Introducing the SP 1.7 Reliability & Suppor t

OUR GOAL

With the SP 1.7, we have sought to design an uncluttered,

easy-to-use processor/preamplifier, incorporating stereo and a

full range of surround sound capability, which delivers state-of-

the-art performance in both analog and digital formats.

PERFORMANCE WITHOUT COMPROMISE

With today’s increased clarity and dynamic

range in recordings and movie sound-

tracks you need equipment that not only

equals but surpasses the parameters of the

most demanding material available. The

SP 1.7 preamplifier/processor is without

peer in meeting this performance challenge.

EASY TO USE

The Bryston SP 1.7 is the first high-end processor designed to

make home theater easy for the non-technical user. For example,

most functions are automatic, controls are well-labeled, and

there are clear unambiguous LCD and LED displays. Step-by-

step set-up menus with error messages displayed on the LCD

window, and a user-friendly, yet comprehensive user manual,

make the initial set-up simple and straightforward.

HOME THEATRE PROCESSING

In the digital mode, the SP 1.7 automatically detects the digital

input signal, routes the signal through the DSP module, and

adjusts to the appropriate mode. The digital circuit provides

decoding for Dolby Digital, Dolby Pro Logic, DTS

and THX formats, in 5.1, 6.1 and 7.1 channels.

There’s also Mono and Stereo Down-mixing

for all modes, Bass Management

modes for all speaker setups.

ANALOG AND DIGITAL CONTROL

The SP 1.7 puts you in control of a full range of input/output

options, allowing a choice of 13 sources, with 6 digital inputs

(4 - coaxial & 2 -

TOSLINK; (Pro model, single AES/EBU replaces 2

- TOSLINKS), 6 stereo analog inputs, and a set of 6 inputs for a

5.1 analog output. A Digital toggle button lets you switch easily

between digital and analog input signals, and there is a built-

in 24/96

D/A processor. The SP 1.7 provides both

In addition to stan­dard 5.1 surround,

the SP 1.7 allows for

6.1 and 7.1 in EX and
ES modes.

unbalanced outputs (

RCA) and a set of 6 true balanced

outputs (

XLR) for 5.1 and stereo, each with its own discrete

output amplifier. Balanced signal transmission uses common-

mode rejection to prevent induced hum and interference

even with long cable runs.

STEREO PREAMPLIFICATION

While the SP 1.7 is a great multi-channel controller, there

are those who still like their stereo in the analog realm; so,

at the touch of a button, the digital circuitry can be

bypassed and SP 1.7 operated as a Bryston audiophile-

quality analog pre-amp. The bypass mode provides a

totally discrete analog signal path — including an analog

volume control. The signal does not go through any IC’s or

digital circuitry from input to output.

DIGITAL SIGNAL PROCESSING FOR MUSIC

The SP 1.7’s DSP music modes allow you a range of

options to enhance the acoustic ambience of your listening

room: Stereo5, Natural, Club, Stadium, Hall, Theatre,

Church, and Party.

SONIC SUPERIORITY BY DESIGN

The Bryston Design philosophy ensures sonic superiority. All

analog signal circuitry is fully discrete to avoid the phase

shift and nonlinearity inherent in ICs. We exclusively use

only the finest components, such as 1% metal-film resistors,

polystyrene capacitors, hand-matched transistors, and

gold-plated

RCA and XLR connectors to reduce noise and

distortion to the absolute minimum. Two completely sepa-

rate and independent power supplies are employed to

prevent any possibility of digital to analog crosstalk or

interference.

THE RESULT

Of course, the purpose of all this technology is to place you

within the scene of the movie, or to transport you to the

actual musical event. Whether you can experience all the

drama, movement, and emotions intended is the one truly

meaningful measure of any audio/video system. Take the

time to visit your Bryston dealer and audition the Bryston

SP 1.7 preamplifier/processor. We think that you’ll redis-

cover how exciting audio can be.

The SP 1.7 analyzes the digital bitstream,

determines format, automatically adjusts mode,

and provides a readout on the LCD screen.

Balanced outputs are ideal

for long cable runs to active

loudspeakers, reducing

induced hum and noise.

Right PMC model AML-1 Powered
Loudspeaker offers a balanced input.

Two 12 volt trigger outputs allow for remote triggering

of your amplifier(s) or other home theater accessories

such as motorized drapes and screens.

Above Bryston 9B SST amplifier featuring trigger on/off and 5 modular
channels, each delivering 120 watts into 8 Ohms.

BUILT TO LAST

Bryston applies techniques and employs custom materials in

our everyday construction of electronic equipment that are

mor

e typically utilized in military and aerospace industries.

Our traditional adherence to proprietary parts and sophisticated

construction and testing techniques prevents the unit-to-unit

variability typical of mass produced product and assures that

your amplifier will perform for many years without concern.

HAND ASSEMBLED WITH CARE

All audio products we make are hand assembled and individu-

ally tested by a dedicated team of Bryston employees in our own

North American manufacturing facility.

UNIQUE BURN-IN PROCEDURE

Each and every Bryston audio product undergoes an extensive

quality control “burn-in” procedure. Following a complete oper-

ational checkout, every unit is placed on a test-bench and run

for 100 hours. This extremely rigorous burn-in quickly “matures”

components and weeds out any potential premature failures.

The result is reliable trouble-free performance for many years.

EASY FUTURE UPGRADES

We’ve designed the SP 1.7 with a plug-in ROM chip; this allows

for convenient upgrades so future software changes are quick

and easy to implement. On the hardware side, our pin-to-pin

compatible digital board topology facilitates upgrades to future

formats or digital processing technologies. The SP 1.7’s existing

DAC chips can run at sample rates up to 192kHz facilitating

upgrades to accommodate future formats. It is worth noting that

many manufacturers promise that their units will be upgradable

for future technology. Bryston actually does it (and is doing so

today, at moderate cost, for the SP 1.7’s predecessor).

