STEREO POWER AMPLIFIER M-10X
How to connect speakers
(Stereo connection)
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
speaker terminal
!
(red) of this unit, and the
@
terminal of the
speaker system to the speaker terminal
@
(black) 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; thus, normal stereo playback will not be achieved.
(BTL connection)
When BTL (MONO) is selected, this unit turns into a monaural
power amplifier, and if stereo playback is desired, another
M-10X is required.
Connect the left-channel speaker to the left speaker termi-
nal of an M-10X and the right-channel speaker to the right
speaker terminal of M-10X. Securely connect the
!
termi-
nal of the speaker system to the red SPEAKERS L terminal
(BTL
!
) of this unit, and the
@
terminal of the speaker system
to the red SPEAKERS R terminal (BTL
@
) of this unit.
• Do not bring the core wire of the speaker cable into con-
tact with the core wires of other speaker cables or the
metal parts of this unit. Failure to observe this may cause a
malfunction of this unit or the speakers.
• When the power of this unit is set to on, do not touch the
metal parts of the terminals or the core wires of the cables.
Failure to observe this may result in an electric shock.
• Use extra care not to connect in reverse polarity or reverse
right/left channel to perform normal stereo playback.
Some speaker selection switch boxes have the
@
speaker
terminal connected to the common ground terminal. When
BTL (MONO) is selected, the inverted output side of this unit
is short-circuited to the common ground and excessive cur-
rent flows into this unit. The protection circuit is activated,
which may cause a breakdown. Therefore, do not use such
a switch box. When BTL (MONO) is selected, this unit shall
be directly connected to speaker systems, or the switch box
with which the
@
speaker terminal can be independently
selected shall be used.
When this unit is connected to an input device or a speaker
system, turn off the main power button of this unit or turn
this unit to standby to protect the amplifier and speakers
from excessive input.
After connection, ensure that connections are appropriately
performed and turn this unit to operating.
NOTE:
• This symbol that touching uninsulated termi-
nals or wiring may result in an unpleasant sen-
sation.
• Before connecting to speakers, turn off the
main power switch.
