QSC 400W FlexAmp Hi/Lo-Z 8-Channel Amplifier MP-A80V, 8x 200W Power, Highpass Filter Per Channel
Eight zones, one slim rack unit.
The QSC MP-A80V is an 8-channel Class-D amplifier with 1600W RMS output. It drives 4 Ohm, 8 Ohm, 70V or 100V speaker lines for background music and paging in a 1U chassis.

Multi-zone sound shouldn't fill your rack.
Business music and paging often means many speaker zones with different loads. Separate amps take up rack space and add cost.
Flexible power for every zone
The MP-A80V pairs flexible power sharing with per-channel controls and power saving.
FlexAmp power sharing
Each pair of channels can deliver up to 400W total power, in any ratio.

RMS output power
Delivered across 8 channels in a 1U chassis.
Load selector per channel
Choose 4 Ohms, 8 Ohms, 70V or 100V on each channel.
80 Hz highpass filter
A selectable 80 Hz highpass filter is offered on each channel.
Auto-standby saving
Auto-standby starts after 28 minutes, with seamless auto-ramp when signal returns, plus a remote standby input.