ON-LINE CUSTOMER SUPPORT

The Bryston website allows for downloading of technical bulletins,

product addendums, and complete user manuals.

OUR 20-YEAR WARRANTY

Our commitment to build-quality and to quality control is why

every product we manufacture features an unlimited, transferrable

20-Year Warranty, a warranty that remains unequaled by any

other audio manufacturer in the world.

Ths SP 1.7’s RS 232 port allows for the integration

of external control systems (AMX, Crestron, etc.),

and manages external video switchers, including

the new Bryston SPV-1.

• Audiophile sound quality and construction: all analog
gain blocks are fully discrete; premium components and
hand-matched transistors used throughout; two sepa­rate independent linear power supplies with toroidal

POWER

The SP1.7 uses a dual mode electrical power system. In the

electrical power input module located on the right hand side of

the rear panel, adjacent to the IEC power cord socket is a large

computer-style switch that controls the main electrical power to

the unit. This is the ONLY switch that actually completely turns

off all power to the unit. Please see the illustration adjacent.

When the SP1.7 is connected to an appropriate AC power

source, and the power switch is switched to the ‘I’ position,

the unit automatically sets itself into a STANDBY power mode,

where-in only the minimum necessary circuitry to respond to

the remote control’s power-on command or the momentary

power toggle switch on the front panel are active. The RED

standby LED on the front panel illuminates.

Activating the momentary POWER toggle switch (either up or

down) on the front panel or the POWER button on the remote

immediately takes the unit out of its STANDBY mode into its

normal operating mode.

The presence of AC power to the SP1.7 is indicated by the

illumination of the front panel LCD display, the illumination

of the LED corresponding to the source you last selected, and

the units LED operating mode indicators.

NOTE: If your unit’s LCD backlight does not illuminate

when the SP1.7 is plugged into an operating outlet, and

switched out of STANDBY mode, please check to see that

the rear panel main power switch {mains switch} is in the

ON position.

If the SP1.7 is to be unused for an extended period of time (i.e.

a vacation) it is strongly recommended that it be turned off

using the main power switch on the back panel.

FRONT PANEL CONTROLS AND INDICATORS

When looking at the front panel of the SP1.7 you will see the following

controls and displays from left to right:

1. Power [Momentary Switch]

Toggling this switch up or down takes the unit in and out of its’

Standby power mode.

2. Standby and (IR) Infrared Activity Indicator

If this LED is continuously red, it is an indication that the SP1 is

in Standby mode. When the SP1.7 is powered up, the LED is

OFF, and flashes (Red) when a valid IR code is detected.

3. (IR) Infrared Receiver/Sensor for remote control

4. Dynamic Range Control

This three position switch permits the adjustment of the dynamic

range (softest sound to loudest sound) of signal sources producing

a Dolby Digital or DTS encoded bitstream. The Dynamic Range

Control has no effect with PCM and Analog input signals.

4

Figure 3: Front Panel

5

USING THE DYNAMIC RANGE CONTROL

For the majority of applications this switch should be placed and remain in the middle or NORM position.

For late night viewing or at any time you wish to reduce the overall dynamic range of a program the switch

may be set to the “LATE” (down) position.

If you wish to turn off all of the software’s built-in dynamic range management functions the switch can be set

to the “MAX” (up) position.

NOTE: Caution should be exercised when choosing this option. Many smaller loudspeaker systems can-

not handle the extremely wide range signals produced in this mode. Overall system volume should be ini-

tially set quite low until you or your dealer are able to determine the maximum safe setting to avoid

damage to your loudspeaker systems or power amplifiers.

5. LCD Display window

Contains the two line, black on green 16 character per line alphanumeric display which indicates the status and

functional mode of the SP1.7. This screen is also used during the menu-setup function for calibration of the SP1

to your system. If connected to the Bryston SPV-1 Video Switcher, the menu-setup and status display will also

be available on your video monitor with On-Screen Display (OSD).

On the first line, the decoding type [Dolby Digital,

DTS, Pro-Logic, Music, etc.] is displayed. A sample

screen is shown below:

On the second line, the type of signal being detected

from the currently selected input is displayed. A sample

screen is shown below:

Figure 4: Status display showing
Dolby Digital 5.1 channel signal at input

Figure 5: Status display showing analog
input signal and Pro Logic decoding

6. Menu Control Buttons

These three buttons labeled “<”, “>”, and “SEL” (SELECT) are

used to control the menu/setup functions displayed on the LCD.

To enter a menu mode, you can press any one of these buttons.

This will bring up the main menu.

Navigating any menu or sub-menu is done using the two arrow

(< >) buttons. Once the desired submenu or function is high-

lighted, pressing “SELECT” will make it the current menu or

function.

To exit a menu, or back up a step use the arrow buttons (< >)

to highlight the ‘X’ displayed in the lower right hand corner of

the LCD window and press “SELECT”.

7.Source Selection Buttons and Indicators

Pressing any one of these buttons will instantly switch the

SP1.7’s analog and digital inputs to read the indicated source.

If the SP1.7 is in its digital mode, as soon as any input is

selected and switched, the decoder will automatically try to

determine the new bitstream’s type and mode.

MODE SELECTION BUTTONS:

8. Digital Mode and Indicator

This button operates as a three-way toggle function. The LED immediately

above the button has two colors - RED and GREEN, and an OFF mode

where it is not illuminated.

When Digital Mode is selected, the decoder will automatically default to a

digital signal for the selected input if one is present.

If a digital signal is present and detected, the SP1.7 will automatically determine

the type of bitstream and select the proper decoding mode. The indicator

LED will turn green when this happens.

