Installation
SRA-Series amplifiers are designed for use in both fixed and mobile sound systems. Each
amplifier is shipped (unless otherwise specified) with the following factory settings:
Front panel: Rear panel:
On/Off Switch = Off
Attenuators = ∞
High Pass Filter(s) = Off
Gain Selector = +26 dB
Mode Selector = Stereo
Before connecting to mains power, make sure that the switches are set to the configuration
needed for your particular application. Always switch the amplifier off before making any
changes to the settings. Failure to do so could result in damage to the unit or other components
in your system. CAUTION: When mounting or connecting the amplifier, always disconnect it
from the mains. Use four screws and washers when mounting the amplifier to the front rack
rails. Rear support is also recommended, especially for mobile or touring use. To reduce the
risk of fire or electric shock, do not expose this apparatus to rain or moisture.
Requirements
SRA-Series amplifiers have specific physical, electrical and signal requirements for proper
operation. These requirements will vary depending on your specific application, setup, and
the settings on the amplifier. When setting up and testing your system, please take special
care to double check all connections and settings. Please refer to the specifications section
of this manual for specific input, output and other figures.
Installation Density
SRA-Series amplifiers produce substantial power output from a very small chassis. When
driven at the higher-end of their potential, they do produce heat that must be dissipated. In
cases where multiple SRA amplifiers are mounted together (or a single SRA with other
equipment), it is recommended that a 1RU space is left between units to allow for proper
air circulation. If the amplifier overheats, it will go into ‘thermal’ protect mode to prevent
damage to itself and any connected components and speakers.
