The Opus 600 wireless system is recommended for stage performances and small installations (hotels, sports halls, churches etc.). It meets all technology and transmission quality requirements while still being very reasonably priced.

The Opus 600 wireless system is equipped with the automatic frequency setting function, has 16 pre-programmed UHF frequency settings and can be operated with up to 16 channels per frequency range (depending on environment and specific national regulations), simultaneously and with no interference. The latest true-diversity technology, pilot signal detection and adjustable squelch ensure reliable transmission and noise-free reception.


  • 1-channel true diversity receiver (UHF)
  • Rugged 9.5" metal housing
  • 16 pre-programmed UHF frequencies
  • AutoScan/ACT-function
  • PLL-synthesised technology
  • Adjustable Squelch This function allows you to make fine adjustments to the squelch. This is mostly necessary when several wireless systems are used simultaneously and there is interference on individual channels. In principle, the adjustment of the squelch affects the sensitivity; this also has a direct effect on the range of the system. Interference is eliminated by reducing the sensitivity of the channel affected by interference until only the main signal is being is received.
  • Pilot tone recognition
  • Removable antennas (TNC), antenna sockets with power supply (+8 V) for remote antenna amplifiers
  • Audio ouputs: 1 AF "Audio frequency" is a technical term for frequencies in the range of audible sound waves, i.e. frequencies from 20 to 20,000 Hz. In the context of wireless systems, you can simply refer to the audio signal.ouput (3-pin XLR male, balanced) and 1 AF "Audio frequency" is a technical term for frequencies in the range of audible sound waves, i.e. frequencies from 20 to 20,000 Hz. In the context of wireless systems, you can simply refer to the audio signal.output (6,35 mm jack, unbalanced), with MIC/LINE level switch Pocket transmitters: Switching between the Mic/Line levels makes it possible to use a pocket transmitter in a versatile manner.
