CP2000—Owner’s Manual
1 Introduction
Welcome
Thank you for choosing the Yamaha CP2000 Power Amplifier. Based on a new
improved version of Yamaha’s
EEEngine
amplifier technology, the CP2000 is a versatile
two-channel power amplifier, offering high-power, superb sonic performance, and reli-
ability, all backed by the Yamaha tradition of excellence in professional audio.
CP2000 key features include
• 650 W+650 W into 4
Ω
stereo, 450 W+450 W into 8
Ω
stereo.
• 2,000 W into 4
Ω
bridged, 1,300 W into 8
Ω
bridged.
• Yamaha Speaker Processing matches the CP2000 to the Yamaha S115 and S112 loud-
speakers.
• Three operating modes are provided: STEREO mode in which Channel L and Channel
R operate independently, PARALLEL mode in which the channels operate indepen-
dently but are both fed from the Channel L inputs, and BRIDGE mode in which both
channels are combined to form a massive 2000 watt single-channel amplifier.
• Improved
EEEngine
technology using MOSFET output devices.
• Compared to conventional designs,
EEEngine
’s energy saving capabilities reduce power
consumption by up to 50% and cut heat generation by up to 35%.
• Built-in limiter prevents excessive output signal distortion, protecting both speakers
and eardrums.
• Electronically balanced XLR-type and 1/4" phone jack input connectors.
• 5-way binding posts and 1/4" phone jack output connectors.
• Signal and CLIP indicators on each channel provide signal presence and clip warning.
• Relay-based protection system protects both amplifier and speakers if heatsink over-
heating occurs or a DC offset is detected at the outputs.
• TEMP indicator warns of heatsink overheating.
• Variable-speed low-noise fan regulates the system temperature even under the most
demanding conditions. While the CP2000 is idle, the fan stops for silent operation.
