The Muzak CP-2500 is a four-hour, continuous play cassette deck with a built-in
25-watt amplifier.
This high-efficiency, single cassette transport unit plays Muzak's specially formatted
tapes, so you’ll enjoy four hours of uninterrupted, non-repeating music. And its auto-
reverse feature gives you continuous play until you’re ready to change tapes. The unit
is also equipped with volume and tone controls and simple push-button controls for
play, rewind, and stop.
This cassette deck is designed for commercial environments, with a four-track format
and an LED (Light Emitting Diode) display that lets you monitor which track is playing.
Its built-in Dynamic Noise Reduction* (DNR) assures a crisp, clean, full range of sound.
And its compact, contemporary design means it fits anywhere.
One of the best features of the CP-2500 is its built-in 25-watt amplifier, eliminating the
need and cost of a separate amplifier. If extra amplification is desired, this unit allows
you to bypass the internal 25-watt amplifier and connect to an amplifier that fits
your needs.
Best of all, it’s from Muzak! That means your tapes will carry only superior quality
music selections artistically designed to create an experience for your customers and
employees. Plus, you'll have the ongoing support of Muzak nationwide sales and
service network.
Muzak — creating experiences with audio architecture.

CAUTION
1. Plug deck into grounded 120 V AC outlet. If a grounded outlet is not available, use an AC outlet
adapter available from local hardware or electrical stores. Follow the instructions supplied with
the adapter.
2. Do NOT remove the round ground pin from the AC plug.
3. Always use replacement fuses of the proper rating. The CP-2500 requires a 5x20 mm GMA 1.6 amp/250
volt 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 may be a fault in your speaker wiring or in the deck. Call your local Muzak
Affiliate for service.
4. Unplug the deck in the event of lightning. High voltage surges may cause damage to the circuitry.
5. Do not block the top cover air vents; overheating may result.
LOCATION
1. Locate the deck where there is good air circulation, low dust, low humidity and normal room temperature.
NOTE: Do not locate in direct sunlight or near heating units. Avoid kitchen areas where grease, smoke or
steam may contact the deck.

the label and program number facing out.
2. EJECT BUTTON
Press the eject button to open the cassette door.
3. LED INDICATOR
The LED (Light Emitting Diode) indicator displays the operational status of the deck.
All LEDs off indicates the power is off.
A single flashing LED indicates the standby mode.
An LED on continuously indicates the play mode and the music track.
All four LEDs moving in sequence indicates the rewind direction.
4. VOLUME CONTROL
Turning this control sets the volume of the line output and the audio output (amplifier output).
5. POWER
Pressing this turns the power on and off.
NOTE: Power will come on when the power cord is first plugged in.
6. SELECT
Pressing this will change the music track.

1. LINE OUT
These terminals are for connecting the CP-2500 to a separate amplifier. Leave these terminals
disconnected if you are connecting your speakers to the built-in amplifier (Audio Output). See page 7.
Connect the +terminal to the “hot” or center conductor of the supplied patch cord.
Connect the -terminal to the “ground” or shield conductor of the supplied patch cord.
2. REMOTE CONTROL
The remote control terminals are for starting and stopping the deck from a remote location:
Shorting the start terminal to the ground terminal through a remote switch will place the deck in the
play mode.
Shorting the stop terminal to the ground terminal through a remote switch will place the deck in the
stop mode.
3. BASS & TREBLE CONTROLS
Turning these controls will increase or decrease the amount of bass and treble.
4. AUDIO OUTPUT
Connect these terminals to your speaker wires. See the connection diagrams on page 8 for more
details.
The 4 Ω(ohm) terminals are for speakers without transformers which are labeled 4 or 8 Ω.
The 70 V (volt) terminals are for speakers with transformers which are labeled 70 V.
5. AC INLET
Connect the detachable AC power cord to this receptacle.

6. FUSE HOLDER
This holds the AC line fuse. The AC power cord must be removed to gain access to the fuse. See page 14
for details on fuse replacement.

A majority of commercial speaker installations are 70-volt
systems. Relatively few are 4 Ωor 8 Ω. This is determined
at the time of installation. 70-volt systems can be identified
by the presence of a transformer mounted on each speaker
or the 70 V label. If in doubt, consult the local Muzak
Affiliate who installed the system.
NOTE: When connecting an 8 Ωspeaker load to the CP-2500
4 Ωterminals, the output power is 15 watts. A 16 Ωspeaker
load is not recommended due to the reduced output power.
The CP-2500 volume control adjusts both the amplifier audio
output and the line out.
Proper positive (+) and negative (-) polarity must be maintained
throughout your speaker wiring. There are two types of speaker
wire commonly used. The first type is color coded red (+) and
black (-). The second type, sometimes referred to as zip cord,is
polarized with a ribbed or striped conductor (+) and a plain
conductor (-).
See the wiring diagrams to the right for additional details.
CONNECTION TO A 70 V SPEAKER SYSTEM:
Connect the CP-2500 70 V + (red) push terminal to the positive speaker wire.
Connect the CP-2500 70 V - (black) push terminal to the negative speaker wire. See diagram on next page.
