Toa Electronics A-903MK2 30W 8-Channel Modular Mixer/Amplifier
From the TOA 900 series of mixer/amplifiers, the A-903MK2 is a customizable unit ideal for background music, paging, on-hold messages, and other applications in hospitals, airports, schools, and other similar venues. The A-903MK2 is designed for high performance with a low self-noise, a wide frequency response, and excellent output regulation. This 30W unit features 8 input channels that accept any combination of TOA s plug-in modules for ultimate customizability. The front panel features a master volume control and individual channel volume controls as well as bass and treble controls.
Input capacity may be increased by connecting another mixer or mixer/amplifier to the bridge in/out jack. The unit features transformer-isolated outputs, and a direct output mode if non-transformer operation is desired.
