Shipping Box and Packing Material

Please keep the original shipping box and all packing material. In the unlikely event you have a problem and must return it for service, you must use the proper packing material as the unit is not insurable by carriers otherwise. Replacement packing materials consisting of a shipping carton with plastic foam inserts is available from Bryston for a small fee.
Prepare your installation site by following the steps
below: Consult page “Rear Panel” on page 4
for rear panel diagram indicating location of key connections.
1. For non North American models that are delivered with a fuse attached to the AC cord, install the fuse before plugging the unit into mains power.
2. Ensure your electrical circuit has a good ground connection with all audio equipment connected to the same ground node to avoid noise or hum due to a ground loop.
3. Prepare attached equipment such as display or projector, audio ampliers, speakers, network
switch and associated cables.
4. Network should be running a DHCP server to enable the SP4 to obtain an IP address.

Ventilation

The SP4 is a cool-running line level component. It
generates far less heat than ampliers and many
other components. It can be safely placed inside furniture or an equipment rack. However, it should
not be tightly enclosed. Some airow is desired.
Note that the rear panel fan needs to be able to circulate air especially when the SP4 is under heavy load.

Connecting to A/C Power

If necessary, install the included fuse into the fuse
socket. Plug the IEC-320 C14 end of the power
cord into the SP4, then plug the other end into an approved and grounded A/C receptacle.

Connecting to Network

Using at CAT5e or better cable, connect the SP4 to your local area network. See “Get Network Access” on page 7 to identify IP address.

Connect IR Interface (Optional)

Should you choose to use an IR interface, you will need to connect an IR receiver to the IR Input of the SP4.

SP4 Immersive Surround Processor

Connect Source Components

Legacy digital sources can be connected to the
digital inputs 1-6. Stereo or surround analog sources can be connected to the Analog Inputs section.
Analog input conguration is dened at “4. Audio In”
on page 12. HDMI sources can be connected as well. Note that though all inputs support HDCP2.2, inputs 1-4 only support HDMI 1.4 speeds by default. Inupts 5-7 support HDMI 2.0 speeds.

Connect to Display

Connect your displays using HDMI output. Note that outputs are parallel (same content) but HDMI OUT 1 supports up to HDCP 1.4 while HDMI OUT 2 supports HDCP 2.2. Should no picture appear on
HDMI OUT 1, troubleshoot EDID conicts.

Connect Audio Outputs

If you choose to connect your outputs at this step, take note of which output number is routed to each channel so that you can map them appropriately in a later step. Otherwise, when you setup the theater using the web UI, the default outputs will be noted for you. At that point, you can connect your
ampliers based on the default output channel
mapping.
First Run
Upon rst run, you must congure the SP4 according to your specications using the web
based user interface. There is no on-screen display
or provision to congure the unit using the front
panel.

Input Settings

The SP4 permits the installer to create access to sources in a very intuitive way for the end user. The installer is advised to title inputs thoughtfully and without ambiguity. No longer must an end user remember which physical input is attached to a particular source component. Further, only inputs
specically congured as ACTIVE will be available
from the remote control. Finally, multiple inputs can be created from a single source component for the purposes of loading separate settings. For example, you may have an input titled ‘CD Music’ that accesses a Blu-Ray player attached to HDMI 7 that by default downmixes everything to stereo and another input titled ‘Blu-Ray Movie’ that accesses the same source component but upmixes all audio to Dolby Surround.
may type in this box and change the name to something more intuitive. Supports a maximum of 10 characters.
3. Video In
For any given input, you can map separate video and audio inputs except that when the audio input is an HDMI input, the video input must be the same HDMI input. None may also be chosen when no video is desired.
4. Audio In
For any given input, you can map separate video and audio inputs except that when the audio input is an HDMI input, video must be the same HDMI input. None may also be chosen when no video is desired. Note that the analog input matrix may be selected as a particular stereo pair or as a 7.1 input.
1. Active
Any input with a blue Y is accessible from remote controls. To disable access to an input, click the Y and it will change to an N and gray out the entire row thereby disabling access to this input. You are advised to disable any input with no source component attached.
2. Input
This is the name of the input that will appear in remote control applications. By default, the name is the same as the default audio input. You
5. Preferred Upmix
On a per input level, you may choose to engage a particular upmixer, or leave the option set to none. This setting overrides any preferred upmix
dened as part of a preset. So, if a preset is to
be used in conjunction with this input, and that preset includes specifying an upmix, leave this setting to None.
6. Trimmer
Each input may have the audio attenuated by a
7
6
12
Page 13
SP4 Immersive Surround Processor
specic value in an eort to level match source
components and yield an expected volume level in the room regardless of source selected. No gain can be applied, only attenuation. The range
is -30dB to 0dB with 0.1dB precision. The + and -
buttons adjust the value by 0.5dB.
7. AV Delay
Each input may have a synchronization delay set between video and audio. This range is 0-100ms in 1ms increments.
8. Triggers
The SP4 can trigger connected devices on using the 4 DC trigger output jacks on the back when
a specic input is selected. Most commonly,
this is used to power on the source component
connected to a specic input. To enable this
feature, the desired trigger must be set to Auto
Switching: Enabled on Input in the Settings
menu. See “Triggers” on page 26. To engage a trigger based on input, click the gray N. It will turn into a blue Y when the trigger will be activated upon selection of that input.
Note that aer making any changes, you
must press the SAVE button near the top right of the screen or you will loose your changes.

