Bi-amplifier stereophonic reproduction
How to connect the input terminals to
input devices such as a CD player
When the output mode is set to the bi-amplifier output, only
the unbalanced input terminal is active as an input terminal of
this unit and no sound comes if the balanced input terminal
is connected.
Connect between the unbalanced output terminal of an input
device such as a CD player and the unbalanced input termi-
nal of this unit with a pin-plug cable.
At this moment, exercise extra care not to conduct wrong
connection between the right and left channels. If the right
and left channels are connected reversely, the localization of
sound images is deteriorated, thus failing in normal stereo
playback.
If the grounding of the pin-plug cables is inadequately con-
nected, noises including hum may be generated, resulting in
an adverse S/N ratio. Surely insert the connection plug.

The LINE-1 L terminal is provided for low frequency output of
the L channel, and the LINE-2 L terminal is provided for high
frequency output of the L channel. The LINE-1 R terminal is
provided for low frequency output of the R channel, and the
LINE-2 R terminal is provided for high frequency output of the
R channel.
The LINE-2 unbalanced output terminal that is the output for
high frequency can adjust the sound volume of up to ±6 dB
in steps of 1 dB with the preset operation of the supplied
remote control.
How to connect the remote output
terminal to a power amplifier
Connect between the remote input terminal of a power ampli-
fier such as Luxman M-900u and the remote output terminal
of this unit with the dedicated remote cable (no polarity) sup-
plied with the power amplifier.
After this connection, the power of the power amplifier can
be turned on and off in conjunction with the operation switch
of this unit.
Two (2) remote output terminals are available, and both ter-
minals provide the same signals. Use them according to your
taste.
Use the dedicated remote cable only for the connection be-
tween Luxman control amplifiers and Luxman power amplifi-
ers. Connection to such a terminal that the remote output of
this unit is short-circuited may cause a malfunction.
When this unit is connected to an output device, turn off the
main power switch of this unit or turn this unit to the standby
state to protect the amplifier and speakers from excessive
input. Also turn off the power of the input/output devices con-
nected to this unit. After connection, ensure that connections
are appropriately performed and turn this unit and the input/
output devices to the operating state.
