Pre-Order Now: AMP-8-125 - 8 Channel 125W 8Ω, 4 Channel 70/100V 250W DSP Matrix Amplifier

The AMP-8-125 power amplifier delivers configurable and reliable high-performance audio power amplification for commercial and hospitality applications that demand a mix of low impedance and high impedance outputs. With a compact 1U design, this DSP-enabled Class-D amplifier can drive low impedance 4Ω to 16Ω loudspeakers as well as high impedance 70V/100V transformer-coupled loudspeakers. The AMP-8-125 can accept eight balanced or unbalanced analog inputs and one stereo S/PDIF digital input and delivers either four low impedance stereo outputs at 125W per channel, or four 70V/100V mono outputs at 250W per channel.

For set-up, the RTI web GUI enables effortless browser-based configuration of the installed system. Its DSP configuration options include multizone setup, input mixing, priority and ducking, restriction, input and output EQ, S/PDIF output routing, high-pass filter, speaker presets, delay, Wall-S1 controller configuration, sine wave generator, and more.

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