The P-912MK2 from TOA Electronics is a 120 watt single-channel modular amplifier ideal for paging, background music, or on-hold music. It offers a wide frequency response, low noise and distortion, and TOA's well-known quality and reliability. It has a single module slot for easy custom configuration using TOA plug-in modules. The system also has a direct input so that it may be used without an input module.

The P-912MK2 has a selectable input sensitivity to accommodate high or low inputs levels, a low cut switch to limit low frequency response, a master volume control, indicators for normal, signal, power, protect, and signal, and a turn-on delay which disconnects the output during power-up to prevent shock to the speakers.

    Comments about Toa Electronics P-912MK2 120 Watt Single-Channel Modular Power Amplifier:

    We use TOA amps wherever we can. They are rock-solid reliable and have many module choices for auxiliary functions. Don't forget to order the rack-mount kit separately as it is not included.
