Sonance SONAMP 875 Crestron Module V2
Application Guide
Description
This module allows a Sonance SONAMP 875 amplifier to be controlled by any X-Generation or
2-series Crestron control processor
NOTE: The amplifier must be properly configured to enable RS-232 control. Refer to
the Amplifier’s Instruction Manual for specific instructions. The amplifier’s power
switch must be in the “On” position and the “A.C. On” indicator illuminated for the
amplifier to be controlled or monitored.
Supported Processors
(no compact flash support required)
Any X-Generation or 2-Series Crestron Processor
Module Application
It is strongly suggested that you load the supplied demonstration program and touchpanel to
gain an understanding of the application of the module before you attempt to implement the
module in your own program.
This module provides control for four zones (consisting of a total of eight individual
channels) on the Sonance SONAMP 875, including power, mute, BBE and feedback for fault
indication, front panel trim pot levels, and audio and voltage trigger input status.
This module allows you to set the volume and mute for either a zone or channel (a zone is a
left and right pair. For example, Zone 1 is channels 1 and 2, Zone 2 is channels 3 and 4,
etc).
You should use only the zone or channel volume controls for each channel or channel pair on
the amplifier, they should not be used simultaneously. The power for a zone, however, must
be on to control either of the channels that belong to that zone.
Zone Number Channel Number
Zone 1
Zone 2
Zone 3
Zone 4
If a fault is reported, the amplifier’s power feedback will automatically be forced low. You
may attempt to clear the fault by pulsing the [zoneX_power_on] or [zoneX_power_tog]
digital inputs.
It is suggested that you pulse the [poll_all] input once at program startup to determine the
current status of the amplifier, most status changes will be automatically reported by the
amplifier and processed by the module when the module is running.
(Note: Audio and Voltage Triggers are not automatically reported by the amplifier. If you are
utilizing these inputs, it is necessary to periodically poll the amplifier by pulsing either the
[poll_all] digital input to pull all inputs, or alternatively, pulsing the
[zoneX_poll_voltage_trigger] or [zoneX_poll_audio_trigger] inputs. The accuracy of the audio
trigger varies depending on program volume level, content, and the setting of the “Auto On”
trim pot on the amplifier’s front panel.
