Mezzo 604 AD heralds the same levels of reliability, build quality, and acoustic proprieties of any Powersoft amplifier platform, in half the size. Exceedingly flexible, “AD” versions of Mezzo offer all the remote control and monitoring functions of the “A” versions, further extending networking capabilities with Dante and AES67. The small form factor allows it to be mounted anywhere thanks to the included mounting kit.