If NO DIGITAL SIGNAL is detected the SP1.7 will default back to the analog

input for the selected source. This also automatically puts the SP1.7 into its

Digital Standby Mode. When this occurs the LED indicator will turn RED

In this mode, the decoder will continually check the selected source inputs

for the presence of a digital signal. If one is detected, the SP1.7 will auto-

matically switch over to the pre-selected digital operation mode for that source.

To defeat this auto-digital detect mode you must press the button again. If

you do the LED will go OFF.

When this mode of operation is selected the SP1.7 will look at ONLY its

analog inputs. If a digital signal does appear the SP1.7 will NOT recognize

it and will remain in its analog only mode until you press the Digital button

again to either select the digital source or place the SP1.7 into its auto detect

mode as explained above.

9. Surround Button

Pressing this button will engage the SP1.7’s surround listening mode. When

this function is operational the LED will turn green. For Dolby Digital 5.1,

DTS 5.1, and DTS-ES 6.1 bitstreams, the signal will be decoded and pre-

sented with no additional post-processing. For 2-channel source material,

the SP1 will synthesize surround information based on the chosen Surround

Mode (see 31. for Surround Mode information).

DIGITAL

SURROUND

10. Stereo and Stereo Downmix Mode

If this button is selected and the supplied bitstream is more than 2 channels, the

decoder will automatically implement a stereo downmix. Otherwise,

analog or digital two channel signals are passed as conventional stereo.

11. Mono and Mono Downmix Modes

If this button is selected and the supplied bitstream is more than 1 channel, the

SP1.7 software will create a Mono mix of all signals. If the centre channel is

present, the Mono signal will appear in the centre channel. If no centre channel

is present, the mono signal will appear simultaneously on the Left/Right speakers.

NOTE: Downmix [stereo or mono] is a software based automatic mixing
function available within the SP1.7. 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 Dolb y 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 producers can set and adjust the type

and ratios allowed for downmixing 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 mix-

ing coefficients for the centre and surround channel signals.

These will be detected by the SP1.7 and used to produce the downmix if this

mode is selected.

12. THX Button

Pressing this button will engage the SP1.7’s default THX listening mode. The default mode is selected using the

“EX Control” menu (see page 26).

NOTE:THX Surround EX™ decoding is only available in the THX listening mode.

If the “EX Control” Option is set to OFF, selecting this function (LED green) will automatically incorporate the

THX post processing option for all surround modes. Dolby Digital 5.1, DTS 5.1 and DTS-ES 6.1 bitstreams will

be decoded and presented with THX post-processing.

If the “EX Control” Option is set to ON, selecting this function (LED green) will engage THX Surround EX™

decoding for back channel speaker(s), and incorporate THX post processing, for Dolby Digital 5.1 bitstreams

only. For DTS bitstreams, the signal will be decoded and presented with THX post-processing. THX Surround

EX™ is only available if the back speakers are engaged. If THX Surround EX™ is unavailable, an error message

will appear on the LCD.

If the “EX Control” Option is set to AUTO, selecting this function (LED illuminated) will engage THX

Surround EX™ decoding only for bitstreams that are flagged as having EX encoded content.

NOTE: not all DVDs that are recorded with THX Surround EX contain this flag.

Pressing the THX button repeatedly will toggle between the ON and

DISABLE settings for THX Surround EX™. The default THX

mode will only be engaged when entering the THX mode from

another listening mode (such as Surround or Stereo)

For 2-channel source material, the SP1.7 will synthesize surround

information based on the chosen Surround Mode (see 31. for

Surround Mode information), and add THX post-processing.

NOTE: If the THX listening mode is engaged, PLII Music and
NEO:6 Music are not available, due to THX requirements.

(please SEE Appendix B FOR MORE Information about THX post processing)

THX

13. Mode Button

This button is used to select one of 13 effects for synthesizing surround sound with 2-channel source material.

Pressing the button repeatedly will scroll through the modes:

Available with THX Listening Mode…

■ PLII Film

■ Pro Logic

■ NEO:6 Cinema

You can select a Surround Mode for the Surround or THX listening

modes at any time, even if the effect is not immediately active (such

as the case when a 5.1 channel bitstream is present). Two Surround

Mode settings are memorized for each input – one associated with

the Surround listening mode, and one associated with the THX

listening mode.

14. Bypass Button

This button operates as a three way toggle function. The LED immediately

above the button has two colors - RED and GREEN, and an OFF mode where

it is not illuminated. The options are Bypass 2ch, Bypass 5.1ch, and Bypass Off.

Press the button once, and the unit goes in the Bypass 2ch mode. In this mode,

the LED will be GREEN. In Bypass 2ch mode all of the DSP circuitry, DA

and AD converters are bypassed, allowing a completely analog circuit path,

identical to the reference standard Bryston BP-25 pre-amplifier. Only

standard format Stereo operation is permitted in this mode - all other

functions are disabled. The Front Panel Stereo Balance control now

becomes active.

Press the button again, and the unit goes into Bypass 5.1ch mode. In

this mode, the LED will be ORANGE. In Bypass 5.1ch mode, the signal

from the 5.1 channel analog inputs (RCA) will be routed through the

volume controls and to their respective outputs, balanced and unbalanced.

No bass management is available with the 5.1ch bypass mode.

To defeat the Bypass mode, press the Bypass button again, and the LED

will go OFF.

15. Analog Balance

This control governs the balance of the analog bypass circuit. It will only

function if the SP1.7 is in Bypass 2ch mode.

16. Master Volume

This is the Large Knob located on the far right side of the front panel. It

controls the Master Volume in all modes. It is fully motorized and can be

operated from the remote control or by hand. It is the final level setting control

on the SP1.7, and determines what output level will be supplied to the

connected power amplifiers, but not the tape/recording outputs. It takes into

account any speaker level trim adjustments made during the SP1.7’s setup.

