Hello,
I look for a sine generator with calibrated output level for use in live/PA systems. Something simple like a stick that you plug on XLR or Jack in order to check level with enough accurancy.
any field feedback on a commercial product or a link to a diy design are welcome.
Thanks.

Apparently not currently in production.
So try Shure A15TG

Look for the Minirator and minilizer https://www.nti-audio.com/en/products. They do pop up used and are probably ideal for your application. https://www.ebay.com/sch/i.html?_fr...nti+audio&_sacat=181939&_odkw=nti&_osacat=293
i was always partial to the Whirlwind Qbox myself.

A Phase-shift oscillator can do the job but having a calibrated and constant output level seems harder to achieve. How to get a level standard providing 7.775mVI think you could make a simple oscillator and imbed it into an XLR connector.
Okay, here's the story. I had level problems on microphone tracks of a mixer.
I first checked the input sensitivity setting on each channel. Then I swapped the cables and then the microphones, I ended up swapping the inputs. to find that the defect affected 3 tracks., The mixer was new.
That's why I'm looking for a generator whose output doesn't vary with battery wear.

so you have three bad channels on a new mixer?
i would be hard pressed do discern anything but gross differences in level between mic inputs...and without greater details like whether or not the inputs where fed all the same mics and checked with similar sources.
no chance pads are engaged? or that eq setting's are different?

what mixer are you having this trouble with?

thanks
Does the level vary depending on the impedance or is it adjustable?

I have a DIY product that may suit your requirements.

I built a 12-fader control panel for the Soundcraft Ui24r mixer.thanks

Hi altec9440,
Yes, the function of this black box is much more complex than that of Shure A15TG. The black box can be used as a simple audio test instrument.
1. Black box interface and functional information, here https://www.diyaudio.com/community/threads/simple-audio-monitor-signal-generator.412296/
2. DIY products are generally much cheaper. The black box price is 428$ (excluding express delivery costs), which is more expensive than Shure A15TG.
3. If you just DIY a box similar to Shure A15TG. The price will be more friendly
