Whirlwind IMCOML Line Level Combiner

Line Level Combiner - 2 In, 1 Out

This unit not only combines two line-level signals into one line level output, it also compensates for the 6dB of gain that occurs when two in-phase signals are combined. A handy ground-lift switch breaks the shield connection between the inputs.

Use the line level combiner when you want to create a mono mix from a stereo source but need to keep the original stereo signals isolated. It's great for feeding a DAT player or CD into a mono system or single channel on a board.

Connections are female XLRs in, male XLR out.

Features:

• Use fewer input channels by combining two mic lines into one.
• Use the polarity reverse switch 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.
• Connections are female XLRs in, male XLR out.
