LEVEL: Input sensitivity adjustment control. Set to 1
position. Use a CD as source, increase head unit volume
until output distorts, then decrease volume by 1 step
in order to eliminate distortion. Turn LEVEL up until
sound becomes distorted, then turn LEVEL down a bit
for optimum sound.
REMOTE VOLUME CONTROL (ON - OFF): Activate ON or
deactivate OFF external remote volume control. Connect
external adjustment control to front panel proper
connectors.
SUBSONIC: (18 Hz ÷ 40 Hz): Crossover point (Hi-Pass filter)
adjustment. Rotating the knob you can select any frequency
between 18Hz and 40Hz. The frequencies below the
crossover point will be attenuated at 24dB/Oct. This control
is useful to remove ultra-low frequencies present in some
audio signals which do no contribute to music information
and might cause distortion or abnormal warming.
LO-PASS (40 Hz ÷ 150 Hz): Crossover point adjustment.
Rotating the knob you can select any frequency
between 40Hz and 150Hz. The frequencies above the
crossover point will be attenuated at 24dB/Oct.
PHASE (0°
÷
180°): Phase signal rotation point adjustment.
Rotating the knob you can select any phase angle
between 0° and 180° (phase reversal). The PHASE angle
is centered at 80Hz. For frequency beyond or below this
value, phase angle decrease. While listening to the front
loudspeaker (driven from other amplifier), adjust PHASE
in order to have a good bass response.
ON: Power LED. It lights up when you turn on the amplifier.
If all LEDs (6) (7) (8) (9) turn on at the same time, the
amplifier will shut down and you will have to contact a
service centre.
TH: Terminal status LED. It lights up when thermal
protection is active, above 85°C. The amplifier shuts
down until the chassis temperature goes below 75°C.
OVL: Overload status LED. It lights up when overload
occurs on the power output terminals. The amplifier goes in
muting for 3 seconds and this LED starts flashing until you
turn off the amplifier. REMOVE THE CAUSE OF OVERLOAD.
SPK: Speaker status LED. It lights up when a speaker
touches the car body. The amplifier goes in muting for
3 seconds and this LED starts flashing until you turn
off the amplifier.
REMOVE THE CONTACT BETWEEN SPEAKER WIRE AND
CAR BODY.
