This sophisticated device offers over 130 optimized signal topologies, providing an expansive sonic palette for producers, engineers, and musicians alike.

The STT-1 Origin features twin mic preamps, the M-2B vacuum tube and HV-3 discrete solid state, offering you the flexibility to choose between the musically rich warmth of vacuum tubes or the precision and clarity of solid-state technology. It also includes twin NSEQ-2 Mastering-Grade Parametric EQs, allowing you to shape your sound with either vacuum tube or discrete solid state.

This advanced channel strip is equipped with three Opto Compressor/Limiter paths, including TCL vacuum tube, discrete solid state, and passive, providing you with a range of dynamic control options.

Its input coupling can be done with or without the MIT-01 audio transformer, offering you the flexibility to add a "fat", euphonic coloration to aggressive sources like drums and electric bass.

Constructed with gold audio connectors, tube sockets, relays, and switches, this channel strip ensures optimal signal integrity. The durable black mirror-gloss anodized finish and mil spec 16 gauge cold-rolled steel chassis add to its robustness, while the ultra-clean toroid power supply housed in an internal sub-chassis ensures noise-free operation.
