Whirlwind Combiner
Item: WWCOMBINER
This versatile box allows you to use fewer input channels by combining two mic line into one. The Combiner is built with Whirlwind's premium TRSP-2 transformer for optimum durability.
Connections are two female XLRs in, one male XLR out.
Use the polarity reverse switch (which flips the polarity of input #2) to combine two mics - one with polarity reversed - to remove background noise and feedback or combine and correct polarity when using a pair of mics above and below a drum or in front and rear of an open backed guitar amp.
