Summit Audio 2BA-221

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.
