5. receiver that is paired with a transmitter with clothing noise reduction does not need to have any special software installed The CNR algorithm allows the transmitter to choose between its two microphones when audio from one microphone is noisy or unusually loud the transmitter cross fades to the other microphone The transmitter only transmits one channel at any given time This greatly reduces the occurrence of clothing noise in the final transmitted signal A transmitter with the CNR option has a two extra menu pages that are not found in a normal mono or stereo transmitter CLO page In the main menu there is a threshold adjust page labeled CLO The value of the CLO threshold can be adjusted from 00 to 99 Where a setting of 00 results in a very sensitive decision point at which the CNR algorithm decides to switch microphones A CLO setting of 99 reduces the tendency of the CNR algorithm to switch to another microphone If the transmitter is switching back and forth between microphones too often adjust the CLO setting to a higher number A setting of 99 is a good place to start BAX page In the extended menu pages there is a balance control labeled BAx where x is a number from 0 to 8 and 4 is the center note hold the FUNC key during power up to get to the extended menu pages This setting allows the user to balance out any differences in gain that might occur between a pair of microphones All microphones have
