Lectrosonics Pro 4 Channel - Manual (Page 2)

INTRODUCTION
The PRO 4 CHANNEL system is a high quality, multi-channel wireless microphone system designed for sound
stage, studio, and theater applications. Multi-channel problems such as interaction of receivers, intermodulation
and desensitization, etc. have been eliminated through creative engineering and superior design. The integral DM4
distribution module provides convenience of operation from a common antenna system and power supply without
degrading the performance of the receivers. In fact, the additional RF filtering in the DM4 module actually improves
the already outstanding selectivity of the R185 receivers.
The PRO 4 CHANNEL system is available in two versions Standard and Diversity. The Standard version
consists of a DM4 RF/Power distribution module and a DC power supply installed in a 19" rack mount. The
Standard version is available with up to four R185 wireless receivers and companion transmitters, or by itself to
combine existing R185 receivers.
The Diversity system consists of a DM4D RF/Power distribution module and up to four DR185 wireless receivers
and companion transmitters.
