GMW-U4 provides four channels 32 selectable UHF frequencies in both the receiver and transmitter. This system contains an GMW-U4 four channels receiver, 4 GMW-T gooseneck transmitters.
It can work at any selectable frequencies, making it eminently suitable for where multiple wireless gooseneck conference microphones need to be used simultaneously. Specifically, it offers 32 different operating frequencies within each of eight bands (500MHz~880MHz), allowing up to six different gooseneck transmitters can be used simultaneously in one band. So 48 transmitters can be installed at one place.
The UHF and selectable frequencies means more clear voice, more reliable signal and better capability of anti-jamming. The design is fully consider for the applications of conference.
The system's compact half-rack receiver features a large front-panel LCD display on the front panel and a comprehensive feature set. The gooseneck transmitter is also equipped with LCD display, which can display frequency, battery information and signal strength.
The system includes patent-pending PLL synthesized VCO circuitry in the transmitters along with SAW (Surface Acoustic Wave) filters in the receiver. The system also includes built-in Noise Squelch circuitry.
FEATURES：
LCD display indicates Channel, Audio Level/RF Level, Diversity A/B antenna and Mute.
SAW (Surface Acoustic Wave) filters for discriminating wireless reception.
Built-in Noise Squelch circuitry mutes system wide-band noise.
Balanced XLR output and 1/4" output.
Compact half-rack receiver design with optional rack-mount kit.
Transmitters feature PLL synthesized VCO technology to eliminate spurious emissions in multi-user venues.
Transmitter features frequencies, battery life , signal intensity indicator, high/low RF output and full complement of controls.
Tuned molded antennas for enhanced reception.
1.5VDCx2 battery operation.
