Commentary
A twin recording re-reverse deck equipped with Dolby S NR and various functions.
Equipped with Dolby S NR as a noise reduction system.
The Dolby S uses Dolby SR (Spectrum Recording) technology, which is used in movie film sound production. By performing precise signal processing, noise is reduced to approximately 1/16 (24 dB). In addition, the Dolby S is well aware of the breathing phenomenon unique to noise reduction. By finely controlling the pitch and pitch of sound, there is little variation in sound quality, and dynamic sound can be recorded naturally.
In addition, Sony's semiconductor technology makes it into a single chip, and high-density packaging technology makes it into a module with peripheral parts, resulting in high noise reduction and improved sound quality.
Equipped with the Dolby HX-PRO, the bias current, which is normally fixed, is controlled to an optimum value in units of one thousandth of a second according to the frequency and level of the signal, thereby maintaining linearity in the high frequency range.
Equipped with an auto-calibration function that automatically sets the recording condition to match the tape to be used.
Equipped with a CD sync recording function, you can easily record from a CD by pairing it with a Sony remote-controlled CD player.
If you press the CD sync button on the remote control provided with the deck, the deck will start recording from the pause state and the CD will start playing a little later.
Equipped with an FL digital counter.
It is equipped with a peak level meter that can display the peak value of the audio signal in real time and also has a peak hold function.
It is equipped with multi-AMS function which is further advanced from AMS function.
With this function, you can start up to 30 songs before and after the current tape position.
A deck is equipped with RMS (Random Music Sensor).
With this function, you can select only the songs you want to listen to regardless of whether they are on the A side or the B side of the tape, and program the order of the songs freely and play them.
Equipped with REC mute function with auto space, when recording or recording pause, the unrecorded part for approximately 4 seconds is automatically recorded to the tape with a single button, and it waits in the recording pause state.
Wireless remote control is included.
