SONAMP® 875D SE 8-CHANNEL AMPLIFIER  
Introduction  
Thank you for purchasing the Sonance Sonamp® 875D SE power amplifier. The 875D SE will provide you with many years  
of home entertainment enjoyment. This manual will teach you all about your new amplifier’s many innovative features and  
will show you how to get the very best performance from your amplifier. Please read it thoroughly.  
Design and Features  
Power  
The Sonamp® 875D SE is a hybrid amplifier that  
combines digital amplification with analog  
power supplies. Its Class T amplifier with Digital  
Power Processing™ technology delivers the  
high efficiency of digital (Class D) amplification  
with the superior sound quality of analog (Class  
®
Figure 1: Sonamp 875D SE  
AB) amplifiers. This allows the 875D SE to deliver high power (75 watts RMS per channel @ 8 ohms x 8 Channels) in an  
exceptionally small (2U rack height) package. And unlike conventional digital amplifiers which cannot operate in bridged  
configuration, the 875D SE’s Class T circuitry allows you to operate it with any of its four pairs of channels in a bridged  
mode, providing 300 watts x 4 channels into an 8-ohm load. Four independent power supplies (one for each zone) supply  
plenty of current, so each zone can maintain full performance regardless of how hard any other zones are being driven.  
BBE® Sound Enhancement  
The Sonamp 875D SE incorporates BBE® Sound Enhancement. The BBE process improves the presence and detail of speakers,  
especially at lower listening volumes, improving the sound quality of your music — especially distributed audio systems  
playing background music. BBE also restores clarity and definition (or focus) to spoken voices, which makes paging  
systems easier to understand without having to run them at high volumes. Each zone in the 875D SE has individual  
controls that let you set the BBE enhancement for that zone to +9dB, +6dB or OFF. The factory default setting is +6dB.  
Inputs and Triggers  
Multiple audio input connections (DIRECT, L/R & AUX) and buffered line outputs make your 875D SE extremely flexible, so  
you can connect the amplifier in a variety of ways depending on your particular system’s configuration. The Illustrations on  
pages 15 – 20 show the 875D SE being used in several different possible system configurations. Each zone has its own 12V  
input and output triggers and defeatable auto-on signal sensing that can automatically turn the amplifier ON. Recessed  
front-panel controls are tamper-resistant, and let you adjust each channel’s input level and each zone’s auto-on sensitivity.  
Front-panel LEDs tell you if the 875D SE’s power is on or off, if each Zone is on or off, and the BBE status and fault status  
for each zone.  
Serial Control Capability  
The 875D SE’s RS-232 connection lets you use a variety of 3rd-party serial control systems to control the amplifier.  
The serial control provision lets you control almost all of the 875D SE’s functions, and also lets you monitor the amplifier’s  
operation from a remote location.

SONAMP® 875D SE 8-CHANNEL AMPLIFIER  
Box Contents  
Your Sonamp 875D SE box should contain the following items:  
(1) Sonamp 875D SE amplifier  
(2) Rack ears  
(6) Removable control connectors — connected to the amplifier’s rear panel  
(4) Removable speaker connectors — connected to the amplifier’s rear panel  
(1) IEC Power cable  
Unpacking  
Save the shipping carton and polystyrene inserts so you can safely transport your amplifier in the future. Before you install  
the amplifier, locate the serial number on the rear panel and note it here for future reference:  
S/N: __________________  
Placement  
IMPORTANT: To avoid damage, the amplifier must always rest on its four feet to allow sufficient  
clearance for proper ventilation.  
Place the Sonamp 875D SE on a level surface, in an upright position, out of direct sunlight and away from windows  
through which rain may enter.  
Situate the amplifier away from heat sources such as hot air ducts or radiators. Be sure that the amplifier is adequately  
ventilated by convection cooling or suitable cabinet fans.  
IMPORTANT: The 875D SE requires four inches of clearance on the top and all sides.  
• Never place any object on or against the amplifier.  
• Never operate the amplifier on a carpeted surface as this will compromise ventilation.  
• When the amplifier is installed in any cabinet, the front or back must be open during operation. Alternately, install fans  
in the cabinet to assure continuous ventilation.  
• When rack-mounting, use nylon washers on both sides of the ears to isolate the amplifier from the rack and prevent  
ground loops and hum problems.  
• Very sensitive low-level sources might pick up some hum radiated from the 875D SE’s power supply. If this occurs, move the unit  
away from the other components.