BYPASS

REAR PANEL INPUT AND OUTPUT CONNECTIONS

1. Balanced and 2. Unbalanced Outputs

The SP1.7 offers both balanced (5.1) and unbalanced (7.1) outputs for power amplifiers or powered loudspeaker

systems. The type you select to use will be determined by the input configuration of your amplifiers or self-

powered loudspeakers.

NOTE: XLR and RCA connectors can be simultaneously utilized. (Example - Surround f ill channels)
Back channel(s) are only available from the RCA outputs.

3. Analog Inputs

A paired stereo analog input with gold RCA jacks (labeled L and R, for Left and Right) is provided for each

source button on the front panel.

The sensitivity of these Inputs is set to the industry standard of 2 Vrms, which should accommodate the vast

majority of available source components. In Bypass mode, the input sensitivity is equivalent to the BP-25

preamplifier.

A 5.1 channel analog input is also provided on 6 RCA connectors. This is typically used for Multi-channel

DVD-Audio, SACD, or external processors. In Bypass 5.1ch mode, the signal from the 5.1 channel analog

inputs (RCA) will be routed through the volume controls and to their respective outputs, balanced and

unbalanced. No bass management is available with the 5.1ch bypass mode.

4. Digital Audio Coaxial Inputs

The TV/SAT, DVD, CD, and AUX front panel selectable sources are also supplied with a standard SPDIF gold

RCA jack digital audio input. These four inputs will accept any standard SPDIF source including DAT, CDR and

similar components.

5. TOSLINK Digital Audio Optical Inputs

The SP1.7 offers two assignable TOSLINK optical inputs. These can

be designated to any input using the OS menu (“Other Settings”)on

the LCD screen. Please note that if you choose to assign an optical

input to an input with a coaxial input, the coaxial will be over-ridden

and the optical input signal will be used by the SP1.7. The pro model

replaces the two TOSLINK connectors with a single AES/EBU

Digital connector.

Setting the Optical Audio Input Assignment

i. Enter the main menu by pressing on one of the menu buttons on the SP1 front panel. Move the cursor to “OS”.

Hit ‘Select’ - You are now in the ‘Other Settings’(Optical/THX) Menu.

ii. Move the cursor to the Optical Input

(OPT1 or OPT2) you want to change the

input assignment for. Hit ‘Select’.

iii. Now you can assign the optical input to any one of the 6 inputs selectors. Doing this will override the

digital coax connector on that input. Hit ‘Select’ when finished.

NOTE: On the pro model,‘AES’will show up in the ‘Other Settings’Menu (instead of OPT1 and OPT2),
to setup the AES/EBU input assignment.

6. Tape/Recording Outputs

The SP1.7 provides two analog outputs for the TAPE and VCR sources. The front panel selected input signal is

always routed to these tape outputs, except when TAPE or VCR is selected. In those cases the appropriate output

is automatically muted to prevent feedback.

AES/EBU

7. Remote 12V Trigger Outputs

Two trigger outputs are provided. The output labeled “ON/OFF” provides a 12V voltage level whenever the unit

is fully powered up. When the unit goes into standby, the level is 0 Volts.

The output labeled “AUX” is programmable from the LCD menu as described below. This means that the termi-

nal supplies the 12-Volt signal only when you switch to certain, specified inputs.

The Centre (Common or Ground) terminal is always used with the “ON/OFF” or “AUX” terminals to complete

the circuit loop. The 12-Volt connector will accept 1/4 - inch stripped wire ends, inserted into the square holes

provided, and the adjacent screws carefully tightened to hold them in place.

These can be used to control any Bryston Power amplifier and many other components such as motorized

screens and drapes. Be sure to determine what type of trigger signal the selected components requires and what

function will be enabled by the trigger signal’s voltage.

Programming the AUX Trigger Output

i. Enter the main menu by pressing on one of the menu buttons on the SP1 front panel. Move the cursor to

“OS”. Hit ‘Select’ - You are now in the Other Settings (Optical/THX) Menu.

ii. Move the cursor to “T”. (T = Trigger) Hit ‘Select’. Now you can assign the AUX Trigger output to ON or

OFF, for each of the 6 input sources.

iii. To change the source, use the “<” button. To toggle the trigger setting On or Off, use the “>” button.

SET UP and CALIBRATION OF THE SP1.7

NOTE: In most operating menu modes the last segment of line 2 of the display will either show an “X” for
EXIT, or an “>” (arrow) to indicate more menu items. (sample screens are shown below - fig 11,12).
Choosing (highlighting) the “X” position in the display and pressing the Select button (see below) will
“EXIT” back to the previous menu, or exit the menu mode entirely. If an “>” appears,continue pressing
the menu navigation arrow buttons to reveal more menu options.

In order to fully enjoy the capabilities of the SP1.7 you or your dealer must first set-up and calibrate the SP1.7.

This is a critical step in insuring that all your loudspeakers are properly designated within the unit and that all

levels and delays are properly set.

To accomplish this process the following tools are needed:

1. Tape measure or other means of determining the distance of each speaker from the chosen listening positions.

2. Sound Level Meter. This device insures that all loudspeaker levels are precisely matched and set accurately.

This step cannot accurately be done by ear, a test instrument should be used to ensure proper calibration. (The

Radio Shack Analog SPL meter is inexpensive and eminently suitable for this task. Your dealer may have one.)

IMPORTANT: When using the Pink Noise generator within the SP1.7 for speaker level calibration, the salient

point is that all channels measure equal dB. After pushing the test button, the pink noise will start in the front

left speaker. Record the dB level from this speaker (with the level trim value at 0 dB on the LCD Display or on

the Video Monitor when using the Bryston SPV-1), and adjust all the others to match it. It is not critical to reach

some specific dB level (ex. 85 dB), it is more important that all channels are at equal levels.

