MPN #2BA-221
Introducing the extraordinary 2BA-221 Mic and Line Module, featuring our remarkable continuously variable impedance microphone preamp
Full-plate voltage matters
The proper amount of voltage to a tube and solid-state circuit can make all the difference in the quality of the sound. The 2BA-221 is made with the highest quality full-voltage tube and solid-state signal paths and the best components available. The 2BA-221 even has a separate, dedicated power source for its 48V phantom power, and does not draw current away from the main circuits.
Let signal flow
Integrating the 2BA-221 into your studio or live rig is easy given the comprehensive selection of input and output options provided. We designed the connections of the 2BA-221 with creative options in mind.
Variable tube output control
Another really cool feature is its variable tube output control, which provides access to a huge variety of tones, from clean solid state to rich harmonics and all sorts of variations in between. What a benefit to have one preamp and still have the advantages of many different sounds! The 2BA-221's single 12AX7A Tube provides rich, warm tone and is easy to find and replace.
Really well built
The Summit Audio design philosophy considers the entire package when it comes to crafting gear. We pay special attention to the details of construction and have included many refinements over the years so units are durable enough to handle the rigors of the road. That is one of the reasons why you will find Summit gear on tour with many of today's top touring acts around the world.
More sounds from a single microphone
A primary design goal of the 2BA 221 was to provide an extreme amount of fine-tuning. One of the ways we achieve this is to allow you to variably adjust the mic input impedance. This opens up a wide variety of possible tones from a single microphone, turning a small mic locker into a much larger one by letting you tweak the way each of your microphones sound!
Hand-crafted in the USA
Each piece of Summit gear is meticulously crafted by hand in our shop using only the best quality components and attention to detail. Quality components and engineering know-how are the critical element to the sound and longevity of audio gear.
