Encoder Switch:
The Encode Knob has a pushbutton switch function that is activated by gently
pushing the Encoder Knob inwards towards the panel.
Power On:
When off, a momentary push/release will turn the unit on.
Power Off:
A push/hold for between 2-5 seconds followed by release will shut the
unit off.
Mute:
When Un-Muted a momentary push/release will Mute the unit.
Un-Mute:
When Muted, a momentary push/release will Un-Mute the unit.
LDR6 Only - Input Select:
A push/hold while also turning (left or right) will put the
unit in Input Select Mode and allow selection of the desired input by turning the
encoder. The selected input (the selected LED will be lit) will take effect upon
release as indicated by a brief flashing of the Status LED.
Balance Adjust:
A push/hold of between 5-10 seconds followed by release will
place the unit into Balance Adjust Mode and allow adjusting the left-right channel
balance by rotating the encoder in the desired direction. Once you’ve adjusted the
balance, a brief push/release will lock in the new balance setting and return the unit
to normal Volume Control Mode.
Balance Reset:
A push/hold for greater than 10 seconds followed by release will
reset the Balance to zero upon release.
Encoder:
The Encoder Knob is a rotary switch. Unlike a conventional potentiometer, the
encoder has no hard stops (rotational limits). It will turn an infinite number of times
in either direction. The encoder sends switch pulses to the DCU. Going
from zero to
full volume will take [approximately 2 full rotations of the Encoder Knob. It’s
possible to spin the Encoder Knob faster than the DCU is capable of detecting.
Continuing to turn the encoder in the same direction once the LDR6 has reached
minimum or maximum volume serves no useful purpose.
The Encoder’s rotary functions are only active when the unit is turned on.
Volume:
In Volume Control Mode (the default mode), turning the encoder
clockwise will raise the volume, turning the encoder counter-clockwise will lower
the volume.
Un-Mute:
When the unit is Muted (Status LED blinking slowly), turning the Encoder
