TOA Electronics Modular Digital Mixer/Amplifier (2 x 120W @ 70V) - A-9120DHM2CU

Product Overview

The TOA A-9120DHM2CU is a modular digital mixer/amplifier that pairs dual 120-watt 70V outputs with onboard DSP for multi-zone paging and background music in commercial AV installations. Eight configurable input slots accept TOA 9000- and 900-series plug-in modules, so integrators can build the exact mic and line configuration a conference room, house of worship, or multi-purpose facility requires. PC-based GUI programming keeps setup and ongoing maintenance straightforward.

Product Description

The A-9120DHM2CU combines a matrix mixer, dual-channel digital amplifier, and signal processing in a single 2RU chassis. Its dual-channel DSP includes a 10-band parametric EQ, high- and low-pass filters, bass and treble controls, a compressor, gate, ducker, and delay, giving installers detailed control over each output zone. The GUI programming interface makes it straightforward to configure the unit from a PC and to upload or download settings over the RS-232 connection, with setup wizards and a firmware-upgrade utility simplifying maintenance. An integrated operating mode lets mixer functions run at the same time as paging-matrix activation, which suits multi-zone and telephone paging with prioritized presets and recallable memory settings. Automatic mic mixing and ambient noise control help maintain consistent intelligibility in changing rooms. Two RCA unbalanced inputs and outputs handle local sources, and plug-in modules expand connectivity as needed (modules are sold separately).
