Commentary
A belt drive player with a high mechanic design within a limited price.
To prevent poor contact between the head shell and tone arm, gold plating is applied to both terminals of the head shell side and tone arm side.
Direct reading scale allows for accurate needle pressure adjustment.
When the balance weight is turned and the horizontal balance is achieved, the adjustment is completed by simply turning the entire weight from the state where the dial ring is set to 0 to the appropriate needle pressure.
Equipped with an inside force canceler. The canceling amount can be adjusted simply by raising or lowering the weight according to the needle pressure.
The turntable is made of 30 cm aluminum alloy die-cast, and the balance (dynamic balance) during rotation is adjusted one by one to prevent harmful vibration and uneven rotation.
A 4-pole synchronous motor is used for the drive part.
In addition, the turntable shaft is subjected to precision processing by the centerless polishing method, and combined with molybdenum disulfide grease, it has excellent wow and flutter characteristics.
Connection code pin plugs are molded in the same way as high-end machines to prevent disconnection and poor contact.
Also included is a connection code to the ground (GND) of the amplifier.
Aluminum die-cast is used for the motor sub-plate to remove the motor rumbling sound and improve the SN ratio.
The belt uses a precision processed polyurethane belt of micron unit.
Built-in audio insulator to prevent howling.
Uses a special panel support structure.
The arm moves up and down with the lever at hand.
Uses a player case used by Oceania cheeks natural wood.
Dust cover is a fleece top type and can be put on and taken off.
Tehcnics 280C MM-type cartridge is used for the cartridge.
