Commentary
A stereo cassette receiver equipped with an adres as a noise reduction system.
An adres is installed as a noise reduction system.
For adresing, the hissing associated with the cassette can be reduced to less than 1 / 30th (10 khz), and the dynamic range can be expanded to more than 100 db (1 khz).
When an adres is used, the recording level is manual. Otherwise, the recording level is ALC (automatic recording level).
The cassette deck is compatible with metal tape and uses 2-motor IC logic mechanism.
Remote control unit is also supported.
It is equipped with functions such as MQSS (Music Quick Selector System), one touch recording, pause / mute, timer standby, auto-repeat, and so on.
The tuner section uses a digital display system that displays the received frequency numerically, and the green LED lights up to indicate the tuning point.
The amplifier is equipped with a loudness circuit, push-tone control, aux and rec out jacks, and microphone mixing is also available.
