Introduction
Congratulations on selecting the MRD-Dl 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-Dl will also distribute video and audio from a
second source such as a VCR or laserdisc player.
Each video source connected to MRD-Dl 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-Tl) for use with MRD-Dl.
To order Sony brand DSS Accessories, visit your local retailer or call toll
free 1-800-488-7669 Monday-Friday 7;00am - 7:00pm 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-Dl distributes mono audio which is not full DSS signal quality.
4 Introduction
Inspection
Your MRD-Dl multi-room distribution system consists of a modulator

Introduction
Preparation for Use
Before installing your MRD-Dl, 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 them. The
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-Tl must be used in
order to use your remote control.
Power Supply
The MRD-Dl is designed to operate from a 12 V AC power source. The
power supply provided with your system will make the necessary
voltage conversions when connected to 110 V AC, 60 Hz power.
Under no circumstances should you substitute the power supply
provided with MRD-Dl.
IR Emitters
There are two IR emitters provided with MRD-Dl. 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-Dl. The IR target is to be installed
in a remote viewing room and is connected to the modulator urrit via a
75-ohm coaxial cable. This IR target must be exposed so you can point
your remote control at it.
Introduction
Installation Instructions
1 Make certain that your present system is functioning correctly
prior to installing MRD-Dl. Ensure that all antenna or cable
signals are being received on all TVs that will be connected to
MRD-Dl.
2 Determine whether your home TV service is cable (CATV) or off-
air (anterma).
Note
• You should make written notes on this step so that you can refer to
them later.
□ If cable: determine the highest charmel number delivering a
-^cture signal, excluding channels 95-99. If uncertain, contact
your local cable company.
□ If antenna: time 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.
3 Deternune which of the remote TVs will be provided with IR
control capability using the IR target provided with MRD-Dl.
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.
4 Select an installation location for the modulator unit that satisfies
all of the following conditions:
□
is close to the DSS receiver and the second video source;
□
has 110 volt AC power within easy access;
□
can connect easily to the coaxial input that delivers either the
antenna or cable signal to the main TV;
permits connection of the IR emitters to the video sources
within the length of the emitter cable (6 ft.);
□
is clean and dry and likely to stay that way. Mounting near
window or door openings is strongly discouraged.
Installation Instructions
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 cormectors 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.

8 Connect the main TV to the modulator unit using a coaxial cable
between the VHF/UHF input of the TV and one of the cormectors
labeled LOCAL RF OUT on the modulator unit.
Note
• Whe7t the second video source is a VCR, connect the other LOCAL RF OUT
connector to the VCR input connector using a coaxial cable.

9 Connect 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.

Note
• You may have to refer to the owners manual of the second video
source to determine the location of its remote sensor.
Your modulator unit is now ready for use and can be turned on,
tuned and tested without connecting the remote TVs. If you wish
to turn on now, proceed to the section of this manual dealing with
set-up and tuning the modulator unit on page 11. If you wish to
connect the remote TVs now, proceed to page 10.
Installation Instructions
Connecting the Remote TVs
1 MRD-Dl will support (provide signal for, and IR remote control of
two video sources for) five remote TV locations. Connect the
modulator unit directly to each TV via a 75-ohm coaxial cable and
an IR target.
Notes
• Additional IR targets can be added as desired. They are available from
your Sony dealer.
• If the system is improperly tuned, the power indicator will blink. Do
not ignore a blinking power indicator even if the TV is showing a
picture. Repeat the tuning procedure.
10 Installation Instructions
Setting up and Tuning the Modulator
Perform the following steps after your multi-room distribution system
has been connected properly.
1 Connect the output (mini-jack) of the power supply to the modulator
unit and plug the power supply into a 110 V AC wall outlet.
The green LED Power indicator should illuminate. If it does not,
recheck all power connections.
2 Turn on the main TV. The mode of your TV (CATV or antenna)
will determine the "in-house" channels you will use.
□ If antenna, you will use UHF channels between 14 and 35
inclusively.
□ TF cable, you will use CATV channels between 54 and 86
inclusively.
Refer to your notes made of channels delivered to your home
(page 7).
3 Select your "in-house" channels and make a written note of what
they will be. Select a charmel for the second video source even if
one will not be used.
□ For CATV: use channels higher than that of your notes.

• If the MRD-Dl is improperly tuned, the power indicator will blink. Do
not ignore a blinking power indicator even if the TV is showing a
picture. Repeat the tuning procedure until the power indicator is
steady on.
4 Tune your TV to the channel you selected for INPUT 1. Turn on
the DSS receiver.
5 Using the tuning tool provided, turn the first two rotary controls
on the top of the modulator unit to the channel number selected in
step 3. Begin the tuning process by setting the first digit of the
channel with the first rotary control, and then the second digit of
the charmel with the second rotary control. Tune only one channel
at a time.

Common Questions
Can the modulator be connected to a remote TV without using an IR target?
Yes, but you won't have remote control capability. You can add an IR
target at any time to get remote control capability. If you add an IR
target, unplug the modulator unit before attaching it.
Can an amplifier be used on the output of the modulator to drive a signal over longer cable paths?
No. The IR remote control feature will be defeated if an external
amplifier is used.
Can I use any remote control with the IR target?
The remote control you use with the IR target must be capable of
operating the component you want to control. The Sony RM-Y130
remote commander can control a DSS receiver, TV, VCR, cable box, and
laserdisc player, and has a learning feature for non-preprogrammed
components.
Can a splitter be used on one or more of the remote video outputs
to operate multiple TV's on that line?
No. The MRD-Dl Multi-room Distribution System is a pre-engineered
system providing optimum signal levels to each TV for clear, crisp
picture quality. Each time a splitter is added there is lowering of signal
level called insertion loss. Insertion losses upset system performance.
Additionally, not all splitters pass DC voltage. Inability to pass DC
voltage will cause the IR feature to be defeated.
Can I change from the off-air antenna to cable without problems?
Yes. Even though cable channels are set at different frequencies than
off-air channels, MRD-Dl will accommodate and work with either. If
you change from one signal source to the other, you will have to retime
your system following the procedures of this manual.
