Product Description

Introducing the extraordinary new 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.

Customer Reviews

Versatile and good!
I have a pair of 2BA-221's, and they are the heart of my personal recording setup. I have only begun to explore the possibilities of this unit. The solid state mic preamp is detailed and clear. The tube gain sounds good if you want a little edge or if you want to get all warm and fuzzy. It has more inputs and outputs than a piece of Swiss cheese...all very useful. The impedance dial is fun to play with. You can dial in the proper impedance based on your mics specs, or just turn the knob until it sounds good. Add the hp filter, pad and phase inverter, and what more could you want from a preamp at this price? I have a Millennia TD-1 with an HV3 mic preamp, and I find the 2BA-221 more useful all around in getting the clear tracks I want without a lot of EQ. I would characterize the sound as being a little on the bright side and prefer neutral or darker sounding microphones through it. Ribbon mic lovers will be glad to know the designer endowed this little unit with a lot of gain. I haven't used the line in for an instrument DI, so I have no comment there, but I would bet you could get some killer acoustic or eletric guitar sounds.
