Zone Trigger Outputs, Serial Control

SONAMP® 875D SE 8-CHANNEL AMPLIFIER

Zone Trigger Outputs

The 875D SE has individual TRIGGER OUTPUT 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 TRIGGER OUTPUT connection should not exceed 200mA.

The TRIGGER OUTPUT connectors feature flip-up levers similar to the ones used on the speaker connectors:

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.

The 875D SE’s open architecture allows you to use it with a variety of RS-232 controllers. Specific modules for use with Crestron® and AMX® controllers are available for download at

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) .

Enabling 875D SE Zone Serial Control

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-232disables its rear-panel Auto and Voltage trigger functions — they can only be serial-controlled.

NOTE: Zones not set for RS - 232 control can be polled by the control device, but cannot be controlled by the device .
