ORION LC Installation and Operations Manual
Using a Microphone
A microphone may be plugged into the ‘Line In’ connector on the receiver
Unit. There are two ways of setting up a microphone:
1. Connect the transmitter’s ‘Line Out’ connector to the microphone input
(red) on your sound card using a standard 3.5mm stereo audio cable.
The sound card should then be set up to provide additional amplification
(+20dB). This is the preferred connection method.
2. Alternatively, the Remote Unit itself can provide microphone
amplification. To set this, open up the Remote Unit and locate the
jumper labeled ‘MIC’ on the daughterboard. Connect this jumper across
the pins. The Local Unit’s ‘Line Out’ connection should then be wired to
‘Line In’ (blue) on your sound card. If your microphone is already
amplified, follow the second method but DO NOT install the
amplification jumper in the Remote Unit.
