XDA-3 Front Panel

1. Headphone Jack (1/4")
The XDA-3 includes a monolithic high performance current feedback headphone amplifier with
wide dynamic range and exceptionally low noise and distortion. When there are headphones
plugged into this jack, the main outputs are muted, and the Volume buttons on the front panel
(and on the remote control) adjust the headphone output level.
2. Input Selector Buttons
Press either of the Input Selector buttons to cycle the XDA-3 through its available inputs. Each
Input is momentarily displayed full-screen on the front panel OLED display as it is selected.
(The Input buttons on the remote control switch directly to each input.)
3. Front Panel Display (Alphanumeric OLED Display)
The easy to read alphanumeric OLED display on the front panel of the XDA-3 normally displays
the Volume setting, the selected Input, and the sample rate of the incoming audio signal. It
switches to a more focused single-mode display when relevant information is available. For
example, when you change Volume, a full screen Volume bar is displayed and, when you select
an Input, the name of that Input is displayed full screen. The brightness of this display can be
adjusted by using the Dim button on the remote control.
4. Volume Up and Volume Down Buttons
Press the Volume Up and Volume Down buttons to raise and lower the Volume on the XDA-3.
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.
