The AUDAC MTX88 routes and mixes audio from multiple sources—such as microphones, music players and wall panels—to up to eight independent zones. Each zone can have its own volume, source selection and EQ, making it perfect for venues that need different sound in different spaces.
Key features of the MTX88 8 zone audio matrix
The MTX88 packs professional audio processing and control into a single, installer-friendly unit.
- 8 × 8 audio matrix system: Route any input to any of the eight stereo zone outputs.
- 2 balanced microphone inputs: XLR connections with phantom power and priority function for clear paging.
- 4 stereo line-level inputs: Connect CD players, tuners, media players or streaming devices via RCA.
- Wall panel integration: Additional line and mic inputs available via optional wall panels for each zone.
- Three-band tone control: Per-mic EQ and output EQ for finely tuned sound in each zone.
- Built-in PFL loudspeaker: Pre-listen to any channel from the front panel without headphones.
- Flexible control options: Front panel, wall panels, RS232, TCP/IP, iPhone/iPad apps and integrated web interface.
- Emergency-ready: 24 V DC input keeps the system running on backup power if mains fail.
- Low power consumption: Only 12 W, ideal for 24/7 commercial installations.
