Pre-Order Now: AMP-4-125 - 4 Channel 125W 8Ω, 2 Channel 70/100V 250W DSP Matrix Amplifier
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 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).
2 Sources / 4 Channels
Two analog audio source inputs (balanced or unbalanced) and one digital input.
2 Zones
Choose between standard stereo zones or a 70V/100V sound system.
Full Matrix
Distribute two audio source inputs to two zones, with the ability to expand to additional zones by daisy-chaining multiple AMP-4-125 units.
Powerful Stereo Output
Delivers 125W power output per channel for stereo zones.
Powerful 70V/100V Output
Provides 250W per channel for 70V/100V zones.
Built-In DSP
Easily configure and optimize DSP and matrix settings through the intuitive web user interface.
Ultra-Efficient
Cool Power® Class D amplifier technology ensures efficient heat dissipation and low power consumption.
Audio Source Versatility
Supports a combination of analog and digital audio sources for flexibility.
Control
Seamlessly integrate with RTI or third-party control systems via IP, or use GPIO control for volume, standby, mute, or trigger functions.
