UNPACKING

Before your new GCD-700 left our factory, it was carefully inspected for physical imperfections and tested for all electrical
parameters as a routine part of ADCOM's systematic quality control. This, along with full operational and mechanical testing,
should ensure a product flawless in both appearance and performance. After you have unpacked the GCD-700, inspect it for
physical damage. Save the shipping carton and all packing material as they are intended to reduce the possibility of
transportation damage, should your CD player ever need to be shipped again. In the unlikely event damage has occurred, notify
your dealer immediately and request the name of the carrier so a written claim to cover shipping damages can be initiated.

THE RIGHT TO A CLAIM AGAINST A PUBLIC CARRIER CAN BE FORFEITED IF THE CARRIER IS NOT NOTIFIED
PROMPTLY IN WRITING AND IF THE SHIPPING CARTON AND PACKING MATERIALS ARE NOT AVAILABLE FOR
INSPECTION BY THE CARRIER. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS BEEN SETTLED.

INSTALLING THE GCD-700

Although the GCD-700 does not generate much heat, you will ensure its long-term, trouble-free operation if you keep it away

from external sources of heat such as radiators or heat registers and provide reasonable ventilation. The GCD-700 should

never be placed with other heat producing components in a cabinet or enclosure that lacks proper ventilation.

When placing the GCD-700 with other stereo components, do not stack more than thirty pounds of additional equipment on top
of the CD player as damage may occur.

For use in professional installations, the GCD-700 may be mounted in a standard 19-inch rack using the optional RM-4 rack
mount adapters available through you local ADCOM dealer.

NOTE

WHEN PLACING THE GCD-700 ON A SHELF OR IN A RACK ENSURE THERE IS ENOUGH ROOM FOR THE DRAWER
TO FULLY OPEN. YOU WILL NEED AT LEAST NINE INCHES OF SPACE IN FRONT OF THE CD PLAYER TO
GUARANTEE PROPER CLEARANCE.

REAR PANEL CONNECTIONS

The performance of the GCD-700 depends greatly on the interconnection cables used for the player itself and its associated
equipment. All the output signal connections should be made using only high quality, low-loss audio cables such as the one
supplied with the GCD-700. The Fixed, Variable, and Digital outputs are clearly labeled on the rear panel, as well as their
respective LEFT and RIGHT channels where applicable.

WHENEVER CONNECTIONS TO OR FROM THE GCD-700 ARE BEING MADE, BE SURE THAT THE GCD-700 AND ALL
ASSOCIATED COMPONENTS ARE TURNED OFF.

FIXED OUTPUT ®

The decoded, analog audio signal is available at this output at a level compatible with most preamplifiers, tuner/preamps, and

receivers. Simply connect one end of the supplied audio cable to the FIXED OUTPUT terminal of the GCD-700, left (L) and
right (R), and the other end to the CD, AUX, or TAPE IN/PLAY input terminals, left (L) and right (R) of the preamplifier or
receiver.

VARIABLE OUTPUT ®

The decoded, analog audio signal is also available at this output, however, the level can be adjusted using the VOLUME control

buttons on the RC-700CD remote control, The VARIABLE output will be most useful when using the CD player to drive an

amplifier directly. It can also be used to drive a second system simultaneously in conjunction with the FIXED output.

Furthermore, it is useful when you want the CD playback level to match those of other sources such as a tuner or cassette deck

which may be considerably different. This can be accomplished by monitoring the different sources and making the necessary

volume adjustments using the RC-700CD remote control.

To use the VARIABLE output, connect one end of a high quality RCA audio cable to the VARIABLE output terminal of the CD

player left (L) and right (R), and the other end to the CD, AUX, TAPE IN/PLAY or main input terminals, left (L) and right (R) of
the preamplifier, tuner/preamp, or amplifier.

NOTE

THE VOLUME CONTROL ON THE RC-700CD REMOTE CONTROL WILL HAVE NO EFFECT ON THE FIXED OR
DIGITAL OUTPUTS OF THE GCD-700.

DIGITAL OUTPUT ©

The digital output from the CD being played is available at this output. This signal is designed to be used with an external

digital-to-analog converter, digital tape recorder, or other component with the necessary digitai conversion circuits built in that
accept the Sony/Phillips Digital Interface Format (S/PDIF) standard.

REMOTE ®

The DIN jack connection is for use with other ADCOM components such as the GFB-800II Music Control Center. It allows the
GCD-700 to be controlled using the remote control transmitter of the main ADCOM controi center or preamplifier by use of a
special cable. Rease consult you local ADCOM dealer for more information.

AC POWER CORD ®

This polarized AC line cord can be connected to the preamplifier’s or receiver’s auxiliary AC oufiet (switched or unswitched) or
directly into a standard wall outlet provided they suppiy a voitage consistent with the voltage requirements printed on the rear
panel of the GCD-700.

NOTE

The GCD-700’s power cord is supplied with a “poiarized” AC piug as required by UL/CSA standards and the Nationai
Electrical Code, To minimize the risk of electrical shock and to ensure minimal hum from the system, do not defeat
the polarity ensuring feature of the plug (one wide blade and one narrow blade). To prevent electrical shock, do not
use this polarized plug with an extension cord or other outlet unless the blades can be fully inserted to prevent blade
exposure.

NOTE

IF PLUGGED INTO A SWITCHED OUTLET WITH ONE OR MORE DISCS LOADED, THE GCD-700 WILL
AUTOMATICALLY START PLAYING A DISC WHEN POWER TO THE SWITCHED OUTLET IS TURNED ON.
