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.
The T
RIGGER
O
UTPUT
connectors feature flip-up levers similar to the ones used on the
speaker connectors:
1. Open the levers for the zone’s T
RIGGER
O
UTPUTS
.
2. Insert the control wires into the appropriate openings in the connector (observe the correct “+” and “–” polarity).
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
w w w w w w .. ss oo nn aa nn cc ee .. cc oo m m . 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: PP ii nn 2 2 :: RR X X D D ;; PP ii nn 3 3 :: TT X X D D ;; PP ii nn 5 5 :: G G N N D D ..
Use a null modem cable to connect the 875D SE’s RS-232 C
ONTROL
I
NPUT
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 A
UTO
and V
OLT
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.
NOTE: Zones not set for RS-232 control can be polled by the control
device, but cannot be controlled by the device.
