Part #: S8411
Description: The GX-4 and GX-8 series of combiner/amplifiers is used for combining multiple IEM transmitters and/or wireless intercom transmitters into a single antenna. It may be fed RF signals from Shure, Telex, Lectrosonics or Sennheiser IEM transmitters or from a wireless intercom such as a modified Telex BTR-800. An Automatic Level Control allows it to accept RF input levels of 20 to 100 mW across the 470 to 698 MHz radio band. Each input contains its own discreet RF amplifier and proprietary ALC circuits. The signals are individually amplified and then combined to produce 250 mW of RF output for each channel at the antenna output port (250 mW is the maximum power allowed by the FCC in the UHF band). This can be fed to single antenna and often, numerous separate antennas for each transmitter can be eliminated. A High Power/Low Power mode controlled from the front panel allows for using a power level appropriate to the venue, and a front panel display shows the operating frequency for each transmitter as well as an RF power indication. On request power output cables for popular IEM transmitters can be fitted to the GX unit which will eliminate the clutter of wall-wart power supplies used with most IEM transmitters.
