Commentary
Dolby HX Pro and 5-band spectrum level meter are recorded and re-auto reverse deck.
By using super-bias and shifting the bias frequency to a higher band, more accurate recording of digital sound with frequency components close to the limits of the audible band is achieved.
This circuit is equipped with Dolby HX Pro. By analyzing and controlling the music signal in units of 1/1000 second, the effective bias amount is always maintained in the optimum state. This circuit greatly improves the MOL characteristic of the high-frequency range, and enables clearer recording of the high-frequency signal that rises steeply.
Equipped with a 5-band spectrum level meter by FL tube.
Displays the real-time level with 100Hz/300Hz/1kHz/3kHz/10kHz as the center frequency.
The spectrum level meter allows for severe bias and recording level adjustment.
When the calibration button is pressed, a series of operations is automatically performed : recording the combined signal of high and low two frequencies of the built-in oscillator for about 10 seconds → rewinding to the recording start position → playing the recorded signal → rewinding.
Simply adjust the bias adjustment knob and recording level knob to the reference point indicated on the spectrum level meter during playback.
An LC-OFC wound laser amorphous head is used for the recording / reproducing head.
Equipped with Dolby NR B-C type.
Equipped with quick auto-reverse function.
Built-in functions such as AMS / blank screen, music scan function, autoplay, counter-linked memory stop / play, etc.
Equipped with linear electronic counter with subtraction function of minute and second display.
Equipped with Type I/II/IV auto tape selector.
Equipped with Rec Mute with auto space.
By the timer sold separately, it is possible to record the absence and play the alarm clock.
Equipped with a headphone port with variable output.
The included wireless remote control can be combined with a Sony remote-controlled CD player to create a synchronized remote control that synchronizes the timing of recording and playing without connecting a sync cord.
