MCD-1000
OPERATION & INSTALLATION
MANUAL

The MCD-1000 is a four-hour, continuous play CD player with a built-in 25-watt amplifier.
CONTINUOUS MUSIC The single disc tray-type drive mechanism plays Muzak's specially
formatted CDs, so you'll enjoy four hours of uninterrupted music. The disc will continuously repeat
until you're ready to change discs. The player is equipped with a volume control and push-buttons
for play/stop, forward and back. It also contains an accessory slot for a Bose* equalizer or other
signal processing module.
PERFECT FOR BUSINESSES This CD player is designed for commercial environments,
with a four-track format and status LEDs (light emitting diodes) indicating power, play and
shuffle modes.
BUILT-IN AMPLIFICATION The MCD-1000 features a built-in 25-watt amplifier, eliminating the
need and cost of a separate amplifier. If extra amplification is required, this player allows you to
connect a separate mono or stereo amplifier that fits your needs.
NATIONWIDE SALES & SUPPORT Best of all, it's from Muzak! That means your discs will carry
only superior quality business music, programmed to attract customers and increase sales. Plus,
you'll have the ongoing support of Muzak's nationwide sales and service network.

installation/safety instructions
1. Keep these instructions.
2. Heed all warnings.
3. Follow all instructions.
4. Do not use this apparatus near water.
5. Clean only with a damp cloth.
6. Do not block any of the ventilation openings. Install in accordance with the manufacturer's instructions.
7. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including
amplifiers) that produce heat.
8. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding type plug has two blades and a third grounding
prong. The wide blade, or the third prong, are provided for your safety. When the provided plug does
not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
9. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles,
and the point where it exits from the apparatus.
10. Only use attachments/accessories specified by the manufacturer.
11. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury
from tip-over.
12. Unplug this apparatus during lightning storms or when unused for long periods of time.

where to mount the MCD-1000
1. The MCD-1000 must be mounted horizontally on a secure, flat surface.
2. Locate where there is good air circulation, low dust, low humidity and normal room temperature.
3. Do not locate in direct sunlight or near heating or air conditioning units. Avoid kitchen areas where
grease, smoke or steam may contact the player.
3
13. Refer all servicing to qualified service personal. Servicing is required when the apparatus has been damaged
in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into
the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
14. Always use replacement fuses of the same rating. The MCD-1000 requires a GMA (5x20 mm) 1.6 amp/250
volt, fast acting fuse. You may substitute a GMA 1.5 amp/250 volt fuse if you are unable to find a 1.6 amp
fuse. If the fuse continues to blow, there is a fault in your speaker wiring or in the player. Call your local
Muzak Affiliate for service.

5. Do not apply adhesive tape of any kind to the disc.
6. Keep the disc away from direct sunlight or excessive heat.
7. If the disc becomes dirty, clean it with a soft dry cloth or towel. Never use paper towels as they can
scratch the surface.

SEPARATE AMPLIFIER CONNECTION TO THE MCD-1000
Larger speaker systems may require a higher wattage amplifier than the built-in 25-watt amplifier. A
higher powered amplifier may be connected to the player's stereo or mono out jacks.
MONO OUT
Connect a patch cord from the mono out to the aux or line input of a separate mono amplifier. Most
commercial sound systems are mono.
NOTE:
The mono out is a lower level than the stereo out. You may obtain a higher level mono output by
connecting a patch cord to the right channel stereo out (no left channel connection).
STEREO OUT
Connect a patch cord from the stereo out to the aux or line input of a separate stereo amplifier.
bose equalizer module connections
The Bose module is a monophonic equalizer specifically designed for Bose FreeSpace 8 or 25 speaker
systems. The EQ8 module is for the smaller FreeSpace 8 speakers only. The EQ102 module is for
FreeSpace 25, 32 and 102 speakers.

Bose module and from the EQ out jack of the Bose module to the amp in jack of the MCD-1000.
The Bose module has no adjustments.

operating the mcd-1000

8. Music playback will begin in about five to ten seconds after disc initialization and the Play LED will remain on. If any
LED remains flashing, see Error Indicaations on page 15.
9. Set the music volume for the desired volume level.
10. Set the rear panel bass and treble controls for the desired tone balance.
CAUTION — TURNING THE BASS UP TO A HIGH VOLUME MAY CAUSE DISTORTION OR DAMAGE TO THE AMPLIFIER.
11. The CD will repeat continuously until the stop or open/close buttons are pressed.
12. Press the forward button to advance to the next music track.
13. Press the back button once to play the present music track over. Press the back button twice to start from the

interlocking hookup
1. When interconnecting two players together, connect the interlock output of the first player to the start input of
the second player.
2. Connect the interlock output of the second player to the start input of the first player to complete the loop.
3. Connect a mono patch cord from the mono output of the first player to mono out of the second player.
4. Connect the speaker system to the audio output terminals of the second unit.
NOTES:
The auto start dip switches (#1) must be off for interlock operation. The disc repeat dip switches (#2) must be off
for interlock operation.
2. Connect a momentary contact switch or the backup stop output of the Muzak SS-200 silence sensor between
the MCD-1000 stop input and ground terminals.
NOTE: The auto start dip switch #1 must be off for remote control operation.

backup system operation
1. Set the SS-200 Silence Sensor Main to Backup timer according to your system requirements.
2. Set the SS-200 Silence Sensor Backup to Main timer according to your system requirements. The Auto-Reset
jumper must be in place.
3. The SS-200 will send a start pulse to the MCD-1000 after the pre-set silence time from the DBS receiver.
4. The SS-200 will send a stop pulse to the MCD-1000 after the pre-set main audio time from the DBS receiver.

routine maintenance
1. The MCD-1000 requires no routine maintenance other than an occasional light dusting.
2. Dirty discs may be cleaned with a soft cloth towel or rag with a motion from the center outward. Do not wipe in a
circular motion.
CAUTION — DO NOT USE PAPER TOWELS AS THEY SCRATCH THE SURFACE OF THE CD.
NOTES:
•Commercially available products such as laser lens cleaning kits or stick-on rings are not recommended. They do
little, if anything, to improve performance and may actually degrade performance.
•Never attempt to insert sharp metal objects in the disc tray.
•See the WHAT YOU SHOULD DO on page 15 for advice on removing jammed CDs.
operating the remote control circuit
1. Set the MCD-1000 auto start dip switch (#1) to the off position. This prevents the player from playing when the
power is switched on.
