Radial Engineering R8001508 HotShot ABi, XLR Input Selector

On-stage input switching
The HotShot ABi makes it easy to select between two balanced inputs on stage, with a single latching footswitch to toggle from one source to the other. This allows an artist to switch between two dynamic microphones during a performance, freeing up input channels on your mixer. The latching footswitch also opens the door for other useful applications, including using the ABi as a mute to turn off a microphone, select between two wireless receivers, or switch between two mono playback devices.

Using ABi to select between two microphones
On some stages, the performer may want to switch between two wired or wireless microphones that are positioned at different locations on stage. The ABi makes it easy to switch from one to the other with a single foot stomp.
Using the ABi to select between two sources
There are times when you want to quickly select between two mono audio sources. The ABi is perfect for this type of application. Simply connect the first device to input-A and the second to input-B. Hit the switch to select!

Using the ABi to mute a signal
On some stages, the performer may want to switch between two wired or wireless microphones that are positioned at different locations on stage. The ABi makes it easy to switch from one to the other with a single foot stomp.

• Quickly select between two balanced XLR sources
• Toggle or mute the source with a latching footswitch
• Selectable input pad to match input signal levels
• Completely passive operation, no power required

Can I use the HotShot ABi to switch phantom powered condenser microphones?
You could try, but due to the 48V powering of the mics, you could encounter a pop when switching, depending on the console’s grounding scheme. Always test at very low system volumes if you chose to use the ABi for these types of mics. Dynamic microphones do not require phantom power and therefore are safe and recommended.

Can I use the HotShot ABi to select between two direct boxes?
If the direct boxes are passive, this will work perfectly. If the direct boxes are active, you could encounter popping depending on how they are powered. 48V phantom power could pose a problem depending on the console. Always test at a low volume before switching phantom powered sources.

Can I use the HotShot ABi with two electric guitars?
You could, but the BigShot ABY is better suited for this as high-impedance guitar signals work best with hi-impedance coaxial cables and connectors.

Why are there no LED indicators on the ABi?
The HotShot ABi is a passive device. This means that it does not require any power whatsoever to make it work. We can do away with costly batteries, space hungry power supplies and phantom power which can introduce noise. The downside is that we do not have any power to light up LEDs.

Can I use the HotShot ABi to switch from two amplifiers into one speaker?
No. This would not be safe.