Building a Theater - Defining Channels
To assign analog outputs to particular channels, you must build a theater. A theater may occupy as few as 2 channels or as many as 16. There are over
70 options for theaters. Any channels le over may
be assigned to secondary multi-channel theaters, 2 channel A/V zones, audio only zones, mono zones or if SphereAudio is installed, headphone zones. A physical output can only be assigned to one theater or zone.
To assign channel outputs, you must rst build
a Theater or Zone. Theaters are multi-channel systems. Zones are either 1 or 2 channel audio or audio/video zones. Any theaters or zones created appear to the right and are listed by their names which you assign. By default, the
SP4 ships with a 2 channel theater congured.
To build your own, delete this theater and
create a new one. Click EDIT, then DELETE.
Click OK to conrm. You will be returned to the Main
Speakers page.
1. Create Theater
Click Create Theater to build your new theater. Theater 1 will appear to the right of the Create
Theater button. Click Congure to proceed.
2. Select Speaker Layout
All possible loudspeaker layouts based on available channel count are listed. A shorter list “Recommended by Bryston” is listed by default and contains most commonly used options. Click All to see all possible options.
Denitions are titled by channel count in the following order. Base Layer . LFE . Height Layer . Top Layer. For example, 9.1.0.6 would feature
9 ear level speakers, 1 sub channel, 0 height
speakers (common only for Auro3D layouts),
and 6 ceiling speakers.
For each denition, you can use the
matrix to see how compatible that layout
is with each of the 3 codecs and which
possible speaker locations are occupied. To reduce ambiguity, you can also click VIEW to see the layout visualized in a room.

Ways per Speaker (LCR): For the front le, center, and right speakers, you can dene multi-way active loudspeakers up to 3 ways per speaker.
Surround Layers: Optionally duplicate surround channels to increase coverage in large rooms to match seating row count.
Subwoofers: Though there is only 1 LFE channel, you can specify the number of channels which will drive discrete subwoofers. Unlike daisy chaining subwoofers, each channel can have its own settings and EQ.
Enabled Mode Layers: When using customized
Dolby Atmos up-ring loudspeakers in place of ceiling
mounted top layer speakers, choose whether these speakers are mounted on top of the Front or Side loudspeakers.
Custom Channel Duplicator: Check this box and enter the number of duplicates for any channel in the theater.

Test Tone Generator

The SP4 includes a highly congurable test tone
generator which can be used to help manually calibrate channels.
1. Generator
Click this button to turn on the tone generator. It will automatically start with Group 1. The channels outputting sound will be highlighted in green.
Choose the type of noise or tone created by the generator.
Sine: Generates a sine wave at the frequency
specied.
Pink Noise: Generates full bandwidth pink noise
Pink Noise 400-4kHz: Generates pink noise band
limited to one decade. This is particularly useful when setting relative levels between channels with
dramatically dierent useful bandwidths. Remember SPL meters measure not only sound pressure but also
bandwidth.
16
2. Setup
Unlike traditional generators, the SP4 will not strictly play tones one channel at a time. Click Setup to assign channels to groups. Each group may contain one or more channels. For example, if you have 2-way active loudspeakers, you may wish to group the high frequency and low frequency component of each into one group.
3. Noise Selection
4. Gain
The gain gure can be set so that the noise
generator operates at a level at or below that of a normal source playing at 0dBFS. Default is 0.1 (-20dBFS).
5. Group
When the noise generator is active, use this
function to play the noise through dierent groups dened in “2. Setup”.
6. RTA
When a USB microphone (such as the optional Theater Acoustic Diagnostic Kit) is connected to the SP4, you can use the Real Time Analyzer to visualize the response of loudspeaker groups in the room. Note that the built in RTA is not accurate enough to use for calibration, but is useful for getting a good idea of the
16
Page 17
SP4 Immersive Surround Processor
approximate response of the system. Maximum level of the capture can be set by adjusting
Mic Ref Level. Graph vertical scale can be changed from Logrithmic (default) to Linear.
7. Dirac
See “Dirac Live” on page 23 for use of optional Dirac Live Calibration Tool.
8. Volume Reference
It is good practice when calibrating systems to always work at a reference level such as 85dB C-weighted. Before activating the noise generator, make sure the master volume is at a low level. Set and recall a reference master volume value. Click SET once you have dialed
the value you’d like to store. Click RECALL to
quickly return to that value.