SONAMP® 875D SE 8-CHANNEL AMPLIFIER  
Protection Circuits  
Thermal Protection  
If the amplifier’s cooling vents are blocked, or it is installed with inadequate ventilation the amplifier may  
exceed its safe operating temperature. If the amplifier’s internal temperature exceeds 154°F (68°C) it  
will self-protect, and the following will occur:  
• The audio output to all connected zones will shut OFF.  
• The front-panel PROTECTION LEDs (see Figure 3) will illuminate yellow.  
• An over-temp message will be sent via RS-232.  
PROTECTION  
BBE ON  
ACTIVE  
Once a safe temperature (<67°C) is reached, the Protection LEDs will all extinguish. You can then  
re-activate the amplifier, either by switching the front-panel Power button OFF and ON or by a ‘Power’  
command if the amplifier is being serial controlled.  
Figure 3:  
FRONT-PANEL  
STATUS LEDs  
IMPORTANT: Before re-activating the amplifier, correct the problem that caused the  
over-temperature condition (volume set too high, inadequate ventilation, etc.)  
NOTE: If you’re serial-controlling the 875D SE you can poll the amplifier at any time and its internal  
temperature will be reported to the control device.  
Over-Current Protection  
If an over-current condition occurs in a zone, that zone will shut OFF for 5 seconds and its PROTECTION LEDs will flash ON  
and OFF. The zone will then turn back ON. If the over-current condition continues the zone will shut OFF for 6 seconds,  
its PROTECTION LEDs will flash, then it will turn back ON. If the over-current condition continues this process will repeat,  
with the wait time increasing by 1 second each time. When the wait time reaches 10 seconds the zone will LOCK, the  
zone’s PROTECTION LEDs will continually illuminate and the amplifier must be powered OFF using the front-panel POWER  
button (or a serial command, if the amp is being controlled via RS-232). Before turning the amplifier ON again,  
correct whatever is causing the over-current condition in the zone (speaker impedance too low, volume too  
high, short-circuit, etc.).

SONAMP® 875D SE 8-CHANNEL AMPLIFIER  
Powering the Amplifier  
Power Cord (see Figure 4)  
The Sonamp 875D SE features a removable IEC power cord. Plug the female end of the power  
cord into the Power Cord Connector on the amplifier’s rear panel and plug the male end into a  
20-amp grounded wall socket. DO NOT plug the power cord into an AC outlet on your  
preamplifier/receiver.  
CAUTION: To prevent electric shock, do not defeat the ground prong of the  
power cord plug.  
Figure 4:  
Power Connector  
and Fuse Holder  
NOTE: If you need to use an extension cord, use only a heavy-duty (14-gauge or  
larger) extension cord to avoid starving the amplifier of all the current  
necessary for full-power operation.  
Replacing the Fuse (see Figure 4)  
CAUTION: For continued protection against fire, replace the fuse with only the same type and rating.  
1. Remove the power cord from the wall outlet and from the amplifier’s Power Cord Connector.  
2. Insert a flat-blade screwdriver or similar tool into the empty Power Cord Connector socket and gently pry the fuse holder out  
of its socket.  
3. Install the proper fuse in the fuse holder and replace the fuse holder back into its socket next to the power cord connection.  
When the amplifier is operating, the fuse will blow to protect it from possible internal parts failure. NEVER replace the fuse  
with any size other than that indicated on the rear panel to avoid more serious damage and the risk of fire. Substitution  
of a larger fuse may create serious damage to internal parts and will void your Sonance warranty.  
A.C. ON LED (see Figure 5)  
The AC ON LED indicates that the amplifier’s power cord is plugged-into a live AC outlet and  
its POWER button is ON. If the amplifier’s AC fuse ever opens, this LED will go out. To use the  
AUTO-ON feature (see page 12), this LED must remain ON at all times.  
ACTIVE LED (see Figure 5)  
The amplifier’s ACTIVE LED will illuminate whenever any zone is active. Each zone’s STATUS  
INDICATORS (see Figure 3) also contain an ACTIVE LED that will illuminate whenever that particular  
zone is ON.

• Input sensitivity can also be adjusted by serial command via the amplifier’s RS-232 connection  
(see page 14).  
Figure 9:  
NOTE: When the 875D SE is being serial-controlled, serial VOLUME commands  
will override the front-panel input sensitivity settings. However, if the front-  
panel controls are manually adjusted after the serial VOLUME commands are  
sent, they will override the volume set by the serial commands.

