SANSUI P-M7

Commentary

A full-auto quartz DD player with an automatic random selection mechanism.

Equipped with a random program automatic music selection mechanism, you can play freely according to the programmed order of songs. You can play up to 7 songs in the program, and you can play repeatedly as many times as you like with the repeat function.
This automatic random program selection mechanism is achieved by two computer sensors attached to the tip of the tone arm. First, the first sensor searches between songs on the record board and tells the computer to gently lower the arm. Second, the second sensor senses that there is a needle point between songs and tells the computer to cancel muting. This dual sensor system enables accurate program selection.

It is equipped with an auto-select function that can automatically set the record size and rotation speed. It automatically detects any record size of 30 cm, 25 cm or 17 cm, and automatically selects 33 1/3rpm for 30 cm and 45 rpm for 17 cm at the same time as the auto-select board.
This function also functions as a safety mechanism to prevent the needle tip from being damaged by forgetting to place a record.

A quartz PLL servo DD coreless motor is used as the drive motor to achieve high rotational accuracy.

The tone arm uses a linear tracking system.
In this method, since the needle tip moves linearly on the record board, tracking error is eliminated and inside force is minimized.

The cartridge uses a dual magnet type.

It is equipped with a Computer Edit mechanism that enables editing and recording of records when combined with a SANSUI cassette deck.
With this mechanism, you can synchronize the start / stop timing of the player's performance with the start / stop timing of the recording on the cassette deck to prevent recording errors. In addition, you can edit and record freely by combining it with the automatic random program selection mechanism.
In actual operation, recording of the cassette deck is started by the command of the computer sensor when the needle tip goes down to the record board, and the cassette deck becomes recording standby after Rec Mute by the computer command when the recording is finished.
