TOA Electronics 4-Channel Digital Amplifier (500W Per Channel, 70V)...
Product Overview
The TOA DA-500F-HL is a 4-channel Class D digital power amplifier built for multi-zone commercial audio systems that demand high output in a compact rack space. This 4-channel power amplifier provides an independent power section for each channel, along with control and monitor terminals for per-channel power switching and status monitoring. It is well suited to large-zone paging, background music, and sound reinforcement in commercial facilities, and mounts in a standard 2RU EIA equipment rack.
Product Description
The DA-500F-HL uses efficient Class D circuitry to deliver high power with low heat dissipation and low power consumption, allowing units to be stacked without open spaces between them. Each channel has a front-panel level control, a removable terminal-block input, and a built-in limiter and high-pass filter to help protect connected loudspeakers. Control and monitor terminals allow an external control panel or status display to switch power per channel and report power, protection, and fan status.
Comprehensive protection circuitry guards against overheating and overload, and front-panel LEDs indicate power, input, output, peak, and protect status for each channel. Volume control caps are included to prevent accidental level changes after commissioning. Browse other TOA power amplifiers to match the amplifier to your zone count and power requirements.
Key Features
- Four independent channels — Each channel has its own power section for reliable multi-zone operation.
