…CP 64 Calibration (continued)
1. Connect the Power Supply and verify the PWR indicator lights.
2. Verify Zone Level controls are set to Maximum and that you have an active source for each of the Program Inputs you
intend to use. Select each Program Input and adjust its Input Level control to be the very loudest you would ever desire.
3. Adjust the rear panel Zone Limit thresholds so that they just start to audibly reduce the output level. This ensures that the
level in a Zone will never be louder than the maximum level you just set. If you wish one of the Zones to have a lower
maximum loudness, lower the Zone Limit threshold accordingly.
4. Turn the Zone Level controls down to a comfortable listening level.
5. Note that with the Paging Zone Level set to minimum, you will not hear the following Page. Speak very loudly (bark) into
the Paging Mic. Set the proper preamplifier gain by adjusting the Page Trim control (rear panel) so that the Page
OverLoad Indicator (rear panel) just lights. It is important to set the gain of the pre-amp before setting the Page Detect
Threshold. Repeat for second Mic if used.
6. Speak into the Page Mic in a normal voice and adjust the Page Detect Threshold (rear panel) so the Active indicator (front
panel) lights only when you speak. If the Page Detect Threshold is set too low, the Pager may gate on due to background
sound. Repeat for second Mic if used.
7. With an active Program source playing in both Zones, speak into the Page Mic. Adjust the Zone 1 and Zone 2 Page Level
controls (front panel) to provide the correct Page-to-Program mix in each zone. If the Page Detect Threshold is set too
high, there may be a delay when you start to speak. To correct, lower the Page Detect Threshold setting. If a second Page
source is used, verify that it has the same level as the first Page source (it should be close). If not, use the Page Trim
control of the second Page source to adjust its gain to match. If you change the gain of the second Page source substantially,
be sure to reset the Page Detect Threshold.
8. Set the Ducker switch to ON. With an active Program source playing, speak into the Page Mic and adjust the Ducker
Depth as required. Repeat for both Zones.
9. Set the Program Priority Assign switch as required (on rear panel). If you do not require automatic priority program
override in a zone, do not assign it. Instead, use the front panel Program Select switch to select the “P” program Input as
you would any other non-priority input.
10. If remote control is used, select the appropriate RMT switch settings on the front panel and verify that the remotes function
correctly.
11. Adjust the Equalizers as required.
…You’re all set. Enjoy.
