decoding virtually all common digital audio format including the latest lossless formats such as DTS-Master and Dolby TrueHD, thus it is recommended to use “bitstream” player setting.

Sample rate or “frame” rate (in this case “frame” and “sample” are synonyms) is the frequency of the digital data frames. For example 44.1kHz is the repetition frequency of the whole data frames transmitted from a standard Compact Disk (CD). One data frame is 16 to 24bits of digital data. Typical sample or frame rates are 44.1kHz (CD), 48kHz (DVD), 88.2kHz (SACD), 96kHz (high end digital sources),

176.4kHz, 192kHz – future very high resolution audio sources. Frame rate shouldn’t be confused with the bit clock rate which the clock frequency of the bits within each data frame. For example, for CD disk the bit clock is 2.822MHz.

This is a part of the HDMI adaptive filter configuration feature. The sink measures the electrical quality of the cable during handshake and can block transmission that is exceeding a capacity of the cable, forcing the source to downgrade the stream to a lower resolution settings.

1. Introduction.

Subwoofer output carries a combined (sum) contents of bass extracted from all the other speaker channels, for those speakers that are declared as “Small”, and also includes the Low-Frequency Effect contents (LFE) present optionally only in the multi-channel stream (labelled as 5.1, 6.1 or 7.1).

Bass contents is defined as the portion of the audio spectrum of frequencies from all the channels that are below the cross-over frequency (default is 80Hz), added up to the LFE channel (if present). The cross-over frequency can be modified in the SOURCE SETUPCROSSOVER Fc submenu, separately for the front speakers, center, surround and back. The LFE channel cannot be altered or cut off setup or Xtra Bass setup does not affect it.

and the cross-over frequency

Bass contents carried through those channels where the speakers are declared as “Large” is not re-routed through the Subwoofer. Instead it is output through those speakers directly.

If Subwoofer is declared as not present, then the bass contents from all the channels will be re-routed through the large speakers only (if there are any), otherwise it will be cutoff.

SP3 provides a single subwoofer channel through back panel RCA socket paralleled with an XLR socket. Optionally, it can also output the subwoofer channel through the Aux R socket.

2. Speaker Configuration.

Speaker configuration involves declaring the size such as Large

, Small or None (see SPEAKR SIZE menu) for the five categories of speakers: Front (Left and Right), Center, Surround (side surround), Back (rear surround) and Subwoofer (in SUBWOOFER submenu).

Except if subwoofer is declared as not present!

This is not normally enabled. The default Aux selection is Aux-L= down-mixed stereo Left, Aux-

R=down-mixed stereo Right (L SETUPMISCELLANEOUSAUX parameter.

A speaker is considered “Large” if it can reproduce bass down to 30Hz or lower. Anything else should be

entered as “Small”.

The difference deals with the Xtra Bass feature and is described in Section 4.

3. Subwoofer in 2-channel Bypass mode.

Two channel bypass mode is selected by the front panel button labelled “2 CH. BYPASS” and applies to analog stereo (left and right only) input signals. The signals are bypassing the Digital Signal Processor (DSP) and are routed only through analog preamps and analog volume control circuit. In this mode DSP can be completely disabled when the “in2BYPASS” option is OFF, or it can be used to extract the bass contents of the analog L and R input channels and output it through the Subwoofer sockets. When “in2BYPASS” option is ON then the cross-over frequency used for bass extraction is the one set up in:

SOURCE SETUPCROSSOVER FcFRONT, while the Subwoofer Volume

Level correction is the one set up in:

SOURCE SETUPSPEAKR LEVELSUB

SPEAKR LEVEL correction values are normally entered during or after the “Pink Noise” test, which is or will be described in a separate document. In most situations only the subwoofer level correction need to be applied specifically for a given subwoofer efficiency and gain.

Cutoff frequency may need be changed only if the speakers are unusually small with higher bass cutoff than 80Hz, or if they are medium size with lower than 80Hz cutoff but significantly higher than 30Hz (30Hz would be “Large”).

