Balanced XLR input and operation
The balanced mode can only be used if the preamplifier has a balanced output. In order to
use the balanced XLR- input, turn off the amplifier, and remove the shorting plugs from
the negative (-) RCA inputs.Use an XLR interconnect with GND on pin 1, + on pin 2 and -
on pin 3.
Balanced RCA input and operation
The balanced mode can only be used if the preamplifier has a balanced RCA output. Be
sure the amplifier is turned off. Remove the shorting plugs. Use 2 single (1 stereo)
interconnect cables from the preamplifier to each channel of the power amplifier, connec-
ting + and - outputs from the preamplifier to the + and - inputs of the corresponding
channel on the amplifier.
Make sure the + and - are not interchanged, as this will cause the system to operate out of
phase, with very poor bass response as a result.
Operating instructions:
How to turn on your system
You should always turn on your equipment in this order: Signal source devices (CD, tuner,
etc) and preamplifier are turned on first. Allow 30 seconds of preheating before you turn on
your power amplifier.When turning your system off, you should start by switching off your
power amplifier, then the preamplifier, and finally your signal source devices
After switching on the power amplifier, there will be a 5 seconds delay before the speakers
are connected. This will prevent large turn on/off transients to reach the speakers.
Replacing a blown main fuse:
Always remove the AC cord from the Inlet
The main fuse is located inside a small drawer in the AC inlet of the unit. If, for some
reason the fuse blows, turn the unit off, and remove the AC cord from the inlet.
Open the drawer with a small screwdriver and remove the broken fuse. The spare fuse is
located in the hole in front of the main fuse. Push the new fuse gently out of the hole, and
place it in correct position (where the blown fuse was removed). Push the drawer gently
back to the closed position, connect the power cord and turn the unit on.
Never replace a blown fuse with other values than printed on the unit.
