Product Description

An inconspicuous, wireless instrument transmitter and diveristy receiver for more freedom on stage.

With the SR 40 FLEXX Receiver and GB 40 FLEXX Guitar Bug Transmitter combo you can concetrate on your guitar, bass, or portable keyboard performance without worrying about tripping over wires or losing sound quality as you work the stage.

SR 40 FLEXX Receiver

The SR 40 FLEXX is a stationary diversity receiver for use with all WMS 40 FLEXX and Microtools Series transmitters (sold separately). It features a half-rack case for mounting in a 19″ rack. Operating in the 660MHz to 865MHz UHF range, the SR 40 FLEXX provides three selec- table, quartz-stabilized carrier frequencies within the 3MHz-wide frequency band. This allows you to select a different frequency if one of the three frequencies does not provide adequate signal quality. The frequencies have been factory preset to make sure you can set up a multichannel system with up to three channels with three kits operating in the same frequency band. Using a suitable combination of kits operating in different frequency bands you can even use up to nine channels simultaneously.

The SR 40 FLEXX uses two antennas in order to receive the transmitter signal at two different spots. The diversity electronics will automatically activate the antenna that delivers the better signal. An adjustable squelch will mute the receiver if the received signal is too weak so the related noise or the self-noise of the receiver will not become audible when the transmitter is switched OFF.

GB 40 FLEXX Guitar Bug Transmitter

The GB 40 FLEXX Guitar Bug is a WMS 40 microtools Series miniature transmitter that has been specifically designed for electric guitars and basses but is also suited for keyboards.The transmitter features a permanently attached, swiveling 1/4″ jack plug that allows you to plug the transmitter directly into the output jack of your instrument. A built-in spring presses the transmitter against the instrument to hold it securely in place. The bottom of the transmitter is fitted with a soft plastic pad that will leave no trace on the instrument. The supplied Velcro pads allow you to attach the transmitter even more firmly to the instrument. Operating in the 660MHz to 865MHz UHF range, the GB 40 FLEXX provides three selectable, quartz stabilized carrier frequencies within your specified 3MHz-wide frequency band and uses a permanently attached flexible antenna.
