The »Pro Loop DCCplus« feeds inductive audio signals into large loops

The Pro Loop DCCplus proves to be the ideal solution for supplying inductive audio signals to event and meeting rooms.

Each of the two XLR(F) inputs can be configured as LINE (symmetrical) or as microphone input (asymmetrical).

The equipment provides an output of up to 12 A RMS and guarantees secure transmission of audio. The Automatic Gain Control hereby ensures good sound reproduction at a constant field strength and high stability.

For standard and low overspill supply

Beyond the standard application, the Pro Loop DCCplus is also suitable for setting up low overspill loop systems. This requires two Pro Loop DCCplus devices. The devices are connected via the integrated jack sockets “Slave In” and “Slave Out”.

  • Simple and safe handling
  • High output current: 12 A RMS
  • Main transfer switch 115 / 230 V AC
  • Active protection against short circuits
  • Two XLR(F)-sockets configurable as Microphone input (amplifier setting, phantom feed) or LINE-input (amplifier setting)
  • 100-V-priority input for the connection of ELA systems
  • Separate treble/bass regulation
  • Display of loop current
  • 6.3-mm-headphone socket for monitoring the audio output
  • Control to reduce metal losses
  • Suitable for the set-up of low overspill systems
  • 19” rack casing
