The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. * This applies only to products distributed by YAMAHA KEMBLE MUSIC (U. K. ) LTD. Important Information i Important Information Please read the following before using the CP2000 Warnings · Do not allow water to enter this unit or allow the unit to become wet. [. . . ] The green indicators light up when the output voltage is 2 V or greater, while the yellow indicators light up when it's 20 V or greater. CP2000--Owner's Manual Rear Panel 3 Rear Panel 1 4 2 1 1 2 CHANNEL R INPUT STEREO BRIDGE PARALLEL OFF (­) BRIDGE (+) CHANNEL L (BRIDGE) NEUTRIK CHANNEL R CHANNEL L SPEAKERS 2 3 1 ON 2 3 1 YAMAHA SPEAKER PROCESSING 23 A INPUTs 5 The inputs for each CP2000 channel comprise of one 1/4" phone jack and one XLR-3-31-type connector. Both connectors are electronically balanced, although they can also be used with unbalanced sources. See "Connecting Inputs" on page 7 for more information. See also "Hookup Examples" on page 4. Since the phone jack and XLR-type connector on each channel are internally connected, either connector can be used to distribute the input signal to another amplifier. See "Daisy Chaining Inputs" on page 12 for more information. B Mode switch This switch is used to select the amplifier's mode of operation: STEREO, PARALLEL, or BRIDGE. STEREO--In this mode, which is typically used to amplify stereo sources, the L and R channels operate independently. PARALLEL--In this mode, the L and R channels operate independently but the input signal for both channels is sourced from the Channel L inputs. This mode is typically used with a mono source and allows independent volume control of two sets of speakers. BRIDGE--In this mode, the L and R channels are combined to form a massive 2000 watt single-channel amplifier. The input signal is sourced from the Channel L inputs, the volume level is set by using the Channel L LEVEL control, and the speakers are connected to the binding posts labelled BRIDGE. C YAMAHA SPEAKER PROCESSING switch This switch is used to activate the special EQ processing that optimizes the CP2000 for use with the Yamaha S115 and S112 loudspeakers. When other speakers are used, this switch should be set to OFF. This mode is typically used with a mono source and allows independent volume control of two sets of speakers. The following hookup example shows how the CP2000 can be used in PARALLEL mode.

CP2000--Owner's Manual Using the CP2000 7 3 Using the CP2000 Installation The CP2000 can be mounted in a standard rack and requires 2 rack-space units. [. . . ] Another layer of protection is offered by the thermostatic cutout (auto-reset type) built into the CP2000 power supply transformer. If abnormal operating conditions, such as a shorted load or overload, continue for a long period of time, the thermostatic cutout CP2000--Owner's Manual 12 Chapter 3--Using the CP2000 disconnects the AC power when the transformer reaches a certain temperature and the POWER indicator goes out. Once the transformer has cooled down, the thermostatic cutout automatically closes, reconnecting the power, the POWER indicator lights up, and normal operation is resumed. Daisy Chaining Inputs Since the phone jack and XLR-type connector on each input channel are internally connected, input signals can easily be distributed to other amplifiers by daisy chaining the inputs, as shown below. 2 1 1 2 CHANNEL R INPUT STEREO BRIDGE PARALLEL OFF (­) BRIDGE (+) CHANNEL L (BRIDGE) NEUTRIK CHANNEL R CHANNEL L SPEAKERS 2 3 1 ON 2 3 1 YAMAHA SPEAKER PROCESSING 2 1 1 2 CHANNEL R INPUT STEREO BRIDGE PARALLEL OFF (­) BRIDGE (+) CHANNEL L (BRIDGE) NEUTRIK CHANNEL R CHANNEL L SPEAKERS 2 3 1 ON 2 3 1 YAMAHA SPEAKER PROCESSING ST OUT Mixer CP2000--Owner's Manual Troubleshooting 13 Troubleshooting The following table explains the operation of the CLIP, TEMP, and PROTECTION indicators, typical situations in which they may light up, and what action to take if and when they do.
