Stage/performance microphone Audac MPX88 — wired, RJ-45, 50–16,000 Hz, 45 dB sensitivity, 2 m cable, black

Audac MPX88 is a wired stage/performance microphone with an RJ-45 connection designed for live vocal and instrument pickup and for use as a paging station in combination with MTX series audio matrix systems. The MPX88 supports 8-zone operation when paired with an MTX88 matrix and provides a cardioid pipe-neck microphone element mounted in a modern enclosure with a real glass front panel and anti-glare coating. The unit includes integrated capacitive touch controls and blended status LEDs, a built-in chime tone before each announcement, and a fixed 2 m connection cable that can be extended over standard CAT5E twisted-pair cabling up to 300 m.

Advantages

The MPX88 combines a focused cardioid pickup pattern with a frequency response suited for voice and many instruments, covering 50–16,000 Hz and a sensitivity of 45 dB for reliable signal capture in live and installed scenarios. Its capacitive touch controls and concealed LEDs provide a sleek, low-profile appearance appropriate for office or design-conscious interiors. Integration with MTX series matrices enables zone selection, data bus feedback and cascading of multiple paging stations via a priority-configurable databus, simplifying multi-zone public address and announcement workflows.

Suitable for

• Live vocal and instrument pickup on stage or performance areas
• Paging and announcements in offices, retail or public buildings when paired with MTX matrix systems
• Multi-zone audio installations using MTX88 and other MTX matrices
• Design-conscious venues requiring a discreet, glass-front paging station

Key specifications

• Connectivity: wired with RJ-45 interface
• Microphone type: cardioid pipe-neck element
• Frequency response: 50–16,000 Hz
• Sensitivity: 45 dB
• Operating supply: 24 V DC with typical consumption 1.5 W
• Cable length: fixed 2 m (extendable to 300 m over CAT5E or better)
• Finish: black enclosure with glass front panel and anti-glare coating

How to use

Connect the MPX88 to the MTX matrix system using the RJ-45 cable. Use the capacitive touch controls on the glass front to select zones and operating modes; press and hold the push-to-talk (PTT) button during announcements. The integrated chime will sound automatically before each announcement. Adjust the pipe-neck microphone angle to optimise pickup. For longer cable runs, extend the connection with CAT5E (or better) twisted-pair cabling up to the supported maximum distance; ensure correct wiring and any required junction boxes for cascading additional stations.

Usage recommendations

Use the MPX88 with an MTX88 or compatible MTX series audio matrix and follow the matrix manufacturer’s wiring and configuration guidelines. Position the cardioid pipe-neck element toward the speaker’s mouth and avoid placing the microphone directly in front of loudspeakers to reduce feedback. When cascading multiple paging stations, employ recommended junction boxes and configure databus priorities to ensure proper control and announcement hierarchy.
