●
Flow of PS4D/X4R signal line and power supply
controls
• Block diagram
The signal from the pin jack is converted into the differential
signal via the isolation amplifier, variable resistor, and single
end.
It is converted into the digital signal in the AD converter and
it is signal-conditioned in the DSP so that it can be amplified
by the PWM digital amplifier.
It is PWM-amplified to the analog signal by the driver and
power MOSFET to the level that can be output from the
speaker.
● Main signal amplifier circuit with PWM
• Main signal amplifier circuit with PWM
The audio signal that is DA-converted is converted into the
signal for PWM in the DSP.
Its level is shifted in the IC101 and it is converted into the
PWM signal whose amplitude is +/- B. The “+” side of the
amplitude is controlled by Q101 of the PchMOSFET and the
“-” side is controlled by Q103 of the NchMOSFET.
The signal right after this step is converted into the digital
signal in the AD converter and is feed-backed to the DSP.
The main signal is output from SP via the low pass filter.
In addition, current of the main signal is monitored in the
over current detection circuit and when the over current is
detected the output level is controlled by the DSP.
The signal for pre-out is output to the pin jack via the DA
converter used for the pre-out.
The 14V of the battery is converted to +/-40V in the SW
regulator. The voltage is controlled in the feed-forward and
anti-pumping circuits.
Over current is detected by R109 and R149. The signal level
is lowered in the DSP when the over current is detected.
Q107 is used to detect the “+” side of the switching current
and Q105 is used to detect the “-” side of the current.

CAUTION : For continued safety, replace safety critical components only with
manufacturer’s recommended parts (refer to parts list).
Indicates safety critical components. To reduce the risk of electric shock,
leakage-current or resistance measurements shall be carried out (exposed
parts are acceptably insulated from the supply circuit) before the appliance is
returned to the customer.
• DC voltages are as measured with a high impedance voltmeter. Values may
vary slightly due to variations between individual instruments or/and units.
