PROTECTION
CIRCUITRY
The
protection
circuitry
may
have
operated
if
either
of
the
following
conditions
is
noticed:
*No
sound
is
heard
when
the
power
is
switched
ON.
*Sound
stops
during
a
performance.
The
function
of
this
circuitry
is
to
prevent
circuitry
damage
if,
for
example,
the
positive
and
negative
speaker
connection
wires
are
“shorted”,
or
if
speaker
systems
with
an
impedance
less
than
the
indicated
rated
impedance
of
this
unit
are
used.
If
this
occurs,
follow
the
procedure
outlined
below:
1.
Switch
OFF
the
power.
2.
Determine
the
cause
of
the
problem
and
correct
it.
3.
Switch
ON
the
power
once
again.
Note:
When
the
protection
circuitry
functions,
the
unit
will
not
operate
unless
the
power
is
first
switched
OFF
and
then
ON
again.

SU-G50
[1] Power switch (power)
[2] Peak-power indicators (power level)
These indicators indicate the peak power value of the output
level to the speaker systems.
[3] Input selector/volume level display (input)
This display usually shows the sound source selected by the
input selectors; when the volume-control is used to adjust
the volume level, the level is displayed in decibel for about
two seconds, after which the display returns again to indica-
tion of the sound source.
[4] Muting indicator ({mute| )
This indicator will illuminate when the muting button on the
remote-control transmitter (not included) is pressed. (Refer
to the operating instructions of the component with which
the remote-control unit is included.)
To cancel the muting function without using the remote-con-
trol transmitter, press and hold the ‘‘phono” input selector of
this unit for about 4 seconds.
Note:
The unit will switch to the phono mode.
[5] Volume indicator (volume level)
Indicates the volume output level at a glance.
Super bass switch/indicator (super bass)
Low frequency sounds are reinforced when this switch is
pressed.
The indicator will illuminate.
Volume control (volume)
Input selectors/indicators (input selector)
These selectors are used to select the sound source to be
heard, such as a disc, radio broadcasts, etc. The correspon-
ding input selector indicator illuminates during operation to
indicate the selected sound source.
The selected sound source is also displayed on the input
selector/volume level display.
[9] Balance control (balance)
This control is used to adjust the left/right volume balance.
VCR 1-monitor switch/indicator (monitor)
Set this switch to the ON position (so that the indicator above
is illuminated) when using a graphic equalizer o, playing
back or monitoring the sound from a VCR connecied to the
“VCR 1/EQ” terminals. This selector should be set to the
OFF position (indicator off) at all other times.
[14] Tone controls (bass/treble)
The bass control is used to adjust the low-frequency sound
range, and the treble control is used to adjust tihe high-
frequency sound range.
[12] Speaker selectors (speakers)
These selectors are used to turn the speaker system S on and
off.
