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

 

 

 stereo, 450 W+450 W into 8

 

 

 stereo.

2,000 W into 4

 

 

 bridged, 1,300 W into 8

 

 

 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.
