TOA Electronics 120 Watt Single-Channel Modular Power Amplifier - P-912MK2 UL

Product Overview

The TOA P-912MK2 UL is a 120 W single-channel modular power amplifier built for paging, background music, and on-hold music in commercial systems. A single module slot accepts TOA plug-in input modules for custom configuration, and a direct input allows use without an input module. The amplifier provides 25 V, 70 V, and 8-ohm transformer-isolated outputs to match a range of speaker layouts. It is a UL-listed, commercial-grade amplifier suited to distributed audio in offices, retail, and public spaces.

Product Description

The P-912MK2 delivers 120 W with a wide frequency response and low noise and distortion for clean paging and music reproduction. Its module slot accepts a variety of TOA plug-in modules for easy customization, while a direct input connects an audio source without a module, and a direct low-impedance output mode supports non-transformer operation. Selectable input sensitivity accommodates high or low input levels, and a low-cut switch limits low-frequency content for speech systems. A master volume control with an included security knob, plus status indicators for normal, clip, power, protect, and signal, keep operation clear in the rack. Protection circuitry guards against overload, short circuit, and overheating, and a turn-on delay disconnects the output at power-up to protect speakers. Optional rack-mount kits are available for clean integration. Explore more TOA power amplifiers at Creation Networks.

Frequently Asked Questions

What speaker systems does the P-912MK2 support? It offers 25 V, 70 V, and 8-ohm transformer-isolated outputs, plus a direct low-impedance output mode.

Can I use it without an input module? Yes. A direct input lets you connect an audio source without a plug-in module, or you can fit a TOA module in the slot.

How does it protect connected speakers? A turn-on delay disconnects the output at power-up, and protection circuitry covers overload, short circuit, and overheating.

Is it rack-mountable? Yes. Optional TOA rack-mount kits are available for clean installation.

What is the low-cut switch for? It limits low-frequency content, which helps intelligibility in speech and paging applications.

What warranty and support apply? The amplifier is UL listed and carries the TOA manufacturer warranty; contact Creation Networks for warranty, stock, and AV integration support.
