INSTRUMENT DI DIRECT OUTPUT “DIRECT OUT”
Conventional ¼” phone jack providing unbalanced output directly (“mult-
ed”) from DI input — before vacuum tube or discrete transistor impedance
buffers. This output is taken directly from the ¼” DI input jack. Direct Out-
put can be used simultaneously with all other outputs. Ring and Sleeve
are ground. With a positive input polarity, Tip is positive-going output po-
larity. This passive Direct Output can be also jumper selected with active
buffering from DI input. (See Jumper Map and Signal Flow Diagram later
in manual.) IMPORTANT: Using the Direct Output (buffered or unbuf-
fered) will impact DI input impedance. Unless you have a specific appli-
cation for the direct output, it is best to leave this output unconnected.
REAMP
®
OUTPUTS “REAMP I” & “REAMP II”
Conventional 1/4” female phone connectors (2 ea) providing passive-
guitar-pickup emulation via the patented REAMP technology (U.S. Pat
no. 6,005,950). Tip is signal positive polarity, Ring and Sleeve are gal-
vanically isolated ground. Millennia helped develop the original REAMP
concept, and now refines REAMP-ing technology to more effectively
emulate the output characteristics of Stratocaster
®
style single-coil pickups (REAMP Type I) and Les Paul
®
style dual-coil
“hum bucking” pickups (REAMP Type II). Both REAMP outputs can be
used simultaneously along with all other TWIN DIRECT outputs.
“Active sources” such as Tape Machine, DAW, and Hard Disk Recorder
provide an output impedance roughly 100 times lower than found on
passive electric guitar pickups. Driving a guitar amplifier from such ac-
tive sources will often result in a signal that sounds too “clean.” TWIN
DIRECT’s patented REAMP guitar simulation magnetics provide both
level and impedance matching characteristics which mimic traditional
electric guitar pickups, thus tricking the guitar amplifier to sound like a
live guitarist is playing. Use REAMP outputs to “re-amplify” a guitarist’s
performance at a later date, allowing unlimited time for experimentation
with different guitar amplifiers and miking techniques long after the guitar-
ist has gone home.
REAMP outputs are driven from specially wound shielded magnet-
ics designed to closely emulate the output characteristic of each guitar
pickup. TD-1 outputs can also be special-ordered with dual Les Paul
or dual Strat emulation transformers. As of this writing, other emula-
tion transformers (Jazz Bass, Precision Bass, etc..) are in development,
though REAMP Type II should perform adequately with most bass guitar
program.
Use this transformer-isolated output when (1) you require a microphone-
level signal or simply desire the coloration effect offered by certain
outboard mic preamps, (2) your application requires 100% galvanic isola-
tion, or (3) as a last resort if the Line Output (above) level is too hot, or if
your destination cannot handle line-level program. Output XLR connector
contacts are Neutrik gold plated. It is suggested that XLR cable connec-
tors used with the TD-1 employ identical plating.
TRANSFORMER OUTPUT GROUND LIFT Toggle Switch
A toggle switch which, when in the up position, lifts internal ground from
the Transformer-Coupled Output (above). When switch is in down posi-
tion, Transformer Output XLR Pin 1 sources internal analog ground.
MAIN OUTPUT #1 “BAL LINE OUTS”
Conventional three pin male XLR and 1/4” stereo phone connectors
wired in parallel, providing differentially balanced active line level out-
put. Can be used simultaneously with all other outputs. Pin 1 (sleeve) is
ground. Pin 2 (tip) is positive polarity. Pin 3 (ring) is negative polarity. See
Jumper Map for instructions on changing configuration for Pin 3 positive
polarity. This balanced line level output is capable of driving 600 ohm
loads and long, high capacitance cables with a maximum output level
of +32 dBu. Outputs may be configured in an unbalanced pin 2 (tip) hot
configuration by either grounding pin 3 (ring), or taking pin 2 directly as
an unbalanced signal while floating (not connecting) pin 3 (ring). In the
latter configuration, output is 6 dB lower than the former configuration.
XLR connector contacts are Neutrik gold plated. It is suggested that XLR
cable connectors used with the TD-1 employ identical plating.
MAIN OUTPUT #2 “UNBAL LINE OUTS”
Conventional three pin male XLR and 1/4” mono phone connectors wired
in parallel, providing unbalanced active line level outputs. Can be used
simultaneously with all other outputs. Pin 1 (sleeve) is ground. Pin 2 (tip)
is positive polarity. Pin 3 (ring) is ground. These unbalanced line level
outputs are capable of driving 600 ohm loads and long, high capacitance
cables with a maximum output level of +26 dBu. Outputs are 100%
discrete solid state (total of seven Field Effect Transistors) and are fully
Class-A biased. These outputs will usually drive balanced / differential
destinations with no interface concerns. In the rare instance where a
balanced destination exhibits difficulty with an unbalanced source, use
the balanced XLR or ¼” line output (above). XLR connector contacts are
Neutrik gold plated. It is suggested that XLR cable connectors used with
the TD-1 employ identical plating.
