    I think what you're saying is best practice would be to use the TS to TRS adaptor (the silver one in the same pic)?

     

    Yes.

    . We then have a further 6 balanced mono outs, some of which can be paired to provide additional stereo IEM feeds for those that want it (obviously not an option for the Xvive U4 users). That's definitely an additional worthwhile take-away from this chat! 

     

     

    indeed - that's what mine are (as I have balanced TRS outs on the X18)

    For normal mono outs, I have TRS to XLR adapters, and I do have a dual XLR mono to XLR stereo cable (or a few of them) that I could use, they usually are with the chapman stick that has a stereo out. 

     

    - edit - I note that this is now actually OTT, as I could go from the stereo ¼" jack to the ¼" jack on the IEMs - its just I have these cables anyway as I was using the MS-2 before hand, and that only had a 3.5mm jack

    I don't think your brain would notice ears being out of phase as that happens all the time with sounds arriving at one ear before the other. 

     

    It would be exactly the same as the sound coming entirely from one side, ie 90° to you, but somehow being as loud on the back side

    If it makes an "in principle" difference, I guess it would be best practice to be using the silver TS to TRS adapters as standard rather than the gold TRS to TRS adapters? 

     

    What is a TRS to TRS adapter? Why would you need to adapt that?

    Those plugging their 1/4" stereo jacks from their wireless IEMs (eg Swiff WX520) into a single balanced mono aux-out jack will just have to take what they get!

     

    if you plug a mono lead in, it would be fine, its only with a stereo lead. Thats one advantage of a balanced output, it would give you a fine mono output if you use a TS jack.

    I realised that I don't touch my G string (the one on my bass) while playing with either of my metal bands or while playing any of my favourite covers at home. Is this unusual?

     

    I don't think so. I am in a general cover band and a metal band. The metal band almost never go past the first 2 strings, the cover band does all of them. I guess metal just stays in the mud!

    Thanks Woody. But that's an additional point to amplification though? And would on the face of it apply to any IEM whether wired or wireless being fed into an aux-out?

     

    Absolutely not. If you connect to a TRS you have a balanced output, and a ground. The signal (a mono one) is amplified in some IEM amplifier, the ground maybe connected to the hardware ground, or isn't, it doesn't matter. that is the correct way. If you connect a mono source to a stereo output, you need to sum both stereo lines to that mono line. The way you are doing if you are putting a mono source into a stereo headphone, both sides are 180 degrees out of phase with each other.

    I see that the 6 aux-outs of the Beheringer XAir XR18 are all 3 pin XLR  - so no possibility of putting a normal headphone jack into those sockets, plus one headphone out?

     

    I have an X18, not an XR18, they are all TRS (and a headphone out). But they are aux line level out so it would have never occured to me to put them into a headphone! (and the normal aux I used was a TRS plug to an XLR socket.

     

    1 hour ago, Al Krow said:

    The aux out sockets on the CQ18 are balanced mono, and I remember you saying that most aux outs are similarly mono? Now the Xvive U4s we used are also mono - so I guess that deals with any phasing issues for those particular devices?

     

    Absolutely. In fact any 'normal'* IEM system would expect a balanced mono, the same as most other XLR use in gigging

    But given what you're saying, that then leaves the question as to why we or anyone gets a clear feed into stereo IEM headphones where the balanced mono of an aux output is being matched with an unbalanced stereo jack?

     

    Maybe you don't notice the phase or there is that thing that people mentioned on the CQ settings that lets you set it as a headphone out (or maybe headphone stereo).

     

    * the P2 has a stereo switch and allows you to use it as a stereo.

    Agreed , which is why I am using a power bank USB output and standard 9v input .

     

    Yep, I have one of those (for my Boss XE1), sounds like a plan, but still leaves that horrible connector which you know is going to be the first thing to break.

     

    I have one but would be reluctant to gig it unless I had physically secured something to that power adapter.

    Might be worth getting a magnetic Micro USB adapter with cable to get around using Micro USB port on these, I have a couple of legacy devices I've been using the round style with and they work great. Only about £3 on AliExpress as well.

