CP-1 Digital Audio Environment Processor

The SURROUND programs work with film sound tracks to recreate the

 

Surround

 

 

 

 

 

theater experience. MONOLOGIC (10) expands the music and effects on

 

 

 

 

 

 

 

 

 

 

monaural films into the additional channels while leaving the dialog in the

 

 

 

 

 

front center. STEREO LOGIC (11) enhances music with surround speakers

 

 

 

 

 

and also allows the listener to adjust certain parameters for film sound that

 

 

 

 

 

are fixed in Program 12. PRO LOGIC (12) provides the same decoding used

 

 

 

 

 

 

 

 

 

 

in Dolby Stereo theater systems, using up to eight speakers for front, center,

 

 

 

 

 

 

 

 

 

 

side, rear and subwoofer channels.

 

 

 

 

 

The BANK button switches between the 12 factory-preset programs and 12

Bank

user registers where customized programs may be stored. The program

 

 

 

 

 

number doesn't change: if you are using Preset program 9, BANK switches

 

 

 

 

 

to User program 9 and vice-versa. Holding BANK for a few seconds puts

 

 

 

 

 

the CP-1 into Configuration mode, in which the three Parameter buttons

 

 

 

 

 

adjust the LCD contrast and select one of the 12 speaker setups illustrated

 

 

 

 

 

on page 13.

 

 

 

 

 

The three PARAMETER buttons allow selection and adjustment of variable

Parameter

parameters within each program. Pushing PARAM displays the current

 

 

 

 

 

parameter for five seconds; pushing it again before the display changes

 

 

 

 

 

selects the next parameter. Pressing PARAM UP or DOWN will display and

 

 

 

 

 

adjust the current parameter, whether or not PARAM has been pushed. A

 

 

 

 

 

single push changes the parameter by one unit; holding the button for more

 

 

 

 

 

than one second causes the values to change rapidly in an auto-repeatmode.

 

 

 

 

 

PARAM can also put the CP-1 into TEST mode. (See page 19.)

 

 

 

 

 

EFFECT: UP and DOWN adjust the level of all signals added by the CP-1.

Effect*

BALANCE: F and B adjust the levels of the rear speakers relative to the

Balance*

sides and fronts.

 

 

 

 

 

BALANCE: L and R adjust the left/right balance of all speakers: front, sides

 

 

 

 

 

and rear. It assumes the function of the balance control on your preamp or

 

 

 

 

 

receiver.

 

 

 

 

 

VOLUME: UP and DOWN adjust the level of all channels simultaneously.

Volume*

It assumes the function of the volume control on your preamp or receiver.

 

 

 

 

 

SYSTEM MUTE turns off all outputs and lights both SYSTEM and EFFECT

Mute

MUTE LEDs. Pushing EFFECT MUTE while in system- mute mode turns

 

 

 

 

 

the effects alone back on.

 

 

 

 

 

EFFECT MUTE alternately turns off and on all signals added by the CP-1.

 

 

 

 

 

Use it to compare the sound with and without CP-1 processing. In TEST

 

 

 

 

 

mode EFFECT MUTE clears all user memories. (See page 19.)

 

 

 

 

 

*The first push of either of this pair of buttons displays the current value for five seconds; another push during that time increases or decreases the displayed value. Holding the button down for 1 second engages auto-repeat.
