Product description The Alpha Amplifier System from AER is a 40W amplifier with an 8" twin-cone speaker system. It has one channel and two independent input stages (line and microphone/line). The triple-band equalizer of your Alpha provides you with an active sound interaction tool that supports the natural tone of instruments and voice whilst simultaneously offering you the possibility of a controlled accentuation.
The Alpha has a built-in (internal) reverb effect. The EFX level control determines the intensity of the internal effects. A standard double footswitch (on/off switch) can be plugged into the footswitch socket on the rear side of the amplifier via a stereo cable. The footswitch allows you to switch the internal and external effects on and off.
Microphones requiring 48V phantom power can be directly connected to the XLR socket of input 1. Factory-provided phantom power is activated but if required, may be deactivated by an internal jumper. In contrary 9V phantom power, if required, can additionally be activated in input 2 by an internal jumper.
