You can operate the various controls and buttons from the front panel to access the full
functionality of this unit, and the operational functionality can also be accessed via the
remote control. The indication LEDs show the various operating modes of the unit.
1. The
Power
button is used to turn the preamplifier on and off. If the unit is powered off
press the button to turn the preamplifier ON and press the button down again to turn
the unit OFF. The
Power
LED will blink blue during warmup, remain on steady blue
after power up, and turn off during power off or standby.
2. The
Input Select
buttons are used to select the source component for the preamplifier.
Any of the inputs can be selected by pressing the appropriate selector button labeled
with the selection of your choice. The input selectors are grouped by function: The
first two from left to right can be configured as either balanced or single ended inputs.
During power up these two buttons also double as trigger programming buttons
(when not in locked mode).
If triggers are programmed the first two input LEDs flash red during power up to
indicate trigger functions, and these two inputs can also be set for balanced (blue) or
single ended (green) operation.
The third input from the left is marked
Ph/Aux2
, and can be selected as either an
RIAA equalized phono input (if a phono card is installed in the unit), or as the input
that an external phono stage is connected to, or as a regular line input if there is no
phono stage. This input and the following four are single ended inputs only, and are
not used for any other function. The LED color is permanently green.
Warning
It is critical for proper sonic performance of this component that it be
properly configured for the type of connection and mode of operation: If a
balanced signal is applied to the input that input must be configured for balanced
operation, and vice-versa.
3. The
Tape
input is also usable as a normal (single ended only) input, with the additional
capability of handling the record monitor function. LED color is green for input, and
red for monitor.
4.
The
Mon/Proc
button is used to monitor the output when recording, and allows the
Tape
input to be routed to the preamplifier output while the selected input is routed to
the Record out, to monitor the recording at the desired volume level while keeping the
selected input connected to the Record Out at a fixed level.
The
Mon/Proc
button is also used to set any input for unity gain
(when not in locked
mode). This function
is used for routing an external surround processor to the front left
and right channels. In this mode, your external surround processor will control the levels of
all of the channels of your system, including the front left and right channels. In this mode
the preamplifier is in the unity gain mode, and the volume control is set to a fixed position
(equivalent to volume position 69 in single ended mode). The signal is passed to the front
left and right amplifiers through the gain stage of the preamplifier, but at the same volume
as the surround processor is putting out, and the preamplifier’s volume control is disabled.