APPENDIX G: SUB-WOOFER SETUP continued

4. Xtra Bass feature.

If Subwoofer is present and the Front speakers are declared as Large then bass contents will be streamed through the Front speakers while only LFE will be reproduced through the Subwoofer. In this case, in order to make the subwoofer reproduce bass from the Front speakers as well, in addition to being reproduced by the Front speakers, Xtra Bass option can be enabled. Xtra Bass option has no effect and is disabled when the Front speakers are declared Small or when no subwoofer is present. Xtra Bass option has no effect on LFE reproduction.

With the Front speakers Large, Xtra Bass option can be enabled by setting the following parameter to ON:

SOURCE SETUPSUBWOOFERXTRA BASS

In addition, the mixing volume level of the bass contents can be adjusted by this parameter:

SOURCE SETUPSUBWOOFERLEVEL

The adjustment range is -20dB to 0dB. The LEVEL parameter applies only to Subwoofer in Xtra Bass (on top of the normal Subwoofer Level correction from SOURCE SETUPSPEAKR LEVEL). It is disabled and not applied if Extra Bass is not ON.

5. Interpretation of the x.1 and x.0 symbols on the SP3 idle screen

“IN:…” line:

Symbol ".1" or ".0" (as in 5.1 in the “IN: DdDigital 48k 5.1” above) indicates a presence or an absence of the LFE channel in the input stream. This is independent on the SUB selection in the SOURCE SETUP menus. It reflects the status flags embedded in the digital input stream. The actual flags can be read in hexadecimal format in SYSTEM SETUP-->TESTS-->SYSTEM STATUS: SIGNALFORMAT

“OUT:…” line:

Currently in firmware release 2012.05e, Xtra Bass feature only applies to 2 channel analog, digital and HDMI sources. It is not active for multichannel 5.1 or 7.1 sources, even if enabled., and is not applicable in bypass modes. In the future release this limitation will be lifted.

LFE will always be reproduced only though either the Subwoofer if present regardless of the size of the

Front speakers, or through the Front speakers if Subwoofer is not present and the Front speakers are Large.

Page 44

SubWoofer Setup Page 4 of 4

APPENDIX G: SUB-WOOFER SETUP continued

Symbol ".1" or ".0" (as in the “OUT: PL2xMovie7 EX 7.1” above) indicates a usage or a

lack of usage

of the Subwoofer speaker and is a function of the output configuration and

the presence of the input LFE channel. There are two cases:

a) Front speakers are Small:

If you select Subwoofer ON, then you will always see OUT:… .1 - indicating that the subwoofer is being used.

If you select Subwoofer OFF, then you will always see OUT: ... .0 - indicating

that the subwoofer is not used (bass contents will be lost).

b) Front speakers Large:

If you select Subwoofer ON, XTRA BASS OFF, and if the input stream does not

contain LFE channel (IN: .. .0) - then you will see OUT: ... .0 - indicating that

the subwoofer is not being used (all bass contents is being reproduced through the front large speakers).

If you select Subwoofer ON, XTRA BASS OFF, and if the input stream

does contain LFE channel (IN: .. .1) - then you will see OUT: ... .1 - indicating

that the subwoofer is used (all bass contents is being reproduced through the front large speakers but LFE goes through the Subwoofer).

If you select Subwoofer ON, XTRA BASS ON - then you will see OUT: ... .1 -

indicating that the subwoofer is used (all bass contents is reproduced through the front large speakers and the Subwoofer at the same time, while the LFE if present goes through the Subwoofer only.

A usage or no usage of the subwoofer channel is not equivalent of stating that the signal is or is not present. If the subwoofer channel is indicated as being “not used” (.0) then there is no signal but if it is .1 then the presence of a signal depends on the actual input stream contents.

