Matrix preamplifier 4 zone FM DAB Bluetooth 1U - RONDSON RON-02782

The RONDSON MX-404 is a four-channel matrix preamplifier with four inputs and four outputs, built to drive up to four audio zones independently. Each path routes inputs to dedicated outputs with separate volume control and its own level indicator.

I/O includes two Combo XLR / 6.35 mm jacks configurable for microphone or line with phantom power, an XLR microphone input (Input1), a stereo RCA / Euroblock line input, and a front AUX input on a 3.5 mm mini-jack. All four line outputs use Euroblock connectors. The integrated media player provides FM / DAB tuning, a USB port, and Bluetooth; an RJ45 connector links to a Call Station, and an alarm contact operates at 24 V.

Power accepts 115 - 230 VAC or 24 VDC; compact 1U rack dimensions and low weight keep installation practical. Audio performance keeps total harmonic distortion below 0.03% and signal-to-noise above 75 dB on microphones and above 85 dB on line and AUX. Hotels, conference rooms, schools, and sports centres benefit from multi-zone control, broad connectivity, the built-in player, flexible AC or DC supply, and strong sonic figures.
