Analog Audio Interface
The analog audio option supports bidirectional
stereo audio transmission, at near CD quality
. The audio
interface is a 'line level' interface and it is designed to transmit the signals of a sound card (or other 'line level'
device), as well as to allow the connection of active speakers to the Receiver unit. Stereo audio can be
transmitted in each direction at the same time.
Connecting a microphone:
Connect the microphone to the
Audio
input of the Receiver unit. There are two ways to establish this
connection:
The output of the Transmitter Unit is connected to the microphone input of the sound card (red). Adjust
the sound card to provide an additional amplification (20 dB).
The output of the Transmitter Unit is connected to the audio input of the sound card (blue). Choose this
connection if the microphone has its own pre-amplifier.
The Receiver Unit can also supply pre-amplification of a microphone. Open the Receiver Unit, locate the
MIC
jumper on the audio board and close the pins.
