The accompanying figure shows the cable connections required for the satellite
LNB and TV monitor plus other (optional) connections that can be made from the
rear panel of your Headend Satellite Receiver. As many different equipment con-
figurations are possible, use the following information as a guide only. If you need
assistance to identify your specific equipment configuration needs, contact your
dealer/reseller or local service provider (see also “Connecting your system”).
Satellite antenna LNB and TV monitor connection
Connect the coaxial RF cable from the satellite antenna LNB to the receiver
SATELLITE jack
Connect a coaxial cable from the receiver VIDEO output jack to the TV monitor
VIDEO IN jack (optional), or to external headend TV modulator equipment
LNB power supply switch setting
Set the satellite LNB power switch (near SATELLITE connector) to OFF for using
the external LNB power source, or to ON for using the internal receiver LNB power
source (LNB power switch set to ON permits software control over the LNB power
supply output voltage from the receiver if switchable LNB connected)
Audio connections & level control
Unbalanced AUDIO: Connect A/V cables from the L (Left) and R (Right) receiver
AUDIO output jacks to the AUDIO IN jacks of your headend A/V equipment
(optional)
Balanced Audio: Connect separate conductors from the L (Left, +/-) and R (Right
+/-) receiver balanced audio output terminals plus the G (Ground) terminal to the
balanced audio/ground terminals of your headend A/V equipment
Level Control (Balanced Audio): If necessary, change the Left and Right preset
audio channel signal levels higher or lower (i.e., from unity gain) adjustable
±
6 dB by
rotating the potentiometers marked L and R (across from balanced audio output
terminals) clockwise or counterclockwise, respectively
Stereo/Mono balanced audio output switch setting
Set the MO/ST slide switch (near balanced audio output level control) to MO for
monaural audio output, or to ST for stereo audio output to your headend A/V
equipment