Individual Channel Adjustments

Once your theater is dened, each channel can be individually ne tuned. The theater can also be
renamed, and a child theater can be created which
enables stereo le, right, or mono audio to be
routed to existing channel assignments.
11. Signal
Indicates which signal is routed to this output. Should you desire to remap signal routing, you can do so with Output Mapping. See “Output Mapping” on page 19 for details.
12. Channel Name
Customizable name to easily identify each channel. By default, these are named for the signal sent to each channel. You may decide to change these to speaker model or another
unique identier. Maximum allowable character
count is 25.
13. Size / Filter
Identify each channel as either Large, Small, or Large and Sub. When a channel is set to Large, no bass is redirected from this channel
to the subwoofer. Use this setting when the
loudspeaker has suicient bandwidth and output capability to reproduce suicient
bass. When a channel is set to Small, bass in this channel is redirected to the subwoofers according to the Frequency and Slope for that
channel. Large and Sub is a special case that
not only allows that channel to reproduce full bandwidth audio, but also duplicates bass in that channel to the subwoofer(s) according to the Frequency and Slope for that channel.
9. Channel Status
Each channel is enabled by default. If for some reason this channel needs to be disabled, click the ON button. It will turn to OFF and audio will no longer be routed to that channel. Note that audio will not be re-routed to other channels. Channel status is set per Theater / Zone and is
not stored as part of a prole.
10. EQ
Each channel can have up to 10 channels of
parametric EQ congured. See “Channel EQ” on
page 20 for detailed EQ options. EQ settings
are stored as part of proles.
Subwoofer channels have specic settings. By denition, subwoofers have limited bandwidth
and some are more limited than others.
Low Pass LFE: When this is set to ON, the subwoofer
channel has a low pass lter applied according to
that channel’s Frequency and Slope. This is designed to limit the channel’s ability to reproduce the upper portion of the bass spectrum. This is usually done to prevent the subwoofer from contributing midrange distortion.
Subsonic SUB: When this is set to ON, a high pass
lter is applied to the channel which restricts the
subwoofer’s ability to reproduce very deep bass
according to the frequency and slope dened for
that channel. Many subwoofers, especially smaller
models do not have the amplier power or driver
17
Page 18
17

21
displacement required to accurately reproduce very
deep bass. By actively ltering very deep bass away
from the subwoofer, it is better able to reproduce bass within it’s useful bandwidth.
* Items 14 and 15 pertain to Standard Bass Management Mode in which the crossover point
and slope dened apply to both the high pass and low pass sides of the lter equally. For Expert Bass
Management, see “Expert Bass Management” on page 19.
14. Frequency
When the channel is set to Small or Large and Sub, the Frequency denes the point below
which bass in this channel is routed to the subwoofer(s). Note that the frequency is the
-3dB point along the slope dened in the next
column and is not an absolute cuto point.
15. Slope
The rate at which bass is ‘crossed over’ into the subwoofer when the channel is set to Small or
Large and Sub. LR 12dB and LR 24dB are 2nd order and 4th order Linkwitz Riley alignments
respectively.
16. With LFE
When a channel is set to Large or Large and Sub, this channel can optionally reproduce LFE bass
which would normally be the sole responsibility of the subwoofer channels. When set to None,
no LFE will be mixed into this channel. When set to a gure between 0dB and -20dB, LFE bass attenuated by that gure will be mixed into
this channel. This feature is useful when the
main channels have suicient bandwidth AND
dynamic range to support the subwoofers in creating an appropriate amount of bass sound pressure in the room.
Items 16-21 apply to settings found in the ‘Delay,
Level, Limiter, and Phase’ section.
17. Delay units
Choose whether to measure channel delays in meters (default), feet, or milliseconds.
18. Delay per Channel
Each channel should have distance/delay set beteween that loudspeaker and the sweetspot.
You can dene this in meters (default), feet, or
ms depending on your setting in 16.
19. Level
Set the level of each channel in between -100dB
and +12dB in 0.1dB increments. Best practice is to set other channels to a negative gure relative
to the loudest channel to avoid clipping when possible. Global gain makeup can be applied to the theater when the relative level of the theater is too low (usually a result of a high degree
of correction due to Dirac Live’s mixed phase
18
Page 19
SP4 Immersive Surround Processor
lters). Use global gain makeup judiciously to
avoid clipping.
20. Limiter
To prevent distortion due to loudspeaker
overdriving or amplier clipping, you may wish
to engage a limiter on a channel. When enabled, a compressor will attenuate audio above the
threshold set by the Limiter Value for that
channel back down to that value. For instance,
if the limiter is enabled and set to -3dBFS, any audio that exceeds -3dBFS will be reproduced at -3dBFS. By their nature, limiters are not ideal
acoustic solutions, but this feature can prevent subjectively worse sounding distortion, or in extreme cases, damage to loudspeakers or
ampliers. If you nd that you are aggressively
using the limiter function, you are encouraged
to upgrade loudspeakers and/or amplication.
21. Phase Invert
Check the box for any channel you in which you wish to invert polarity.

