Commentary
This is a full auto player that pursues ease of use with remote control as well as quality as a single item.
The rotating system uses a 3-stage block consisting of a linear BSL motor, a magne-disk speed detector, and a quartz lock.
By removing the brush and slot from the DC motor, the linear BSL motor eliminates the mechanical torque change called cogging and achieves quiet and smooth rotation, while being more efficient and providing higher torque.
In the magnet-disk speed detection, a multi-gap head detects the mean value of the detection signal, which is magnetized at high density on the turntable, and detects minute changes in the rotational speed. Also, since the generated signal frequencies are relatively high, servo compensation is possible up to the higher frequencies of the flutter components.
It uses a quartz lock and utilizes the high oscillation accuracy of quartz to obtain stable rotational characteristics even with changes in ambient temperature and power supply voltage and frequency.
The tone arm is equipped with a low-mass straight arm to take advantage of the light needle pressure / high compliance cartridge.
It is equipped with an opto-electronic disc size selector that automatically selects a phonograph record and enables accurate tone arm lead-in.
The cabinet uses SBMC for superior internal loss and strength.
The cartridge is equipped with the XL-200 shell integrated MM type cartridge.
Equipped with a needle pressure setting guide and a disk centering guide that makes it easy to place a 30 cmLP board.
Centralized remote control by system remote controller sold separately is possible.
