## Long description

The AUDAC MTX48 audio amplifier Home Black 80 dB SNR 20-20000 Hz is a four-zone matrix amplifier designed for residential audio installations that require flexible input routing, microphone integration and reliable multi-zone distribution. It features two balanced microphone inputs with priority and optional phantom power, three-band tone control, four stereo line-level inputs and two additional wall panel inputs that accept line or mic signals. The unit supports both AC (100–240 V) and 24 V DC power, includes balanced line-level zone outputs on Euro-terminal blocks with accompanying RJ45 connectors for wall panels, and provides a front-panel rotary control per zone with LED indication. Network and automation compatibility is provided via a web-based interface, iPhone/iPad remote app and RS232 control. A built-in PFL loudspeaker enables pre-listening of channels without headphones.
Advantages
The MTX48 combines multi-zone routing with professional microphone handling and tone control to offer clean, consistent audio across four zones while maintaining a high signal-to-noise ratio of 80 dB. Compact 19-inch rack dimensions and a modest weight make it suitable for home AV racks. Dual-power capability (AC and 24 V DC) ensures continued operation during emergency power conditions. Integrated network control, RS232 compatibility and front-panel zone controls provide flexible management options for installers and end users.
Suitable for
 Multi-room home audio systems requiring independent zone control
 Small residential venues with microphone inputs and paging needs
 Integrations with home automation systems using RS232 or network control
 Installations where backup 24 V DC power is desired

How to use
Connect source devices to the stereo line-level inputs and attach microphones to the balanced mic inputs, enabling phantom power if condenser microphones are used. Use the front-panel rotary knobs to adjust zone levels and monitor status via LED indicators. Configure routing, tone controls and mic priority through the web-based interface or the iPhone/iPad Remote app; alternatively integrate control via RS232 into an existing home automation system. For wall-mounted control panels, connect to the RJ45 and corresponding Euro-terminal zone outputs. If required, switch to or provide 24 V DC backup power to maintain operation during AC outages.
Usage recommendations
For optimal performance, set three-band tone controls to a neutral position when initially tuning and then adjust to match room acoustics. Use balanced microphone connections and quality shielded cables for all critical audio links to preserve the stated 80 dB signal-to-noise ratio. When integrating with automation systems, test RS232 commands and web interface settings before finalizing installation to ensure reliable control across all four zones.
