MAKING FINE ADJUSTMENTS

Using an RC68+ Hand-Held programmer, Fine Adjustments can be made to the individual Source Inputs and to specific Zones for Maximum Volume settings and for Maximum ON Volumes (maximum volume setting for when a zone is first powered ON).

TRIMMING SOURCE AUDIO INPUT LEVELS

NOTE: An RC68+ set to code group A8 with overlay “A” is required to set trim levels and make zone adjustments.

This procedure allows all sources to sound equally loud when switching from one to another.

1.Using an RC68+ with overlay “A”, select the input that has the lowest apparent volume level (from any zone).

2.Point the RC68+ at the IR sensor on the MRC88 Keypad (IR sensor enabled) and press the TRIM

button (button F8). This activates the TRIM mode.

NOTE: Trim mode allows 10 seconds after each button press for the next command to be executed. If 10 seconds is exceeded, simply press TRIM again. To confirm TRIM mode, press the MUTE ON button. If the sound mutes, the MRC88 Controller is NOT in the TRIM mode.

3.Select any other input that sounds louder.

4.Adjust VOLUME buttons until the apparent loudness is the same as step 1.

5.Select another input that sounds louder.

6.Adjust VOLUME buttons again until the apparent loudness is the same as step 1.

7.Repeat this procedure for each remaining input.

8.Verify settings by selecting each input again, making adjustments as necessary.

9.When the last input is adjusted, press one more input (the same or any other), to save the last setting.

10.Press the ADJ-OFF (Adjustments Off - 90) button to drop out of the TRIM mode. (TRIM mode will automatically drop out if you wait more than 10 seconds). The TRIM settings are now saved for all zones, completing this procedure.
