[QUOTE="Tim Perry, post: 65476, member: 94"] Re: Upgrading Wireless System, choices... Marc, the PGX-D handheld has a 2 position attenuator assessable by unscrewing the capsule. it can be set for 0 or -10 dB. With the -10 setting a loud (screaming) vocalist will push it into distortion. The unit I encountered had a SM58 capsule. It may work just fine for less demanding applications. There are several technical issues to consider in your situation. One is proximity to the receivers: it is possible to be too close. with multiple units on you may experience fundamental overload and/or inter-modulation problems. Another issue is frequency bands and external interference. As you move from city to city there might be a TV station transmitting on the band you are occupying. Do you employ an antenna combiner or do you have a "forest" of antennas at the receiver location? A 'good' antenna combiner may significantly improve operational reliability in your case. This is NOT a bunch of T connectors or even cable TC splitter/combiners. Take a look at the Shure UA844 (it only does 4 but it a start) Personally I favor the Shure ULX as the best comprise between what I can afford and the quality I seek. Another factor to consider is the 'compnadering' (compression / expansion ) scheme each system uses. This is used to get FM like sound from a narrow band frequency channel. Not so great usually for percussion. I have had a guitarist who could hear the delay and /or artifacts after rewiring a LAV to an instrument 1/4" connector. My strongest recommendation is to discuss you needs with an applications engineer of whichever company you settle on.
