  • 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.

    Features:

    • Variable microphone impedance
    • High quality mic preamp with polarity, pad and level control
    • Channel insert
    • Highpass filter
    • 1 balanced input, 1 mic input, 1 instrument input
    • Balanced outputs
    • Hand Crafted in the U.S.A.


    Integrating the 2BA-221 into your studio or live rig is easy given the comprehensive selection of input and output options provided. Summit Audio designed the connections of the 2BA-221 with creative options in mind.

    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.
