ALR-AMP-8 Alero 8 Zone Power Amplifier

System Diagram

FIG. 3 provides a basic system diagram showing the Alero in a NetLinx System:      

This example shows eight stereo audio source devices connected to the Alero ALR-AMP-8, and eight stereo Zones for 
audio output. 



The Alero also supports a 

Bridge Mode

 (BTL) configuration. Bridge Mode converts one stereo pair into a 

single, stronger amplification channel. If all Zones are bridged, there are 8 channels available.



Stereo and Bridged Zones can be mixed as necessary (see the 

Connecting Audio Source Devices

section on 

page 5 for details).

Controlling the Alero ALR-AMP-8

Volume control for the Alero ALR-AMP-8 is managed by an external pre-amp / audio switcher, such as the AMX Precis 
DSP (Fixed Matrix Switcher with Stereo Audio with RCA Digital Volume Control and Digital Signal Processing).

The Alero ALR-AMP-8 can be powered on and off externally by using the two signals 12V trigger and 3-5V trigger. A 
Signal Sense function is also provided which automatically can switch on the Alero in the event of an audio signal and 
switch off the Alero to enter standby mode when no audio signal has been present on the signal terminals for 
approximately 13 minutes. 

Refer to the 

On/Off Control (12V Trigger, 3-5V Trigger and Signal Sense)

section on page 14 for details.