APPENDIX H SETUP USING LOCAL AREA NETWORK

SP3 and PC Setup for LAN

(draft doc 16/12/2011, Stan B., Bryston)

1. General guidelines (introduction).

SP3 can be connected to a PC (Windows, MacOS, Linux etc) using Ethernet cable connected to a local area network hub or a direct peer-to-peer crossover network cable, using either one of the 3 basic configuration schemes differing in the way the IP addresses are leased out or assigned. This is called “Dynamic Host Configuration Protocol” service (DHCP), see

http://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

a) Static host IP and static SP3 IP.

This method is described in more details below in section 2. In most configuration where the LAN card of the host PC is set up for static IP address, SP3 would connect regardless of the DHCP selection, though “STATIC IPadr” is recommended. “NetBios Name” addressing cannot be used in this scheme (for example http://sp3-123 for example: http://169.254.1.1

b) Automatic IP host and server SP3 using direct peer-to-peer cross-over cable.

“Obtain an IP address automatically” is typically the default configuration in Windows PC. In this case, SP3 should be setup as either SERVER&CLIENT (this is the default settings). It would also work under the DHCP SERVER selection.

NOTE: plugging the SP3 set up as DHCP SERVER or SERVER&CLIENT into another server based LAN (for example a typical corporate LAN) may cause some

other DHCP servers to shut down1. Therefore this scheme is recommended only for direct peer-to-peer connections, not for server based LANs!

“NetBios Name” addressing cannot be used in this scheme (for example http://sp3-123 be addressed using its actual IP address that is for example: http://169.254.1.1

c) Automatic IP host and client SP3, both connected to the same LAN with an already established router or a network server.

“Obtain an IP address automatically” is typically the default configuration in Windows PC. In this case SP3 must be setup as DHCP CLIENT Auto IP

Some MS Windows Server 2003 server configurations may not automatically restart their DHCP services, which requires an administrator intervention. On the other hand almost all home network routers would automatically restart their DHCP after a clash.

DHCP SERVER&CLIENT selection would also work but is not recommended on corporate LANs due to a possibility of DHCP server disruption, see the footnote above.

would also work (however, the actual IP address value is determined by the DHCP lease event and may vary).

2. SP3 setup for static host and static SP3.

This setup uses peer-to-peer physical connection using a cross-over

Ethernet cable, connecting the Ethernet port on the back of SP3 unit, directly to the second LAN2 card in the host PC. To set up the SP3, press right arrow key to enter the menu system, then: SYSTEM SETUPMISCELLANEOUS Scroll to the third screen down:

TCP/IP setup screen

Make sure that the setup screen looks on like above screen4. After making a new DHCP selection press left arrow key to escape back to the main screen, then press STANDBY button and then again to power up, to reset the SP3 unit.

3. Host PC setup for static IP address.

Ideally, a second network interface card (LAN2) would connect only to SP3, while the main network card (LAN) would maintain the normal network and internet connectivity. An example of the interface configuration is showed at the right:

Some network card allow using standard (non-cross-over) Ethernet cables.

It is possible to edit and change the Ipadr or Ipmsk values but it should not normally be needed.

APPENDIX G: SETUP USING LAN continued

In order to ensure that the main LAN connection is not disrupted by the presence of a local side subnet, the main LAN card may require specifying a proxy server, and at the same time the static SP3 address must be excluded from the proxy, as showed in the following screen dump:

APPENDIX I DOLBY VOLUME/DRC SETUP

DOLBY VOLUME/DRC Screen

2012-08-02

Stan Bleszynski, Bryston Ltd.

1. Bringing up the Dolby Volume/DRC screen.

Pressing a down arrow key while the default (idle) screen is being displayed brings up the Dolby Volume screen for a about 10 seconds. After 10 seconds the screen reverts back to default (or when the up or left arrow is pressed).

The screen shows only one active parameter selection line:

Line 2: DYN RANGE FULL OFF

This setting (power up default) indicates that the dynamic range is full, in other words no dynamic range compression is engaged (DRC=OFF). A selection made using this screen will remain persistent after the screen times-out back to the default display. The Dolby Volume/DRC selection will persist for as long as the source is not switched over (for example from DVD to CBL/SAT etc) and as long as the unit is not powered off or standby’ed.

