TOA Electronics 8-Channel Mixer Preamplifier - M-900MK2 Audio Amplifiers TOA
Overview
The TOA M-900MK2 is an 8-slot modular mixer preamplifier that accepts any combination of TOA plug-in input modules. With a balanced transformer-isolated output delivering up to +20 dBm and a vanishingly low 0.01% THD, it is the central control hub in TOA commercial paging and background music systems.
Description
The M-900MK2 provides a flexible, user-configurable mixing platform for small to medium commercial AV installations. Its eight module slots accept any TOA plug-in input module — including microphone, line, telephone interface, tuner, and priority input modules — enabling you to tailor the system precisely to your application without external adapters. A bridging RCA jack expands the system by linking multiple M-900MK2 units. Individual channel potentiometers, bass and treble tone controls (±10 dB), and a master output pot give complete front-panel control. Status LEDs monitor power, peak, protect, signal, and normal conditions at a glance, while dual mute buses and protection circuitry guard system integrity.
