There's no need to flail your arms wildly 'round the stage just to get the guy's sound some attention. When you use a selectorxl swirl, you'll be able to hide your signal to a separate channel and just talk for the MEC sound. In reality, there are several great reasons to use a selectorxl a/b switch microphone. For example, you may want to add delay to a single vocal line. This is easy. Just set the selectorxl to momentary mode, add a delay effect to the B output, and press the switch just when you want the effect. It's that simple. You can also attach nothing to output B and just use it as a cough switch... A real show-saver if you use a headset. Just as you use it, you'll be happy you're looking for a whirlwind selectorxl. .whirlwind selectorxl microphone signal a/b switch features at a glance: 1-to-2 MIC splitter with independent mute each way totally silent switching for use with dynamic condenser microphones or each switch is configurable as either momentary or latching
