Description
The RTI-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 RTI-AMP-8-125 can accept eight balanced or unbalanced analog inputs and one stereo S/PDIF digital input and delivers eight low impedance mono channels (or four low impedance stereo zones) at 125W per channel, or four 70V/100V mono channels 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:
RTI-AMP-8-125, power cord, 6-pin Phoenix input connectors (4), 4-pin Phoenix output connectors (4), 8-pin Phoenix GPIO socket connector (1), adhesive rubber feet (4)
8 inputs, 1 digital input / 8 outputs
Eight analog audio inputs (balanced or unbalanced) and one digital input. Outputs configurable as eight Lo-Z or four Hi-Z.
8 Zones
Choose between four standard stereo zones, eight mono zones, four 70V/100V zones, or any mix of Lo-Z and Hi-Z zones.
Full Matrix
Distribute four audio source inputs to four zones, expandable to more zones by daisy-chaining multiple RTI-AMP-8-125 units.
Powerful Stereo Output
125W power output per channel for stereo zones.
Powerful 70V/100V Output
250W per channel for 70/100V zones.
Built-In DSP
Configure and optimize DSP and matrix settings with the intuitive web user interface.
Ultra-Efficient
Cool Power® Class D amplifier technology ensures efficient heat dissipation and low power consumption.
Audio Source Versatility
Use either analog or digital audio sources or a combination of both.
Control
Control the unit with an RTI or 3rd party control systems via IP or use the GPIO control for controller for volume, standby, mute or trigger functions
