TOA Electronics 240 Watt Single-Channel Modular Power Amplifier - P-924MK2 UL

Product Overview

The TOA P-924MK2 UL is a 240-watt single-channel modular power amplifier built for distributed paging, background music, and on-hold audio in commercial AV systems. A single plug-in module slot lets integrators match the input stage to the application, while transformer-isolated 25V and 70V outputs drive long 70-volt speaker lines across large facilities. A direct low-impedance mode and 8-ohm output add flexibility for full-range or local loads.

Product Description

The P-924MK2 UL delivers 240 watts of clean output from a compact, rack-mount chassis, making it a practical amplifier for paging and music distribution in commercial buildings. Selectable input sensitivity accommodates both high- and low-level sources, and a low-cut switch limits unwanted low-frequency energy for clearer speech. The master volume control and front-panel status indicators for normal, clip, power, protect, and signal give installers clear feedback during setup and daily operation. A turn-on delay disconnects the output during power-up to protect connected speakers, and built-in protection circuitry guards against overload, short circuit, and overheating. The single module slot accepts TOA plug-in modules, while a direct input allows the amplifier to be used without an input module. An included volume control security knob helps lock settings in shared spaces, and optional rack-mount kits support clean integration into equipment racks.

Key Features

• 240W single-channel output — Provides ample power for paging and background music across large commercial zones.
• Modular input slot — Accepts TOA plug-in modules so the input stage can be configured for mic, line, or other sources.
• Transformer-isolated 25V and 70V outputs — Supports long, high-impedance speaker runs typical of distributed commercial systems.
• Direct low-impedance and 8-ohm output — Allows the amplifier to drive full-range or local loads without a transformer.
• Selectable input sensitivity and low-cut switch — Matches a range of source levels and improves speech clarity.
• Comprehensive protection circuitry — Guards against overload, short circuit, and overheating for reliable operation.
• Turn-on delay — Disconnects the output at power-up to prevent transient shock to connected speakers.
• Status indicators and security knob — Show normal, clip, power, protect, and signal states while locking volume in shared rooms.

Typical Applications

• House of worship
• Auditorium
• Multi-purpose room
• Commercial meeting space
• Training room
• Government space

Technical Specifications

Frequently Asked Questions

Is the P-924MK2 UL compatible with 70V speaker systems? Yes. It provides transformer-isolated 25V and 70V outputs for high-impedance distributed speaker lines, plus an 8-ohm output and direct low-impedance mode for local loads.

Does it require an input module? No. The amplifier includes a direct input for connecting an audio source, and the module slot accepts TOA plug-in modules when additional input flexibility is needed.

Can it be rack-mounted? Yes. Optional rack-mount kits are available for clean integration into standard equipment racks.

How does it integrate into a larger AV system? It accepts mic or line sources through its module slot or direct input and feeds 70V speaker zones, serving as a zone amplifier within a distributed paging or background-music system.

What protection does it offer for connected speakers? A turn-on delay disconnects the output during power-up, and protection circuitry responds to overload, short circuit, and overheating.

Is warranty and support available? Yes. TOA products are backed by the manufacturer's warranty; contact Creation Networks for warranty details and installation support.