2. Available selections.

Turning a volume control knob or pressing the SURROUND MODE left and right arrow keys causes the following selections to scroll in line 2:

DYN RANGE FULL OFF

default)

Dd VOL LOW FULL MODE - Dolby Volume is ON in low strength, that is the

audio dynamic range is slightly reduced. The “Full Mode” (as opposed to “Half Mode”) means that Dolby Volume algorithm applies both audio compression and spectral equalization.

Dd VOL MED FULL MODE - Dolby Volume is ON, medium strength

(dynamic range is moderately reduced). The “Full Mode” means that Dolby Volume algorithm applies both audio compression and spectral equalization.

- all dynamic range compression is off (power up

It is possible to change this to be persistent through a factory setup.

This is equivalent to DYNAMIC RANGE FULL selection in SP1.7, SP2

SP3 Dolby Volume/DRC Screen Page 1 of 3

Page 50

APPENDIX I: DOLBY VOLUME/DRC SET continued

Dd VOL HIGH FULL MODE - Dolby Volume is ON, high strength (dynamic

range is highly reduced). The “Full Mode” means that Dolby Volume algorithm applies both audio compression and spectral equalization.

Dd VOL LOW HALF MODE - Dolby Volume is ON, low strength (dynamic

range is slightly reduced). The “Half Mode” (as opposed to “Full Mode”) means that Dolby Volume algorithm applies only audio compression but not spectral equalization.

Dd VOL MED HALF MODE - Dolby Volume is ON, medium strength

(dynamic range is moderately reduced). The “Half Mode” means that Dolby Volume algorithm applies only audio compression but not spectral equalization.

Dd VOL HIGH HALF MODE - Dolby Volume is ON, medium strength

(dynamic range is moderately reduced). The “Half Mode” means that Dolby Volume algorithm applies only audio compression but not spectral equalization.

DYN RANGE MEDIUM 1

– Dolby Volume is OFF but older DRC algorithm (Dynamic Range Compression) is ON resulting in medium dynamic range (moderate compression)

DYN RANGE LOW 2

– Dolby Volume is OFF, DRC is ON producing low

dynamic range (high compression).

DRC AUTO(THD,DTSHD) – Dolby Volume is OFF, DRC is ON, high

compression conditional upon the presence of DYNF flag in the digital source stream.

3. Additional configuration options for Dolby Volume.

When any of the Dolby Volume selection is made, that is if line 2 selects anything from Dd VOL LOW FULL MODE to Dd VOL HIGH HALF MODE (and only those) then the additional configuration settings are displayed in the lines 3 and 4 on the screen:

Line 3: Dd VOL OFFS 0.0dB - use volume knob to adjust Dolby Volume level offset

–20.0..+20.0dB. This parameter defines the maximum sound level for the

This is equivalent to DYNAMIC RANGE MEDIUM selection in SP1.7, SP2

This is equivalent to DYNAMIC RANGE LOW selection in SP1.7, SP2

APPENDIX I: DOLBY VOLUME/DRC SET continued

recording (as it should have been listened to originally, in a studio etc). For example, when listening to a movie, this value could be increased5initially during the loudest portion of the recording, to set the reference for the loudest parts. A positive VOL OFFS value makes the average output sound less loud, negative value makes it louder.

Note: Dd VOL OFFS does NOT have to be continously adjusted during a playback; this is an optional once-off (per movie) adjustment!

Line 4: Dd VOL MID/SIDE OFF – use volume knob or SURROUND left/right arrow to

toggle this parameter ON or OFF. MID/SIDE is relevant only in STEREO mode and causes Dolby Volume algorithm to automatically re-balance the left and right channels. Default is OFF.

Note: Dolby Volume algorithm is operating only at lower sample rates <=48kHz. It is automatically disabled above 48kHz but this is not indicated on screen!

No configuration settings are available for DRC selections.

+6dB is often sufficient to adjust the loudest movie scenes down to a comfortable level.

