RECOMMENDED CALIBRATION PROCEDURE
e CP 64 is a very versatile instrument. While this allows it to conform to the requirements of a large number of system appli-
cations, it also results in complexity. For this reason, it is very important to use an organized approach to system calibration. Once
the internal switches are set and the system is connected, take the time for proper calibration. e 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 reshold is set to +20 dBu
• Page Zone Levels are set to minimum
• Remote Control is not selected
• Page Zone Assign is set to Both
e following procedure assumes that microphones are used for Page sources. e procedure (except for the exact wording) is the
same for other Page sources.
Make sure the POWER is off!
Control Presets:
Page settings (repeat for second page input):
• Input Pad Mic/Line as required

• Program Priority Assign Off
Zone Settings (repeat for second zone):
• Zone Level Max
• Program Select L1 (if your input is on L1).
• Ducker OFF
• Ducker Depth Center (about 15 dB)
• RMT (Remote) Out (front panel)
