A Class D amplifier provides a robust and clear audio experience with 125 Watts @ 4Ω/8Ω per channel or 250 Watts @ 70V/100V per channel.
Daisy-chain multiple amplifiers to expand the number of zones by distributing up to two audio inputs or zones.
Built-in DSP allows fine-tuning of acoustic characteristics for each zone.
Easy configuration via LAN or Wi-Fi.
Offers IP and GPIO control options.
Free-standing installation or rack-mount (rack-mount kit included).
Overview:
The AMP-4-125 power amplifier delivers configurable and reliable high-performance audio power amplification for commercial and hospitality applications requiring a mix of low-impedance and high-impedance outputs. Featuring a compact 1U half-rack design, this DSP-enabled Class-D amplifier supports low-impedance 4O to 16O loudspeakers and high-impedance 70V/100V transformer-coupled loudspeakers. The AMP-4-125 accepts four analog inputs and one stereo S/PDIF digital input, delivering four low impedance mono channels (or two low impedance stereo zones) at 125W per channel, or two 70V/100V mono channels at 250W per channel.
For setup, the RTI web GUI offers effortless browser-based configuration of the installed system. DSP configuration options include multi-zone setup, input mixing, priority and ducking, restrictions, input and output EQ, S/PDIF output routing, high-pass filtering, speaker presets, delay, Wall-S1 controller configuration, sine wave generation, and more.