Expert Bass Management

When it is desirable to ne tune subwoofer
integration beyond what is possible in Standard Bass Management Mode, you may select Expert.
The exibility within can achieve greater subwoofer
integration, but should only be used by calibrators
with suicient skill otherwise comparably poor
results may be inevitable. Compared to Standard
mode, Expert includes the following features:
Additional Size/Filter options
1. Size/Filter
Speakers may be set to one of the following 4
options:
Small: Channel is high pass ltered according to the
HPF frequency and slope. Bass is routed to subwoofer
channels according to frequency and slope dened by LPF frequency and slope. Small speakers cannot have subwoofer or LFE bass mixed in.
Large: Channel is not band limited. Channel can
have subwoofer and/or LFE bass mixed in.
Large and Sub: Channel is not band limited, but a
copy of bass for this channel is routed to subwoofer channels as well. Set the frequency below which bass should be sent to the subwoofer and the slope at which the crossover occurs.
Large with Sub: This special case enables you to
eectively split a full range loudspeaker into a “small
speaker” plus “virtual subwoofer”. The HPF frequency
and slope dene the characteristic of the “small speaker” portion. LPF frequency and slope dene the
virtual subwoofer characteristic.

Output Mapping

Should you wish to map a physical analog output channel to a loudspeaker other than the default assignment, you may do so from the Main Speakers page. Click Output Mapping.
Ability to separate HPF and LPF frequency and slope per channel
Ability to mix SUB bass (not just LFE bass) back into
channels set to Large, Large and Sub and Large with
Sub.
Using the New Output column on the right of the pop-up menu, select a new output channel. If you choose a currently occupied new output channel, that channel will be automatically reassigned. Save.

Multi-way Loudspeaker Setup

During the initial Theater Denition setup, you have the option of dening the front LCR speakers as multi-way. Doing so will assign 2 or 3 output
channels to each speaker instead of 1. In this
conguration, more than 1 amplier will be used
per loudspeaker, and the SP4 will perform the crossover function for each loudspeaker.
All settings in the Bass Management section detailed in “Individual Channel Adjustments” on page 17 and “Expert Bass Management” on page 19 also apply and will not be covered again here.
This section only describes the dierences notable for multi-way loudspeaker conguration.
1. Signal
Note that in this example (Le Front is a 3-way active loudspeaker), Each of the rst 3 channels receives the same Le Front signal.
2. Channel Name
By default, the channel names are named by the signal they receive and proceeded by a sequential number. For clarity, you may wish to rename these according to the signal they
reproduce e.g. Le Front High, Le Front Mid, Le Front Low.
5
Full Range, Low Pass Filtered, Middle (band pass), or
High Pass Filtered audio. Two-way speakers will not have Middle option.
Crossover Frequency: When the section is chosen
as anything other than Full Range, set the crossover
frequency for the Low and High Pass lters for each
section.
Slope: For each lter, select a slope. Options are
Butterworth 6dB / oct, Butterworth 12dB / oct,
Butterworth 18dB / oct, Linkwitz Riley 12dB / oct, and Linkwitz Riley 24dB oct.
4. Delay
Set the delay of each section. For active multi­way loudspeakers, it may be helpful to do this in milliseconds and measure time-of-arrival
dierences at the crossover point when using LR or BT6 lters to time align each section of a
multi-way loudspeaker.
5. Level
Active multi-way loudspeakers almost certainly
have dierent sensitivities per module. Set the
relative level of each here. When possible, use
0 as the maximum gure and attenuate other
channels to match the loudest channel. You can also set global makeup gain for the entire
theater as described in “19. Level” on page 18.

