OWNER'S MANUAL
Main Features
@ Lightweight, Compact, and Energy-Efficient
Employing the latest developments in high-efficiency amplifier technology, the CPM-300 packs a powerful 150 watts
per channel {into 4 ohms), yet weighs a mere 6.0 kilograms, consumes only half the energy, and generates just
one-third the heat of previous powered mixers (in actual operation, compared with other Roland mixers). The com-
pact design means you can easily find space to set it up, and it travels a lot easier. The handles make this piece of
gear easy to carry, too. The CPM-300 is ideal as a simple PA for a variety of events, and since it is air-cooled, it
stays quiet.
@ Packed with Features, Yet Simple to Operate
The CPM-300 provides six mono and two stereo channels for a total of ten input channels. With its widely-
adjustable input circuits, the SENS knobs allow you to adjust the input sensitivity with the twist of just one control.
This allows the CPM-300 to accept a wide range of inputs, from mics to CD players to electronic instruments, all
with a simple adjustment.
@ Easy Elimination of Irritating Feedback
The CPM-300 features a digitally processed "Anti-Feedback" function. Feedback is automatically detected and elim-
inated the instant it begins.
@ The high-quality internal effects include four types of digital reverb.
A few simple steps let you perform with these superior effect sounds, from karaoke-style echo to concert hall reverb
sound, with ease.
@ Limiter Included in Power Amp Section
The mixer's amplifier is equipped with a limiter circuit, providing protection against the clipping that can cause distor-
tion and blown speakers.
@ Protection Circuits for Added Reliability
With a PC Limiter Circuit which guards against shorting in the output, a Thermal Protection Circuit, a speaker-saving
DC Detection Circuit, a Muting Circuit that cuts the "shock noise" that occurs when the power is switched on, and
more, the CPM-300 features a variety of protection circuits to ensure dependable operation.
New ECOS High-Efficiency Amplifier Technology
ECOS (Etficiency Control Operation System) is a new high-efficiency amplifier technology developed by Roland. With this technology, amplifier
power consumption is only 1/2 that of previous amps, while generating only 1/3 of the heat, all with no sacrifice in sound quality. As a result, the
heal dissipation and power sections are smailer, making the mixer fighter and more compact than previous models.
