Summit Audio 2BA221 Microphone And Line Module

The 2BA-221 from Summit Audio is a microphone/line preamplifier that is professionally designed featuring continuously variable microphone impedance. The preamp comes utilizing the separate and individually controlled solid state input controls for mixing a microphone input that comes along with a Hi-Z or line input into a variable vacuum tube output. With the use of both the variable impedance and variable solid state and tube stages are providing a high level of sonic control.

But this is only half the story. Along with the required I/O, the unit comes featuring an insert before the tube stage, a variable 20Hz to 200Hz high-pass filter, 20dB pad, 48V phantom and polarity reverse. The 2BA-221 also comes featuring a stackable input design allowing multiple 2BA-221's to be linked together to form a modular mixing device along with individual outs, inserts per channel and a final vacuum tube gain stage.

The unit's versatility is further extended with the use of the multiple outputs. By plugging in a 1/4" cable into the insert jack and with the use of the "stack output," the 2BA-221 is capable to provide a total of four high quality outputs from one source. For example, the microphone source is designed capable to be sent to a recorder from the +4dB balanced tube out, that comes along with a backup to another track from the -10dB tube output to avoid any "overs" and send the solid state '"stack" output to a compressor and then to yet another track.

On the input side one could plug an acoustic electric guitar into the Hi-Z input and place a microphone in front of it and use the separate line and microphone input controls for mixing the signals into the one, perfect blend.

All of this functionality is packed into a very compact 1U half rack chassis that comes along with an internal power supply. The tube output is utilizing a high voltage plate, not the starved plate compromises of lower cost units, but is still delivered at an exceeding favorable price considering the myriad features provided, along with the traditional sonic quality of a Summit Audio product.