Speaker Connections  
IMPORTANT: Always unplug the amplifier’s power cord from the wall outlet before making source  
signal or speaker connections.  
Use Good Speaker Wire  
For the best sound you should never use thin-gauge speaker wire – it will constrict the sound and diminish bass response.  
We recommend that you use premium Sonance MediaLinQ speaker cable, which also complies with UL fire rating codes.  
You may also experiment with audiophile brands of speaker cable and interconnects, but be sure to check local codes  
governing wire that may be installed within walls or ceilings. Different brands of wire can have different characteristic  
sounds and some may be more compatible with the sonic “signature” of your various audio system components.  
Your Sonamp 875D SE is stable with any reputable brand of speaker wire or cable.  
Speaker Connections for Stereo Operation (see Figure 10)  
Flip all 4 Levers UP  
1. Run speaker wire from each speaker to the amplifier location. We recommend that you  
mark each wire’s positive (‘+’) and negative (‘–’) leads, its channel (left or right) and which  
zone it is from so that you can connect it to the proper speaker terminals.

• The removable connectors will only fit one way on the amplifier.  
CAUTION: Always provide sufficient slack in wires to avoid tension. Always contain any excess wire  
to prevent tripping hazards.  
Speaker Connections for Bridged Operation (see Figures 11 & 12)  
The 875D SE can operate with any pair of channels (zone) in the single-channel bridged mode, which delivers 300 watts  
RMS into an 8-ohm speaker. Be sure the speaker is rated to handle this increased output power.  
IMPORTANT: The minimum speaker impedance for Bridged Operation is 8 ohms. Do not operate a  
zone in the Bridged mode into a speaker that is less than 8 ohms nominal impedance.

located on the rear panel: Auto — zone is turned ON when an audio signal is present, and  
Volt — zone is turned ON by an external control voltage (see Figure 14).

AUTO (Audio) Trigger Mode  
When a zone’s AUTO switch is set to the ON position, any audio signal arriving at the zone’s active  
input connectors (as determined by the INPUT ASSIGNMENT DIP SWITCHES, see page 8) will activate  
the zone for operation. The sensitivity of the zone’s AUTO-ON circuit can be increased or decreased  
by adjusting the AUTO ON level control on the front panel (see Figure 15).

• Turning the control clockwise increases the sensitivity (less voltage is required to trigger the  
AUTO-ON function).

Trigger Sensitivity  
Adjustments  
• Turning the control counter-clockwise decreases the sensitivity (more voltage is required to  
trigger the AUTO-ON function).  
ON  
The AUTO-ON trigger sensitivity ranges from 5mV/ch in the full clockwise position to OFF (AUTO-  
ON will not trigger) in the full counter-clockwise position.  
In the AUTO-ON mode the zone will remain ON for approximately 3 minutes after the audio signal has ceased. This  
provides ample time to prevent erratic operation from pauses between musical passages or while changing sources.  
VOLTAGE Trigger Mode  
When a zone’s VOLT switch is set to the ON position it can be automatically turned ON  
by an external trigger voltage that appears at the zone’s EXTERNAL TRIGGER INPUT  
connections (see Figure 16).

SONAMP® 875D SE 8-CHANNEL AMPLIFIER  
OFF (Bypass) Mode  
When a zone’s AUTO and VOLT Auto-On Trigger switches are both set in the OFF position, the AUTO-ON circuitry is  
bypassed and the amplifier’s front-panel POWER button will turn all zones ON and OFF simultaneously (see Figure 2, on  
page 5).  
BBE® Sound Enhancement  
The Sonamp 875D SE incorporates BBE® Sound Enhancement. The BBE process improves  
the presence and detail of speakers, especially at lower listening volumes, improving the  
sound quality of your music — especially distributed audio systems playing background  
BBE CONTROL  
music. BBE also restores clarity and definition (or focus) to spoken voices, which makes  
paging systems easier to understand without having to run them at high volumes. Each  
zone in the 875D SE has 2 individual switches that let you set the BBE enhancement for  
1/2 3/4 5/6 7/8 CH  
that zone to HIGH (+9dB), LOW (+6dB) or OFF (see Figure 17):  
• If the OFF/ON switch is set to OFF, BBE enhancement is not applied  
• If the OFF/ON switch is set to ON, BBE enhancement is applied according to the set-  
ting of the LOW/HIGH switch: LOW = +6dB of BBE enhancement; HIGH = +9dB of

