    Description

    This is a low noise JFET input, all discrete transistor tone control stereo board. The
    input is re
    sponsible by low noise J-FET 2SK246 which a
    cts as a buffer to
    provide low
    impedance output to
    the tone cont
    rol circuit
    network. Th
    is is followed by a low noise NPN transistor to provide the appropriate gain. The transistor is ope
    r
    ating at 100% feedback mode
    . This
    is thus
    a unity gain
    circuit
    and dedicated for tone control purpose.
    The board cont
    ains two
    audio channel, and each channel's tone control can be individually adjusted for maximum flexibility.
    The board is a slim design so it can be
    retrofitted to your existing project or put into a handsome housing.
    Control range:
    low side : 30Hz -- -22dB to +19dB ,
    high side :
    20KHz -- -19db to +19.5dB.
    Small signal distortion < 0.1% ; 2V distortion @12.5khz < 0.85%.
    Input impedance : 40K ohm.
    Output impedance : 180 ohm
    Gain : uni
    ty
    PCB Dimension : 55mm x 160mm.
    Supply voltage : +24V dc.
