Summit Audio 2BA-221 Mic and Line Preamplifier - Manual (Page 2)

Model 2BA-221 Microphone Preamplifier 2
Introduction
Introducing the 2BA-221 continuously variable impedance
microphone preamp from Summit Audio. Featuring micro-
phone 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.