Please Note: If for any reason you are not sure that you can accomplish this calibration task or have any
doubts as to how it should be done, please contact your dealer or Bryston technical support BEFORE
attempting this process. Most Bryston Dealers can provide this service. Please contact your dealer for
their policies and procedures in this regard.

Explanation of ‘Saved Settings per Source’ Feature

The SP1.7 will remember different mode settings for each source. Every time a source is engaged it will recall

the following settings:

Digital Status

Listening Mode (Surround, THX, Stereo, Mono)

Surround Mode

Bypass Status

Subwoofer Level

Rear Channel Levels

Back Channel Levels

Speaker Configuration

EX Control

ES Control

To save these settings, make the preferable mode changes and adjustments per source, then press the SAVE

button on the SP1.7 remote control before switching to another input.

NOTE 1:You must set the speaker conf iguration manually for each input, within the LCD setup menu.

NOTE 2:The Setup Test Noise mode will overwrite Rear and Sub level settings for ALL inputs.

Setting the Speaker Configuration

Before calibrating levels you must first tell the SP1.7 about your loudspeaker configuration. To do this:

1. First enter the main menu by pressing on any one of the menu buttons (< - > or SELECT).

2. Next move the cursor to “SP”. Hit ‘SELECT’ - You are now in the Speaker Menu.

3. Move the cursor to the speaker(s) you want to change the configuration for using the arrow keys (LR, C,

SUR, BK, SUB). Hit ‘SELECT’.

Figure 14: Highlight “LR” in the Speaker Menu

Figure 13: Highlight “SP” in the Setup Menu

The options available in this menu are:

For LEFT/RIGHT (LR) you can select SMALL OR LARGE

For CENTRE (C) you can select SMALL, LARGE or NONE

FOR SURROUNDS (SUR) you can select SMALL, LARGE or NONE

FOR BACK (BK) you can select NONE, ONE or TWO

FOR SUBWOOFER (SUB) you can select YES or NO

The SP1’s default factory settings as shipped are:

Left/Right = LARGE

Centre = NONE

Surrounds = SMALL

Back = NONE

Subwoofer = YES.

If only one back speaker is chosen, the signal will be present on the BACK LEFT OUTPUT only.

4. Once you have completed selecting the settings that match your particular speaker systems please move the

cursor to the (X) and press SELECT to exit this menu.

NOTE: LARGE VS SMALL SPEAKER SETTINGS:

It is very important that you understand what is meant by the LARGE and SMALL settings in this menu. They

do not refer to SIZE, but to the ability of the particular loudspeaker system to handle low bass/low frequency

information. It is very important that you consult your loudspeaker providers instruction manual or the company

regarding the capabilities of your particular system with regard to low bass/low frequency reproduction. Please

note that all THX certified loudspeaker systems are SMALL since a subwoofer is a part of any THX certified

loudspeaker system. It is strongly recommended that you consider using a subwoofer for any system which you

expect to effectively handle the low frequency dynamics of modern motion picture soundtrack sources such as

DVD or HDTV feeds, and many other discrete multi-channel programming sources. If in any doubt choose

small, especially if you are using a subwoofer, since this will insure that all the appropriate low frequency

information is directed to the subwoofer where it can be most effectively handled.

Explanation of ‘Xtra Bass’ Mode

With any 2-channel material, there is no LFE (Low Frequency Effects, .1 channel) track. So, if your front

speakers are defined as ‘Large’, the subwoofer will be inactive because no bass is being directed there. The

Xbass mode allows the subwoofer to be active, even if the front speakers are full-range. You may find this is

particularly useful for Pro Logic movie soundtracks.

In the Speaker Setup Menu, under the SUB heading, there are 3 choices:

20

21

1. None: no subwoofer attached to the system.

2. Yes - Xbass Off: subwoofer is active, but only active with LFE tracks if the front speakers are full-range

3. Yes - Xbass On: subwoofer is active in system, in addition to full-range speakers.

NOTE 1:the Xbass settings only show up in the menu if the front speakers are defined as ‘Large’.

Otherwise, there are only two options,Yes and None .

NOTE 2:Xtra Bass operation is only available with Stereo, Stereo5, Party, Pro Logic, PLII Music, and

PLII Movie modes.

Setting the Speaker Crossover Frequency

1. First enter the main menu by pressing on any one of the menu buttons (< , > or SELECT).

2. Next move the cursor to ‘SP’. Hit ‘SELECT’ - You are now in the Speaker Menu.

Figure 15: Highlight “SP”

in the Setup Menu

Figure 16: Highlight “XO”

in the Speaker Config Menu

3. Next move the cursor to ‘XO’. Hit ‘SELECT’ - You are now in the Crossover Menu. The options available

in this menu are either NONE or 60 Hz to 220 Hz in 10 Hz increments. The SP1.7’s default factory setting

as shipped is the THX standard 80 Hz crossover frequency.

4. Once you have selected the desired crossover frequency, press SELECT to exit this menu and return to the

Speaker Config menu. The selected frequency is common to all speakers defined as ‘SMALL’. Only one

global crossover value is available.

NOTE 1: The crossover action is onl y applied to speakers defined as ‘SMALL’ in the speaker configuration menu.

NOTE 2:If NONE is selected for the crossover frequency, the LFE signal (Low Frequency Effects channel)

will be presented with no cut-off frequency. LFE signals can be up to 120 Hz in bandwidth,
which replicates the studio mix.

Setting the Channel Delays

In this step you will need to measure within one foot the distances from your chosen listening/viewing position

to the various loudspeaker locations in your system. You will need the tape measure or other means of making

these measurements. You should record this data for future reference.

