OPERATING THE STANDARD PREAMPLIFIER

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:

Phono Section MM (option): When fitted, input “L6" will be connected to a discrete, pure
tube  phono  preamplifier,  providing  37  dB  of  gain,  suitable  for  use  with  MM  (moving
magnet)  and  many  high-output  MC  (moving  coil)  cartridges.  Your  VAC  dealer  can
recommend the proper phono cartridge(s).

Phono  Section  MC  (option):  As  above,  this  will  be  fitted  to  “L6",  and  provides
approximately 60 dB of gain. It should not be used with high output pickups, which may
generate  excessive  distortion.  Your  VAC  dealers  can  recommend  the  proper  phono
cartridge(s).

Monitor:  The  small  knob  found  at  the  lower  left-hand  corner  of  the  faceplate  switches
between  “Source”,  “Tape”,  and  “Cinema”  (home  theater  pass-through  mode).  In  the
“Source”  position,  input  selection  is  determined  by  the  Source  Selector  Switch.  In  the
“Tape”  position,  the  Source  Selector  is  overridden,  and  the  Tape  inputs  are  activated.
[Important: The Standard Preamplifier is outfitted with a full “tape loop”, including a line
level tape input and a fixed level recording output. In addition to driving the recording
inputs of a tape deck, this output can supply signal to any typical line level input, enabling
it to control a second zone in multi room installations.]

The “Cinema” position provides access to one of the Standard Preamplifier’s most unusual
feature. When set in the “Source” position, input choice is governed by the Input Selector
switch. This is the normal setting, and enables the unit to be used as a typical preamplifier.
Rotating the control clockwise to the “Cinema” position bypasses all preamplifier controls
(including volume) and passes the output from your surround sound processor (i.e., the front
left- and right-channel outputs of a multichannel processor) directly to your power amplifier.
In this case, the users’ analog stereo sources would be connected, as usual, to the line, phono
and tape inputs. A/V inputs (DVD, Laserdisc, DSS, etc.) would be connected to the home
theater processor, and the processor’s main outputs would be connected to the pair of rear
panel RCA jacks labeled “Home Theater Direct”. When the control is set to the “Cinema”
position, the Standard functions as a pass-through ONLY, and is controlled by the external
processor, preamplifier, or other component connected to the “Home Theater Direct” inputs.

Mute: On units without remote control, this is a two position switch. In the “Mute” position,
signal is blocked from leaving the preamplifier. Note: Mute is automatically engaged when
switching on units equipped with the remote control option.
