Portable Wireless System with PR 40 Divesity Portable Receiver, GB 40 Guitarbug Transmitter and MK GT 1/4" Phono Connection Cable


PR 40
The new PR 40 diversity portable receiver has been designed specifically for ENG and mobile video recording use. In conjunction with a wireless microphone, the PR 40 will solve any sound problem that may come up on location.

Place the wireless microphone and transmitter (e.g., C 417 + PT 40) near the sound source and mount the PR 40 on the camera. This puts both the microphone and receiver right where the action is, with full mobility and no cables getting in the way.

GB 40
The GB 40 guitarbug is probably the easiest way to turn a guitar, bass, or portable keyboard into a wireless instrument.

The FlexJack swivel jack plug will mate with any type of output jack and is spring loaded to hold the GB 40 securely against the instrument. In addition, the GB 40 is so small it is almost invisible and won't be in your way while playing. Since the GB 40 sits right on top of the instrument's output jack, the noiseless on/mute/off switch and gain control are always within easy reach. Integrated charging contacts allow you to charge the battery quickly and easily on the optional CU 40 charging unit, without having to remove the battery.
