Product Description

Twin Topology Class A recording channel

The TD-1 now includes a gig bag.


The TD-1 TWIN DIRECT is a collection of core Millennia products designed into a sophisticated recording channel + direct box. We believe TD-1 is the world’s most versatile and absolutely best sounding DI (direct injection) box. TD-1 offers numerous signal path topologies (vacuum tube, discrete transistors, monolithics, three different audio transformers, speaker soak, REAMPs, etc.) all sonically optimized to their respective strengths. TD-1 offers Twin Topology DI input stages which can be switched to employ high voltage vacuum tube (12AT7) -or- 100% discrete transistor (J-FET) amplifiers. The user may also select low, medium, or high input impedance on both input topologies, making TWIN DIRECT the most versatile DI available. The TD-1 also offers two bands of Millennia’s acclaimed NSEQ-2 fully parametric equalization, used by top mastering facilities around the globe, fully sweepable from 20 Hz to 25 kHz. The NSEQ-2 bands are provided for high-resolution audio sculpting of instruments such as guitar, bass and keyboard, or artistic and corrective work — adding “air” and “punch,” removing “mud,” and so forth — all with the natural, artifact-free audio qualities NSEQ is known for.


Multiple Paths, One Goal: Total Sonic Realism

  • Four distinct inputs can be optimized for any source
  • Instruments – Twin Topology® DI channel; dual-triode 12AT7 vacuum tube or discrete FET solid state
