Figure 1- Transmitter Inputs and Adjustments
CD players, and PC sound cards have a single miniature (3.5mm)
stereo phone jack (as opposed to separate RCA phono-type jacks).
To connect any of these to the transmitter, use the supplied adaptor
in conjunction with a phono cable to make the connection. Left
and right stereo inputs may be connected to the red and white
phono inputs. The output from the receiver will be monaural
however.
Mic Input
A microphone input may be used as well. Connect using either the
balanced XLR or 3.5mm connectors.
Mic Ducking Switch (rear panel)
ON: By switching the ducking switch to ON, the line input audio
will be muted when the microphone is used. When microhone
input is no longer detected, the line audio will resume.
OFF: Mic audio will be mixed with line audio.
Mic ALC Switch
ON: Prevents over-modulation distortion due to excessive mic
level.

converter’s 2.1mm plug into the
DC INPUT
