6.8.2 Analog Audio Output
The RX will provide
Analog Audio Output
in the following
circumstances:
• When the RX is operating in Analog Mode.
• When the RX is operating in Digital Mode, and the MPEG
Decoder is configured to provide Analog Audio Output.
Analog Mode
In Analog Mode, the RX routes the received
analog signal through its analog FM demodulator. The RX’s
audio switching circuitry connects the output of the FM
demodulator to the Audio connector.
The analog demodulator provides either 2 stereo or 4 monaural
channels. All 4 circuits are balanced outputs (Live, Return,
Ground).
In Analog Mode, the RX Configurator and in the RX Monitor
Screens refer to these 4 analog circuits as Audio Channels 1, 2,
3, and 4.
The connections used for
Analog Audio Output
are described
in Table 6-2.
Digital Mode
In Digital Mode, the RX receives a digital signal
and routes the data to the COFDM demodulator and then to the
MPEG decoder. The RX’s audio switching circuitry connects the
output
of the MPEG Decoder to the Audio connector.
When configured for
Analog Audio Output
, the MPEG Decoder
provides either 2 stereo or 4 monaural channels. All 4 circuits
are balanced outputs (Live, Return, Ground).
In Digital Mode, the Audio channels are referred to as Audio A
and Audio B.
The connections used for
Analog Audio Output
are described
in Table 6-2.
Audio Cable Assembly
A prefabricated cable assembly is
available that splits the audio connections from the front panel
into 4 separate cables with XLR connectors. The 4 cables are
labelled Audio 1, 2, 3, and 4. One cable is included with each RX
ordered.
Should you need additional cables, the Vislink part number for
this cable is 907471-1.
The connections in this cable are as shown in Table 6-2.
