3.1.3 Recalling Presets (routing patterns) 
The number of presets accessible from front panel is the same as # of inputs 
(however through the IP or Serial port, the unit can store and recall up to 16 
presets even for an 8 input Model)  
Press and release the Preset button. The button will light up solid. Then press and 
release the input button (it will light up) and hit ENTER. You have 8 seconds to 
hit ENTER or the action will be cancelled. This will recall the desired preset tie 
pattern.   
Note that a recalled preset replaces the current tie configuration, which will be 
lost unless it has been stored as another preset. 
 
3.1.4 Saving Presets (routing patterns) 
The current tie configuration can be saved as a preset to be called up later on.  
To save the current AV routing pattern, press and hold the PRESET button for 3 
sec, the backlit LED will start flashing (this means that save preset function has 
been activated). Press the desired input button to save the preset (the button with 
light up). Then hit the ENTER button to complete the operation. Again, you have 
8 seconds to complete this sequence.  
 
3.1.5 Disconnecting all AV outputs (blank preset) 
There is a hidden blank preset (think of it as Preset #0) in the system that can be 
very useful in clearing all ties. A blank preset is a preset without any ties selected 
in it. To Recall a blank preset, press and release the Preset button, press and hold 
the ARROW UP (▲) button, and simultaneously press the ARROW DOWN (▼) 
button. This will clear all ties. From here, the user can make new ties or save the 
blank tie over a preset that had ties in it which effectively erases that preset. 
 
3.1.6 To reset system to factory defaults 
Disconnect the AC power from the unit. Press and hold the ENTER button on the 
front panel while plugging in AC power. Continue to hold the ENTER button 
until all LEDs on the front panel flash on. System reset clears all ties, presets, 
schedule settings, and unit name.  
 
3.1.7 Using the Front Panel VU meter 
This function is useful for ensuring no noticeable volume difference among the 
audio sources for models AC1121A and AC1123A. 
Press and hold the AUD button for approximately 3 seconds until the backlit LED 
starts to blink. Press and release an input button whose audio you want to adjust.
