ALR-AMP-8 Alero 8 Zone Power Amplifier
Installation
Mounting the Alero into an Equipment Rack
The Alero ALR-AMP-8 can be mounted in a 19" equipment rack or on a solid flat surface.
Use the included removable rack ears and removable feet for mounting.
Ventilation
To ensure that the rack enclosure is adequately ventilated, there must be a minimum of 3" all around the Alero
unit.
Sufficient airflow must be achieved (by convection or forced-air cooling) to satisfy the ventilation
requirements of all the items of equipment installed within the rack.
Rack Mount Safety Instructions
Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
Consideration should be given to the connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on over current protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to
supply connections other than direct connections to the branch circuit (e.g. use of power strips).
Wiring and Connections
Connecting Audio Source Devices
Source Devices connect to the Audio (Signal) Inputs connectors on the rear panel. (FIG. 4):
The Audio Inputs consist of 16 RCA/phono terminals; each of the single-ended input channels having a signal
input and ground.
Each Zone (1-8) consists of two channels (odd and even) that represent the left and right channels in a stereo
pair. For example, CH1 and CH2 represent the left and right channels for Zone 1.
The maximum operating ambient temperature is 45°C (113°F).
All speaker wire connections must be made with the amplifier off. The amplifier must
be off whenever you make changes to the input connections.
