SGA1566 MkII adds major enhancements to the critically acclaimed SGA1566. SGA1566 MkII is loosely based on a single channel vintage tube preamplifier with added two-band active Baxandall EQ and stereo processing. To achieve the most authentic analog sound, the whole preamp circuit is simulated in real time using the high performance circuit simulator. The two-band Baxandall EQ can be positioned either before or after the preamp, or be completely taken out of the signal chain. Up to 8x oversampling can be used to eliminate aliasing. SGA1566 MkII offers two different filter types for use in oversampling.
