Mezzo 324 A+ heralds the same levels of reliability, build quality, and acoustic proprieties of any Powersoft amplifier platform, in half the size. Exceedingly flexible, “A+” versions of Mezzo offer all the remote control and monitoring functions of the “A” versions, further extending networking capabilities with AES67. The small form factor allows it to be mounted anywhere thanks to the included mounting kit, the 320 W versions of Mezzo can also be mounted in air handling spaces, such as double ceilings or wall boxes.
