Stereo Integrated Amplifier (1983-85)
The TA-V7 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.
The Audio Signal Processor IC developed by Sony can digitally control the tone, filter and volume settings. The ASP IC also permits electronic program source selection. Mechanical controls and switches have been practically eliminated from the front panel.
In combination with a microcomputer and a non-volatile memory IC, the ASP IC offers greater flexibility - an Acoustic Function, an ability to store and recall two sets of tonal adjustments.
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.
A heat-pipe cooling system and the ASP IC layout near the input and output terminals minimize wiring losses and allow low distortion operation.
Independent CD inputs are provided to connect a brand new CD player to your stereo system.
Using the optional ST-V7/V7L system control tuner, various operations - power on/off, program selection, acoustic setting selection, muting on/off and volume adjustment - can be remotely controlled.
