Front Panel Control Knob:
The control knob is a continuously rotat-
ing control with a push-switch function.
Standby Mode:
Pressing and holding the control knob
for 2 seconds will take the PRe3 out of
Standby and in to operating mode. The
unit will come up in a soft mute mode.
The operating input will be indicated for
several seconds and then it will go to the
volume control mode. To place the PRe3
in Standby mode press and hold the
control knob for 2 seconds.
Volume Control Mode:
The PRe3 default operating mode 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 vol-
ume level of 50.0. There is a pause at
50.0 until the display dims then the vol-
ume up function continues more slowly
to a displayed value of 60.0 and then
slower yet above 60.0. This operation
makes it difficult to accidentally set a vol-
ume level that is too high.
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 indicat-
ed input will automatically be selected
and the PRe3 will return to the default
volume control mode.
Home Theater Bypass Operation:
Input 5 can be set to a home theater
bypass mode (htb) that is used to pass
the front left/right outputs from a multi-
channel processor output through the
PRe3 to the main L/R power amplifiers.
This mode must be used with a
preamp output which has volume
control function as the PRe3 vol-
ume and mute controls will not
function while the PRe3 remains
in the htb unity gain setting.
When in the Input Selection Mode, Input
5 can be toggled between the normal
operting mode (In 5) and the bypass
mode for (htb5) by pressing the control
knob 2 times. You will note that the Input
display will toggle between htb5 and In
5. The display simply reads htb (home
theater bypass) when the bypass mode
is active.
