AUDIO ADJUSTMENTS (Z-Adjust – Installer Settings)
These settings are ‘permanent’ settings that will affect system or zone
performance whenever the system is turned on, (even after a power outage) until
the settings are changed using the following procedure:
Trim
This procedure adjusts the MRC88 Source Input levels to compensate for the
different output levels of the common sources. When this procedure has been
properly executed, the audio level of the common sources should be the same
when switching from one source to another.
With all sources ON and playing relatively similar program material:
1. Cycle through the inputs to get a reference to the relative audio levels of the
different sources.
2. Using an RC68X with overlay “A”, select the input that has the lowest
apparent volume level (from any zone).
3. Point the RC68X 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.
4. Select any other input that sounds louder.
