Description
The TOA 900 Series are widely recognized as the industry standard in installed sound system amplification. When reliability and performance are critical - such as in paging and music distribution for airport, hospital, and industrial sound systems - you can count on the TOA 900 Series to perform consistently, day-in and day-out.
The A-912MK2 (120 W) Modular Mixer/Amplifiers are engineered for high performance with wide frequency response, very low noise and distortion, and excellent output regulation.
Features:- Modular Eight Channel Mixer/Amplifiers for paging, background/foreground music distribution and music/messaging-on-hold.
- Proven TOA Quality and Reliability
- Engineered for High Performance with wide frequency response, very low noise and distortion, and excellent output regulation.
- Three Models: A-903MK2 (30 W), A-906MK2 (60 W), A-912MK2 (120 W)
- Eight Module Slots accept any combination of TOA plug-in modules for custom system configurations.
- 25 V, 70 V and 8 Ohm Transformer-Isolated Speaker Outputs with screw terminal connector and protective cover plate (A-903MK2: 4 ohm).
- Direct Low-Impedance Output Mode bypasses output transformer.
- Dual Mute Bus permits multiple levels of paging priority using optional mute-type modules.
- External Mute Terminals for activating mute function with external switch closure.
- Remote Master Volume Terminals for control with an external 10k ohm linear-taper potentiometer.
