Commentary
A cassette deck with a mixer function.
There are four inputs, four microphone inputs on the front, four line inputs on the rear, and a full-scale active mixer amplifier using an operational amplifier for full-scale mixing recording.
If you use the microphone and line simultaneously on the same channel, the microphone input takes priority.
Two of the four input channels (ch2 and ch3) are equipped with a pan-pot function that can control sound image localization.
Two systems with pan pots are equipped with low-cut filters to prevent proximity effects.
Only the mixer section can be used independently.
In addition to the line output, it is equipped with a mixing out (2 ch) that can directly take out the output of the mixer.
The drive motor is equipped with a DC servo motor with a tacho generator.
Three levels of bias and equalizer can be selected.
To minimize the processing of the source sound during recording, the noise reduction device uses a dynamic noise limiter (DNL) that is effective only during playback.
Equipped with a limiter for excessive input.
It is equipped with a fader with a master volume function that can raise and lower the volume of all channels simultaneously.
Equipped with a large peak level meter.
Uses a feather touch stop button that uses a plunger.
Hard permalloy head is used for the head.
