Before connecting
Before connecting other devices, connect the jack side of the
accessory power cable to the AC inlet of this unit.
Before connection is made, turn off the main power switch
of this unit and the power of all other connected devices to
prevent accidents due to noises generated unexpectedly.
How to connect power supply
Use the accessory power cable and insert the AC plug in the
outlet on the wall in the room where the unit is installed.
How to connect a CD player, control
amplifier
Connect the output terminal of a control amplifier to the input
terminal with 2 (R and L) pin-plug cables.
When using a source device with the volume adjusting func-
tion, such as a CD player, connect to the VARIABLE input
terminal. When using a source device with the volume con-
trol, such as a control amplifier, connect to the DIRECT input
terminal.
Select DIRECT or VARIABLE input with the input selector.
How to connect speakers
Connect the left-channel speaker to the SPEAKERS-L
terminal of this unit and the right-channel speaker to the
SPEAKERS-R terminal.
Securely connect the
!
terminal of the speaker system to
the red speaker terminal (
!
4Ω,
!
8Ω, or
!
16Ω) of this unit
according to the impedance of the speakers to be used and
the
@
terminal of the speaker system to the black speaker
terminal (
@
COMMON) of this unit.
If the
!
or
@
terminal is reversely connected to either of the
right or left of the speaker system, the signal phases repro-
duced from the right and left of the speaker system are also
reversed. In such a case, be aware that the sound level in
the low range will be reduced and the acoustic stability will
worsen, and thus the normal stereo playback is not achieved.
If the impedance of the speakers to be used is other than 4Ω,
8Ω, or 16Ω, connect the terminal with an impedance closest
to the impedance value of the speakers.
The range of the impedance of the speaker to be connected
should be within the range of 4Ω to 16Ω.
