TRIM OUT
Installation
Trim Out
input to receive TV antenna signals, which is best used
in combination with a video amplifier.
To install the 3x4 Multi-Switch module in the SMC:
• Align the mounting pin plungers with the mounting
holes in the back panel of the SMC (the module must
be mounted horizontally)
• With the mounting pin plungers in the “out” position,
press the unit into the grid in the desired location
• Final setting is made by pushing the plunger head in
to lock it in place
• Attach the satellite cable (RG-6 “F” type) connector to
either of the LNB input ports (marked “LNB-A” or
“LNB-B”)
• Attach the RG-6 “F” connector from the TV (terrestrial
or CATV) antenna to the input port (marked “ANT”)
✍
Take Note: When using the 3x4 Multi-Switch in combi-
nation with a TV antenna, a video amplifier is recommended
to boost the outgoing signal.
• Attach the RG-6 “F” connectors from the satellite re-
ceivers (in up to four room locations) to the output
ports (marked “Receivers, 1-4”) on the Multi-Switch
• Cap any unused input or output connections with 75-
ohm termination caps
✍
Take Note: When combining the incoming TV antenna
signal with the incoming satellite signal, it is necessary to
use a diplexer to separate out signals before connecting the
the satellite receivers.
9.6 Multi-Room Stereo Sound
Application
In the Leviton Structured Media concept, multi-room
distributed stereo is also centralized in the Structured
Media Center for manageability and reliability. Three
pair of speaker wires (left and right) and 12VDC power
need to be run from the stereo system or entertainment
center to the SMC; the Audio Bridging Module will dis-
tribute this stereo signal to up to 6 locations or “zones.”
✍
Take Note: Many audio/video receivers with built-in sur-
round have up to 5 speaker channels. While any full-featured
model will have a provision for connection to an auxiliary,
stereo-only speaker pair, it is important to locate and use
only the amplifier outputs dedicated to powering remote
speakers. This might also require activating the A/V receiv-
er’s “multi-room/multi-source” switching functions.
Consult the Owners’ Manual supplied with the A/V receiver
for complete information.
9.6.1 Multi-Room Considerations
Leviton’s Audio Bridging Module and Volume Controls
provide up to 6 parallel speaker left/right pair connec-
tions from a single stereo pair left/right input. Before
connecting six pairs of speakers, you’ll need to know
the impedance ratings or levels of the speakers you’re
working with.
