Anyone had any experience using a 200 or 400 series lectro tx/rx at
the output of an acoustic guitar? (with a pickup obviously)

Wireless with instuments like that is not uncommon.
The PU output is likely to be higher than the mic level input of the
TX.

Check your levels and impedence match, you'll be fine.

Look at the Lectro tx manual, I think that one of the TA5 pins is for
that application, so you'd just have to build the right cable.

I seem to recall that for line input on the TA 5 you use pin 5 for
line level audio inputs.

I have done this many times. Electric and Accoustic. Takamine Santa
Fe, late 70's strat, mid 90's PRS) They are great for this as well as
almost everything else.

btw I didn't build any special cable just one of those 6$ silver xlr
to 1/4'' adapters.

Actually, we make several specific components for guitars, and our
systems are used by several top artists, including:

The Dixie Chicks (all backline, all acoustic instruments)
Carlos Santana (electric guitar)
Slash (electric guitar)
Alex Lifeson (acoustic guitars)
Paul Simon (acoustic guitars)
Etc.

The 400 Series is particularly suited to this application due to the
lack of audio compandor. The typical system consists of the LMA
transmitter and R400A receiver, but UM400A, SM Series or other 400-
series transmitters can be and have been used, and the Venue receiver
is also fairly popular for this application.

To interface between the guitar and the transmitter, we make the
following cables:

MI39A for medium and high-impedance guitar outputs (like passive
magnetic pickups typical of electric guitars, and also includes
Taylor's ES system, etc.) 90% or more of guitars would use this cable.

MI33P for low-impedance guitar outputs, like those on active electric
bass guitars using 18V systems.

The cables are available in either straight or right-angle versions.

Here's some info on our system:

The MI39A cable has a very high input impedance Field Effect
Transistor (FET) built into the cable with a matching circuit for the
servo transmitters in all our current line of transmitters. Most
guitar pickups, particularly the classic ones, don't develop their
"sound" unless they are looking into 1 Meg Ohm or more such as the
classic tube amp inputs.

I use Lectrosonics wireless for my performance rig, and I think it's
great stuff. My current setup is a McIntyre Acoustic Feather GF-30
pickup (passive) with a Lectro MI33ARA active preamp cable to a Lectro
REFUM (UM400, non-servo) Tx. It sounds great – clean, lush, tight. I
also run the same pickup with an MI39ARA preamp cable into a UM400a
(servo) Tx, with the same results. Another favorite is an LR Baggs
passive iBeam pickup into a GigPro belt-clip preamp and then a Lectro
MI33PRA (passive) cable from the GigPro to a UM400a Tx; the 33P sends
audio to Pin 5 (line-level input) of the TA5F. I run instruments with
active pickups like the Baggs iMix through the same MI33 cable
straight to the Tx, bypassing the GigPro. All these combinations have
produced excellent results for me. One final variation is when I want
to use a guitar with an active pickup and connect it to my REFUM Tx
which does not have a line-level input (Pin 5 is used for the mute
function); in this case I use a modified MI33PRA cable that sends
audio to Pin 3 (mic-level input) of the TA5F instead of Pin 5; the
level control in the REFUM Tx has enough attenuation range to handle
moderate-output active pickups like the iMix without a problem.

Hope this helps.

What is a 'Pickup', besides being an English/Dutch word (!?) for
'record player' (as in LP's) ? David C

Steel strings on the guitar vibrate above a magnet and many turn wire
arrangement that generates an electrical (audio) signal.

Quick look online didnt return any results on $$$$ on 139/133 cables,

The Lectro guitar cable part numbers are 'emm-eye-33' and 'emm-
eye-39'. Check out the Lectro website (www.lectrosonics.com) - lots of
info about the different cables and their use.