Channel EQ

3. Multi-way Management
Use this section to lter the signal for each
section.
Section: Choose whether each channel reproduces
20
Each channel can have up to 10 bands of parametric EQ applied manually. To design EQ curves for any channel, click the EQ button under the Status
column for that channel. Remember to SAVE oen!

1. EQ Bypass
When developing a custom set of EQ per channel, it is sometimes helpful to bypass the entire group of EQ to check your progress against the starting point.
2. Filter Shape
Each lter must begin with a variation of one of
5 types.
Low Pass: Continuously declining output above a
cuto frequency at a dened rate.
High Pass: Continuously declining output below a cuto frequency at a dened rate.
Bell: Band pass or cut lter with a dened center frequency, boost or cut amount, and Q.
Low Shelf: Boost or cut frequencies below a cuto
frequency by a xed amount.
High Shelf: Boost or cut frequencies above a cuto frequency by a xed amount.
For LPF, HPF, and Bell lters, choose
Butterworth 12dB/oct, Butterworth 12dB/oct
inverse, Linkwitz Riley 12dB/oct, Linkwitz Riley
12dB/oct inverse, Butterworth 24dB/oct, or
Linkwitz Riley 24dB/oct.
3. Frequency
Each lter requires that a center or cuto frequency be specied. You can enter this
number directly in the text box or increment/ decrement by the amount chosen in the header
row using the +/- buttons to the right. Or, you
can use the slider.
4. Gain
Bell and shelving lters require that you set
the amount of boost or cut. You can enter this number directly in the text box or increment/ decrement by the amount chosen in the header
row using the +/- buttons to the right. Or, you
can use the slider.
5. Quality Factor / Bandwidth
Bell lters require that you specify a Q. High Q aects a narrow bandwidth, and low Q aects
a wide bandwidth. You can enter this number directly in the text box or increment/decrement by the amount chosen in the header row using
the +/- buttons to the right. Or, click a fractional
or multiple octave button to automatically calculate Q.
6. Bypass / Reset
In the course of designing your lter, you may
wish to measure or listen to progress compared
to the absence of that lter. Click Bypass to temporarily omit that lter from the aggregate curve. Click Reset to reset that lter back to 0.
7. Copy to Channel
You may wish to duplicate your lter set to
another channel without manually rebuilding it for each identical channel. Select a channel to
copy the current lters to and click COPY.
8. Channel Select
Select the desired channel to equalize here.

Child Theater / Sub Theater

You may optionally create alternate speaker
denitions in your theater with some restrictions.
For example, if you wish to have music playing before the movie plays before everyone is seated and quiet, you might only want that music playing from the overhead speakers so as not to interfere
with conversation. In this case, you can dene a child theater so that stereo le/right audio is played
only through the top speakers (as in the example above).
Child theaters behave just like zones or main theaters in that they can be selected as outputs, programmed into presets and can have multiple
proles.
Note that though multiple Child theaters can be designed per main theater, signal assignment is common to all.
3. Keep Dirac Prole
If you have created a Dirac prole for the parent
theater, you have the option to retain that calibration for the child theater.
4. Save/Close
Save when done, or Close to cancel.
5. Bass Management / Delay Level Phase
Child theaters have comparably limited options compared to full theaters. If a child theater includes a subwoofer channel, the full range channels are forced to small. In this case, you can adjust the crossover frequency, slope and
subwoofer subsonic lter. If no subwoofer
channel is enabled for the child theater, the main channels are forced to large. No Expert Bass Management is available for Child Theaters.

Zones

1. Create Child
From the Main Speakers page, Edit your theater. Click Create Child. A window will appear with a list of loudspeaker names and their channel ID.
2. Zone Signal
For each loudspeaker, select the signal to be
played. You may choose Stereo Le, Stereo
Right, Mono, or None. Subwoofer channels can play Subwoofer signal or None.
22
Zones are mono or stereo, and with or without video output or can be dedicated to headphone playback when used with an external headphone
amplier like the BHA-1. Stereo Audio/Video and
Headphone Zones include provisions for adjusting lip sync. Audio only zones do not. Zones occupy unused channels and can play concurrently with a theater or without one. Note that system wide, only one input may be selected at once. That is, you
may not have dierent content playing to a zone
Page 23
SP4 Immersive Surround Processor
than what is going to the main theater. Zones have all the same features of a main theater except that channels are always “large”, they cannot include subwoofer channels, and they are limited to mono or stereo. In order to control a zone, it must be included in the preset that is currently selected in the remote control. See “Presets” on page 28 for more details.