1. Now, make a measurement from the chosen seated position to each loudspeaker.

2. Next, enter the main menu by pressing on one of the menu buttons on the SP1.7 front panel. Move the cursor

to “DLY”. Hit ‘Select’ - You are now in the Delay Menu. The SP1.7 automatically calculates the required

delay time per speaker using the data entered as distance from the listening position. Delays are implemented

using DSP RAM and have a maximum value.

IMPORTANT: It is recommended that the closest speaker is entered first. The SP1.7 will calculate the

maximum allowable distance from the listening position for the remaining speakers. Please note that delay is

represented in feet. For reference, One foot (0.3048 meters) = approximately 1 millisecond of delay.

22

Figure 17: Change the Crossover Frequency

Figure 18: Delays Menu

23

3. Move the cursor to the speaker you want to set the distance/delay for (L C R RS LS RB LB SB). Hit Select.

Now you can adjust the Delay value which is equivalent to the distance you measured for the selected speaker

using the arrow buttons. Set the delay for each speaker in your system to the nearest foot/meter. Rounding up

is OK. Remember that if one back speaker is selected, the Left Back output is used to set the delay.

4. Hit SELECT or [X] Exit when finished.

The SP1.7’s default factory settings as shipped are 10 feet to every speaker, resulting in zero overall delay.

Calibrating and Setting Levels/Channel to Channel Balance.

1. Position the Sound Level Meter at the Centre point of your listening area, at average ear height [approximately

40 - 46 inches {102 - 117 cm.} with its microphone positioned vertically (pointing at the ceiling). DO NOT

aim the sensing microphone at the speakers, as this will produce inaccurate level indications.

2. Using the SP1.7 Remote, press and hold for approximately 3-5 seconds the key labeled “TEST”.

IMPORTANT: The Test-Noise Mode can only be initiated from the SP1.7 remote, and not from the front panel.

The shaped pink-noise test signal will begin with the left-front loudspeaker. If the signal does not appear in

this speaker please stop the process and check your wiring and connections for proper configuration.

IMPORTANT: When using the Pink Noise generator within the SP1.7 for speaker level calibration, the

salient point is that all channels measure equal dB. After pushing the test button, the pink noise will start in

the front left speaker. Record the dB level from this speaker (with the level trim value at 0 dB on the LCD

Display), and adjust all the others to match it. It is not critical to reach some specific dB level (ex. 85 dB), it

is more important that all channels are at equal levels.

3. Hit the “TEST” button again to sequence the noise to the next speaker.

The sequence is L -> C -> R -> RS -> RB -> LB -> LS -> SUB -> EXIT.

4. Using the volume up/down arrows on the remote or the arrow keys on the SP1.7 adjust the level of the noise

for each speaker so that it matches the front left channel noise (dB) level on the Sound Level Meter.

5. When the cycle is complete, the test noise signal will end, and the unit will switch back to the previous mode.

If any output is unused (as defined by ‘NONE’ in the Speaker Configuration Setup), the noise sequence will

automatically skip to the next speaker in the sequence.

Setting Channel Levels without Pink Noise

If you wish to adjust the speaker level trims without using the pink-noise test signal, this can be done from the

Front Panel menu system.

1.`First enter the main menu by pressing on any one of the menu buttons on the SP1.7 front panel (< - > or

SELECT).

2. Next move the cursor to “LVL”. Hit ‘SELECT’ - You are now in the Level Trim Menu.

3. Move the cursor to the speaker(s) you want to change the level for using the arrow keys (L, C, R, RS, LS,

RB, LB, SUB). Hit ‘SELECT’. Now you can adjust the Level for the selected speaker using the arrow buttons.

4. Hit ‘SELECT’ when finished, and repeat Step 3 to change the Level Trim for any of the other speakers.

Setting the THX Subwoofer Limiter or “Bass Peak Level Manager”

To diminish the chance that your subwoofer will overload from the large amount of bass, often present in the

LFE channel the system uses a Peak Management circuit which works with the data you supplied during speaker

setup to help match the subwoofer output to your specific subwoofer’s capabilities. Please note that the factory

default for the BLPM is -14 dB since the capabilities of your specific subwoofer are unknown. In the SP1.7

setup and calibration section above, the final step you should have performed was to set the BLPM for your sub-

woofer’s specific capabilities.

Setting the BPLM with Pink Noise

1. Enter the main menu by pressing on one of the menu buttons. Move the cursor to “OS”. Hit ‘Select’ - You

are now in the Other Settings (Optical/THX) Menu.

2. Move the cursor to ‘BPLM’. Hit Select. [BPLM=Bass Peak level Manager]

You will see the following screen.

24

Figure 19: Highlight “BPLM”
in the Other Setting Menu

Figure 20: BPLM Routine Choice

25

3. Hit ‘SELECT’ and you will see the adjustment screen picture below appear, and you will hear a low level

Pink Noise signal coming from your subwoofer and/or large speakers.

Now you can adjust the value of the subwoofer limiter (-24 to 0 dB). Slowly increase the level by pressing the

“>” button (display counting up from -24) until you hear overload/ distortion/bottoming/popping from your sub-

woofer(s). When you do, reduce the value shown by 1dB and Hit ‘SELECT’ to save the setting. You can always

return to this menu to make further adjustments if needed.

Setting the BPLM without Pink Noise

To adjust the BPLM setting without running the Noise routine, Enter the BPLM as above, but when the SP1

prompts “Do BPLM Routine?”, use the arrow keys to select ‘NO’ and hit ‘SELECT’. This will bring up the

numeric value of the BPLM setting without the noise signal. You can now adjust the value using the arrow keys,

and hit ‘SELECT’ when finished.

