Separate controls are provided at the capsule for bass, mid and treble boost or cut. This aids in matching the microphone to other mics already in use. An attenuator is also provided for occasions when an exceptional amount of headroom is required. The main level control is in the battery compartment along with defeat switches for the operating LED and outer control switches. There is a small magnetically held door on the side of the microphone, beneath which are the frequency adjustment controls for the transmitter.
Diversity is the term applied when more than one antenna or receiver is being used.
The main propose of this type of design is to improve reception by minimizing multipath drop-outs. What makes the UDR200C different from other diversity receiver systems is that rather than switching to another antenna, or switching to another receiver, it actually blends the outputs of two receivers in a ratio controlled by the comparative RF inputs of both receivers. This process eliminates the switching drop outs sometimes heard in other designs, and greatly improves the signal to noise ratio. Another impressive feature of the UDR200C is the dual-band compander. Each channel's attack and release times are optimized for its respective frequency range.
