OPERATINGTHE STANDARD PREAMPLIFIER
Front Panel Controls:
Althoughmostof thefront panel controls (Volume,Power,Mute) areself 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 adiscrete, pure
tube phono preamplifier,providing37 dB of gain,suitable for use with MM (moving
magnet) and many high-output MC (movingcoil) cartridges.Your VACdealer can
recommend the proper phono cartridge(s).
Phono Section MC (option): Asabove,this will be fitted to “L6",and provides
approximately 60 dB ofgain.Itshould not be used with highoutput pickups,which may
generate excessivedistortion.Your VACdealers 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”(hometheaterpass-throughmode).Inthe“Source”
position,inputselection is determined by theSource SelectorSwitch.Inthe “Tape”position,
the Source Selector is overridden,and the Tape inputsare activated.[Important: The
StandardPreamplifier isoutfitted withafull “tape loop”,includingaline leveltape inputand
afixed level recordingoutput.Inaddition to drivingthe recordinginputs of atape deck,this
output can supply signal to any typical line level input,enablingit to control asecond zone
in multi roominstallations.]
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 atypical preamplifier.
Rotatingthe control clockwise to the “Cinema” position bypasses all preamplifier controls
(includingvolume) and passes the output fromyour surround sound processor (i.e., the front
left-and right-channeloutputs ofamultichannel processor)directly to yourpower amplifier.
Inthis case,the users’ analogstereo 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 RCAjackslabeled “HomeTheater Direct”. When the control is set to the “Cinema”
position,the Standard functions as apass-throughONLY,and is controlled by the external
processor,preamplifier,or othercomponent connectedto the“HomeTheater Direct” inputs.
Mute: On units without remote control,this is atwo position switch.Inthe “Mute” position,
signal is blocked fromleavingthe preamplifier.Note: Mute is automatically engaged when
switchingon units equipped with the remote control option.
On units with remote control,this knob is springloaded; movingthe control clockwise will