Caution: If the BPLM is set to “OFF” or “0”, the Bass Limiting function is disabled. In this case, you may run

the risk of speaker damage due to bass overload. Please be sure that your speaker system can handle high bass

levels before disabling the BPLM.

Enabling DTS-ES 6.1 Decoding

DTS-ES Discrete 6.1 will only operate on DTS source bitstreams that have a discrete sixth channel encoded. If

the Back Speakers are turned on via the speaker config menu (See Speaker config on page 19.), and the input

bitstream permits, DTS-ES Discrete 6.1 will be detected and enabled automatically.

DTS-ES Matrix 6.1 processing creates back channel material from material contained in the surround channels of

DTS 5.1 bitstreams. Some DTS material has been formatted so that when DTS-ES Matrix 6.1 processing is applied,

specific material will be placed on the back channels, while other specific material remains on the surround channels.

To control when DTS-ES Matrix 6.1 processing will be applied, change the ES Control setting as follows:

1. First enter the main menu by pressing on any one of the menu buttons (< - > or SELECT)

Figure 21: BPLM Routine for level setting

Figure 22: Highlight “OS” in Setup Menu

2. Next move the cursor to “OS”. Hit ‘SELECT’ – you are now in the ‘Other Settings’ menu.

3. Move the cursor to “ES”. Hit ‘SELECT’ – you can now change the ES Control setting.

The options available in this menu are:

DISABLE – DTS-ES will not be decoded
ON – DTS-ES Matrix will be forced on for all DTS 5.1 channel input bitstreams, if the back channels are enabled.
AUTO – DTS-ES Matrix will be decode if the incoming DTS bitstream is flagged as having DTS-ES encoded

content, and if the back channels are enabled.

Enabling THX Surround EX™ Decoding

THX Surround EX™ processing creates back channel material from material contained in the surround channels

of Dolby Digital 5.1 bitstreams. Some Dolby Digital material has been formatted so that THX Surround EX™

processing is applied, specific material will be placed on the back channels, while other specific material remains

on the surround channels. To control when THX Surround EX™ processing will be applied, change the EX

Control setting as follows:

1. First enter the main menu by pressing on any one of the menu buttons (< - > or SELECT)

2. Next move the cursor to “OS”. Hit ‘SELECT’ – you are now in the ‘Other Settings’ menu.

Changing Dolby PLII Music Settings

Dolby Pro Logic II is the next generation in Dolby Surround decoding. It is designed specifically to decode all

existing Dolby Surround programs and provide improved spatiality and directionality of sounds. Through the use

of an elegant new approach to matrix surround decoding and the decoding of stereo, full-bandwidth surround

outputs, Pro Logic II decoding effectively bridges the gap between Pro Logic and discrete Dolby Digital 5.1

soundtracks.

Pro Logic II is also designed for use with unencoded stereo music recordings. The listener is drawn into a three-

dimensional space, rather than hearing a flat, two-dimensional presentation. This not only helps develop a more

involving soundfield, but also solves the narrow “sweet spot” problem of conventional stereo reproduction. All

of these benefits are provided using the same “3/2” speaker configuration consumers have been using with Pro

Logic since 1988.

Pro Logic II follows in the footsteps of Pro Logic and Dolby Digital 5.1-channel decoding. In many key

respects, Pro Logic II fits into this environment seamlessly. Electrically, the parameters of headroom, reference

level, channel calibration, output trim controls, noise sequencer, and master volume control are all unchanged rel-

ative to a Pro Logic decoder within a 5.1-channel Dolby Digital decoder. The main difference is that besides the

stereo surround outputs, Pro Logic II provides some new, optional modes to enhance music playback.

Figure 27: Change “EX” Control Setting

PLII Film 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 autobalance is operational.

PLII Music This mode can enhance normal stereo music recordings, offering a wider soundstage and

enhanced spatial effects. This offers user control over the 1. Center Width, 2. Dimension and

3. Panorama. PLII Music also applies a mild high-frequency shelf filter to the surround channels

for a more natural soundfield. Autobalance is disabled.

1. Dimension Control. Allows the user to gradually adjust the soundfield either towards the front or towards the

rear. This can be useful to help achieve a more suitable balance from all the speakers with certain recordings.

2. Center Width Control. Allows variable adjustment of the center image so it may be heard only from the center

speaker, only from the left/right speakers as a “phantom” center image, or various combinations of all three

front speakers. For home users, it allows improved blending of the center and main speakers, or to control

the sense of image width, or “weight.”

3. Panorama Mode. Extends the front stereo image to include the surround speakers for an exciting “wrap

around” effect with side wall imaging.

To change the PLII Music settings:

1. First enter the main menu by pressing on any one of the menu buttons (< - > or SELECT)

2. Next move the cursor to “PLII”. Hit ‘SELECT’ – you are now in the ‘PLII Music’ menu.

28

3. Move the cursor to the setting you want to change. The options are:

CEN – center width (0 to 7; default 3)

DIM – dimension (-3 to +3; default 0)

PAN – panorama (YES or NO; default NO)

Hit ‘SELECT’ – you can now change the chosen PLII setting.

Changing DTS NEO:6 Settings

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.)

Neo:6 also offers a music mode to expand 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.

“Center Image” is a variable in Neo:6 music mode only.

Neo:6 derives a center channel from two-channel material. In cinema mode, for Left/Right film soundtracks,

sounds steered to the center are subtracted from the left and right channels. 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 center

channel, while preserving the original perspective of the stereo mix. Therefore the derived center is never fully

subtracted from the left and right channels.

“Center Image” is the factor controlling the amount of subtraction. It varies between 0 and 0.5 in steps of 0.1

and the default value is 0.2.