APPENDIX J FIRMWARE UPLOAD INSTRUCTIONS

SP3 Software Upload Instructions Page 1 of 6

Instructions for uploading the SP3 software.

4-Jan-2013

1. You must have the SP3 connected via Ethernet cable to your local area network

and powered up, or connected directly to your laptop or PC with a network cable. Make sure that a green light at the SP3 network socket (back panel) is lit. If not then use a cross-over cable or verify that the network interface to which SP3 is connected, is enabled.

2. Open a Browser on your computer (Explorer/Chrome/Safari etc)

3. Type:

http://sp3-serialnumber/upload

http://xx.xx.xx.xx/upload

where xx.xx.xx.xx is the actual IP address of the SP3

4. Optional - if the sp3-serialnumber method does not work then use the actual IP address as above, for example:

http://169.254.1.1

The serial number of the SP3 as well as the actually used IP address (for example

169.254.1.1 ) are available to view by pushing the left hand navigation button on the SP3 front panel, when the front panel shows the main (opening) screen:

7. After selecting the SP3.bin file, click on the “Upload” button in the “File Package Upload” window:

“File Package Upload” page of the SP3.

Note: If the internet connectivity is not available, then a “file not found” or other error will be shown and the process will be terminated. In such a case a local SP3.bin file must be selected. The file can be obtained by post or email from Bryston technical support and copied into a local directory.

The file upload starts after a few seconds (The file is read from a remote server and that requires internet connectivity!)

Some browsers1might not indicate the upload progress count, however, the Standby LED in SP3 will be blinking and the display on the SP3 will indicate the upload count status.

Wait2until the file gets uploaded to SP3 and until the self-programming process is

completed.

SP3 will automatically load, self-program and re-power up after the

programming is finished.

Software update process consists consists of 3 cycles:

Chrome browser does indicate the file upload count in %, in the status line at the bottom of the window.

Tpically about one to two minutes. Ignore error messages that may appear in the browser window during

programming stage, due to time-out.

Uploading is marked by a live time count on the SP3 front panel screen but during the last self programming stage the screen goes blank while the Standby LED will be flashing some red, yellow and green patterns (or red, violet and blue). Do not power off while self-programming is taking place!

SP3 Software Upload Instructions Page 4 of 6

a) SP3.bin file uploading (about 1minute). During this stage the FIRMWARE UPLOAD screen is displayed showing the progress count in seconds, bytes remaining to be transferred and status. The unit will only respond to a limited number of commands and buttons, namely: Left Arrow and Standby button to cancel the process. When the process is cancelled at this stage, it returns to the main screen and the unit can operate as the audio processor as before with the exception of web controls. Cancelling of a pending upload may leave some internal web source files missing, preventing the main SP3 web control page to work. In such a case the only web interface part that is guaranteed to work is the upload page: http://sp3-xxx/upload

restarted and allowed to finish.

b) Internal self-programming cycle (about 1 minute). The screen and all LEDs except standby are blank and the SP3 unit undergoes internal self-programming cycle of its control processor using the newly uploaded SP3.bin firmware file. This stage cannot be interrupted! The progress of the self-programming can be followed observing the standby LED blinking pattern. In the first (file verification) stage the LED blinks in short pulses interspaced by long (few sec) gaps, in the second stage (self-erase) it goes yellow or magenta for a couple of seconds, in the third stage (self-program) it stays green or blue for about 10 seconds.

If the original firmware is older than 2012.05e and SP3 unit is unpowered during the internal self-programming cycle, while the LED is yellow(pink) or green (blue), then it may be rendered inoperable, requiring a factory reprogramming service4.

c) Reboot and “idle test” of the newly programmed software (20s). The unit shows a standard power up logo screen, then the main screen. The first 10 seconds following the boot is the so-called “idle test” marked with the Standby LED staying on (yellow or magenta). If the unit crashes or is accidentally powered off during this time, then the system will reprogram itself yet again on the next power up, restoring the factory backup software (factory backup release number is prefixed with ‘f’, for example f2012.05).

