Calibration

When CP-3 Input and Output levels are set properly, the entire system will be calibrated to play films at the level intended by the director. Setting the output levels is easy, particularly if a Sound Pressure Level (SPL) meter is used. Using the PARAM and the PARAM ▲ and▼ buttons, adjust the level of each individual output until they are all the same relative level. You can use an external source for this, or the CP-3's internally generated calibration signal.

Temporarily turn the system volume down to about -20dB. Press SETUP and use the PARAM button to select OUTPUT LEVEL. Then press PARAM

▲or ▼. The display will read:

INTERNAL SOURCE

EXTERNAL SOURCE

Use the PARAM button to select the built-in signal generator (INTERNAL SOURCE) or an EXTERNAL SOURCE. With your choice selected by the cursor, press PARAM ▲ and▼ to activate your selection. PARAM is used to select the output to be adjusted; PARAM ▲ and ▼ raise and lower the level of that output in precise 1dB increments. The Level sub-menu choices are shown below.

Note that selecting INTERNAL SOURCE automatically disconnects all audio and video inputs, and plays only one channel at a time. EXTERNAL SOURCE allows all channels to be heard simultaneously.

If you are using an SPL meter, use the C-weighting with the meter response on SLOW. From your listening position, hold the meter at about ear level at arm's length (to avoid body interference). A tripod is useful here. Aim the microphone at the ceiling and set to a scale incorporating 75dB. Increase the system volume to 00dB. Now use PARAM ▲ and ▼ to raise or lower the output level of the speaker until the meter reads 75dB. Press PARAM to select the next channel specified in the Configuration menu and continue in this manner through all the channels.

Be sure to record the values on the Installation Worksheet provided at the end of this manual. Press SETUP to save the settings and return to the Setup menu.

Setting

Output Levels

NOTE: When you select the Output menu, the CP-3 auto- matically engages the Home THX Cinema mode. When you exit the Output menu, the sys- tem will return to the previously selected mode.

PAL and SECAM

NOTE: Because the CP-3 is not capable of generating PAL or SECAM composite video signals by itself, during INTER- NAL NOISE generation (when all inputs are turned off) users with PAL or SECAM TVs will have to rely on the LCD when adjusting Output Levels.
