PHONO SELECTOR (Cartridge Selection / Subsonic
Filter Switch)
Set this switch to correspond to the type of cartridge
(MC or MM) used on your record player. The switch also
features positions for activating the subsonic filter,
effectively suppressing ultra-low frequencies generated
by motor vibrations from the record player and warped
records. Such ultra-low (subsonic) frequencies could
easily damage your speakers.
e MM: Use this position when an MM cartridge is
used on the player connected to the PHONO
input jacks.
Use this position when an MC cartridge is used
on the player connected to the PHONO input
jacks.
e SUBSONIC-MC: Use this position to eliminate sub-
sonic frequencies when an MC cartridge is used.
e SUBSONIC-MM: Used this position to eliminate
subsonic frequencies when an MM cartridge is used.
VARIABLE LOUDNESS (Loudness Control)
At low volumes, the human ear is less sensitive to low
and high frequencies. Use this control to compensate
for this deficiency when listening at low volume levels.
Turn this control counter-clockwise until a natural
balance of bass and treble sound has been restored.
BALANCE (Balance control)
The balance between left and right channels is adjusted
by using this knob.
When it is set to the center position, the amplifier gain is
the same for the left and the right.
If there seems to be a difference in the left and right
channel output voltages for the cartridge, try moving
the knob to the left and the right to adjust it. If the
volume on the right side is too low, turn the knob to the
right. If the volume on the left side is too low, turn the
knob to the left.
NOTES ON INSTALLING THE PRE-AMPLIFIER
To prevent harmful influence caused by heat build-up and
electric radiation from the power amplifier or externally
induced humming, preferably install the pre-amplifier next to
the power amplifier. If such an installation is not possible, be
sure there is a free space of 15 cm or more between the
pre-amplifier and power amplifier or other system compo-
nent.

NOTES ON CONNECTION
Do not plug the power cord into the AC wall outlet until afl
connections have been completed.
Make sure channels are correctly connected. Connect Left
channels to Left channels and Right channels to Right
channels. Follow the color markings of pluys and terminals
to make sure mistakes are not made.
Connect all pin-plugs securely, pushing thern completly
into the jacks. Incomplete connections will cause noise
generation.
Binding the connection cables to power cords, or running
such cables close to power supply transfomers will cause
humming or noise, and should thus be avoided.
The PHONO input jacks are extremely sensitive. Avoid
using the power amplifier if no connectionhas been made
to these jacks, as this otherwise may caus low humming
from the speakers when the power-ampifier is on.
