FEATURES
The TA-AX44 integrated stereo amplifier incorporates a number of
technical breakthroughs in circuit design. On its attractive front
panel most of the controls and switches are "touch pad" switches
and the tone, filter and volume settings are shown by fluorescent
displays.
HIGHLIGHTS OF THE
ASP (Audio Signal Processor) IC in the preamplifier stage
Sony has developed a new audio device, called the Audio Signal
Processor
which can digitally control the tone, filter and volume
settings. The ASP
tion. Mechanical controls and switches have been practically
eliminated from the front panel. In combination with a microcom-
puter and a non-volatile memory IC, the ASP IC offers greater flex-
ibility
an Acoustic Function, an ability to store and recall two
sets of tonal adjustments.
Legato linear power amplifier stage
The operation of the power amplifier stage is stable without any
observable distortion up through the higher frequencies. We call
this power amp "Legato Linear" because its switching distortion is
very low and its output waveform smooth.
Simple, straight signal path layout
A heat-pipe cooling system and the ASP
and output terminals minimize wiring losses and allow low distor-

OPERATING VOLTAGE
Before connecting the unit to the power source, check that the
operating voltage of your unit is the same as the local power line
voltage.
The Continental European model (AEP model) operates on 220 V
ac (or 240 V ac adjustable by authorized Sony personnel).
The United Kingdom model (UK model) operates on 240 V ac (or
220 V ac adjustable by authorized Sony personnel).
The model for other countries (E model) operates on either 120,
220 or 240 V ac. The voltage selector is located on the rear
panel. If the selector must be reset, disconnect the ac power
cord and turn the selector with a coin so that the arrow mark
of the selector points to the proper voltage figure.
The US, Canadian model operates on 120 V ac.