Dirac Live

Dirac Live is a highly advanced calibration tool which uses sophisticated mixed-phase lters to compensate for loudspeaker and room deciencies
in order to provide optimal acoustic performance of your theater. Though all SP4s are compatible
with the Dirac Live Calibration Tool, it is an optional purchase. The soware license and calibration kit
are usually purchased by the installer, however, they are available for purchase by the end user as well. If you have not purchased the license and/or calibration kit and would like to do so, please speak with your Bryston dealer or with Bryston directly.
All Theaters, zones, and child theaters can be
calibrated with Dirac Live. Presuming you have a
license and calibration kit, prepare your SP4 for calibration by following the steps below.
of the soware available from Bryston is
compatible.
Install the soware on the laptop you will use to
calibrate the SP4. Enter the e-mail you used to
license the soware and your password. Note
that the laptop will need to be connected to the internet to validate your license.
3. Prepare Calibration Hardware
Although we recommend using the kit we provide which includes the UMIK-1 USB microphone, other hardware may be compatible
with the Dirac Live Calibration Tool. This guide
will only cover our hardware.
Connect the UMIK-1 to your laptop. Note the serial number on the microphone. Navigate to
https://www.minidsp.com/products/acoustic-
measurement/umik-1. Enter the serial number
to obtain your unique calibration les.
4. Choose Theater or Zone to Calibrate
From the Main Speakers (A) menu in the SP4 web UI, EDIT (B) the theater or zone you wish to calibrate.
A

1. Dene Speakers
For each theater or zone you will calibrate
using Dirac Live, ensure that you have correctly dened each speaker’s Size/Filter, Frequency and Slope, multi-way speaker denitions and
other Bass Mangement parameters. (“Individual Channel Adjustments” on page 17)
2. Download and install Dirac Live
Calibration Tool Soware
You can download a Mac or PC version of
the soware at http://support.bryston.com/

Even if you own a Dirac Live license for another
branded product, it will not work for the SP4. Only the StormAudio/Bryston branded version
5. Select Base Prole
Select the prole which will serve as the basis for your Dirac Live calibration from the
dropdown menu.
6. Setup Dirac Groups
It is recommended that if your theater includes multiple subwoofers, manually correct levels, EQ, and delay for each. Then, group all the subwoofer channels together for the purposes
of Dirac Live calibration. Also, manually build
any crossover and EQ settings for active loudspeakers. Group separate elements of a
single active loudspeaker together e.g. Low, Mid, and High components of the LEFT FRONT
should be in a single generator group. Click the SETUP button (C) beside the Dirac button.

A popup describing the process will be shown in the web UI. Verify that you are calibrating the correct theater or zone based on the correct
prole. If not, cancel and return to step 4. Once veried, click Start New Calibration.
8. Return to / Open Dirac Live
Calibration Tool Soware
Open the DLCT soware on your laptop. It will scan the network and automatically nd the
SP4 ready for calibration. If it does not, manually enter the IP address of the SP4. Click Proceed.
9. Congure Microphone
In the Recording Device dropdown menu,
choose the UMIK-1 (A). Load the microphone calibration le (B) downloaded in step “3. Prepare Calibration Hardware” on page 23. Of the two les downloaded, the one marked
“...90degree.txt“ is preferred when placing the microphone in an upward facing direction.
A B C D
It is wise to save the project (C) along each step of the calibration in order to make recovery from interruptions easier. Also, measurements can be
reused in order to regenerate a new lter design
following adjustments to the target curve. Click Proceed.
10. Set Levels
24
A B C D E
Now that the microphone is connected, ensure that the room is quiet. Adjust the input gain (A) so the background does not exceed -24dB in the meters. Set the output volume (B) to a low level (-40dB for example). Start the test
noise by pressing the PLAY button (C) on the rst channel and adjust the volume to reach
Page 25
SP4 Immersive Surround Processor
-12dB in the channel’s meter. For each channel,
activate the test noise and correct the channel volume using the corresponding slider (D) so that the meter reads approximately -12dB. Note that all channels are automatically listed
and subwoofers are automatically identied.
Remember that it is important that multi-way speakers and subwoofers have already been individually aligned and grouped therefore will appear as one loudspeaker. Click Proceed (E).
11. Measure Acoustic Response of Sweet Spot
listening positions. With each measurement, the waveform graphic will update. Click Proceed when done with all 9 measurements.
13. Target Curve
Once all measurements are complete, you can visualize measurements of each speaker. You can customize the target curve for each speaker by (A) limiting the correction window and (B) dragging anchor points on the target curve to desired locations.
A
B
C D
Place the microphone in the exact sweet spot of the room at ear level to begin. It must be in
the le-to-right center of the room since it will
be used for loudspeaker distance and level calculations. Select the type of listening area
you wish to dene. Chair is for a single listening
position, Sofa is a somewhat wider range of listening positions, and Auditorium is the widest. Start the measurement by pressing the START button. The measurement waveform graphic is updated in real time.
12. Measure Acoustic Response of Remaining Positions
Once the rst measurement is taken, that
position will turn green indicating successful capture. Move the microphone to the next position indicated in the diagram. Use the View Menu to rotate the diagram to clearly identify the next position. Repeat measurements for all
Clicking Auto Target (C) will generate a good target response curve that respects the bandwidth of the speaker and does not try to apply too much gain to areas of low output. Good target curve design is beyond the scope of this document, but there are some key points to remember.
Do not attempt to boost bass of a loudspeaker below its low frequency limit as this will only lead to high distortion and likely damage
High quality speakers usually benet from limiting the correction window to low frequencies.
Ideal curves usually have a slightly downward slope.
A loudspeaker may have a at amplitude response on axis, but will rarely be at o axis.
Aim for identical target curves between channel pairs
(such as Front Le and Front Right) to obtain the best
spatial imaging.
Save the Target Curve (D) for use in another channel or for other future use. Repeat for all channels.

