XDA-3
Volume (+) & Volume (-) Button
Press the Volume (+) and Volume (-) buttons to raise and lower the Volume. A single press moves
the Volume one step, holding the button causes the Volume to continuously move smoothly up
or down. When there are headphones plugged in, the Volume buttons on the front panel (and on
the remote control) adjust the headphone output level. When no headphones are plugged in, the
Volume buttons adjust the main output level. Both settings are stored independently.
Volume control for both digital and analog audio inputs is via a precision digitally controlled
analog resistor ladder network, which moves in precise 0.5 dB steps, and ensures absolute
repeatability and near-perfect channel matching at all Volume settings. Unlike digital volume
controls, the XDA-3's analog volume control doesn't reduce bit depth, nor introduce grain or
distortion, at low volume settings.
Note: If the XDA-3 is in Mute Mode pressing the Volume (+) button will toggle Mute Off.
