Description
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 Glensound's 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.
Features:
- 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
