Ш Before You Begin
Thank you for purchasing the Roland CM-300 Sound Module. The CM-300 contains a
variety of quality GS sounds which can be used to enhance any MIDI music system. In
order to realize the full potential of the CM-300, and to ensure years of trouble-free service,
please read this manual in its entirety.
B Main Features
@ The CM.300 contains a GS sound source, Roland's newly implemented sound-
arrangement format.
The GS Format was created so that sound modules would respond in a somewhat
uniform manner to incoming MIDI message. Song data written specifically for a
GS-compatible sound module should play back in roughly the same way on any other
GS-compatible sound module.
€ The CM-300 is capable of producing up to 24 voices at any one time. With the
availability of such a variety of sounds, it is very easy to achieve any number of unique
ensemble textures.
@ The CM-300 also comes equipped with reverb and chorus effects that can further
enhance any sound.

B Important Notes
Be sure to use only the adaptor supplied with the unit. Use of any other power adaptor
could result in damage, malfunction, or electric shock.
[Power Supply |
[Placement |
| Maintenance |
When making any connections with other devices, always turn off the power to all
equipment first; this will help prevent damage or malfunction.
Do not use this unit on the same power circuit with any device that will generate line
noise, such as a motor or variable lighting system.
The power supply required for this unit is shown on its nameplate. Ensure that the line
voltage of your installation meets this requirement.
Avoid damaging the power cord; do not step on it, place heavy objects on it ete.
When disconnecting the AC adaptor from the outlet, grasp the plug itself; never pull on
the cord.
H the unit is to remain unused for a long period of time, unplug the power cord.
Do not subject the unit to temperature extremes (eg. direct sunlight in an enclosed
vehicle). Avoid using or storing the unit in dusty or humid areas or areas that are
subject to high vibration levels.
Using the unit near power amplifiers (or other equipment containing large trans-
formers) may induce hum.
This unit may interfere with radio and television reception. Do not use this unit in the
vicinity of such receivers.
Do not expose this unit to temperature extremes (eg. direct sunlight in an enclosed
vehicle can deform or discolor the unit) or install it near devices that radiate heat.
For everyday cleaning wipe the unit with a soft, dry cloth (or one that has been slightly
dampened with water) To remove stubborn dirt, use a mild neutral detergent.
Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth.
Never use benzene, thinners, alcohol or solvents of any kind, to avoid the risk of
discoloration and/or deformation.

[Additional Precautions |
Q Protect the unit from strong impact.
@ Do not allow objects or liquids of any kind to penetrate the unit. In the event of such
an occurrence, discontinue use immediately. Contact qualified service personnel as
soon as possible.
© ^ small amount of heat will radiate from the unit, and thus should be considered normal.
@ Before using the unit in a foreign country, consult with qualified service personnel.
@ Should a malfunction occur (or if you suspect there is a problem) discontinue use
immediately. Contact qualified service personnel as soon as possible.
Q To prevent the risk of electric shock, do not open the unit or its AC adaptor.

(Control Change) messages.
€ AUDIO (Audio Signal Indicator Light)
Regardless of where the volume knob is set, this lights to indicate that a signal (above
the threshold level) is being output.

(amplifire)
(1) Plug the cables into the CM-300's Audio Outs.
Connect the quarter-inch plugs to the CM-300's Audio Out jacks.

@ Plug the other ends of the cables into the external input jacks (AUX IN or LINE IN)
of the audio device you're using. If the audio device inputs use RCA connectors,
remove the quarter-inch adaptors from the ends of the cables.
Be sure to match the L and R outputs of the CM-300 with the L and R inputs of the
audio device.
Under no circumstances should you connect the cables to the MIC IN or PHONES
jack of your audio equipment damage could result to the equipment or speaker
systems.
@ Using Headphones
Use headphones that have an impedance between 8 and 150 ohms. Connecting head-
phones will have no effect on the signal output from the CM-300's Audio Outs.
