SDI Speaker Level Direct Interface


Item #: 03001350

The SDI allows the speaker output of an instrument amplifier to be interfaced to the mic input of a sound system. By using the amplifier speaker output, the distortion characteristics of the amplifier are preserved. The SDI attenuates the speaker level signal so that it can be interfaced to a mic input.
