Operating the D2
Operation of the D2 is very straightforward, but there are a few points worth noting
which, once understood, will make using the unit even easier.
Switching the unit on and start-up procedure
After plugging in the power and switching the power on suing the rear panel switch,
confirmation is quickly given that all is well by various status LEDs illuminating almost
immediately after power-up. These will include, as a minimum, METER (In/Out);
MODE (Cut Above/Below); and Band Active LEDs .
The gain reduction will fully illuminate and, after the bypass relays disengage, begin to
‘count down’ accompanied by the output level fading up to normal operating level.
The entire process is complete when the input/output meters and gain reduction
begin to operate normally. This whole start-up procedure only takes a few seconds.
Press-and-hold Keys
The legending on the front panel alerts the user to the fact that several keys require a
‘press and hold’ action to initiate them.
These keys relate to functions that could
accidentally introduce large changes of level
at the outputs, causing undesirable effects
and possible damage. These keys have their
function marked in BOLD (and a different
font) to make it clear that they will only
change state if the key is held in for a time.
The keys in question are…
MODE –switching between ‘cut below’ mode and ‘cut above’ mode (See page nn)
LISTEN –switching output to monitor any band’s sidechain EQ signal (See page nn)
FULL RANGE–switching middle band into full range mode (See page nn)
Minimum and maximum control positions To ensure that the D2 is 100% accurate
all of the time, and that what it says on the
front panel is exactly what the unit is
doing, it has been necessary to introduce
‘end-stops’ on the controls.
The extreme regions on each control
marked with the curved line designate this
entire region as relating to the parameter
value shown. This is to compensate for the mechanical tolerances of the
potentiometers.
