FRONT PANEL CONTROLS
Although most of the front panel controls (Volume, Power, Mute) are self explanatory, VAC
has outfitted this unit with several advanced features which bear further description:
Mute: Toggles between the "Mute" and "Operate" condition. When muted, the
indicator light is illuminated.
Power: Turns the unit off and on.
Phono: Selects between the MM and MC inputs. Overall phono function is selected
with the main Selector switch (phono is one click counterclockwise from “1”
or one click clockwise from “6”).
The MM input provides 44 dB of gain, suitable for use with MM (moving
magnet) and many high-output MC (moving coil) cartridges. The MC input has
64 dB of gain, making it suitable for most low output cartridges. Both MM and
MC may be connected in the same system, so that in essence there are two
phono inputs.
Selector: This switch selects between IN1 through IN6 and the PHONO inputs. Rotate
counterclockwise to move down through the inputs, clockwise to move up
through the inputs.
Volume: Controls the output level for the PHONO input, and any line input set to the
“VAR” LEVEL mode.
Tape: This switch selects between the signal coming from the main selector (light
out) or the signal connected to the “TAPE IN” jacks (light on).
Cinema: This switch selects the source connected to the “CINEMA” input jacks.
Level: This switch allows any input (except Phono) to be level controlled by the
VOLUME control, or to be produced at a SET (fixed) level. To set this function,
hold the toggle switch in the direction of the desired setting for five seconds,
until the indicator light changes from blinking to solid illumination.
In the VARIABLE mode, the Phi functions like a conventional preamplifier.
The SET mode allows the control of volume to be determined entirely by the
source component. This is useful when the Phi 2.0 is being used as an element
of a multichannel or home theater system, with the level of all 5.1 channels
