Easily select between two balanced inputs on stage using the HotShot ABi's single latching footswitch to select between sources, allowing you to switch between two dynamic microphones during a performance, alleviating the need for using additional unnecessary channels on the mixer. The latching footswitch can also be used for a myriad of other useful applications, such as using the HotShot ABi as a switch to mute a microphone, alternate between wireless receivers, or switch between two mono playback devices. HotShot ABi Applications Using ABi to Select Between Two Microphones - In some scenarios, the performer may wish to switch between two microphones that are located in different places on stage - the ABi makes it simple to switch between them with a single foot stomp. Using the ABi to Select Between Two Sources - The ABi is perfect for quickly selecting between two mono audio sources - simply connect the first device to input-A, and the second to input-B. Just stomp the switch to select! Using the ABi to Mute a Signal -  By connecting a source to input A, and nothing to input B, you can use the HotShot ABi as a mute switch. By switching inputs, the non-connected input acts as the mute circuit.