Drag and drop the blue project le into the
StormAudio-Processor ‘SP4-host’ slot.
Save the project and click EXIT.
15. Return to SP4 web UI
A popup has been updated to conrm
that you wish to combine the Dirac
Live corrections with the base prole.
16. Return to Speakers Page
Now that you are back at the page where individual speakers can be edited, you will
notice the new Dirac reference prole you
named in the previous step is selected. New columns created indicate the calculated Dirac
Delay and Dirac Level. No changes can be made to this reference prole. Should you wish to make changes, duplicate the prole, make
desired changes to the duplicate, save changes
to the prole and the theater. See “Proles” on
page 15.
Settings Menu
The SP4 includes a variety of system wide settings that are set in this menu that govern behavior of the unit. Ensure these are set as required for easy operation of the SP4 and any attached devices. These are only accessible to those with Installer level access or Expert User if assigned by the Installer.

Triggers

The SP4 has 4 independent DC voltage triggers
which can be congured to modulate the power/
standby status of connected equipment such as
projectors, source components, or ampliers.
You may keep the default name for each trigger, or rename them to something more descriptive. Each
trigger has the following options available:
Manual Switching: Turn on to enable a button on the remote control interfaces that allows a user to toggle the trigger manually.
Auto Switching: Enabled on Wake activates the
Page 27
SP4 Immersive Surround Processor
trigger when the SP4 is powered on from standby. It will not automatically deactivate the trigger when the SP4 is placed into standby. Enabled on Input makes the trigger available in the Input Menu. When set to Y for an input, the trigger activates when that input is selected from a remote interface. See “8.
Triggers” on page 13. Enabled on Preset makes the
trigger available in the Preset menu. When a preset is selected in which a trigger is marked Y, the trigger is activated. Note that Auto Switching trigger behavior will override any Manual Switching behavior.
Disabled on Sleep: Select Y if the trigger should
deactivate when the SP4 is placed into standby.
Active State: Select whether the active state for the
trigger is 12V or 0V.
Delay: You may wish to set a delay of up to 8
seconds. Usually this is done if you are using triggers
to activate ampliers. If all ampliers power on at
once, the inrush current could trip a circuit breaker.
Note that all Bryston ampliers since the SST series feature SoStart circuitry which slowly ramps up power into the amplier. Bryston amplier triggers
may be daisy chained so that only once the preceding
amplier is fully powered does the following amplier
initiate it’s power up sequence thereby obviating the need for a delay (or multiple triggers) when using
modern Bryston ampliers.

Parameters

Downmix zone: dene whether the dedicated
downmix outputs feed an audio only zone or an audio video zone. When A/V, lipsync adjustment is available in that zone’s remote control functions, and that zone’s general delay can be set using the setting below.

Audio/Video General Delay per AV Zone

Set the global lip sync delay for each theater, A/V, and Headphone zone here. Max value is 250 ms.

System Setup

Enable fast boot to substantially decrease power on time of the SP4 at the expense of greater standby power consumption.

Standby Timeout: Length of time elapsed
between active use of screen and reduction of brightness to standby level.
Zoom on Changes: When on, changes made
via remote control (input, volume, etc.) will temporarily be shown in a large type so these changes can easily be read from across the room.

