    Q and A

    Q,Cartridge does not light up.

    A,Please use the troubleshooting document↓


    Q,Do you need this special EQ?

    A,Our optical cartridge requires the designated EQ.
    The reason is
    (1)This EQ provides electric power to the optical elements in the cartridge
    (2)Optical Cartridge Equalizing differs from those of MM/MC due to the
    amplitude proportional detection method.


    Q,Can you replace needle/Stylus?

    A,We will replace needle/Stylus upon your order and pre-payment
    please send us your cartridge for the replacement of needle/Stylus.


    Q, Is your optical cartridge non-contact reading of a record?

    A No. optical cartridge uses a needle/Stylus as the same as MM/MC cartridges.


    Q,Does optical cartridge work with any tone-arms?

    A, Optical cartridge EQ applies electric power
    to the optical elements in the cartridge through Ground lines of Left and right
    channel. In seldom cases, you find Tone arm having a common ground for left and
    right channels. DS-W1 does not work in such tonearms. Tonearm has 4 lines
    (Red/White/Green/Blue) to connect to a cartridge, and when Green/Blue ground
    lines are connected to a common ground, DS-W1 does not work. IF you are not
    sure, please refer to your tonearm manual or contact to your dealer /Tonearm
