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 P ROTECTION LEDs (see Figure 3 ) will illuminate yellow .

SONAMP ® 875D SE 8-CHANNEL AMPLIFIER Source Connections (see Figures 6 & 7 ) INPUT Always use quality high-fidelity interconnect cables such as Sonance MediaLinQ ® Bronze Interconnects. If source components are more than 20 feet from the amplifier, use the Sonance LS2 and LR2 Balanced Line-Level Sender and Receiver (sold separately) to avoid signal degradation. L NOTE: Always check local building codes before installing wire in walls or ceilings.
SONAMP ® 875D SE 8-CHANNEL AMPLIFIER Input Sensitivity Adjustment There are two ways to adjust the individual channel input sensitivity (volume) on the 875D SE: • The front panel has recessed adjustment potentiometers (see Figure 9 ). These can be adjusted using a small screwdriver. 3–4 • Input sensitivity can also be adjusted by serial command via the amplifier’s RS-232 connection (see page 14).
SONAMP ® 875D SE 8-CHANNEL AMPLIFIER 6. Press the removable connector into the corresponding zone speaker connector on the amplifier until it locks into place. • 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.
SONAMP ® 875D SE 8-CHANNEL AMPLIFIER Auto-On TRIGGER MODE AUTO VOLT AUTO CH 3/4 VOLT AUTO CH 5/6 VOLT AUTO CH 7/8 VOLT OFF ON You can set your 875D SE so that any zone will automatically turn ON when it receives an audio signal, or when it receives a control voltage from an external source (such as a Sonance Navigator Harbor multi-zone controller).
SONAMP ® 875D SE 8-CHANNEL AMPLIFIER OFF (Bypass) Mode When a zone’s A UTO and V OLT Auto-On Trigger switches are both set in the OFF position, the A UTO -O N circuitry is bypassed and the amplifier’s front-panel P OWER button will turn all zones ON and OFF simultaneously (see Figure 2 , on page 5). BBE CONTROL OFF LOW OFF LOW OFF LOW OFF LOW The Sonamp 875D SE incorporates BBE ® Sound Enhancement.
SONAMP ® 875D SE 8-CHANNEL AMPLIFIER Zone Trigger Outputs The 875D SE has individual T RIGGER O UTPUT connections for each zone that provide 12V DC whenever the zone is ON (see Figure 18 ). This trigger can be used to control other devices such as Sonance AL2/AS2 automatic secondary switches, other Sonamps or 12V relays. • The current draw on each zone’s T RIGGER O UTPUT connection should not exceed 200mA.

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. E x a m p l e : 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”. E x a m p l e : A “:V7?” poll is received (What is Zone 7 volume?). Since there is no Zone 7, the 875D SE echoes back “ERR”. 3.
