Rear Panel Features
1. AC Line Cord
This is heavy-duty cord capable of
carrying large currents required by high-
power amplifiers. The Classic itself
requires only modest power (equivalent to
most light bulbs) and may thus be pow-
ered by a conventional extension cord if
required. But if you have substantial
power amplifiers connected to one of the
convenience outlets, only use a heavy
duty extension cord (16 gauge or thicker).
The line cord should only be plugged in
after completing all input and output
connections to other components.
2. Fuse
Always unplug the power cord
before inspecting or changing the
fuse. Never use a fuse with a
larger current rating than 2 A.
3. Accessory outlets
These three unswitched AC outlets are
LIVE whenever the unit’s line cord is
plugged into an active AC receptacle.
They can be used to supply AC power to
other components of your system,
including your amplifier. The total power
draw must not exceed 1000W.
Verify that all component power-switches
are OFF before plugging any component
line cords into these or any AC outlets.
If your power amp is not equipped with a
power switch, make sure that the
preamplifier’s power switch is OFF
(indicator LED is not lit) and its AC line-
cord is unplugged, before connecting the
power amp’s line cord to one of the
Classic’s outlets.
4. Balanced outputs
These are the left and right outputs which
connect to the balanced inputs of an
amplifier used to drive your speakers.
Balanced outputs offer superior noise
cancellation, especially if there is a long
cable run to your amplifier.
5. Main 1 and Main 2 outputs
MAIN 1 - These are left and right unbal-
anced (RCA) outputs which connect to
the unbalanced inputs of an amplifier
used to drive your main front speakers.
MAIN 2 - Identical to Main 1. They can be
used to drive a second power amplifier,
such as in bi-wire or multiple speaker
applications, to drive a subwoofer, or to
feed processed signals to a tape recorder
or a time-delay accessory.
