of audio product development experience. Your TD-1 is a nely tuned
instrument intended for critical professional applications — with the added
benets of selectable vacuum tube DI amplier, all discrete FET solid
state DI amplier, variable input impedances, Speaker Soak
REAMP®, we feel it offers the world’s best sounding and most sonically
versatile DI + recording path. With the emergence of 24+ bit digital audio,
recording engineers are faced with a new requirement for undistorted
dynamic range. Twin Direct meets this challenge exceptionally well.

SAFETY PRECAUTIONS
For your safety and the safety of others, be sure to read and understand
all safety and operational instructions before attempting to use the TD-1.
WARNING: The TD-1 internal circuitry carries lethal voltages. Carefully
observe all warnings, precautions, and instructions on the TD-1 and as
described in the instructions supplied with the unit.
1. WATER, MOISTURE, AND SPILLAGE
Do not attempt to use the TD-1 in, near, or around water or in unusually
moist environments, such as near a sink or swimming pool. Prevent liquids
or any other materials or objects from spilling or falling into the TD-1 unit.
2. HEAT AND VENTILATION
Be sure to allow adequate ventilation to TD-1 and avoid using or installing
unit in close proximity to heat sources, such as heaters, stoves, radiators,
power ampliers, spotlights, or other heat-producing appliances or equipment.
3. POWER SOURCES AND POWER CORD PROTECTION
The TD-1 Power Supply should be connected to a power source only of the
type described in the operating instructions or as marked on the Power Supply. Route the power cord so that it is not likely to be walked on or pinched
by having objects placed on it. Pay particular attention to plugs, receptacles,
and the point where the AC power cord exits the TD-1.
4. GROUNDING
For your safety, it is extremely important that the grounding pin of the 3-wire
power cable (included with unit) be inserted into a grounding type 3-pin
power outlet. If you are unable to insert the plug into an existing outlet,
contact an electrician to install a properly grounded 3-pin power outlet,
preferably that with OFI / CFI protection, if available.
5. DAMAGE REQUIRING SERVICE
This unit should be repaired or serviced by qualied personnel whenever:
· The AC power cord has been damaged, or
· Objects have fallen or liquid has spilled into any TD-1 unit, or
· The unit does not function properly or exhibits a marked change in performance, or
· The unit has been abused, dropped, or damaged, or
· The unit has been exposed to rain or moisture

6. SERVICING
Lethal voltages are found inside the TD-1 chassis. The user should not
attempt to repair or service this unit. All servicing and/or repairs should be
referred to Millennia.
seconds for the phantom power to fully “ramp down” before inserting or
removing a microphone. This is good advice for protecting your microphone investments, as well.
If, after reading all instructions, precautions, and warnings, you have remaining questions, please contact Millennia directly before attempting to
use your TD-1. Retain this owner’s manual as a record of your purchase to
aid positive identication in the event of loss.
Before connecting power to the TD-1, assure that the rear panel voltage
selection fuse block switch is set correctly. In the USA or Japan, TD-1
is shipped with the voltage selection block set to 100-120 VAC. If you
change the voltage selection block to 200-240 VAC usage, be sure to
change both fuses to the correct types. See “Rear Panel” instructions for
proper fuse requirements.
The TD-1 enclosure measures approximately 8.5” wide x 3.5” high x
13.5” deep and is designed for mounting (in pairs) into a standard 2U,
19” equipment rack. If the TD-1 is mounted in a road case or other rack
which is prone to strong vibration or shock, it is highly recommended that
the rear of the TD-1 be supported or otherwise reinforced to withstand
such conditions. TD-1 contains high voltage vacuum tube and discrete
transistors, many running in Class-A bias. As such, the TD-1 TWIN DIRECT runs quite warm and should be mounted for proper ventilation with
at least one rack screw space open above and below the unit.
TD-1 is designed on a common ground topology. For high quality operation, and for your own safety and the safety of others, do not defeat the
power cord earth grounding pin. If required, earth ground can be lifted
safely via built-in switching, described later.
TD-1 FRONT-END PROTECTION: Millennia Music & Media Systems
enjoys a reputation for what many top engineers and producers call the
world’s most musically accurate and dynamically uniform microphone
preamplier — the HV-3. But this thoroughbred design is not achieved
without certain operating criteria. Back-to-back Zener diodes protect the
super-matched discrete bipolar input transistors against high transient
energy spikes common when inserting and extracting XLR connectors.
To maintain top performance and protect the TD-1’s sensitive HV-3 frontend, it is advised that you do not insert or extract XLR connectors with
power on. Get in the habit of disabling AC power and waiting about ten
DESIGN
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 transis-
tor (J-FET) ampliers. 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. Numerous functions and routing paths are available, as noted by name:
1.) HV-3 discrete hybrid solid state microphone preamplier
2.) STT-1 ORIGIN vacuum tube DI Input with selectable impedances
3.) Class-A biased discrete J-FET DI input with selectable impedances
4.) NSEQ-2 dual band fully parametric equalizer, 20 Hz - 25 kHz
5.) Patented REAMP® dual guitar simulation outputs (Strat & Les Paul)
6.) Numerous Ground-Lift and Ground-Isolation switches and jumpers
7.) SPEAKER SOAK
8.) Audiophile-grade headphone output with level adjustment
9.) Class-A biased discrete solid-state FET output stage
10.) High performance DIT-01 output transformer, 3 Hz - 300 kHz
