OVERVIEW

The best of both worlds!

The variable-impedence Summit Audio 2BA-221 Tube Mic and Line Module is a microphone preamp that has individual controls to mix mic with Hi-Z or line inputs for variable vacuum tube output. You can mix them together through 12AX7A/ECC83 tube output or separately through individual solid state outputs. A stackable input design allows multiple 2BA-221s to be linked for 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.

FEATURES
  • Variable mic input impedance from 100 ohms to 10K ohms
  • Variable high-pass filter
  • Hi-Z instrument, line, and mic level inputs
  • Hi-Z input and mic input available simultaneously with separate gain controls
  • Separate solid state and tube outputs
  • Insert jack
  • Stackable with more 2BA-221s
  • 1/2 rack size
  • 3 year warranty
  • XLR and 1/4" I/O
  • 3 variable, independent gain stages

    Comments about Summit Audio 2BA-221 Tube Mic and Line Module:

    This is simply put an incredible preamp. I own a UA LA610 MKII and some vintage preamps (racked PM1000s etc). This blows most every pre out of the water. It has the fast, mid forward sound of a monolithic solidstate pre like Grace. But it also can get a big warm sound with the tube section.
    To be clear, it is a solid state preamp, only the summing/line driver output is tube.
    However, this is the ONLY hybrid ss/tube pre that actually works!
    The only complaints I have about it would be that the high pass filter and impedance pot do not apply to the instrument level input. It simply gets a gain knob and done. It would be such a huge monster of a pre if there was also such control of the hi z input. I'd also love to see a phase alignment facility to line up the direct and mic sources when summing the two to one track. This pre is awesome for being able to take a hi z input while simultaneously taking a mic input (at different levels!) Not being able to adjust teh relative phase means you are stuck with whatever phase anomalies exist due to the mic distance to source. This can sound great on slide, guitar and acoustic, but on bass guitar and cello it actually gets in the way on lower registers.

    Long story short, I am buying a 2nd one to have a stereo pair. Will probably run my mixes through them as well.

    excellent studio tool

    By Puffer Fish

    from Harrisburg, PA

    Comments about Summit Audio 2BA-221 Tube Mic and Line Module:

    First off--this thing is very solid. It screams quality when you get to check it out in person. The variety of routing inputs and outputs is quite unique and a real benefit when incorporating the 2BA-221 into the work flow. The preamp also has a very wide palette of sounds--from very clean to very warm and always sounding full and complimentary. The tube is very difficult to change because there is not a whit of wasted space inside the box. The impedance adjustment is very cool in that it is sweep-able, not just a few clicks. However, please note the impedance changes are not really effective with condenser microphones--you will see the biggest impact with dynamic and ribbon mics when adjusting the impedance. This preamp smokes the mic pres on my Presonus Firepod. It also sounds better than my Allen & Heath board. It compares favorably to any of the other gear I have and is simply an all-around great value. There are very few mic pres with this many features for any price.

    Summit 2BA-221 IS the summit

    Comments about Summit Audio 2BA-221 Tube Mic and Line Module:

    Had been using my 1-4 Mackie Onyx pres before this new addition. My "new channel strip" chain features the Summit 2BA with FMR Audio's RNC & RNLA into my Digi 002 rack. Bottom line is that I am now using the Summit strip for just about everything. The versatility of this unit is quite unique. Record your rig live AND direct...blend them together to your taste. Design-wise, the numerous connection possibilities make this unit extra special.

    Love it

    By Deadrunner-uhhW1

    Comments about Summit Audio 2BA-221 Tube Mic and Line Module:

    I finally got tired of bland sounding tracks. Got the 2BA-221 and at first didn't really notice much difference, I actually had to work at it. This thing makes you want to become a better singer/musician. With practice I was able to bring out my sound and place it perfectly in a warm full sounding track. It is amazing the difference it makes once I learned how to work with it. And how much more fun and easy recording can be with it. I love this thing. One last bit of advice, if you?re routing this through a cheap board, don't. I will kill the sound. I got rid of my board and connect straight to my m-audio 10/10. It makes a world of difference.

    Brings out the feeling

    By Deadrunner

    from Lake Forest Park, WA

    Comments about Summit Audio 2BA-221 Tube Mic and Line Module:

    This is a very solid unit. Originally I bought the Focusrite TrakMaster Pro it didn?t give any depth or really any thing beneficial to my music. I returned it the next week. After reading forums for the next month I found this one. I was skeptical but went for it. I am pleased with this unit. It's subtle but brings clarity and depth/warmth to my vocals. You can really bring out the vocals if you?re riding just under peek with the tube at with the impedance most of the way up. Depending on what mic you use. Has a lot of flexibility as well. I can go from blue grass twang to alt rock to industrial and with a little tweaking it lays the vocals in nicely with very little eq. So far this is the biggest improvement to my studio. It just works well and makes every thing else fall into place with a lot less effort. It also works well as an instrument pre too.

    Awesome little preamp!

    By vsimmons

    Comments about Summit Audio 2BA-221 Tube Mic and Line Module:

    I looked at everything out there, and since I record onto a pc, I wanted the warmth of tube, but also clean. This gives you the clean sound, but if you need the color, its there. That's why I chose it over the grace
