QSC MP-A40V – Multi-Channel Commercial Music and Paging Amplifier

Product Overview

The QSC MP-A40V is a four-channel commercial music and paging amplifier designed for business music and distributed audio systems that need flexible per-zone power. FlexAmp technology lets each pair of channels share up to 400 watts in any ratio, so output can be matched to actual zone loads without over-specifying amplifier hardware. Each channel independently drives 4 Ω, 8 Ω, 70 V, or 100 V loads, supporting mixed low-impedance and distributed speaker systems. The MP-A40V pairs with the QSC MP-M Series zone mixers for a complete commercial audio solution.

Product Description

The MP-A Series builds on QSC’s long history of amplifier reliability while emphasizing efficiency and low total cost of ownership. The MP-A40V provides two channel pairs, each sharing 400 watts of combined power (800 watts total) distributable in any ratio across the two channels of a pair — for example, driving ceiling speakers in a restroom from a small share of one channel while sending the bulk of power to the main dining-room speakers on its partner channel. Class-D output circuitry and a switchmode power supply keep the four-channel amplifier in a single rack unit with low heat and power draw. A DIP-selectable load mode sets each channel to 4 Ω, 8 Ω, 70 V, or 100 V, and a switchable 80 Hz high-pass filter is available per channel. Power-saving auto-standby engages after 28 minutes of inactivity with seamless auto-ramp when signal returns, and a remote standby input plus an amplifier status output support integration with building and life-safety systems. The MP-A40V is designed to work directly with the MP-M80 and MP-M40 zone mixers.

Key Features

• Four channels with FlexAmp — Two channel pairs each deliver up to 400 W (800 W total) split in any ratio between the two channels.
• Per-channel load selection — Each channel independently drives 4 Ω, 8 Ω, 70 V, or 100 V loads.
• Class-D efficiency — Class-D output and a switchmode supply provide high efficiency and low operating cost in a 1RU chassis.
• Selectable 80 Hz high-pass filter — Available per channel to protect small speakers and tighten low-frequency response.
• Power-saving standby — Auto-standby after 28 minutes with seamless auto-ramp, plus a remote standby input.
• Amplifier status output — Remote fault/status reporting for monitoring and life-safety integration.
• MP-M Series integration — Designed to pair with QSC MP-M40 and MP-M80 zone mixers for a complete system.

Typical Applications

• Commercial meeting space — Multi-zone background music and paging amplification.
• Multi-purpose room — Mixed 70V/100V and low-impedance speaker drive from one chassis.
• House of worship — Distributed audio across lobbies, classrooms, and overflow zones.
• Training room — Dedicated amplified zones within a larger facility.

Frequently Asked Questions

How does FlexAmp power allocation work?
Each channel pair shares 400 watts of combined power that can be split in any ratio between its two channels, so output matches each zone’s actual load instead of being fixed.

Can it drive both 70V/100V and low-impedance speakers?
Yes. Each channel is independently set to 4 Ω, 8 Ω, 70 V, or 100 V, so one amplifier can mix distributed and low-impedance zones.

Does it integrate with QSC mixers?
The MP-A40V is designed to work with the QSC MP-M40 and MP-M80 zone mixers to form a complete business music and paging system.

How does standby affect paging?
Auto-standby engages after 28 minutes of inactivity and ramps back up seamlessly when signal returns; a remote standby input is also provided.
