Item Description
Listed 8 months ago
From a clean, smoke-free studio. In excellent condition.
Sent to Millennia in April 2025 for a checkup and to ensure the unit is up to original factory specifications. Comes with a brand-new carrying case that John La Grou sent back with it after giving it a clean sweep.
The unit was originally in a rack, and the factory rack ears are included. Ordered new feet and a new handle while Millennia had it, so it now has a desktop or a rack option.
Scuff on right side above power transformer retention screw is from the removal of a name tag sticker. The unit has not been rubbing against anything or damaged.
Intended on keeping it forever but I need to transition to a fast-and-light live recording setup, so sadly letting it go to fund other gear. Recently replaced tube (JJ ECC81).
From the original Sweetwater product description:
Audiophile Quality in a Portable Unit!
Millennia introduces the TD-1 Recording Channel. TD-1 is a compact yet sophisticated analog "channel strip" for microphones, electric guitars and basses, acoustic instrument transducers, keyboards, DAWs, and all MIDI systems. TD-1 "Twin Direct" includes Millennia's acclaimed HV-3 microphone preamplifier, making TD-1 an uncompromised front-end for virtually any audio recording application. Some have called TD-1 a Mini-Origin.
Tube or Solid-state
Audio engineers no longer need to chose between tube front-end or solid state front-end. TD-1's instrument input employs Twin Topology - Millennia's innovative merging of vacuum tube and solid state circuit topologies. TD-1 offers a high voltage 100% vacuum tube instrument amplifier -or- transparent 100% discrete F.E.T. solid state instrument amplifier in the same indestructable military-grade chassis. Both topologies can be switch selected and musically tuned via three selectable input impedances (470K/2M/10M). Up to 65dB of adjustable microphone and instrument gain is available via front-panel control.
Patented REAMP Outputs and Speaker Soak Technology
A simultaneous pair of patented REAMP outputs allow TD-1 to emulate both Les Paul and Strat pickups (Les Paul himself plays through a Millennia Origin). REAMP causes the guitar amplifier to think it's connected to a high impedance passive guitar pickup, instead of a very low impedance (and much too clean) active tape recorder or digital workstation output. Millennia's uncompromised DIT-01 mic-level DI output transformer (Frequency Response -3dB @ 3Hz & 300kHz) is also included. Recording directly from any guitar amplifier is now possible with Millennia's innovative Speaker Soak technology. Simply connect any parallel speaker output (300W max) and start recording the authentic character of your guitar amplifier output under true dynamic speaker loading. An audiophile-grade headphone output with separate level control is also provided for pre-auditioning.
Discrete Circutiry with Parametric EQ and Wide Variety of I/O
A fully sweepable NSEQ-style parametric equalizer (20Hz - 25kHz) provides an unlimited range of adjustable tonality. NSEQ is the same equalizer used by top mastering facilities around the globe. Ultra-transparent NSEQ bands are provided for high-resolution audio sculpting of instruments such as guitars, bass, and keyboards, or artistic and corrective work - adding "air" and "punch," removing "mud," and so forth ~ all with the smooth and artifact-free audio qualities for which NSEQ is well respected. Use as much or as little signal processing as you desire. TD-1's main signal path employs 100% discrete circuitry from input to output for critical sonic transparency and wide dynamic range. Switch in any number of additional processing features for enhanced utility and innovative functionality. Useful features such as polarity reversal (on all inputs), relay controlled -20dB auto-balanced PAD (on all inputs), three ground lift switches + isolations (power / input / output), logic-controlled switch mutes, and worldwide internal toroidal power supply (user selectable 100V - 240V) provide enhanced versatility. TD-1 has four available audio inputs including Line Input (XLR), HV-3 Mic Preamp Input (XLR), DI Instrument Input (1/4"), and Power Amplifier/Speaker Soak Input (1/4"). All inputs are followed by the NSEQ parametric equalizer. Numerous routing, output, and grounding options round out the TD-1, including nine simultaneous audio outputs and distribution points:
REAMP Stratocaster (filtered) Guitar Simulation (1/4" phone)
REAMP Les Paul (linear) Guitar Simulation (1/4" phone)
Balanced Line Level Output (XLR)
Unbalanced Line Level Output (XLR)
Balanced Mic Level Output (XLR transformer-coupled)
Balanced Line Level Output (1/4" phone)
