The Bose® AES3 8-channel input card allows PowerMatch® configurable professional power amplifiers to receive up to 8 channels from AES3 sources such as mixing consoles and DSPs. The AES3 input card inserts into the digital expansion slot on a PowerMatch amplifier. A buffered passthrough connection on card allows digital audio to be daisychained to multiple PowerMatch amplifiers or other AES3 devices.