When Center Image = 0, the factor is zero and nothing is subtracted from the left and right channels. When

Center Image = 0.5, the center channel is subtracted from the left and right channels at half level (-6 dB) for

each channel. The signal level sent to the center channel output is not affected by Center Image.

This control should be set based on room layout and personal preferences. A setting of 0 allows the left and

right channels to pass through unaltered from the stereo mix. A setting of 0.5 gives more center channel domi-

nance, which is particularly desirable if listeners are located well off-center. At any setting, the center speaker

anchors the image.

29

Figure 30: Change the PLII Centre Width Setting

To change the Center Image:

1. First enter the main menu by pressing on any one of the menu buttons (< - > or SELECT)

2. Next move the cursor to “DTS”. Hit ‘SELECT’ – you are now in the ‘DTS Settings’ menu.

3. Move the cursor to ‘CEN’ Hit ‘SELECT’ – you can now change the NEO:6 center imgage setting. (0 – 0.5)

APPENDIX A - SP1.7 Surround MODES

Pressing the MODE button will illuminate the LED and let you sequentially select one of the many available

decoding modes for 2 channel signals. These special modes are designed to expand your enjoyment of almost

any 2 channel music source and many other 2 channel signals. You are encouraged to experiment with the

options on various sources. Not all will supply something you may like, but there are so many variables that it

does pay to take a few moments to listen to the options. The custom SP1.7 Surround Modes use a set of DSP

algorithms to create a set of simulated signals using the original left and right 2 channel data and feeds these to

the to centre and surround speakers.

Surround Modes

Hall. This Sound Field Mode emulates a medium or large concert hall. It provides a longer reverberation time

than other modes and gives the effect that music is heard at a greater distance from the performers. It is ideal for

orchestral classical music and light orchestral music, such as that found on many film soundtrack albums, but

this mode will generally sound a bit muddy on rock or pop music.

Theatre. This Sound Field Mode simulates a room larger than a club, and it is intended to simulate what you

would hear in the front rows in a medium-size theatre. The reverberation here is not overly obtrusive, since a

theatre is intended for clarity of speech. This mode is suited for opera, rock, easy listening music, and any music

you might hear in a theatre.

Stadium. This Sound Field Mode provides a prominent “slap echo,” emanating largely from the rear, and it

gives a lively effect especially on solo instruments such as bass guitar. This mode is unsuitable for speech as the

echo destroys intelligibility. The sound is “big” but slightly artificial — it is suitable for stadium rock, and other

music that one would hear in a large stadium environment.

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.

Church. This Sound Field Mode simulates a large, spacious acoustic space with a very long reverberation time.

It is well-suited to organ music, choral music, and New Age music. It is too reverberant for most other kinds of

material, but it is very spacious for material it is suited to.

Natural. This 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.

Party. The Party (Five-Channel Mono) Mode converts stereo input to a mono signal which is then distributed

to the five satellite channels.

Stereo5. The Stereo5 (Five-Channel Stereo) Mode converts stereo input to surround sound. The stereo signal

is distributed to the five satellite channels, creating a giant stereo image in your listening space.

(Please note that the apparent effect of the Surround Mode can be adjusted by altering the delay parameters and

channel volume of the centre, surrounds and back channel(s), using the appropriate menus).

NOTE: These music modes do NOT utilized the back surround speakers.

Remember there really are no “correct” settings that will work equally well for all kinds of music. You may need

to adjust the parameters and mode depending on the music material.

APPENDIX B - THX INFORMATION

Below is a summary of issues and information related to the proprietary and patented THX processing incorpo-

rated used in the SP1. The available space cannot include all the available information on this topic. Therefore,

if you want more information or wish to research the topic in more detail please use the THX website at

WWW.THX.COM.

When you choose the THX option for surround decoding modes within the SP1.7, by pressing the THX button

on the front panel or the remote, an additional “post-processing” method is activated. The additional signal pro-

cessing used in this mode is the result of extensive research, testing and refinement by the technical and engi-

neering staff at LucasFilm, Ltd. All movie soundtracks regardless of their original encoding format (Dolby

Digital, Dolby Pro-Logic, DTS, Stereo or Mono) can benefit from THX post-processing.

NOTE:THX is only available with movie modes PLII Film, NEO:6 Cinema, Pro Logic, Dolby Digital, and
DTS as per THX licensing agreements.

The THX mode would not normally be activated for music or movies that were made specifically for television

or other broadcast shows such as sports programming. The THX processing, designed to compensate for large

room mixing environments is not required for these programs because they are normally mixed/post-produced in

small room environments, as opposed to the large room environments normally used for theatrical motion pic-

ture mixing/post-production.

The SP1’s THX mode adds additional DSP post-processing to either the Dolby or DTS processing already in

place to help create a more precise match between the sound produced within a commercial motion picture the-

ater and the sound produced in your residential ‘theater’.

THX’s research shows that this is necessary because, all of the multi-channel film sound formats were originally

designed and spectrally balanced for use within large commercial movie theaters. Moreover, the specially

equipped and designed theater used by the sound mixing professionals to produce the final theatrical audio track

on any film (called a ‘dubbing stage’) is also considerably larger than your ‘home theater’ since it was created to

replicate the environment of a typical commercial cinema space, not your home theater space.

It is in those “dubbing stages” that the dialogue, sound effects and music are all individually recorded and

mixed to a six (5.1) or four channel(Pro- Logic) soundtrack for release in commercial movie theaters. This is the

same soundtrack that is later released on videotape and DVD for playback in a Home Theatre system.

During their research, the THX engineers identified the fundamental tonal and spatial errors created when

Theatre environment film sound tracks are reproduced in residential spaces.

The SP1.7, contains special processing designed by THX to correct those errors and restore the appropriate tonal

and spatial balance to a movie soundtrack, so that you can hear what the film’s producer/director intended.
