Description
Description:
The AMP-8-125 power amplifier from RTI 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 peakers as well as high impedance 70V/100V transformer coupled speakers.
This amplifier with DSP 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 effortless set up, the RTI web GUI enables 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 much more.
Features:
- Eight analog audio source input channels balanced or unbalanced and one digital input S/PDIF
- Four Lo-Z stereo or eight Lo-Z mono output zones, four Hi-Z mono output zones or a mix of them
- Class D amplifier provides a robust and clear audio experience with 125W @ 4Ω or 8Ω per channel or 250W @ 70V/100V per channel
- Daisy chain multiple amplifiers and expand the number of zones by by distributing up to two audio inputs or zones
- Built in DSP allows for fine-tuning acoustic characteristics for each zone
- Easy configuration via LAN or WiFi
- IP and GPIO control options
- Free standing installation or rack mount with rack mount kit included