Do not unplug or power off the unit and wait ten more seconds for the Standby LED to go dark after the main screen shows up, before using the SP3. Press the left arrow on the front panel to display the serial number and firmware revision, verifying that the revision number has been updated to a new value.

8. Comments regarding the 2012.11 or later firmware upgrade and re-defaulting of system parameters.

Applies only to bootloader version 2011.32 and earlier. Bootloader version number can be viewed in SYSTEM SETUP-->TESTS-->SYSTEM STATUS screen. More recent bootloader versions from 2012.05 onwards are able to recover from accidental power off at any stage.

Page 56

APPENDIX J: FIRMWARE UPLOAD INSTRUCTIONS continued

SP3 Software Upload Instructions Page 5 of 6

Firmware revision 2012.11 and later do not automatically redefault internal configuration

parameters and setups, therefore upgrading from a firmware earlier than 2012.05e may

cause software errors after power up, if a parameter introduced in the latest revision did

not exist in the old revision being replaced. If that happens upgrade first to revision

2012.05e ( ftp://bryston.com/pub/firmware/sp3/2012.05e/SP3.bin

) which will reset all

If the upload followed by self-programming fails for whatever reason

, then the system reverts to factory default which has a suffix 'f', that is in this case the firmware revision reads as f2012.05e (or earlier) but functionally it is identical to the firmware with 'u' prefix. If the bootloader reverted the firmware to a factory backup, it is recommended to upload the new firmware file again and to watch the sequence of events. The upload should last about 1 minute, followed by a reboot (all automatic, it is not necessary to press anything). Then the screen will remain dark for another minute or so, while the standby LED begins flashing a multicolor codes - first a few short blink codes, followed by about 1 second long yellow or magenta (erase stage) followed by a few seconds of long red (self-programming stage). Then the system will attempt an automatic restart, the screen will show the boot logo picture, then the new firmware revision number and then the normal idle screen will show up. However, the standby LED will remain lit yellow or magenta for another 10 seconds while executing an automatic self check. During that time it may optionally, automatically reprogram the keypad processor - do not power off at this stage! If the new software crashes during the time when the standby LED was lit, or if the processor gets unplugged or if another upload is started from the ethernet link by accidentally restarting the upload sequence (for example, pressing browser "Reload/Refresh" button), the self check may fail which will force the bootloader to reload the factory backup firmware on the next power up.

Firmware 2012.11 or later, do not automatically redefault the system configuration parameters (in EEPROM memory) like the previous updates. This may potentially cause a startup failure if some newly introduced parameters are not initialized, it also depends on the old configuration status. This should not happen when upgrading from 05e but may happen with some older revisions prior to 05e. In such a case it is recommended to upgrade first to revision 05e. Use:

ftp://bryston.com/pub/firmware/sp3/2012.05e/SP3.bin

The first time 2012.11 boots after upgrading from 05e, it will display a message on screen:

EEPROM is incorrect! Run MISCELLANEOUS->

DEFAULT EEPROM

Most frequent cause are: an incomplete file transfer due to network errors, breaking browser connection by accidentally exiting it in the middle of a transfer, inadvertently refreshing browser upload page in the middle of a transfer or immediately after the first new boot-up when the standby LED is still lit, or accidental power down.

It is recommended to follow it, that is go to Miscellaneous menu, and scroll down to DEFAULT EEPROM option

, press Surround arrow key to select "DO IT" and execute the action by exiting the screen, pressing left arrow. Alternatively, the user has a choice to navigate to the configuration menus in order to write down (or memorize) the preexisting configuration, so that the old settings can be manually re-inserted after the redefault.

A fresh 2012.11 upgrade may results in some EEPROM related error messages to be displayed in the SYSTEM SETUP-->TESTS-->SYSTEM STATUS screen, which should clear after executing DEFAULT EEPROM and re-powering (re-plugging)

the

unit. It is recommended not to use revision 2012.11.

