Summit Audio 2BA-221 Microphone and Line Preamp Details

The Summit Audio 2BA-221 is a continuously variable impedance Microphone, line and, instrument preamp from Summit Audio. Featuring microphone level, line level, and Hi-Z instrument inputs, the 2BA-221 utilizes separate and individually controlled solid state inputs to mix the microphone input with the Hi-Z or line input into the variable vacuum tube stage. Mix the signals through the 12AX7A/ECC83 vacuum tube output or output them separately through multiple 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.

Best DI November 23, 2012
Reviewer: Calaverasgrande from Oakland, CA United States  
I don't consider this to be a Mic Pre. It is a DI that happens to be able to be used as a Mic Pre.
It makes any guitar or bass you plug in to it sound clearer, more defined, and just better. Great for re-amping in that regard. The variable high pass filter is excellent. You don't hear it except as an absence of frequencies.

What ever you plug in 2BA-221 sound AMAZING! August 5, 2010
Reviewer: Frank Durham from Doral, FL United States  
The 2BA-221, take my Newman U89i  
(natural sounding mic) to another level.
The U89i its a very difficult mic to get a the right sound of it.  But 2BA-221 puts his MODJO on my U89i:
First-it’s the variable impedance
(if you have a bright sound you move the impedance and get rid of these freq)
Second is the Solid State (clean and warm) ,
Third- it’s the Tube Sound (can be very subtle or very aggressive)
Fourth- it’s the ability to blend between Solid and ad some Tube sound.

Exceptional pre-amp for everything you throw at it March 28, 2008
Reviewer: Mark McFarlane from Saudi Arabia  
I've had a summit 2BA-221 for about a year and it is still my go-to preamp.  I'm happy with anything going through this and still choose the Summit over a Portico 5012 or SSL VHD (unless I want the SSL's distortion).  Very flexible, nice and clean if you want it or dial in a little warmth, every possible connection option you could imagine.  I  well engineered and great sounding preamp at an excellent price.
