RECOMMENDED CALIBRATION PROCEDURE
The CP 64 is a very versatile instrument. While this allows it to conform to the requirements of a large number of system
applications, it also results in complexity. For this reason, it is very important to use an organized approach to system calibra-
tion. Once the internal switches are set and the system is connected, take the time for proper calibration. The following is an
ordered list of system adjustments that should make calibration easy and result in optimum performance. Most important:
• Program Priority Assign is set to Off
• Ducker is Off
• Zone Limit Threshold is set to +20 dBu
• Page Zone Levels are set to minimum
• Remote Control is not selected
• Page Zone Assign is set to Both
The following procedure assumes that microphones are used for Page sources. The procedure (except for the exact
wording) is the same for other Page sources.
Make sure the POWER is off!
