I don't know the Allen & Heath mixers typically have balanced outputs instead of normal unbalanced jacks. I ran into the same issue when I tried to connect an Eq into the effects loop on my Yamaha mixer. The tip is signal+, the ring is signal- and the sleeve is ground.
Found this document (http://www.jensen-transformers.com/an/an003.pdf) that I haven't actually read myself yet, but I think it might explain everything in detail. |

| excellent thanks for that, so i think the key would be 2 use different connections. How did you get over your Eq problem in the end |

I didn't actually resolve the problem.
I got a practically unused 31 band Eq here.  |

Howdy... ...i would of thought that mixer aux sends and returns were more for rack gear than pedals,i know that even on the effects loops in some processors the manufacturers tell you in the manuals that there only there to connect up other rack gear(i.e my pod xt pro's stereo loop,they tell you to put pedals in the front end like an amp) something to do with an different level of signal between pedals and rack gear,some marshalls with effects loops have a +4/-10 db switch to let you go either way even if you make up the proper leads you might find the audio quality to be not as good as with a dedicated outboard delay like a alesis,lexicon etc..... |

You're right Franz, mixers work better with line-level outboard FX but inserts aren't usually balanced.
Oh, EXCELLENT link Bossarea! tks  |

Bossarea and all, if you have a device with a mono input and want to drive it from a TRS output on another device, just use a normal unbalanced mono lead instead of the TRS cable and it will work fine. All that will happen is the hum rejection from a balanced connection won't be available. Keep the cable runs short and power the gear all from the same socket and you should be fine with hum anyway.

| That's what I tried but I got no response from the effect unit. |

| Am i right in assuming a TRS jack and a stereo jack are the same....? i know the guy from lehle switchers says if your using his switchers in stereo like the D Loop from a mono source...(ie a mono pedal on the input in before the looper) and some sort of stereo effect in the loop he says ALL the jacks have to be stereo for the stereo effect to work so he recomends wiring a stereo jack in mono on one end of the patch cable otherwise the switcher just recognizes the mono signal..so if you wire a TRS for mono one end with the mono jack going into the DD-3 would that work...i think the extra ring on the TRS jack triggers something in the input of the mixer on am i way off the mark here....??...... hope i'm not muddying the water too much..... |

They're both 3-conductor jacks & so are the same. But be careful because if we're talking about FX sends on a mixer, they are usally switched jacks & support "jack-normalling" which ties the Left & Right jacks together for monophonic outboard effects.
Stereo is 2 channels or distinct signals over the 3-conductor with a common ground.
An "insert" on a mixer actually sends a signal to outboard gear on one conductor & receives the processed signal back on the other while sharing a ground & needs a special "wye" insert cable which looks like TRS on the mixer end & 2 TS ends for the effect input & output.
A balanced TRS is just like a microphone cable & inverts the phase on one conductor to counteract any interference. It requires a phase-matrix decoder ciruit on each end.
Regarding Lehle, it makes sense to combine the Tip & Ring together but isn't that what you're doing when you plug a TS into an effect unit's output jack? I'd need to give that some thought & am out of time right now. Suffice it to say, Lehle probably knows what he's talking about.  |
