ZPR68-10 BASIC SETUP AND OPERATING PROCEDURES
The following procedures assume the prior connection of all eight SOURCE INPUTS and two PA640's in
a fully wired six-zone system similar to that shown in Fig.6.
• Each zone IR IN has a Xantech Key Pad and/or Xantech IR Receiver connected.
• For AC power management, six of the common sources are current sensed and two are video sensed
by the Gatekeep-IR
TM
for ON/OFF status. All are switched ON and OFF by sequenced commands from
the SmartPads and programmable remotes.
• The Common CO (Control Out) port on the ZPR68-110 controls System Power OFF status for the
GATEKEEP-IR and also turns the PA640's ON and OFF via their Remote ON/OFF inputs.
• All source components in this typical system must have their ON/OFF function controlled by IR.
• See the GATEKEEP-IR Installation Instructions for all GATEKEEP-IR programming procedures.
SETUP PROCEDURES
Turning The System ON
1. Press an INPUT button (1 through 8) on the RC68+ hand held Remote Programmer while aiming at
an IR receiver in any zone.
Note: All setup instructions in this procedure assume the use of the RC68+ or RC68 hand held Remote
Programmer.
2. Press each INPUT button and activate each source.
(Make sure each is playing).
3. Adjust VOLUME buttons to a comfortable listening level.
Adjusting Input Level TRIM
This procedure allows all sources to sound equally loud when switching from one to another.
1. Select the input that has the lowest apparent volume level
(from any zone).
2. Press TRIM button.
(This activates the TRIM mode).
Note: TRIM mode allows 10 seconds after each button press for the next command to be executed.
If you exceed 10 seconds, simply press TRIM again. You can verify whether you are still in the TRIM
mode by pressing the MUTE ON button. If the sound mutes, you are 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 your 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) button to drop out of the TRIM mode.
(TRIM mode will drop
out automatically if you wait more than 10 seconds).
The TRIM settings are now saved for all zones, completing the procedure.
Zone Adjustments
These adjustments allow customized bass, treble, balance and maximum level settings to best compliment
the acoustics and preferences for each zone.
1. Go to desired zone.
2. Select desired INPUT (source).
3. Press Z-ADJ button.
(This activates the Zone Adjustments mode).
Note: Z-ADJ mode allows 10 seconds after each button press for the next command to be executed.
