Commentary
Twin reverse deck equipped with random music sensor.
The A-deck is equipped with an RMS (Random Music Sensor) that can play the desired sequence of music on the tape. You can program up to 28 songs (14 songs on one side) randomly from both the A side and the B side of the tape.
It can also be used for dubbing. While the A deck is searching for a song, the B deck is on standby with a recording pause, and when playback starts on the A deck, the B deck is automatically in a recording state.
The B deck is equipped with an auto-calibration function that allows you to set the recording condition to match the tape with a single button so that you can record by taking full advantage of various tapes with different recording characteristics.
Both bias calibration, which adjusts the bias value during recording, and level calibration, which adjusts the level difference between recording and playback due to the difference in tape sensitivity, can be performed at the same time, making it easy to record according to the tape to be used.
In order to reduce hissing, both A and B decks (A deck is for playback only) are equipped with Dolby B/C NR that works simultaneously.
In addition, the B deck incorporates the Dolby HX-PRO, which controls the bias value in units of one thousandth of a second during recording to enhance linearity in the high-frequency range.
Both A and B decks are equipped with a multi-AMS (automatic music sensor) that can cue up to 30 songs before and after counting from the song currently being played.
For example, if you want to go back five songs and listen again, you can press the AMS button (←) six times, and if you want to listen to a song right after skipping two songs, you can simply press the AMS button (→) three times.
It is equipped with 3-mode tape running switching function of one way, repeat round trip (5 round trips) and relay. In addition, it is equipped with REC MUTE function with Oatley berth, auto tape selector which automatically determines the type of tape (normal, high position, metal), MPX filter switch which cuts the pilot signal in FM air check, 14-segment FL peak level meter, 4-digit tape counter with A/B deck independent reset function, stereo headphone terminal, etc.
Wireless remote controller with CD sync function is included.