The 875D SE also has a set of BBE CONTROL INPUT connections that allow the BBE  
enhancement for each zone to be triggered ON and OFF individually by an external  
control voltage (see Figure 17):  
• The BBE OFF/ON switch for the zone must be in the OFF position.  
• The trigger voltage must be between 5V and 24V, either AC or DC.  
The EXTERNAL TRIGGER connectors feature flip-up levers similar to the ones used on the speaker connectors:  
1. Open the levers for the zone’s EXTERNAL TRIGGER inputs.  
2. Insert the control wires into the appropriate openings in the connector.  
3. Close the levers.  
The front-panel ZONE STATUS LEDs indicate if BBE processing is being applied to a zone (see Figure 3, on page 7).

3. Close the levers.  
Serial Control  
The 875D SE’s RS-232 Control Input (see Figure 19) allows many 875D SE functions to be  
serial-controlled by 3rd-party control systems, and allows many of the amplifier’s performance  
parameters to be monitored in real-time via the 3rd-party controller.  
RS-232  
The 875D SE’s open architecture allows you to use it with a variety of RS-232 controllers. Specific  
Figure 19:  
RS-232 Control Input  
modules for use with Crestron® and AMX® controllers are available for download at  
www.sonance.com. Please check the website for information about compatibility with additional  
controllers.  
Connecting the 875D SE to a Serial Control Device  
The 875D SE’s RS-232 Pinout is: Pin 2: RXD; Pin 3: TXD; Pin 5: GND.  
Use a null modem cable to connect the 875D SE’s RS-232 CONTROL INPUT to a serial control device. To verify the pinout of  
other serial devices, the TXD pin of an active port will show a negative DC voltage.  
NOTE: To connect to a Crestron controller, use the Crestron CNSP-124  
cable (available separately from Crestron).

To enable serial control of of a zone, both of that zone’s AUTO and VOLT Trigger Mode  
switches must be set in the ON position (see Figure 20). Setting a zone to RS-232 disables  
its rear-panel Auto and Voltage trigger functions — they can only be serial-controlled.

SONAMP® 875D SE 8-CHANNEL AMPLIFIER  
Serial Control Notes:  
1. The 875D SE will respond to each command with the new value after the command is acted-upon.  
Example: Zone 2 volume is 53. If a “:V2+3” (increase Zone 2 volume +3 steps) command is then issued, the 875D SE  
echoes back (V256) (Zone 2 volume is 56).  
2. The 875D SE will respond to invalid commands with “ERR”.  
Example: A “:V7?” poll is received (What is Zone 7 volume?). Since there is no Zone 7, the 875D SE echoes back “ERR”.  
3. The 875D SE will respond with “N/A” if a recognized command cannot be executed.  
Example: Zone 4 is OFF when a “:V4?” (What is Zone 4 volume?) query is received. Since Zone 4 is OFF, the 875D SE  
echoes back “N/A”.  
4a. Any command followed by a “?” will be treated as a Query and will cause the 875D SE to echo back the current state  
for that zone (z) or channel (c).  
Example: Zone 4 is OFF and a “:P4?” query is received. The 875D SE echoes back “P40” (Zone 4 power is OFF).  
4b. A command followed by a “G?” will be treated as a Global query and will cause the 875D SE to echo back the  
current state of each zone or channel.  
Example: A “:BPG?” (Is BBE ON or OFF in Zones 1 – 4?) query is received. The 875D SE echoes back:  
BP11 (Zone 1 BBE is ON); BP21 (Zone 2 BBE is ON); BP30 (Zone 3 BBE is OFF); BP40 (Zone 4 BBE is OFF)  
5. When an over-temperature or fault condition occurs, activating the amplifier’s protection circuits, the 875D SE will issue  
an unsolicited echo reporting that condition.  
Example 1: If the temperature inside the amplifier reaches 68°C, it will issue the unsolicited echo “TP68”.  
Example 2: If Zone 1 experiences a fault the amplifier will issue the unsolicited echo “FP1”.  
6. When the amplifier is plugged-in it will automatically issue its AMX beacon.

Features: Channels automatically activated by controller • Each zone can be controlled by in-zone keypad  
The 875D SE is ideal for use with a multi-zone controller like the Sonance Navigator® Harbor. By connecting the Navigator  
Harbor’s Zone Keypad Status + and – terminals to the 875D SE’s External Control Input connections, the controller will  
automatically turn the amplifier’s channels ON and OFF as they are needed.
