Speaker Connections
(BASIC/ADVANCED/EXPANDED)
SPEAKER PHASING: TO OBTAIN STABLE IMAGING AND FULL BASS RESPONSE, IT IS IMPERATIVE
THAT STEREO SPEAKERS BE CONNECTED "IN PHASE" WITH EACH OTHER. YOU CAN VERIFY THIS
AS FOLLOWS:
1. If the "+" (positive) and "–" (negative) terminals on your speakers are correctly marked, and visible, and you
have wired the system with the positive speaker connector on the rear of the MRC44 Controller/Amplifier
connected to the positive connector on the speaker and the negative speaker connector on the rear of the
MRC44 Controller/Amplifier connected to the negative connector on the speaker, then the system will be "in
phase". No further action is required. Most manufacturers identify the positive terminal with a red binding
post, a "+" sign, or a red dot.
2. If you are unsure of the markings, you can verify the phasing. Using a mono sound source, such as AM
radio, alternately reverse the leads to one of the speakers. Pick the connection that delivers a solid center
image between the speakers as well as best bass response.
CAUTION: After lead ends are inserted and the screws tightened down, be sure there are no free strands
that could cause shorting!
Video connections
(BASIC/ADVANCED/EXPANDED)
Composite Video
The buffered, composite video output from the MRC44 Controller/Amplifier will drive a VIDEO INPUT on a
TV or monitor directly. Use RG-6 coaxial or RG-59 quadshield cable with RCA type phono plugs on each
end. This connection can be run for 100 feet.
Modulated Video
When using the RF/ANT input on a television, use RG-6 coaxial or RG-59 quadshield cable with "F"
connectors on each end to connect to the RF output on the Modulator to the RF/ANT in on the zone TV.
SETTING-UP THE MRC44 SYSTEM
(BASIC/ADVANCED)
To better demonstrate the ease and versatility of programming the MRC44, Figure 13 will be used to illustrate
setup for a typical application.
(EXPANDED)
For setup of an expanded system, see Figure 24.
The MRC44 is programmed using the included Xantech Dragon Drop-IR™ program Drag450MRC and
