2.2.8 Assigning Front-Panel Buttons to Formats

Any available format can be assigned to the front-panel 01, 04, 11, U1, U2, or NS

buttons. When the button is pressed, that format will be selected.

1. Pressing steps through the button selections, 01, 04,

11, U1, U2, and NS.

2. Rotate the fader knob to select one of the many format

choices available. This example shows Format 80

assigned to Button 01.

3. Press OK to save the assignment to this button.

4. Press to step to the other button choices, then rotate the

fader knob again to select the desired format.

5. Press OK to save the assignment to this button, and so on.

6. Press the illuminated format button to return to normal CP650 operation.

2.2.9 The Mute Function

Use the mute function between intermission music and starting the projector to

prevent the audience from hearing annoying thumps and leader crackle at the

beginning of the show. This function is also useful if the film breaks or runs out while

the projector is active, since it suppresses the very loud signal that occurs when

leaders or tails pass through the projector.

When you press mute, the volume automatically fades all the way down on all

channels. The button will flash, indicating that the CP650 outputs are muted. When

you press the button again, or select a new format, the volume automatically rises to

the level set by the fader.

The fade-out and fade-in time can be set to work from 0.2 to 5 seconds by following

this procedure:

1. Press , or press and hold the button while rotating the

front-panel knob to move to the Mute Fade-in Time menu.

2. Set the desired fade-in time using the front-panel knob.

3. Press OK to save your setting.

4. Press to set the Mute Fade-out Time using the same procedure.

5. Press the illuminated format button to return to normal operation.
