480W BOOSTER (Endstufe)

The AW5612 booster has an RJ45 input for connection to B711-G pre-amplified microphone bases simply by means
of SFTP CAT.5E shielded cables. There is a special balanced input (TEL/EMERG) with a transformer and automatic
activation of precedence (VOX) on the rear panel. Controls for adjusting the level and the activation threshold
are present on the rear panel. This input can be used for connecting the appropriate audio output of a telephone
switchboard.
This equipment has a large number of devices for protection against overloads and short circuits (an output current
peak-limiting circuit, a thermal circuit-breaker inside the power transformer, a resettable thermal circuit-breaker in
contact with the power-transistor heat sink, mains fuses). In addition, each unit has a cooling fan, with automatic
control of the speed depending on the temperatures of the heat sinks to which the power devices are applied.
Note: Each amplifier of the AW5600 range has an electronically balanced line input/output with a double XLR
socket, one female socket and one male socket to facilitate connection of a number of boosters in cascade fashion.
To connect a source of sound directly, it is possible to use a second unbalanced input by means of a double RCA
socket for using standard stereo cables.