IR Remote Control Function Assignment

Expand Inputs and/or presets to assign up to 6 inputs and 5 presets to discrete buttons on an IR remote control. Note that many “universal” remotes also have the ability to cycle through all available inputs or presets so even if you have more than 6 or 5 respectively setup, they can still be accessed via IR. Remember that the SP4 has no front panel IR receiver, so any IR commands need to be sent to a module connected to the IR input on the back panel.
Audio Control Range MAX: Set the maximum
allowable volume. +6db (default), +3dB, 0dB.
Volume Dim Level: To quickly attenuate the volume
(but not mute it), a user can click Volume Dim. Set the level of attenuation here. Default is -20dB.

Presets

Presets provide the installer with a way to group
specic settings together into a scene which can
be easily recalled by the end user from a remote control interface. By using presets, the installer can make use of the SP4 - a highly complex and capable theater controller - extremely simple and enjoyable to operate.
Each preset includes the following settings:
1. Preset Name
Title the preset according to the usage case. For instance, if the entire family gathers together to watch movies, Movie Night. Max of 12 characters.
2. Active
When Y, the preset shows up in the list of selectable presets on the remote control. When N, the preset information is retained, but not available to select from the remote control.

9. Delete / Create
Delete any unused presets by clicking Delete in the correct row. Create a new preset by clicking Create.
3. Theater
The preset must include which theater to play. The list includes Theaters, Child Theaters, and if the optional SphereAudio license is installed, SphereAudio. It does not include zones.
4. Prole
Each theater can have multiple proles to choose from. Select the prole which will be
loaded by default when the preset is chosen.
5. Dirac Room / Dirac Curve

is Native, you will see activity on LF, CF, RF, SUB, LS and RS channels. Useful for verifying if audio
should be present on an output.
6. HDMI/DOWNMIX
Visualize audio output on the HDMI outputs and
XLR downmix outputs.
7. Logging
Logging is a useful feature to help identify
strange behavior with potential problems caused by heat. Click the graph button to show a line chart of either temperature or fan speed over time. Use the options in the popup to choose timeframe, zoom or move around the plot or export the image.
8. Details
Click to expand a window showing detailed information about audio and video coming into the player including format, resolution, color space, copy protection and more. Important information about the video transmission is also detailed. Compare this information against the compatibilities of connected hardware to diagnose errors in picture or sound. Further, it shows real time health of various power supplies
in the unit which power specic modules. This
can be a useful tool to diagnose features that are malfunctioning.
5. Outputs
Visualize real time audio output of each output channel on the rear panel. For instance, if 5.1 audio is being received and the current upmix

Web UI Remote Control

Using any modern device with a web browser, one can access the remote control. When not logged in as an expert user or installer, the remote is accessible as well, but the header (above Main Source) is not visible. The web UI remote control is best used with a computer or tablet. It can be used
with a mobile phone, but items do not properly t
the screen. iPad users can also download the iPad app from the app store.
1. Input Select
Any inputs enabled on the Inputs setup page will appear here titled according to your setup. See “Input Settings” on page 12. The currently selected input will be highlighted in blue. Tap any input to select it.

5. Preset & Audio Decoder Options
Use the Preset dropdown menu to select the desired preset. Remember that Preset includes activating
a specic theater, so if your SP4 includes multiple
theaters, you should have presets available for each. See “Presets” on page 28.
Audio Stream: Indicates real time information about the incoming audio of the selected source.
Preferred Upmix: Native plays audio back in the recorded format and/or channel count according to

the source material. Stereo Downmix will downmix surround material to 2 channel played through front
le and right (and sub if loudspeakers are congured as Small or Large and Sub) loudspeakers only.
Dolby Surround, DTS Neural:X and Auro-Matic will force any legacy surround audio into one of these 3
formats. Immsersive source audio will be rendered natively and this selection will be grayed out.
DRC: Dynamic range control for Dolby and DTS streams. On will reduce the range of volume levels on the soundtrack by compressing the loudest sounds. Auto will engage DRC when directed to by the soundtrack.
6. Triggers
Any triggers congured for Manual Switching
(see “Triggers” on page 26) will have a button available here. Clicking one of these buttons will toggle the trigger and therefore the connected device.

adjust the delay either per source (“7. AV Delay” on
page 13) or for the entire theater (“Audio/Video
General Delay per AV Zone” on page 27).
8. Zone Control
Within the conguration for each preset, you
may select auxillary zones which may be enabled. If zones are enabled for the currently selected preset, you may choose them from the dropdown menu and individually adjust volume, bass, treble, mute for each. A/V and Headphone zones also include a temporary lipsync adjustment.
