[QUOTE="Daniel Postilnik, post: 10371, member: 184"] In one of the install I systems I work with (it's a fitness studio), the vendor has installed an xlr output in the wall that is a direct split from the wireless mic receiver for that room, located in a rack in a different room. The wiring is such that a cable from the RF mic receiver in the rack goes to a phoenix connector input on a DSP a couple of rack slots below it, and the split is achieved by running a line from that same phoenix connector all the way out to the xlr output on the wall. So the phoenix connecter has one cable in and one cable out carrying the same signal. When we tested this system by running a cable from the wall output into a camera, I detected what sounded like a 6dB drop in signal in the level of mic being piped to the room. The drop occurred as soon as we plugged the cable into the camera. Is there a principle by which splitting a signal cable drops the signal level by a specific quantity? Is there any kind of in-line pre-amp that could be used on the split line to offset the signal level drop? [/QUOTE]
