A 1u 19” rack unit containing 4 separate 4 wire/IFB circuits.  The GS-FW024 MKII is the next generation on from the very popular original GS-FW024 and is one of our top of the range of extensive 4-wire talkback units.  Glensound has been designing and making 4-wire talkback units for more than 35 years and the GS-FW024 MKII builds on past experience to provide a highly reliable and comprehensively specified unit which is also hugely versatile and is ideal for the communication hub of small OB vans and small studios.

  • 4 outgoing and incoming talkback circuits
  • 1 incoming 'Programme' circuit
  • Presence LEDS indicate when an incoming talkback circuit receives audio
  • Internal front panel microphone and XLR for external microphone
  • Individual gain controls for both microphones
  • Glensound ‘Referee’ compressor/ limiter circuit on mic amps
  • Illuminated talkback keys can easily be programmed to alter operation mode (latching, momentary, latching & momentary (intelligent lever key))
  • All 4-wire circuits have input & output gain controls
  • 4 wire inputs can be looped to 4-wire outputs (IFB)
  • PGM input can be routed to 4-wire outputs
  • PGM inputs & IFBs can be mixed or cut when talkback keys are operated
  • Front panel switches for routing PGM & IFB & selecting mix/cut operation
  • Talkback groups can simply be defined
  • Mains powered 100-250 VAC
  • Front panel speaker and headphone jack (cuts front panel LS)
  • Balanced external LS output (0dB)
  • Front panel LS/Headphone volume control
  • Transformer balance outputs
  • Highly reliable electronic 'transformer' inputs
  • Power ON LED
  • All audio inputs & outputs on XLRs
  • Lazy mic output (permanent un-switched)
  • Loop inputs for remote operation of talkback keys
  • Loop outputs for red light switching/ external LS dim etc from talkback keys
  • Large labelling points for designation of audio circuits
