INPUTs

 

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 con-
nected, either connector can be used to distribute the input signal to another amplifier. 
See “Daisy Chaining Inputs” on page 12 for more information.

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 speak-
ers.

 

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 con-
nected 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. See “Connecting S115 and S112 loudspeakers” on page 11 
for more information.

 

D

 

SPEAKERS connectors

 

The outputs for each CP2000 channel comprise of one 1/4" phone jack and one pair of 
5-way binding posts. The 1/4" phone jacks accept 1/4" phone plugs, while the 5-way 
binding posts offer several methods of connection, including single or double banana 
plugs, spade lugs, or bare wires. See “Connecting Speakers” on page 9 for more infor-
mation. See also 
“Hookup Examples” on page 4.
