Sony XM-404EQX - Manuel (Page 3)

Features
• Maximum p(m’cr (H3t|iut of 80 watts per channel (at
4 ohms).
• Tliis unit can be used as a bridging amplifier with a
maximum output of 200 watts.
• Direct connections can be made with the speaker
outputs of your car audio if it is not equipped with
the line output (High level input connection).
• Low-pass filter, high-pass filter, and five band
equalizer circuit are built-in.
• The DIRECT switch can be used to bypass the low-
pass filter, high-pass filter, and equalizer circuit for
more enjoyable high quality sound.
• You can visually confirm the output level of both the
left and right sides with the power level indicator.
• Protection circuit and indicator provided.
• Pulse power supply* for stable, regulated output
power.
Pulse power supply
This unit has a built-in power rc^^ulatur which converts the
poieer supplied b\/ the DC 12 V car battery into hi^h speed
pulses a semiconductor switch. These pulses are
stepped up by the built-in pulse transformer and separated
into both positive and negative power supplies before being
converted into direct current again. This is to regulate
fluctuating voltage from the car battery. This light weight
power supply system provides a highly efficient power supply
until a low impedance output.

Location and Function of Controls
[H POWER/PROTECTOR indicator
• OVER CURRENT lights up green during normal
operation. The color will change from green to red when
receiving a powerful signal.
• OFF SET lights up green during normal operation. The
color will change from green to red when the voltage
going out to the speaker terminal or the pin jack is too
high .
• THERMAL lights up green during normal operation.
The color will change from green to red when the
temperature rises to an unsafe level. 'The color will return
to green when the temperature returns to normal.
¡ 2 } Power level indicator
Indicates the output levels of both the left and right sides. The scale is
calibrated for use with 4 ohm speakers. .
[U DIRECT switch
When the DIRECT switch is set to ON, the signal does not go through the
low-pass filter, high-pass filter and equalizer circuit.
[4] LEVEL adjustment control
Tlie input level can be adjusted with this control when using source
equipment made by other manufacturers. Turn it to MAX when the
output level oi the car audio seems low. To reduce noise, turn the LEVEL
control (gain) of the amplifer to MIN and the volume of the car audio up.
[5] FILTER selector switch
When the switch is in the LPF position, the filter is set to low-pass. When in
the FTPE position, the filter is set to high-pass. When the DIRECT switch is set
to ON, these filters do not work.
[6] Cut-off frequency adjustment control
Sets the cut-off frequency (50-200 Hz) for the low-pass or high-pass filters.
[7] EQUALIZER level control
You can change the settings of the five band (50 Hz, 200 Hz, 800 Hz, 3.2 kHz,
12.8 kHz) equalizer.
Switch settings for each system configuration
(Change the switch positions according to the configuration.)
