Line level
In order to match levels with your preamplifier or your power amplifier, the HD
DAC features two selectable output levels. For a 0 dB FS (maximum level) you
may select either 1.3 V (LOW) or 2 V (HIGH) rms as your analog output level.
To change the level, go to:
PRESS CTRL
PRESS CTRL

HD DAC is currently
set.
To change the level, press the Controller and select LOW or HIGH, then confirm
by pressing once again the Controller.
Line mode
The HD DAC can operate as a pure D/A converted connected to an external
preamplifier or integrated amplifier. In this case, you should have a fixed output
level: DIRECT.
Should you wish to use its built-in volume control, you should select a VARIABLE
output.
If you select DIRECT, then the signal won’t pass through the potentiometer, and
no control is possible.
You may select DIRECT or VARIABLE, it won’t affect the headphone amplifier, the
latter will always go through the potentiometer allowing the playback level to be
adjusted.
Go to:
By default, VARIABLE is
selected, as show here.
Note:
When you change the setting from VARIABLE to DIRECT, the HD DAC
will be muted, a blinking X will appear on the display. This is just to
remind you that you are now in DIRECT mode, the signal will be at full
level. If you have changed this setting by accident, there is time to
come back to VARIABLE before damaging your hearing or your
speakers.
