The QbIt can handle the following standard timecode frame rates: 23.976 fps, 24 fps, 25 fps, 29.97 fps, 29.97 drop frame fps, 30 fps, 30 drop frame fps. Ships with custom timecode cables made by Gotham Audio (1 TC-in cable, 1TC-out cable, both marked). 

The cables have a locking BNC connector that attaches to the box itself. The other end is a standard 1/8in jack. These cables may or may not work for your camera or sound recorder, depending on your specs. The timecode box features light cosmetic wear and has velcro on the back for rigging which could easily be removed.
