Simple dry box - for use with a tracking camera on a dolly where the cameraman needs to talk to a grip (usually with an open mic), but also need s to hear production talkback and have a reverse circuit.

Place the dry box at the end of the RTS beltpack feed to isolate Channel 2 and replace it with a new unpowered channel for grips.

The advantage is that the Camera Opeartor/Grips Channel 2 chit-chat and noise picked upoff the open mic will only go back to as far as the DRY Box and cannot crosstalk onto production on channel 1 and will therefore not be heard in the gallery! Ths avoiding  the director going mad! and not hearing anyting he shouldn't on his performance from the Grip!

Use it at concerts and POP videos with a tracking camera on a doll.

If you dont have RTS intercom you will require a PS15 power supply , SSA324 for interface to Production Talkback,  Dry Box, 2 Beltpacks and 2 Headsets and some XLR audio cable.   You will need 1 dry box per tracking camera with Grip.
