The MA-202 Instrument and Microphone Adapter from Ampridge is a cable and adapter set that allows for connecting an electric instrument and a microphone into a single 1/4" input on an amplifier. Simply plug in the instrument and balance the volume using the controls on the guitar, bass or keyboard.
A specialized circuit combines the signals without the problems typically encountered when using a generic Y-cable by keeping the interaction between the instrument and microphone at an unnoticeable minimum. The included MT-21 microphone adapter is used to connect the XLR output from a normal low-impedance microphone into one of the GA-101 adapter jacks.
