redeye 3D phantom
active buffered instrument input
This is the high impedance instrument input on the front
of the Redeye 3D. You must have the Redeye 3Ds output male
XLR on the rear of the unit plugged into a microphone preampli-
fier, and have the phantom power on the microphone preampli-
fier turned on in order to use this input. If the Redeye is properly
hooked up to the pre and the phantom is on, the red led will be lit.
The maximum level that you can feed into this input is ap-
proxi16dB before clipping (that's a lot for an instrument in).
The input Impedance is approximately 1 Meg ohm. We experimented
with a much higher input impedance which might of helped piezo pick
up users (piezo users see DIY section if you want to know how to mod)
but for standard guitars using passive pick ups like a Telecaster or a
Les Paul the 1 meg ohm sounded like plugging directly into the amp,
which when re-amping, is essential. We did not use a continuously
variable impedance dull control. In our experience these get acciden-
tally abused more than used and typically ended in the same position
all the time.
redeye 3D phantom
un-buffered instrument input
This is the passive un-buffered instrument input on the rear of
the Redeye 3D. This input requires no phantom power and the red led
need not be on for the Redye 3D to function in this passive mode.
If you are looking for the same sound as the original Redeye this would
be the input to use. It sends ypur instrument signal directly to the pri-
mary of the transformer.
This input is best for active instruments, keyboards, synths,
guitars with pre-amps built in, anything with lots of gain and not sensi-
tive to loading. The load presented by the Redeye or Redeye 3D for
these type instruments is very high at approximately 30k ohm, but not
high enough for passive devices which are much more sensitive to load-
ing.
redeye 3D phantom
line level female xlr in
This is the input of the re-amp section of the Redeye 3D Phantom,
what needs to be fed in here is a line level (+4dB) lo impedance balanced
signal from the output of a DAW, a tape machine or send off a console. The
input impedance on this input is approximately 9k ohm, or 4k ohm if the re-
amp overdrive is selected. I should note some other re-amping devices have a
600 ohm input impedance which can be tough to drive, and certainly cannot
be daisy chained like you can by using the expansion in and out jacks of the
Redeye 3D (see the next topic).
After the signal enters the Redeye 3D, the signal will be reduced
by approximately 15dB and converted to a hi impedance unbalanced (guitar
signal) and be available at the front panel instrument/re-amp level out jack to
feed an amp or pedal.
redeye 3D phantom
expansion in and expansion out
These are simply parallel (1/4" TRS) jacks with the line level fe-
male XLR in. They allow you to plug in unbalanced lo impedance signals
from the output of a DAW, a tape machine or send off a console, using a TS
(tip sleeve) plug, or from a balanced TRS plug if you don't have an XLR.
The expansion in and outs allow you to easily daisy chain multiple Re-
deye 3Ds so you can feed multiple guitar amps or pedals. I should note here you
can plug in the expansion in jack on the Redeye 3D from our other products, the
PCP or the Multi Z PIP expansion out jacks, but here please use a TRS balanced
cable. This creates another output of these devices which can be located far from
the source. So lets say you are feeding three amp heads in the control room with
the PCP use this method to feed a combo amp in the live room.
You can use your imagination and for example utilizing one micro-
phone preamplifier fed from the Redeye 3D mic level out XLR and back in the
line level female XLR in, create a guitar splitter which has as many outputs as
Redeye 3Ds. If you have four Redeye 3Ds rack mounted, in a pinch you can eas-
ily create a truly excellent transformer isolated guitar splitter! You can do a lot
more than that, but I will let you wrap your brain around it and figure out all the
possibilities..
