OSD MX1680 16-Channel 8-Zone Multi-Room Power Amplifier
The OSD MX1680 16-Channel 8-Zone Multi-Room Power Amplifier delivers exceptional high-density multi-room audio distribution, powering up to 8 discrete stereo zones from a single compact 2U chassis. Delivering 80 watts RMS per channel into 4 ohms (50 watts RMS into 8 ohms) across all 16 channels, and bridgeable to 160 watts per zone at 8 ohms, the MX1680 features high-efficiency Class-D digital architecture, dual global bus routing, independent channel gain controls, and signal-sensing auto-on circuitry.
If you want to know what 16-channel amplifier delivers high-density multi-zone sound for luxury estates and commercial facilities without overheating equipment racks, how bridging adjacent channels provides high-power output for outdoor audio zones, or how dual global bus routing simplifies complex distributed sound installations, the OSD MX1680 is the ideal choice. Professional integrators rely on the MX1680 for its clean power delivery, flexible input matrix, and rock-solid reliability.

High-Density 16-Channel 8-Zone Audio Distribution
Consolidate up to eight independent stereo listening zones into a single 2U rack space, eliminating equipment rack clutter while providing 80W RMS per channel at 4 ohms across all 16 channels with audiophile precision.
Bridgeable Outputs for Dynamic High-Power Zones
Easily bridge any of the 8 stereo zones to deliver 160W into 8 ohms, providing ample headroom for power-demanding landscape speakers, outdoor patio arrays, or high-performance architectural listening rooms.
Dual Global Bus Matrix Routing & Local Inputs
Two shared global bus inputs allow you to distribute central audio streamers across all rooms, while dedicated local RCA inputs per channel pair enable local room source playback, with buffered loop outputs for system expansion.
Thermal Efficiency & Intelligent Auto-Sensing
Advanced Class-D digital circuitry generates minimal heat, allowing cool, fanless operation in standard 19-inch equipment racks. Signal-sensing Auto-On and 12V trigger in/out automate system activation.
