Adapts Low Impedance Mics
T50K
OVERVIEW
The T50K is a professional impedance matching transformer that allows a low
impedance microphone (100 - 600 Ohms) to connect to a high impedance input
(10 k - 50 k Ohms).
A typical application for the T50K would be to plug a low impedance microphone
directly into the high impedance input of a guitar amplifier for either vocals or
harmonica (see photo below).
In this case, one would plug the XLR-male connector of the microphone cable
directly into the XLR-female connector of the T50K. The 1/4” jack of the T50K will plug
into the guitar amp.
The T50K may be used with long microphone cable helping to prevent loss of signal,
loss of frequency response, and extraneous hum or noise.
