QSC MP-M40 – Digital Business Music and Paging Zone Mixer (8 In / 4 Out)

Product Overview

The QSC MP-M40 is a digital business music and paging zone mixer/processor for smaller commercial distributed audio systems. With 8 inputs and 4 zone outputs, it suits single-location retail stores, restaurants, corporate lobbies, fitness clubs, and similar spaces that need background music distribution and paging across up to four zones from one rack-mount processor. Onboard input and output processing, an automatic microphone mixer, and Intrinsic Correction loudspeaker voicings remove the need for separate DSP. Configuration is handled in the MP Install app, with day-to-day control through MP Manage and MP-MFC wall controllers.

Product Description

The MP-M40 provides four mic/line inputs and four line inputs (dual phono jacks summed to mono) for a total of eight sources, routed independently to four zone outputs plus a transformer-balanced music-on-hold output and a front-panel cue bus for auditioning. Every input includes high- and low-pass filters, 4-band parametric EQ, a gate, and a dynamics processor configurable as AGC or compressor. Any combination of inputs can feed any zone, and two inputs can be designated priority sources that duck program audio for paging. Output processing adds 1/3-octave graphic EQ, 12-band anti-feedback notch filters, comp/limiter, loudness, and up to 100 ms of delay, while a dedicated loudspeaker section provides factory Intrinsic Correction voicings for QSC loudspeakers plus a user 6-band parametric EQ with selectable Linkwitz-Riley or Butterworth filters. An integral stereo mixer with a gain-sharing automatic microphone mixer supports live reinforcement and conferencing. The MP-M40 supports up to eight MP-MFC wall controllers and pairs with QSC MP-A Series amplifiers for a complete system.

Frequently Asked Questions

How many zones and sources does the MP-M40 support?
It accepts 8 inputs (four mic/line and four line) and routes them independently to four zone outputs, plus music-on-hold and cue outputs.

Does it require a separate DSP?
No. Input and output processing — EQ, dynamics, anti-feedback filters, ducking, delay, and Intrinsic Correction loudspeaker voicings — is built in.

How is it controlled and configured?
Designers use the MP Install app to configure the system; staff use MP Manage and up to eight MP-MFC wall controllers for zone volume and source selection.

What amplifier should I pair with it?
QSC MP-A Series amplifiers (MP-A20V, MP-A40V, MP-A80V) are designed to complete an MP-M system. For larger installations, step up to the MP-M80 (16x8) mixer.

What is the warranty?
The MP-M Series carries a QSC 3-year warranty. For purchasing and integration questions, contact Creation Networks support.
