Volume Control
Smooth and sensitive, the Volume control is in fact a high quality rotary encoder which controls a Burr Brown precision
attenuator under microprocessor control. The ring of blue LEDs around the volume control act as a visual indication of
the volume setting. This has the advantage of being clearly visible from a distance or when using the remote control.
The blue LEDs turn on in a 1,1&2, 2, 2&3, 3 etc. sequence in order to double the number of visible steps. There is twice
this number of actual steps and the gain control employs a logarithmic taper which matches the way we perceive
loudness. This method of volume control permanently ensures the highest fidelity without the gradual degeneration
experienced with conventional motorised volume controls. The volume control has no effect on the tape, S/PDIF and
USB outputs.
Mute
Pressing the MUTE button during playback causes the volume to fade rapidly to zero. A second press restores the
previous volume level.
Setup
The key to Pyxis simplicity is that settings are made and stored on an input associative basis. In other words all the
settings made, BASS, TREBLE, BALANCE and GAIN are stored separately for each input and recalled when the input is
selected. Press the SETUP button to enter set-up mode. Bass is the default parameter. Subsequent presses on the SETUP
button cycle through BASS TREBLE BALANCE and GAIN. A further press loops back to BASS. Adjust the current parameter
with the Volume knob. Indicator LEDs at the bottom of the Volume control circle show the parameter the knob will
affect currently and the blue annular LEDs show the current value.
To exit set-up mode and save all parameters for the currently selected input source simply press and hold the SETUP
button for three seconds until the parameter LED goes out.
All settings are remembered in stand-by mode. When the unit is powered off all settings are remembered but the input
defaults to phono when the unit is re-powered subsequently.
Note : The GAIN setting affects both main and record outputs, other settings do not affect the record outputs.
