Overview

A staple of the Redback range since we first started, the 30W amplifier meets the requirements of small to medium public address installations. Features push to talk (PTT) auxiliary muting, three combined balanced microphone / stereo line inputs, tape out, and separate bass and treble controls. Offers a wide scope of installation applications, including schools, public halls, workshops and sporting complexes. Output may be 100V line or low impedance (8 - 16Ω) speaker loads. This unit features thermal overload shutdown, over current and short circuit protection.

Vox muting: The VOX circuit allows telephone paging via line input one or two (selectable internally). When paging via the telephone, all other line inputs are muted (ie. background music). Features variable sensitivity and time delay settings.

Features:

  • 19" rack system mountable.
  • Push to talk (PTT) muting on microphone 1.  
  • Balanced microphone inputs.  
  • VOX muting circuit.
  • Stereo line inputs & tape output.
  • Bass and treble tone controls.  
  • Output terminals for 100V line and 8 - 16Ω loads  
  • Over-voltage, over current, thermal run-away and short circuit load protection.
