5. OPERATION
Connect the mains cable to a mains outlet.
Once you have finished connecting all components,
you can power on the Project Two Mk2 with the
mains switch
O / I
(26.).
The volume control will then automatically turn
counter-clockwise and, for a while, the STANDBY
LED will blink red/green, after which it will remain
red.
The pre-amp is now in standby mode.
Power on
You switch the amp on with the STANDBY button.
That way, all circuits will remain at optimum
operating temperatures and the audio quality will be
100% immediately after switching on. Additionally it
significantly increases the life span of the
component.
The pre-amp will select the CD SYM input after
which it un-mutes the output.
Selecting an input
You select the input with the large rotary knob
INPUT:
clockwise
to the right of the selected one,
anti-clockwise
to the left of the selected one.
Upon reaching LINE 3 or CD SYM you cannot 'roll
over' to CD SYM or LINE 3 respectively.
As long as you move the knob, only the LED's will
change: the current selected input remains active.
The new input only becomes active after you have
selected it and released the INPUT knob.
You will hear a 'click'. This is caused by the precision
relays for the inputs: the 'old' one is released while
the new one is energised.
Adjusting the volume level
The large VOLUME control to the right adjusts the
volume level from OFF to maximum (fully clockwise).
The level change is immediate.
Memory mode
The Project Two Mk2 has a MEMORY mode: it
automatically selects the last input that was active
before you switched the component off with the
stand-by button.
Power off
You switch the Project Two Mk2 off (to stand-by)
with the STANDBY button (2.).
