Commentary
A record player with higher C/P by changing parts of the cabinet and motor from the GT-1000.
The turntable uses a 30 mm thick die-cast aluminum turntable with a diameter of 360 mm and a weight of 3 kg. Inertial mass of 600kg/cm when combined with a 400g SBR mat.2For the first time.
In addition, a DC4-phase 8-pole coreless motor with a starting torque of 1.2 kg ・ cm is adopted for the motor, and stable rotation is enabled by the quartz PLL system.
The tone arm adopts a static balance S-shaped tone arm and realizes 7 mg of horizontal and vertical initial motion sensitivity by gimbal support system. In addition, it adopts an arm base made of zinc die-cast and a 27 mm φ extra-thick strut made of brass machined.
In addition, it is equipped with thread suspension type anti-skating mechanism and height adjustment mechanism.
Equipped with an aluminum die-cast head shell to prevent harmful vibration by thickening the connector part.
The cabinet is 88 mm thick (including bottom plate) with 18 mm thick high-density particleboards firmly pulled up.
In addition, a combined spring and rubber insulator is used for the leg part.
3.5 mm thick dust cover has been adopted.
As a separately sold option, the tone arm YSA-1 adopted in the GT-2000X and the straight arm YSA-2 produced in limited quantity can be equipped.
Non-contact optical auto lifter YAL-1 can be used.
Anchor block YAB-1 can be used.
The YAB-1 is a set of two dumbbell weights connected by a horizontal bar. The weight of each set is 32 kg, and the weight of GT-2000 can be increased to 60 kg.
In addition, it comes with a spring-rubber compound foot with height adjustment mechanism that can be used by players other than GT series players.
Disk stabilizer YDS-3 can be used.
The YDS-3 has a double structure consisting of a brass ground metal part and an African paddock wood part. You can enjoy the change of sound by using both parts separately.
74 mm φ x34mm aluminum / brass composite disk stabilizer YDS-8 can be used.
Pinpoint block YPB-1 can be used.
YPB-1 is a brass machined pinpoint block that can support GT players, speakers and amplifiers with points.
Disk stabilizer YDS-1 can be used.
The YDS-1 is an electric pump type record adsorption system using a brass milling machine. In principle, it can exhibit the power equivalent to increasing the record weight to 4.5 kg.
