AER redefines acoustic amplification with the Alpha. Based on the experience with the Compact 60, AER has developed an even smaller, lighter model that has no difficulties living up to the rigors of the road. Conforming to AER's usual high quality standards, the Alpha is a full sized member of the AER product family: open-sounding and quick in response, this amp masters different ranges and always cuts through other instruments. Combined XLR and1/4 inch input with 24V phantom power, 1/4 inch secondary input, three band tone controls, digital reverb. 40W/4 Ohm RMS with 8 inch twincone speaker system.
