Cable question (XLR - TRS)

[thebo]

I'm trying to hook up my compressor, which has XLR outputs only, to a
Kurzweil Rumour, which accepts only TS or TRS connectors. I've tried
using an XLR to TS cable with no luck, as the sound coming into the
Rumour sounds trebly and thin, with very little bass response.

If I were to use an XLR - TRS balanced cable, would I be able to
connect these two units correctly and get the full signal to the
Rumour? Any help is greatly appreciated.

Thanks,
Greg

assuming the cable is wired correctly for the application then it
sounds like a impeadence mismatch to me
hopefully someone with a better ability to explain things will chime in

Since you're listening to the output of the Rumour, you know for sure that it's
the input that is sounding thin & trebly? IOW, you're checking with the effects
bypassed, right?

If the Rumour truly has balanced TRS inputs & the XLR - TRS cable is wired
properly, then yes, that will fix the problem. I suspect, though, that you can
equally well use an unbalanced TS cable. It sounds like your XLR - TS cable is
wired pin 3 hot, or else your compressor is pin 3 hot or not in fact truly
balanced.

Or it's a transformer and pin 2 or 3 is floating.

What kind of compressor is it? Does it have a transformer-balanced output
or not?

Maybe. What is it, and how is your cable wired?

Thanks for the replies, everybody. The compressor I'm using is a
Chandler LTD-2, which have XLR in/outs only. Not sure if there's a
transformer there. The XLR-TS cable seems to the problem, since I've
gone out from the LTD-2 with XLRs to a Speck ASC equalizer, which
accepts XLR or 1/4", and has the same for outputs. So if I go out the
compressor via XLR into the Speck, then out from the Speck with TRS to
the Rumour, the sound is fine.

I was hoping to be able to bypass the Speck and go from the Chandler
to the Rumour using the right cable, but perhaps there is an impedance
mismatch which the Speck somehow corrects.

Maybe I'll just keep the Speck in the chain and bypass when not using
the eq.

BTW, in case you haven't heard it, the Chandler compressor rocks.
That's why it's permanently connected in my signal chain!

Strange, thought I posted a response this afternoon, but it didn't
show up. Anyway, the compressor is a Chandler LTD-2, not sure if
there's a transformer on the output. I don't know how the XLR-TS
cable I tried is wired.

Right now, I'm using a Speck ASC equalizer in the signal chain, which
accepts the XLR from the Chandler and offers a TRS output that I
connect to the Rumour. I was hoping to take out the Speck, but maybe
I'll just keep it in and bypass when I don't need eq.

Thanks all.

Though not, it seems, when connected to your Kurzweil Rumour .

geoff

PS hope somebody acquainted with either/both devices can help you.....

Since there's more than one way that it could be wired, this will
prevent anyone from giving you a difinitive answer.

Figure it out, and re-post your question with all the details and
you'll get a valid answer, or the answer may become apparent to you
once you figure out what you have.

There's no reason why you should have to use your equalizer to
interconnect two boxes.