Firmware revisions 2012.12 and later, have restored the automatic EEPROM redefault following an upgrade, due to frequently encountered problems involving uninitialized or mis-initialized parameters.

It is strongly recommended to use the latest firmware revision!

1. Bryston Serial Protocol command set for SP3.

SP3 receives control commands and responds back to the host controller following an execution of each command. SP3 can also be configured automatic responses through RS232 or TCP/IP upon certain system events such as input source switching or volume level setting from the front panel or by IR remote controller. The following commands can be sent over RS232, RS485 (with a RS232/RS485 interface) and TCP/IP (using GET mechanism over port 80).

RESPONSE FORMAT

The Response format is the same as commands, repeating the D1,D2,C and P bytes (P bytes may carry either an actual status value or ?? in case of errors).

Example (TCP/IP):

window, on a host PC connected to SP3 serial port

, by issuing a single-character special

question mark command ? :

If you use a network connection ithout a server or router, type in the actual IP address instead of the “sp3-

<ser.num>”

Default baud rate is 9600bps, 1 start bit, 8 bits, no parity, 1 stop bit. A baud rate and a feedback selection

can be set by MISCELLANEOUSRS232 BAUD and RS232 MODE parameters. Typing a ? is a convenient way of testing the connection.

Ending of a command by a dot character is not necessary when typing it in the SP3 web interface window, but mandatory when issuing the GET command programmatically or from a browser’s URL window. Pressing a carriage return key while the SP3 web page is in-focus is equivalent of clicking on Cmd button icon.

2. Communication through RS232 port.

All commands described in the helpcmd.txt or helpcmd.htm file can be sent through the serial port, receiving the response of up to 320 characters. It is recommended to test the RS232 communication link using a PC running a serial terminal program, before connecting to a dedicated controller box. An instruction on how to connect the serial port on SP3 and a list of some commonly available third party freeware or shareware terminal programs is in this document:

ftp://bryston.com/pub/firmware/sp3/doc/SP3_RS232_Notes....pdf

3. Communication through Ethernet port. TCP/IP HTTP-GET

a) Sending a command through URL and a browser.

Before testing this method, bring the SP3 virtual panel web page on screen to make sure

that the LAN connection is established. For example, type in an actual IP address

of the

SP3: http://169.254.1.1

Next, send an HTTP GET command directly, from a URL window of a browser or from within a web-aware application supporting HTTP protocol. For example

http://169.254.1.1/cmd.cgi?cmd=%2310MPWR01 http://169.254.1.1/cmd.cgi?cmd=%2310MSRCQS

. .

Note: the hash character # must be replaced by the equivalent URL encoding of %23 . The dot character at the end of the lines above is significant and acts as the end-of-command terminator replacing the <CR>.

Above sequences passes commands from the host to SP3. In order to pass data in the reverse direction, from the SP3 to host, type the following text into the URL window and press Enter

: http://169.254.1.1/status.xml This will cause the SP3 system status data to be read from the SP3, including a response from the previously sent control command (in this case MSRCQS), to appear in the main browser window, for example:

The actual IP address can be viewed on the serial number screen displayed by pressing the left arrow

navigation key on the front panel or IR remote.

For the power up command to work over TCP/IP out of the standby state, Ethernet interface must be

enabled using MiscellaneousETHERNET IN STBY: ON setup. Default is OFF. To access that parameter setup scroll down Miscellaneous menus then unlock the hidden screens pressing ZONE, DVD and TAPE buttons in this order, or issue code 222 on the BR3 infrared remote. Only RS232 is always enabled by default and works in standby state, although only MPWR and INFO commands are supported in standby.

The “Enter” key works only on desktop operating systems such as Windows7, MacOS etc. On tablets

running Android, iOS etc, one must tap CMD icon instead, in order to send a command.

through status.xml data block.

APPENDIX K: SP3 CONTROL VIA RS232 & TCPIP continued

b) Sending an HTTP GET command through Telnet terminal window.

