A versatile multi-zone amp
The QSC MP-A80V offers a great deal of versatility in powering a large multi-zone system. FlexAmp technology allows this single amplifier to handle situations that would otherwise require multiple amps of different power levels. Its 1600-watt output can be assigned asymmetrically into its eight channels. And each channel features an individual attenuation knob and dip switches for 70V, 100V, and 4- or 8-ohm operation.
Asymmetrical power sharing
Each pair of channels delivers up to 400 watts of power, shared in any ratio. For example, channel one could send 300 watts to a pair of 8-ohm surface-mount subwoofers, while channel two uses most of the remaining 100 watts to power six QSC AC-C4T in-ceiling speakers tapped at 16 watts apiece. It's flexible enough to distribute power in a way that suits most commercial environments.

More details on the QSC MP-A80V
Overview: The QSC MP-A80V rack-mount, 8-channel amplifier is designed to provide a total of 400 watts of combined output power for each of the 4 pairs of output channels, for 4Ω, 8Ω, 70V, and 100V applications. Featuring Class-D topology, a switch mode power supply, Auto-standby, and active limiting and protection circuitry, the MP-A80V is the ideal solution for installed background music and paging applications.
FlexAmp: QSC's proprietary FlexAmp technology adds flexibility to your installed sound system by allowing each output channel to provide asymmetrical wattage amounts. This means with a total output power of 400 watts, one channel can be setup to deliver 100 watts while the other channel can deliver 300 watts, or any such combination. FlexAmp technology even lets you mix 4Ω or 8Ω connections on one channel with 70 or 100 volt operation on the other channel.
Inputs/Outputs: Eight 3-pin Euroblock (Phoenix) connectors provide the input channels, with each containing a signal +, -, and Ground, for either balanced or unbalanced connections. Four 4-pin Euroblock connector provides the 8 output channels, with each terminal accepting up to 12AWG speaker wire. The output connector features two built-in attachment screws for securing the plug to the back of the amplifier, preventing accidental disconnection.
- Rear Panel: Each of the 8 input
channels includes a rear-panel status LED that can display the following:
- Green: A signal is present on that channel.
- Orange: The input signal is near the clip point and the built-in Limiter circuit has been engaged to protect the output.
- Red: Channel is in Protect mode. Possible short on the output channel or thermal shutdown do to overheating.
- Off: Amp is in Standby mode.
- Front Panel: Front-panel
channel-status and Power LEDs provide the following information:
- Signal: Illuminates indicating a signal is present on that channel.
- Limiter/Protect: Lights to indicate Protect mode, Mute, or Limiter is activated. Off indicates system is working nominally.
- Power: Lights blue when unit is On, Amber when in Standby, and off when amp is powered completely off.
Input Level Adjustment: Each Input channel includes an Attenuation dial for adjusting the input signal level. Each dial has 11 attenuation levels ranging from 0 (+4dBu) to ∞ for total attenuation.
Output Configuration: Each of the MP-A80V's rear-panel inputs includes a 3-position DIP switch for selecting the type of output for each channel. Options include:
- 4Ω or 8Ω Selection
- 70V or 100V Selection
- HPF On/Off: When set to On, this applies an 80Hz high-pass filter to that output channel. This should always be set to On when using 70V or 100V full-range speakers.
Remote: The MP-A80V includes a rear-panel 5-pin Euroblock connector, providing two functions in one connector:
- Standby: Two Remote Standby contacts allow you to put the amp into and out of Standby mode from a remote location with an optional switch (not included). When the two pins are shorted together (i.e. making contact), the amp will go into Standby mode. Likewise, opening the contacts will take the amp out of Standby mode.
- Relay: The Remote Relay output provides a means to monitor the amplifier's operating condition with external equipment (not included).
Auto-Standby: The QSC amplifier will automatically go into Standby mode after 28 minutes with no signal input. When the signal returns, the amp will auto-ramp the signal back to its original level, avoiding an instantaneously loud signal.
Fan: The MP-A80V includes a built-in fan in the rear side-panel, providing forced air cooling through to the front air vent. Fan speed is thermally regulated.
