    Constant impedance type attenuator.

    The constant impedance method allows volume adjustment without loss of sound quality. The attenuation is a 2-dB step 11-step switching type that can attenuate up to a maximum of -20dB.
    The handling capacity is 50W when the attached dummy load is connected.

    It can be used for 4 Ω, 8 Ω or 16 Ω speakers.

    Operating frequency range 100 Hz to 30 kHz
    Distortion factor 0.11% (200 Hz, 100W, 16 Ω Load)
    Attenuation -20dB max, 2 dB step
    Handling capacity 50W (When Attached Dummy Load Is Connected)
    Compatible Speaker Unit 4 Ω, 8 Ω, 16 Ω
    External dimensions Diameter 92x Depth 107 mm
