Hi folks,
I just wanted to touch base and let people know that I’m enjoying many aspects of my new Bose System both at home and performing away from home.
I am having a problem with feedback, and I’m just wondering if there’s anyone out there who can offer insight into getting volume to where it needs to be without haveing to endure pesky feedback.
Hopefully, if all goes well I will have successfully attached a picture from a recent venue where it became a real problem, especially after people started packing in. You can notice how I have the Bose setup, and where I am standing relative to the wall behind me. The mic was AKG D880 Emotion in case its relevant.
Kind Regards,
AJ
Hi AJ,
Please checkout the tips in this article.
See: Microphone Feedback in the wiki.
PS - I’m not seeing a picture.
No picture as yet (click on the 'edit' icon [the folder with the eraser] of your original post, then click on the "add attachment?" to bring in the picture -- just make sure the picture is re-sized to be less than ~800 pixels wide).quote:Originally posted by Ajellsay:

Hi AJ
We had all the feedback problems you had and spent a lot of money and time experimenting, and it is very simply fixed.
Use “anti-feedback” mics like the AKG D5 and set your gate at -25dB, and SING CLOSE TO THE MIC AND LOUD!!
Which is the advise that Bose give on the Wiki.
Noise gates - what do you do between songs when you want to talk to the audience, seems to me you need to be able to turn off the the gate and reduce the volume, a bit fiddly unless I’m missing something…like a sound man?
Hi thebluesvolcano,
If you using a T1® and have effects (e.g. reverb, delay, modulation) on your vocal channel during the song, you probably want to turn them all off while talking to the audience. The T1® FX Mute button for each channel lets you do that.
It may seem like a foreign concept, but I have taken to keeping the T1® close to me while performing. I prefer to attach it to the microphone stand. Others put it on a separate stand. Either way, it has become quite natural for me to use the T1® in the same way as I use my guitar’s pickup selectors, volume and tone controls.
But back to the Noise Gate: With some experimentation you can probably find a setting that will allow you talk comfortably to the audience without interruption from the Noise Gate. It will take some trial and errot to find a value that shuts down the microphone when you are not using it without otherwise affecting your vocals.
If you find a setting that works for you, would you let us know?
Thanks.
I am still trying to get the hang of using the gate to eliminate feedback, I have resorted to placement to take care of feedback issues. The problem for me is that when the whole band starts playing, the sound pressure is enough to open up the gates on the mics and honestly we really aren’t that loud, it’s just that we usually play fairly small venues so all the sound sources are crammed together which creates a cumulative effect for the vocal mics.
I want to be able to sing as opposed to yelling or screaming, my lips are pretty much touching the mic the whole time. I do project when I sing but I like to finesse a song through the use of dynamics and articulation so extreme gate settings are not the answer for me. I’m not giving up on the idea, just saying I haven’t found the sweet spot yet.
I’m sure everyone goes through this but at sound check there are usually patrons in the club so no one seems to play as loud as they do when we actually start the show. Especially the drummer which begs the question, if they can play soft during sound check…??? Bottom line is sound check is never really a true expectation of conditions when the bar fills up with people and you start to play for real. So I have been finding it difficult to try to make gate adjustments on the fly while playing and singing to try to find a sweet spot that works.
I guess the short version of all that is that the Bose system breaks the mold which means we all have to rethink what we thought we knew about sound reinforcement. It won’t happen overnight, lots of trial and error, time and patience. Keep experimenting, you’ll get it.
Hi PatMcNabbb68,
Thank you for joining the Bose Portable PA Community.
Just have time for a quick fly by (happy long weekend).
Please check out this article
There are some tips about using effects with the T1. You can probably adapt some of those ideas to the TouchMix 16.
Do you have a picture of the band performing with the L1s? I'd like to understand where you have the L1®s positioned.

I will see if we have a shot from our video session. Thank you for your quick reply. I love the sound of my speakers and the portability. I carry everything myself and set it up myself. Not bad for a 68 year old.

Hi patmcnabb68,
Thanks for using the Sketcher.
I use two L1 Model II units and two B2 subwoofers.
I know it seems counterintuitive, but I would pan the lead vocalist's microphone hard to one side. You'll get more gain before feedback, and because the L1 Model II has such wide horizontal dispersion, the audience will still hear the lead vocal. I would pan to the system on the right in the sketch.
Carrying that idea further, I would also pan all the inputs hard to one side or the other. Check out this article: Cocktail Party Effect

Too high Mic/Vocal compression can also cause feedback.
Too high Mic/Vocal compression can also cause feedback. Too much Gain also.
Thank you for these great suggestions. I'm pretty sure we had the compression all wrong on our first gig using this system and we adjusted the gain incorrectly. OK, we did about everything wrong we could do and still survive.
Hi Arno
i was on site yesterday and i want to share with you some problems we are facing with CSB:
we are using ESP-1240 with CSD 4.4.2 and CSB 2.2 on IOS devices.
1- we have CC-64 on site, if we set the volume for a zone by CC-64 to (-5 for example), this value will be the maximum that the application can reach on 100%
2- as shown in the attached video, if i chose airplay source on a gym and then i chose airplay on garden, if i back to gym, the source that i have select disappears
3- if i opened the CSB file directly, it's showing a blank page, i have to open CSB and then open the file
kindly
ohh good to know, actually i don't know why my colleague used parameter to select source. anyway what about point #1
Hi Abboud,
When the connection between the ControlSpace product and the remote device running CSR (connection icon should not be greyed out anymore), we poll the status of the open canvas.
Can you tell us a bit more:
-What kind of device are you using?
-Which version of OS is running
-Which version of CSR are they using?
-Can you send us the design file for testing?
-Are you testing it with a local WiFi router or on a company network?
If you have additional information, please let us also know.

Hi Abboud,
You used the Psets for source selection an only one Pset can be active at a time. So if Pset 1 is active and you invoke Pset 2, Pset 1 will go off.
In you case it would be easier to use the selector blocks in you design for source selections.

#1: I notice you use gain blocks and groups with the same name and some gian/groups are out of sync.
Could it be that you used a group in the CC-64 and a gain block (with the same name, but out of sync) in CSR?

I have run into a possibly related issue. Feel free to delete it nice as needed.
My designer and I set up a remote app with source, volume and mic control. Some of the mic zones, and playback source volume, were at one point combined. To make the change as small as possible we decided to merge multiple gain blocks into groups, and then swapping faders and mute buttons where relevant.
At first it seemed ok, but when we tested thoroughly we discovered the grouped gains and mutes in the app didn't actually send commands. They received and correctly displayed levels and states when they were recalled from PSets, as well as when controlling directly from CSD.
We ended up with a functional workaround, by merging the gain blocks into matrices, followed by a single gain block.
Please let me know if this is an isolated issue, or if you need the source files.
Hello Peter,
Can you send me your design files, so I can test it on my side?
Which version of CSR and CSD are you using?
