Moog Music Forum

Hi,

I was wondering if the audio input/output jacks in the moogerfoogers are balanced or unbalanced (or both).

The manual (from the Murf for example) says :
"AUDIO IN 1⁄4” phone jack – accepts any instrument-level or linelevel
signal from –16 dBm to +4 dBm."
and
"LEFT/MONO OUT 1⁄4” phone jack - -4 dBm nominal maximum
output level; +8dBm absolute maximum output level. Output
impedance is 1,000 ohms."

1) when connecting an instrument (like synth) I guess I only have one option and that's connecting an unbalanced cable from the synth to the AUDIO IN, but if i'm connecting the AUDIO OUT to my DELTA 66 (which supports balanced) should i go balanced from the Murf AUDIO OUT to the DELTA 66 AUDIO IN?

2) or if for example I'm using the MURF on an already recorded channel and I'm connecting the DELTA 66 AUDIO OUT to the MURF AUDIO IN should I use a balanced cable?

Thanks for your help,

Itai.

AFAIK the 'foogers run unbalanced. Sometimes you can find out by pushing a cable in slowly. If it has one click, it's unbalanced (TS). If it has two, it's balanced (TRS). Definately not foolproof, but might give you an idea.

I think they say "any instrument/line level" because you can use any level signal and attenuate with the Drive knob. So, if you were using a line level (from Delta) you would turn the Drive knob counter-clockwise until the level LED is orange most of the time (or red if you want to induce some distortion/overdrive!).

Balanced connctions are for professionnal applications (long cable, shield...)

I don't know any FX pedal with balanced audio.
There's no link between connection type and audio quality.


CONTROL Inputs use TRS jacks (signal/+5.7V/ground) but are not balanced (of course)

Some high end rack gear uses balanced connections.

Somebody kick this idiot!

Most certainly a link between connection type and audio quality.

First off, unbalanced is gonna be at least 6dB quieter.

If you need to go more than 10 feet or so you're gonna want a balanced signal for that.



The outputs on a Mayer VoodooVibe are balanced and buffered.
