Speco 120W 5-Zone PA Mixer Amplifier PBM120A with Module Bay
Five zones. One mixer amp.
The Speco PBM120A is a 120W RMS PA mixer amplifier with a module bay. It combines microphones and music sources and drives up to 5 zoned 70 or 25V speaker outputs for paging and background music.

Paging and music rarely need the same volume
Commercial sound systems mix microphones and music sources across several areas. Each source and each zone has to be controlled without one drowning out another.
Built for paging and background music
The PBM120A packs mixing, zoning and tone control into one rack-mountable amplifier.
5 zoned speaker outputs
Five zoned 70 or 25V speaker outputs let you send sound to different areas, plus a non-zoned 4/8/16 Ohms output.

RMS output power
Rated RMS output across a 5-zone mixer amplifier.
Priority paging with phantom power
Phantom power is available for all Mic inputs, and Mic1 has selectable priority paging.
Full volume control
A master digital volume control with display is joined by an individual volume control for each input.
Remote and rack kit included
An IR remote and rack-mounting kit come with the amplifier, and front bass and treble controls let you shape the sound.
