There’s nothing new about ABY boxes. They’re a very commonly used accessory and a staple part of many setups out there. But if they are so common, then (until we launched our passive Stereo ABY) why was it so difficult to find one in a stereo format that’s well built, noise-free AND affordable? This is a question we kept encountering as we use many stereo devices daily here at KMA, plus we know that a lot of users are just as mesmerised by the wide sonic worlds of stereo as we are. So, we made a killer stereo ABY switcher to use here at our workshop. In the process, we found it so useful that we decided to make the original STEREO ABY available to the world, too, in a pedal format. 

However, despite our passive boxes gracing thousands of rigs the world over, the Active STEREO ABY takes things a little further and is ideal for those who like to use the Y splitting or combining functions - at least with some signals that don’t always play nicely together, due to often differing impedances between connected devices. With KMA’s high-quality active buffer, the pedal can also help eliminate level mismatches or even signal loss if used with long cable runs.

Whether you’re looking to switch or combine a Stereo input signal between two separate destinations or switch or combine two separate Stereo input signals into a single stereo output without signal loss, the KMA Machines Active STEREO ABY pedal is a dependable little helper for your tonal quest - the fate of your Stereo signals is in your hands!  

KMA’s ABY Series has been created with a focus on durability, reliability, simplicity and hassle-free operation.

The Active ABY pedal features a fully active design along with our active silent CMOS switching. While that might be a hell of a wordy mouthful (or even sound scary to some), what it means practically is that the pedal is completely silent in operation. This has the added benefit of allowing for all sorts of hookups, helping to prevent signal loss. Being active can also minimise any potential level mismatch between hookups.

It can be electronically difficult to achieve this kind of switching without interference between the switching and signal paths, but by employing our own implementation of this switching technology, not only are the mechanical switching noises greatly reduced, but the risk of any pesky loud clicks and pops that has plagued so many boards and has haunted so many musicians, since the inception of ABY boxes when switching, is virtually eliminated.

The bear's eyes light up - how awesome is that!? Okay, besides just looking cool and fulfilling our childhood dreams of an army of robot bears with freaking lasers as eyes, the 3 distinct LEDs in the Active ABY actually serve a practical purpose; to quickly and easily show you what signal path you’ve selected at a glance. Red for A, Yellow for B and Blue in the centre for A&B. With the A&B>Y or Y>A&B switch, you can use the device in either direction, for sending to different sets of amps, synths or effects or for switching inputs/ instruments/ devices into your chain via the Y channel, for even more creative combining or splitting. The Phase switch allows for flipping the A Channel by 180°. This can prevent signal cancellation and tone issues that can happen in some setups when combining or splitting signals.

This pedalboard-friendly device seamlessly integrates with your existing setup. It's compact, rugged, lightweight, durable, affordable and can be powered via a standard 9V DC power supply, making it convenient for all walks of sonic life. What’s not to like? So, will you choose A or B? With the KMA Machines Active STEREO ABY pedal, all you have to do is choose your path and perform!
