Commentary
A stereo cassette deck with Dolby NR.
The head uses an F & F (ferrite & ferrite) head with an all-ferrite structure that achieves abrasion resistance approximately 200 times that of permalloy and excellent characteristics.
In addition, by using a low-noise transistor in the first stage of the amplifier circuit, direct coupling with the head is realized, and elements such as capacitors are eliminated from the space between the head and the amplifier, improving SN ratio and frequency characteristics.
Equipped with Dolby NR system that can be turned on / off to reduce the hissing of the tape.
In addition, it is equipped with a 3-type tape selector.
Wow and flutter have been improved by adopting large 90 mm diameter flywheels.
Equipped with a ON/OFF Sony Limiter Recording switch.
In this recording method, manual recording is performed when an appropriate input is input, and a limiter circuit is activated when an unexpected large input is input to prevent distortion.
Built-in memory counter, peak indicator, auto-shutoff mechanism, lock-type pause button, line-out volume, MPX filter, etc.
Equipped with a mode indicator lamp.
The line and microphone can be mixed.
