BEYOND YOUR EXPECTATIONS, WITHIN YOUR REACH.
INTRODUCTION
Thank you for purchasing the Remote Line Drive RLD-1.
This preamplifier is handcrafted with top quality, highly reliable components. We are confident that you will be well
satisfied with its sonic performance and find pleasure in its
functional beauty.
Before you enjoy these experiences, however, please take
a few minutes to read this Owner’s Manual and acquaint
yourself with the instructions for optimal operation. This
will ensure your listening pleasure today, and for many
years to come.
OPERATING INSTRUCTIONS
UNPACKING - Be sure to save the original box and packing materials. Store them in a dry environment. It is best to
use the original packaging should you need to transport or
ship the RLD-1.
INSTALLATION - Place the RLD-1 as closely as possible
to its final installation location, while leaving yourself access to the rear panel. Choose a location with at least a
few inches of ventilation space around the chassis.
TAPE 2 inputs and outputs, as indicated on the rear panel.
The TAPE 2 IN jacks receive the signal from the deck; the
TAPE 2 OUT jacks send the signal chosen by the source
selector to your deck.
AMPLIFIER CONNECTION
Be certain your power amplifier is turned OFF, then connect it to the RLD-1 output of your choice. Two pairs of
outputs are provided for special applications (eg. connecting self-powered subwoofers). These are wired in parallel
and are electrically identical.
NOTE - The RLD-1 uses high-quality RCA phono jacks for
input and output connections. Please remember that selecting high quality cables for use with this revealing component will result in superior sonic performance from your
system. Your McCormack dealer will guide you in making
this important component choice.
The RLD-1 uses a removable 3-wire grounded AC power
cord. Plug the AC power cord into the RLD-1, then plug the
other end into an appropriate wall socket.
When all connections are made, move the RLD-1 to its
permanent location. Check again to be certain that all your
plugs are fully inserted, making tight connections.
LINE LEVEL SOURCE CONNECTIONS
Connect your line level sources (CD, DCC, Mini-Disc,
VCR, tuner, cassette deck, phono preamplifier, etc.) to the
input of your choice on the rear panel.
There are 5 line level inputs labeled CD, VIDEO, TUNER,
TAPE, and PH/AUX for your convenience. If you have purchased the optional phono stage, then you will want to use
the PH/AUX connectors for your turntable. If not, then use
this input for any line level source you choose.
TAPE RECORDER/PLAYER CONNECTIONS
To use monitoring facilities built into a tape recorder, connect your tape deck (R-DAT, DCC, Mini-Disc, etc.) to the
When first powered up, and with restoration of service after a power outage, the RLD-1 starts in Standby Mode.
Press the button labeled STANDBY to begin normal operation. The RLD-1 will switch to its default settings, which
are for CD input and -50 dB level settings.
Turn on your power amplifier.
BREAK-IN PERIOD
Your RLD-1 has already been burned in at the factory.
However, like all high quality components, it will still require a break-in period of approximately 100 hours before
it will sound its best. When not in use, switch the RLD-1 to

Standby mode which will shut down the displays and mute
the outputs while keeping the audio circuits powered.
CONTROLS
All front panel and remote controls are "tact" switches
which operate by pressing and releasing.
SELECT (front panel only) Pressing this switch steps sequentially through the five main inputs (CD, VIDEO,
TUNER, TAPE, PH/AUX). An led illuminates to indicate
the selected source.
CD, VIDEO, TUNER, TAPE, PH/AUX (remote control
only) - On the remote control, the five main inputs may be
directly accessed by pressing the associated button.
THEATER (front panel and remote) Theater Mode will
only operate on the Video input. When Video is selected,
this switch will toggle the unit in and out of Theater Mode.
In Theater Mode, the RLD-1 is set to unity gain, and volume and balance controls are disabled. Other functions
(Select, Monitor, Mute, Standby) work as usual.
MONITOR (front panel and remote) Pressing the Monitor
switch toggles between the selected main source and the
TAPE 2 input.
MUTE (front panel and remote) - The MUTE circuit turns
off the main outputs, but does not affect the TAPE outputs.
VOLUME - + (front panel and remote) Press these buttons
to decrease or increase the level setting. The actual setting, expressed in dB of gain, appears for each channel in
the display window. Negative numbers indicate dB of attenuation. NOTE the volume control is disabled when the
RLD-1 is in Theater mode.
BALANCE < > (front panel and remote) - Press these buttons to shift the balance to left or right. NOTE the balance
control is disabled when the RLD-1 is in Theater mode.
STANDBY (front panel only) - This button will toggle the
RLD-1 in and out of Standby Mode. In Standby Mode all
displays are turned off except for the Standby led, which is
lit. When switching out of standby mode, the RLD-1 returns to the previously selected source and level settings.
TROUBLESHOOTING
sure it is intact. The fuse is located in a tray in the AC
power cord receptacle, located in the lower left corner on
the back of the chassis. The top section accepts a 3-prong
power cord plug. Below that is a small tray which is divided
into two sections, front and back. The back section holds
the active AC line fuse; the front section holds a spare
fuse. To open this tray, remove the power cord plug, insert
a small screwdriver in the slot at the top of the drawer and
pull out. If the fuse has blown, replace it once with the correct replacement fuse. Use only the correct replacement
fuse value and type. The correct fuse for each voltage
standard is listed in the specifications below. Check for
proper operation. If it blows again STOP!
There are no user serviceable parts in the RLD-1 other
than the AC line fuse. Contact your McCormack Dealer for
service options.
