Connection
Before
turning
on
the
device
,
please
carefully
confirm
that
the
load
is
constant-voltage
or
constant-impedance
speakers
and
set
the
amplifier
to
the
corresponding
output
mode
.
It
is
forbidden
to
switch
the
constant
voltage
and
constant
impedance
state
arbitrarily
when
the
power
is
on
.
Constant voltage mode: Turn the switches
corresponding
to
CH1/CH2: 4-16
Ω
and CH3/CH4:
4-16
Ω
to OFF.
Constant impedance mode: Turn the switches
corresponding
to CH1/CH2: 4-16
Ω
and CH3/CH4:
4-16
Ω
to ON.
The
operation
method
is
as
follows
:
①
When
the
100V
and
speaker
output
mode
selection
switch
is
set
to
the
100V
position
,
as
shown
in
the
figure
below
:
4-16
Ω
②
When
the
100V
and
speaker
output
mode
selection
switch
is
set
to
the
4-16
Ω
position
,
as
shown
in
the
figure
below
:
4-16
Ω
