Upon Power Up:
When switched on, the DAC1.5 will display its
software revision. The AES input will be selected
and Soft Mute will be active. The volume will be set
to 50.0 even if the fixed/variable button is in Fixed
mode.
Front Panel Control Knob:
The control knob is a continuously rotating control
with a push-switch function.
Variable Output Mode:
The DAC1.5 Variable Output operating mode,
selected from the rear panel Fixed/Variable output
switch, allows you to change volume level by
rotating the knob. The volume down function
(counter-clockwise rotation) is very rapid and allows
quick changes in the volume level. Volume up
(clockwise rotation) functions rapidly up to a
displayed volume level of 65.0.
Input Selection Mode:
Pressing the control knob in briefly will toggle into
the input selection mode. The selected input will be
displayed for 5 seconds. During this time you can
rotate the control knob to scroll to the desired input.
Pressing the knob again will select the indicated
input. The volume level will automatically ramp down
and up during this selection process. If the control
knob is not pressed for 5 seconds, the indicated
input will automatically be selected and the DAC1.5
will return to the default volume control mode. Inputs
are indicated as: AES, SP1 (SPDIF1), SP2
(SPDIF2), OPT (TOSLINK), and USB.
The sonic performance of the DAC1.5 will begin to stabilize after 100 hours of continuous power up.
Fixed Output Operating Mode:
Pressing the rear panel Fixed/Variable Output switch
to the in position will set the DAC1.5 in a fixed output
operating mode. This mode is used when driving an
analog preamp or integrated amplifier input. The
volume control function is then provided by the
associated preamplifier or integrated amplifier.
To use the Fixed Ouput mode set the ouput level to
100.0 for a 2 Vrms maximum level from the RCA
outputs or 4 Vrms level for the Balanced XLR
outputs. If you want the outputs set for a lower level
then set the volume control to a lower level. For
example, for about 2 Vrms out from the balanced
outputs set the volume control to 94.0. This will
represent about a 2 Vrms output level on the
balanced outputs. When the level is set then press
the rear panel Fixed/Variable Output button. The
front panel display will now show the selected input.
Rotating the knob will scroll to different inputs and
the Volume and Mute functions on the remote will
not function.
Front Panel Digital Lock Indicator:
When no digital input signal is present on an input
the first decimal point on the display will blink on and
off. For example the display will show: 65.0
and the first decimal point will be slowly blinking. If
this occurs you need to check that the correct input
is selected and then check that the digital source
is connected, active and functioning correctly.
