  • SW1; BUF634 Wideband mode ON/OFF with 200 ohm connection btwn 1-4 pin.

    SW2; Output impedance changing switch (aka A47), and will improve stability for unstable OPAMPs,
    also changes proportion of output currents from buffers and OPAMPs.(Highly recommended to set this ON)
    Output current proportion
    When ON, OPAMP : BUF on front : BUF on bottom = 1 : 1 : 1 (OPAMP works 1/3), can achieve less distortion, stability.
    When OFF, OPAMP : BUF on front : BUF on bottom = 1 : 5 : 5 (OPAMP works 1/11), can provide more driveability for low efficient headphones.
