18 Channel Summing Amp with built in British and American Mods

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!

American MOD.

Utilizing two SA-2520 Op-Amps and Two Custom-Wound, USA-Made 312 “A” styled Steel Transformers!

British MOD.

Featuring the output stage of a 33609 (incorporating Two BA-440 cards as found on the ‘metal knob’ revision) and Two Custom-Wound, EU-Made LO116 “N” styled output transformers!

When the Standard Output is selected, you will get an extremely clean, clear and wide output stage with high performance THAT CORP line drivers that have a high slew rate, low distortion and a wide output swing – a big, spacious sound akin to the Oxford-line of consoles.

When the American MOD is selected, the SA-16 will pass through an “A” styled output stage with two Fully Discrete 2520 Op-Amps and two 312-style steel output transformers giving your mixes a pleasant mid-range push and punchy aggression!

When the British MOD is selected, the SA-16 will pass through an “N” styled output stage with two Fully Discrete BA440 cards (as found in the output stage of the ‘metal knob’ 33609) coupled with two beefy LO116-styled custom output transformers; giving your mixes immense low end extension and a tone that is instantly recognizable!

To achieve the lowest possible electromagnetic noise specs, each SA-16 comes with a premium, custom-spec external power supply!

    No doubt this will be a great product – with many great summing boxes from different manufacturers this one adds the 3 top dog console sounds in one box – brilliant !!! . Stam Audio is known for top quality gear without breaking the bank … ‘-)
