Har nylig kjøpt CQ18T og skal koble denne mot høyttalere Bose L1 Pro32 sub 2.
Om volumet på Bose settes høyere en kl 10 suser det veldig i høyttalerne.
Har forsøkt mute alle kanaler også Main L/R men susen er der fortsatt.
Forsøkt å koble bare høyttaler ledning til en stk Bose uten at andre ledninger er koblet til.
Forsøkt med XLT/Jack balansert plugg. Da blir det mindre støy men noe av lydbildet blir dårligere.
Bruker balansert kabel XLR/XLR til vanlig
Det er ingen kompressorer, Gani elle annet som står på. Har til og med tilbakestilt CQ18T til fabrikkinnstillingen og forsøkt.
Noen som har tips på dette??
Interesting. I have the same issue with a Bose L1 Pro8.
I found that using a higher quality XLR cable from the CQ Mains to the Bose Input 2 made a sizeable difference, though the problem isn’t eliminated totally. Plugging all power into the same source seems to help as well. I use a Middle Atlantic PD-915R.
I still can’t push the Bose past about 50% without a lot of hiss being generated, but for the places I play this isn’t a massive issue. Would be nice to find a real solution though….
The XLR inputs 1 and 2 are clearly intended for microphone level signals only and are therefore far too sensitive for your line level signal.
Therefore, use an adapter to a balanced TRS jack plug to connect to input 3 = Aux, which is intended for line level signals.

Problem solved. Thanks SQuser!
This is a perfect example of exactly why musicians need sound guys….

Takk for tilbakemelding men dette fungerer ikke så bra på Bose L1 Pro32 sub2. lyden blir veldig mye dåligere om man bruker Balansert TRS Jack inn på Inout 3. har forsøkt dette men lydkvaliteten er ikke det samme. Har også Bose L1 pro8 som dette fungerer bra på. så det virker rart. noen flere forslag eller flere erfaringer hadde hvet fint. På forhånd takk
You seem to be able to read or translate English, so why can’t you also write or translate in English, like everyone else here in this forum?
English isn’t my native language either, but I’m trying my best.
There are so many options these days.
It’s not a guarantee of answers, but your chances would definitely increase.
Actually, your question would be better suited to a Bose forum.
Bose has always had to do things a little differently, and I think they often didn’t do themselves any favors by doing so.
If your device isn’t defective, which I assume it is, and Aux Input 3 still sounds “bad,” it’s quite possible that you’ve consciously or unconsciously changed this channel’s EQ (see picture - all in one knob - oh dear).
Both parameters should be set to “Linear” (unfortunately, there doesn’t seem to be a simple reset for the entire speaker).
If the input is set to Linear and you are still dissatisfied with the sound, simply use your CQ’s EQs to adjust the sound to your liking.
Thanks for the compliment. I can use the translator program, let’s hope it translates correctly. I’ve been in contact with Bose support but they showed less than what I do, no help there. I’ll try to adjust the eq but it shouldn’t be necessary, you have to send it from an i pad straight into the mixer without using eq on the channel. I’ve used this earlier on UI16 without problems.
It seems so.
I don’t understand it, but it doesn’t surprise me either.
No adjust - set it to flat.
If you had the UI16 completely flat - both input and output channels (!) - and connected it to Aux 3, then the CQ completely flat should sound the same on Aux 3.
If you connected the UI16 to Input 1 or 2 and used any tone-matching effects, then it was just luck that it suited your taste, but it’s not a professional solution.

Hi thanks for all the tips or advice. have now tried a new cable into the input marked 12 in the picture. tried with EQ Line and EQ Off. Both inputs make noise when the volume knob is turned over 12 o’clock. This happens because Maim L/R is not actively muted. no cables from other sources are connected to the CQ18T or Bose L1 pro32 sub2. Quiet until the Bose is turned over 12 o’clock then the sys starts.
I still don’t believe your Bose system has any defect.
Your situation is essentially the same as webhiker’s:
Your XLR inputs 1 and 2 are not suitable for connecting a mixing console because they are far too sensitive for its high output levels.
This is perfectly logical for the reason mentioned, and with properly functioning balanced XLR cables, you should always get the same results, not have the noise start at knob position 10 one time and at 12 o’clock the next.
The noise you’re hearing originates in the output circuits of your console and has nothing to do with its mute function or connected devices.
Furthermore, any normally leveled output signal from your CQ will hopelessly overload the Bose’s undamped XLR input (there isn’t even a gain control to adjust it).
Therefore, also you should use an XLR to balanced TRS jack adapter and use the dedicated Aux input 3.

To add to this, the term for your favorite search engine here is: gain staging.
Every audio tool has a gain range in which it operates well. If it is driven too loud, it will clip/distort internally, if it is too quiet, noise (or even digital artefacts) will became prominent in the output signal.
So you need to find an input or setting on that Bohse system that works well when the output meters of the CQ mixer are up around 0dB.
