About this product
The MX880 is a 4-zone, 8-channel Class D amplifier for residential and commercial distributed audio systems that need reliable power across multiple rooms. Each channel is rated at 80W into 4 ohms and 50W into 8 ohms, and every zone includes a bridge switch that combines both channels into a single 160W output at 8 ohms for larger spaces or 70V-style long runs. Independent zone control with global and per-zone triggering lets each area run its own source through the zone line input, or follow a shared bus feed through Bus In 1 and Bus In 2. Signal auto-sensing powers the amplifier up when audio is detected and down when it stops, reducing standby consumption in always-on installations. Protection circuitry guards against thermal overload and short circuits. The slim 2U chassis is rack mountable with hardware included, runs cool thanks to Class D efficiency, and provides individual output level controls plus detachable speaker terminals accepting up to 14AWG.
Four Independent Stereo Zones, Eight Channels
Eight channels arranged as four stereo zones deliver 50W RMS per channel at 8 ohms and 80W RMS per channel at 4 ohms, with 160W maximum per channel. Each zone operates independently with its own level control, so background music, paging and entertainment can run in different areas from one chassis.
Bridgeable Zones for Higher Output
A bridge switch on each zone internally combines both channels into a single connection using the left input, producing up to 320W maximum at 8 ohms. This gives flexibility for larger rooms, longer speaker runs or higher-demand areas without adding a second amplifier to the rack.
Bus Inputs for Shared or Independent Sources
Each zone provides a line input plus Bus In 1 and Bus In 2 with pass-through outputs, so zones can share a common source or run separate ones. Paired with an audio distribution preamp or matrix processor, each zone independently selects among several sources through its own line input.
Auto-Sensing and Global 12V Trigger
Signal auto-sensing powers the amplifier up when audio is detected and shuts it down when the signal stops, cutting idle draw in always-on installations. A bus global 12V trigger plus per-zone triggering allows integration with control systems that need coordinated or independent zone startup.
Slim 2U Rack Chassis with Protection Circuitry
The 16.81 by 3.46 by 16.41 inch chassis mounts in a standard rack with included hardware and runs cool on efficient Class D amplification. Protection circuitry guards against thermal overload and short circuits. Detachable speaker terminals accept up to 14AWG. 90dB A-weighted signal-to-noise, 2-year warranty.

The MX1280 GEN2 is a 6-zone, 12-channel Class D amplifier for residential and commercial distributed audio systems requiring reliable power across many rooms. Each channel supplies 80W into 4 ohms and 50W into 8 ohms, and every zone includes a bridge switch that combines both channels into a single 160W output at 8 ohms. The GEN2 revision adds front-panel on and off buttons for each stereo zone, so unused areas can be shut down individually to reduce power consumption without touching the rear panel or a control system. Independent zone control with global and per-zone triggering lets each area run its own source through its line input, or follow a shared feed through Bus In 1 and Bus In 2. Signal auto-sensing powers the amplifier up when audio is detected and down when it stops. Protection circuitry guards against thermal overload and short circuits. The slim 2U chassis is rack mountable with hardware included and pairs with the CONTROL12 for a complete distributed audio setup.
The SMP500DSP is a Class D mono subwoofer amplifier built for higher-wattage passive subwoofers such as in-wall models that require external power. It delivers 400W RMS and 800W peak at 4 ohms, or 250W RMS and 500W peak at 8 ohms, in a rack-mountable 1U chassis. A front-panel variable high-cut filter adjusts from 30Hz to 150Hz, routing higher frequencies to the main speakers so the subwoofer concentrates on low-frequency content. Additional front-panel controls cover phase and volume, and the amplifier includes an adjustable gain and volume limiter to protect woofers from overdrive. Turn-on options include music sensing, manual on or 12V trigger. Input choices cover signal-level and speaker-level connections plus LFE, with speaker pass-through outputs for older and newer systems alike. Frequency response spans 10Hz to 150Hz with a 95dB signal-to-noise ratio and air cooling. The power supply is switchable between 115V and 230V. ETL and CE rated with a 2-year warranty.