First start Telnet service by:

>telnet IP 80

Where 80 is the port number (always use port 80) and IP is the actual IP address of the SP3 unit, for example 169.254.1.1. Next, send the following packet (for example type it into a Telnet terminal window):

GET /cmd.cgi?cmd=%2310MSRC05. HTTP/1.0

or send the same packet as above directly from a Telnet-like application program using Telnet GET command protocol to port 80. Above sequence passes a command (in this case selection of input source “MSRC”) from a host to SP3. In order to pass data (i.e. command response) in the reverse direction, from the SP3 to the host, type the following into the Telnet terminal window and press enter: GET /status.xml HTTP/1.0 This will cause the incoming data read from the SP3 appear underneath, for example:

Using GET status.xml to read system status and command response from SP3.

The response is contained within the tags: <tw0>..<tw0> to <tw7>..<tw7> .

Pink Noise Test 2012-03-05 Page 1 of 4

APPENDIX L SP3 PINK NOISE TEST

SP3 Pink Noise Test

5-March-2012, Bryston Ltd., Stan Bleszynski

1. Introduction.

Noise Test features allows adjusting and correcting relative speaker efficiencies by

Pink playing the noise sound of known and constant intensity through each speaker channel, while recording the sound pressure with a sound pressure meter2.

2. Starting the Pink Noise test from the Front panel:

Go to SYSTEM SETUP-->TESTS-->PINK NOISE

If you press right arrow again it will go into the "Pink Noise" screen (see above) and will start playing the noise in the AUTOCYCLE mode, that is it will go through all the enabled speaker channels3for a few seconds each, repeating ad infiniti. To exit press the left arrow or power/standby button. Bottom line label “SETVOL:” indicates that it is possible to adjust the global volume level (-80dB to +12dB) with the volume knob – that is the case only when the Left Front speaker channel is playing!

Adjusting volume level while other than the L channels is playing, only changes the specific Speaker Level offset within -12dB to +12dB range (as in SOURCE SETUP->SPEAKR LEVEL screen) rather than the global volume! This situation is shown on the screen below where the bottom line label changed to “SPK LEVEL:”

The term “pink noise” as opposed to “white noise”, refers to the spectral characteristics of the sound, where the spectral power density is higher for lower frequencies, or more specifically each octave carries an equal amount of power (see http://en.wikipedia.org/Pink_noise ).

Sound pressure meter is an external accessory not included with the SP3.

If all speakers are enabled then it will go through L,C,R,Rs,Rb,Lb,Ls and Subwoofer (subscript s means “side surround”, b – “back surround”). Disabled speakers - those configured as “None” in the SOURCE SETUPSPEAKER SIZE, are skipped.

Pink Noise Test 2012-03-05 Page 2 of 4

APPENDIX L: SP3 PINK NOISE TEST continued

Note: instead of adjusting volumes while playing noise and reading the sound pressure at the same time, it is probably easier to write down the sound pressure readings for each speaker channel and then adjust the corresponding speaker levels in the SOURCE SETUP-->SPEAKR LEVEL submenu. After adjustment, it is recommended to verify it by rerunning the noise and retesting the sound pressure levels.

3. Starting by TEST button on the infrared remote controller.

SP3 goes to the "Pink Noise" screen and starts playing the noise in the AUTOCYCLE mode, the same as when selecting it by the front panel through TEST submenu, except that it will exit automatically after the last speaker channel in the sequence (typically subwoofer) finished playing.

If one presses TEST button again while any of the channel is playing noise in AUTOCYCLE mode, the AUTOCYCLE mode changes to MANUAL mode (see below). Once in the MANUAL mode, pressing TEST button each time increments the speaker channel through the entire sequence of enabled channels (L,C,R,Rs,Rb,Lb,Ls and SUB, skipping disabled channels).

Global volume level (-80 to +12dB) can be adjusted when the first channel (L) is played, while the individual speaker levels (-12 to +12dB) can be adjusted while the other channels are playing. The test ends when the last channel in the sequence has played or when the left arrow key is pressed (or POWER is toggled) .
