The 2BA-221 is a continuously variable impedance microphone preamp that features a microphone level, line level, and Hi-Z instrument inputs. This half-rack sized unit 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-221also features a stackable input design; multiple 2BA-221'scan 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.
