Award Winning Low Budget Variable Impedance Tube Microphone Preamplifier
A spectacualr little value in a low-budget variable impedance tube mic preamp. Allowing for variable impedance control of microphone inputs allows this preamp to match perfectly with a wide variety of microphones ranging from condenser mics to ribbon mics and dynamic mics. And, not only does it allow for some tube saturation on the main output, but allows for a second clean output which bypasses the tubes. For all of these reasons, the 2BA-221 really is a good value, and probably the reason that EQ magazine just recognized it with their award for excellence.
Introducing the extraordinary 2BA-221 continuously variable impedance microphone preamp from Summit Audio. Featuring microphone level, line level, and Hi-Z instrument inputs, the 2BA-221 utilizes separate and individually controlled solid state input controls to mix the microphone input with the Hi-Z or line input into the variable vacuum tube output. Mix them together through the 12AX7A/ECC83 vacuum tube output or separately through individual solid state outputs. The 2BA-221 also features a stackable input design; multiple 2BA-221's can be linked together to form a modular mixing device with individual outs, inserts per channel, and a final vacuum tube gain stage. Its swept high pass filter, multiple simultaneous tube and solid state outputs, insert jack, and internal power supply makes the 2BA-221 a powerful tracking and mixing tool.
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.
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.
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.
