How can I multi-track with a single 2BA-221 Mic/Line Module?
One of the many features of the 2BA-221 is the multitude of inputs and outputs. Not only does this make it easy to install it into your studio, it also gives you tons of flexibility when it comes to tracking. Let’s start with the outputs. The 2BA-221 has a total of 4 outputs. The main output is of course the +4dB XLR Tube output. Right next to that is the -10dB 1/4″ TRS Tube output. To the left of the tube outputs is something called the “stacking” output; this is the solid state output also running at -10dB. This is important to note: the polarity on this output is inverted in relation to the other outputs. Where is the forth output? The INSERT jack can also function as an output by simply plugging in an unbalanced (TS) 1/4″ jack. This is solid state output number 2. Now it’s time to multi-track a single source. Let’s say we’re tracking a vocal. Plug in your choice of microphone into the mic pre input. Set the solid state gain to a good level by watching the three segment LED meter, a
