1.0 INTRODUCTION
The SA-16 is a modern, state-of-the art, active summing amplifier capable of providing
the character from two legendary flavors of the 70’s; accomplished by switching
between two fully discrete, independent output stages.
Every audio signal goes through a THAT CORP 1240 chip as a line receiver; from there
the signal goes into the summing circuit, centered around a 134 Op-Amp which is
recognized as the best integrated Op-Amp on the market. Finally, the signal reaches the
output stage; where you can select between three different flavors: a clean & wide solid
state choice (as found on the Oxford consoles), an “A” styled 2520 Op-Amp based
output section as found on vintage American consoles (in your face, punchy and tight)
and an “N” styled BA-440 output section (as found on the legendary 33609) giving you
instant “British” vibe & attitude!
The SA-16 features three balanced stereo insert points; allowing you to add your favorite
external units (such as compressors, limiters, and equalizers). A fully stepped output
level control and three selectable output stages (Standard, British and American MODs)
round-out the features of the SA-16!
