4 Channel 125W, 2 Channel 70/100V 250W DSP Matrix Amplifier

Model: RTI-AMP4-125

  • Four analog audio source input channels (balanced or unbalanced) and one digital input (S/PDIF).
  • Two Lo-Z stereo or four Lo-Z mono output zones, two Hi-Z mono output zones, or a mix of them.
  • A Class D amplifier provides a robust and clear audio experience with 125 Watts @ 4O/8O 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.

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 4Ω to 16Ω loudspeakers and high-impedance 70V/100V transformer-coupled loudspeakers. The AMP-4-125 accepts four analog inputs (balanaced and unbalanced) 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.

Included in the box:
AMP-4-125, power cord, 6-pin Phoenix input connectors (2), 4-pin Phoenix output connectors (2), 8-pin Phoenix GPIO socket connector (1), adhesive rubber feet (4).
