Introduction
Congratulations on selecting the MRD-D1 multi-room distribution
system for use with your Sony brand DSS ®(Digital Satellite System).
With it you will be able to enjoy crisp, clear pictures from the DSS
receiver at up to five additional viewing locations within your home. As
an added benefit, MRD-D1 will also distribute video and audio from a
second source such as a VCR or laserdisc player. -........
Each video source connected to MRD-D1 is capable of being operated
by infrared (IR) remote control from any of five viewing locations. The
system is provided with one IR target (the device which enables IR
commands to be sent from a remote viewing location to the video
source) and two IR emitters (devices which actuate the video source).
In the event you require remote control at additional viewing locations
within your home, your Sony dealer can provide additional IR target
units (EAC-T1) for use with MRD-D1.
To order Sony brand DSS Accessories, visit your local retailer or call toll
free 1-800-488-7669 Monday-Friday 7:00am - 7:00pro and Saturday
8:00am - 4:30pm CST. American Express, Visa, Master Card, and
Discover Card accepted.
Please read this manual thoroughly before attempting installation.
Note
•The MRD-D1 distributes mono audio which is not full DSS signal quality.
4 Introduction

Inspection
Your MRD-D1 multi-room distribution system consists of a modulator
unit, a power supply, two IR emitter assemblies, an IR target, four
mounting screws, and a channel tuning tool as shown.

Preparation for Use
Before installing your MRD-D1, please read the following brief
discussion of its parts and what they do:
Modulator Unit
The modulator unit accepts the video input from your Sony DSS
receiver and one other video device of your choosing (VCR, laserdisc
player, etc.) and creates an "in-house" television channel for thefff_T14e
unit also accepts the input from an off-air antenna or cable service and
provides some amplification of the signal. The outputs from the
modulator unit can be connected to up to five TVs: two located within
30 ft. of the unit, and three located within 100 ft. of the unit. When
connected to remote TVs, a Sony IR target EAC-T1 must be used in
order to use your remote control.
Power Supply
The MRD-D1 is designed to operate from a 12 V AC power source. The
power supply provided with your system will make tl_e necessary
voltage conversions when connected to 110 V AC, 60 Hz power.
Under no circumstances should you substitute the power supply
provided with MRD-D 1.
IR Emitters
There are two IR emitters provided with MRD-D1. The IR emitters
connect to the modulator unit and are to be placed over the IR receiver
located on the video sources. One emitter is provided for each source.
IR_Target
One IR target is provided with MRD-D1. The IR target is to be installed
in a remote viewing room and is connected to the modulator unit via a
75-ohm coaxial cable. This IR target must be exposed so you can point
your remote control at it.

Make certain that your present system is functioning correctly
prior to installing MRD-D1. Ensure that all antenna or cable
signals are being received on all TVs that will be connected to
MRD-D1.
Determine whether your home TV service is cable (CATV) or off-
air (antenna).
Note
•You should make written notes on this step so that you can refer to
them later.
El If cable: determine the highest channel number delivering a
picture signal, excluding channels 95-99. If uncertain, contact,
your local cable company.
If antenna: tune the TV one channel at a time from channel 14
to channel 36. Write down the channel number of each channel
that has no trace of a_picture.
Determine which of the remote TVs will be provided with IR
control capability using the IR target provided with MRD-D1.
Note
•You can, at a later time, move the target to another remote TV, or add
more IR targets. For now, you need to plan where the target will be
used.
Select an installation location for the modulator unit that satisfies
all of the following conditions:
El is close to the DSS receiver and the second video source;
has 110 volt AC power within easy access;
El can connect easily to the coaxial input that delivers either the
antenna or cable signal to the main TV;
_-- permits _onnection of the IR emitters to the video sources
within the length of the emitter cable (6 ft.);
El is clean and dry and likely to stay that way. Mounting near
window or door openings is strongly discouraged.

Fasten the modulator unit to the desired location using the
mounting screws provided with the unit. The orientation is not
critical. Mounting that enables clear access to the top of the unit for
tuning and easy access to connectors on the left and right sides of
the unit is most desirable.
Connect the modulator unit to the video sources (when viewed
from the end, the video and audio input connectors on the left are
for INPUT 1 and those on the right are for INPUT 2) ..............
Connect the DSS receiver video and audio outputs to INPUT 1 and
the second video source (optional) to INPUT 2.

Connect the coaxial cable from the antenna or the cable source
directly to the modulator unit using the connector labeled RF IN.
Connect the main TV to the modulator unit using a coaxial cable
between the VHF/UHF input of the TV and one of the connectors
labeled LOCAL RF OUT on the modulator unit.

•When the second video source is a VCR, connect the other LOCAL RF OUT
connector to the VCR input connector using a coaxial cable.

9Connect the IR emitters to the modulator unit. With firm pressure,
place one of the adhesive backed IR emitters over the remote
sensor on the DSS receiver. Repeat the procedure for the second
video source.
