Applications
Using the 2BA-221 as an Instrument Preamp
The 2BA-221 makes a great instrument preamp for guitars,
basses, keyboards or whatever. In addition to the +4 Main
Balanced Output, the Stacking Output and the -10 Main
Output can be used to send the signal to the board, your
amp or a headphone monitor amp.
Turn up the Tube Output control for more tube sound, use
the Solid State input gain for a cleaner sound. To distort the
2BA-221, turn the Tube Output up to 2-3 o’clock and adjust
the solid state Hi-Z input gain to get a good level. Adjust the
solid state and tube output controls to get the desired
amount of distortion. Use the –10dB balanced output if the
XLR output has too much gain.
