A2 Series

2-Channel Amplifiers

The A2 Series, two channel power amplifiers offer very affordable sound quality while still providing professional features such as balanced XLR inputs and Speakon TM speaker connectors. The rugged chassis and compact size (2U / 3.5" high, 10" deep) makes for easier shipping and installation in rack equipment. The A2 Series amplifiers are especially suited for monitor and fixed application in clubs, restaurants, stores, churches or hotels where a low cost, compact dual-channel amplifier is required.