     

    Oh thats a good idea. Could glue that to the case!

    But, if what you say is correct (and I don't doubt that it is for a second!), that's making me think that the various earlier comments of: "you should never put an IEM cable into a line-level aux-out, without a headphone amp" as being an over-cautious old wives tale?

     

    Well, one thing, if it is not designed for it, if (for instance) I plugged some headphones into the TRS aux output of the X18 ihave, and it could drive it (and I have never tried, so can't say for definite), the ears would be inverted from each other - the tip and ring of a TRS aux are the positive and negative of the output, and the ground is just the cable ground. Headphones are tip to ground and ring to ground per ear, so in headphones when your left ear was pushing, your right ear would be pulling and viceversa.

    But irrelevant if the QC18 is designed to also run a headphone, I assume it fixes that.

  7. Also one of the reasons I wouldn't want that (regardless of being wireless, but if I wasn't), I need a real physical volume knob for partually to adjust as I go along, but mainly because at some point towards the end of the gig, our singer will somehow select the most tone deaf and loud woman in the audience to screech into the microphone with him, and I need to be able to kill that instantly!

    Quick question: there is some buzzing when i touch the pole pieces lf the P pick-up or my Piranha..

     

    Check the earth lead of your pickup goes to the earth of the rest of your bass

    I was a little worried from the some of the comments above that plugging a headphone into a line-level aux-out could somehow cause damage to the desk circuitry. But seems from my online research I can rest easy on that score, as the only issue is likely to be insufficient volume in the IEM ear pieces if the signal has not been subsequently amplified?

     

    Yes, I am very surprised it works, and I can only assume that A&H realised that people plug headphones into their mixers, so they decided to detect that and boost the output. I would expect that there is little risk of damage to any pro audio equipment because the companies would expect things to be done wrong, and also when you have an signal output it is designed to be laid over a stage and may sometimes get damaged and shorted, and that has to not break the amplifiers so there should always be be protection against that kind of use.

    And this  is why i said ‘most desks’ in my first post about this. Ive had maybe 20+ desks over time and not one would allow headphones to be plugged in to a send jack and get a decent level. 

     

    Agreed - but it would have never occured to me to actually plug a headphone in there. In fact if someone had tried that with one of my mixers they would have had a good kicking!

    I gig all my basses.  Beyond tribute bands, I don't see this rigid bass type to band/genre mapping at all.  

     

    No, I gig all my basses and never worried about bass type, although a 4 string has little use in my main gigging group. But the metal group has a lot of drop tuning, so it will probably live as a permanent drop D (or lower).

    mine's been pushed to delivery in week 4 now

     

    Mine is week 4 as well, but has been since a few days after I ordered it. But not an issue as it wasn't anything I actually needed anyway!

    I was meaning that the xr18 doesn't have any actual knobs or a screen that comes on when you power it up. I know too many people who say they've 'lost connection' for whatever reason or ended up cobbling a wired connection together for it.

     

    I have never actually lost connection (without using the internal network and a U4 aside) and I am not sure on the term 'cobbling' really matches connecting a standard ethernet connection, but ok! Yes, the CQ18 has a screen and hardware controls that are handy for setup, although I wouldn't really want to rely on that during a gig so wireless issues would presumably be the same. I would assume you could also connect to the CQ18 with an ethernet connection (at least I would hope you could), so you could use a hardware surface, which honestly always beats a table if you happen to also be gigging!

    This is leading to requests to tweak between almost every song so the 'main attraction' is the fact I can install the app on their phones and let them get on with it! 

    I've been in a band with an xr18 in the past and loved it, but was always worried that you couldn't tweak things on the desk. 

     

    You can tweak things on the XR18 - not sure why that would be different? You can put mixing station in a 'AUX only' mode, so they can only affect their own mix.

    There is, however, a personal mixer app for smartphones that replicates many of the same behaviours, and it's free.

     

    Indeed - but that is just adjusting standard AUX outs, which you could do on mixing station or whatever on the behringer, the X18 also has 6 outs (its what I use in my main group). Just does limit the number of stereo outs you can get from a mixer to 3.
