Commentary
A belt drive type player equipped with a high sensitivity arm and CD-4 compatible cartridge.
The drive system employs a belt drive system using a 4-pole hysteresis synchronous motor and double-side polished polyurethane belt. Equipped with a bell and locking mechanism, the circuit switching button locks when the power is off to prevent the belt from twisting.
The shaft that supports the turntable is a combination of a 12 φ large stainless steel shaft with a precision finish and a gunmetal bearing to minimize aging.
The tone arm uses a high-sensitivity arm that takes advantage of the MA-77mkII design. The precision miniature bearing and unique ball pivot structure limit the horizontal and vertical sensitivity to less than 10 mg.
In addition, it is equipped with Micro's unique needle pressure-compatible variable inside four scan seller.
Uses a delay motion arm lifter to protect the record and needle tip.
The cartridge is equipped with V-3500/5 which is a VF type cartridge.
This cartridge can reproduce discrete 4 ch by the exchange needle V-3500/F for CD-4 sold separately.
The cabinet has a king rose finish design and comes with a large pocket that can store accessories.
Equipped with a low-capacity output cord and 5-pin terminal.
