Legendary Vari-Mu Compression<\/h1>\n

The Sta-Level has been one of the most sought\u00a0after Vari-Mu compressors:\u00a0for good reason!\u00a0With its stunning transformers and tube circuit,\u00a0most things sound better\u00a0just running through it. Hand-crafted by our small team in Chile, the Stam-Level is the most accurate sounding replica of\u00a0the\u00a0vintage Gates Sta-Level available on the market today. It works exceptionally well on vocals, guitars, bass or anywhere a more solid and beefy sound is needed during the recording process.<\/p>\n

Stam Audio has been building tube compressors for over a decade, and we decided it was time to do justice to this legendary piece. We have gone all in, with UK-made Sowter transformers, a US-made Choke, NOS European tubes and a linear power supply that precisely replicates this unit\u2019s unique low end and THD: and unlike others, we have not fallen sonically short.<\/p>\n

To add even more value, we included the\u00a0much requested dry-wet mix blend control, a 3-position side-chain high pass filter, a drive knob,\u00a0with 1dB increments and a true bypass switch,\u00a0all\u00a0housed\u00a0in a beautiful three-U faceplate with rack ears and yes, we outsourced the elusive original VU meter as well. Without cutting any corners and\u00a0while also ensuring that\u00a0it sounds exactly like an\u00a0original 1950\u2019s unit,\u00a0we are confident that the Stam-Level\u00a0will be the last Sta-Level replica you will ever need.<\/p>\n

The Iron<\/strong><\/h2>\n

We outsourced these transformers to several manufacturers and ended up settling with two UK-made Sowter transformers that painstakingly recreated the timbre, ratios and FR of the original transformers. Though much more expensive than other offerings, Sowter transformers provide superior performance to any other offering. Thanks to their meticulous craftsmanship we can confidently say the Stam-Level recreates every drop of character of the original Sta-Level both in the top and low end and can be used indistinguishably with an original unit. It also comes with a UK-made high grade core toroidal transformer allowing both 115V and 230V operation.<\/p>\n

The Tubes<\/strong><\/h2>\n

Tubes played a big role in the original character. Each Stam-Level is packed with 8 tubes with an all tube power supply including two matched NOS 6BA6\u2019s, matched 6V6\u2019s, one 12AT7, one 0B2, one 5Y3GT and one 6AL5. These tubes coupled with Sowter Iron ensures that the Stam-Level delivers the same mojo and low end that the original Sta-Level was famous for and that\u2019s typically missing from modern \u201cclones\u201d<\/p>\n

Extra features<\/strong><\/h2>\n

The Stam-Level is an exact replica of the original schematic from the late 50\u2019s and includes the standard Input, Output, Recovery Time and single, double and triple mode but incorporates several new crucial features.<\/p>\n

    \n
  • A 3 position side-chain high pass filter (off, 60hz and 120hz)<\/li>\n
  • Blend control<\/li>\n
  • Drive knob in 1dB increments to saturate the input and output<\/li>\n
  • A true bypass switch<\/li>\n
  • An off position to bypass the side-chain<\/li>\n<\/ul>\n

    The Aesthetics <\/strong><\/h2>\n

    Last, but not least, are the looks. We went the extra mile to source the original 3U faceplate and screws in a beautiful finish including the famous rack ears that gave this comp it\u2019s unique look. We also outsourced the original VU meter and knobs.<\/p>\n

    Manufacturing<\/strong><\/h2>\n

    We made\u00a0no compromises in parts selection for this build, ensuring you\u00a0the best sounding Sta-Level replica money can buy. Every unit is handmade and calibrated in our workshop in Chile,\u00a0where they get a full health check and are burned\u00a0in\u00a0for 72 hours to ensure your compressor will last for decades.\u00a0Stam Audio Engineering products are about sound quality first and foremost. Every component of every unit is premium quality and carefully selected to ensure our units match or even surpass the quality of high-end boutique gear.<\/p>\n
