These are the bars I am refering to

Hi Armand @Armand_RSA 

Welcome to the forum. Assuming you are using the analog input and not the Ultranet input, just below the XLR input is a switch. It should be set to Line, not Mic. What you are describing sounds like it is set to Mic.

Hi Paul,

Thank you for the response.

It unfortunately is not the case and I can confirm this is with the switch set to LINE. 

Extra note: Although the first level meter of the two bars shows clipping/limiting (the very top white square) it never has sounded distorted. When I noticed the 1.7 versions indicate a gain level much less than the 2.2 I figured it is just a glitch / bad programming, so I don't worry about the left bar when it reaches the top limit, as you can not hear any distortion articfacts in the audio.

Hi @Armand_RSA 

I would like to clear up the Limiters confuision, the "user" limiter is a brick wall limiter designed for level limiting. Think of it as the noise police feature!

With the user limiter set to zero, there are still seperate RMS and PEAK limiters designed to protect the drivers from over powering. These cannot be accessed by the user and are factory locked.

Regarding the input question, input sensitivity is Line +4 dBu, mic -22 dBu. This could potentially be clipped by a particularly "Hot" mixer output.

My reccomendation on the mixer side of things is to adjust the Master Level control so that the master channel level indicator lights at around 0dB at the peak level. This should allow plenty of headroom for peaks on the input to the IQ.

It is worth being carefull to not red line the signal input to your loudspeakers, even at low volume a clipped signal can be quite damaging to loudspeaker drivers as you essentially create a squre wave which makes the driver move in a way the builds up a lot of heat.

Clipping = Greater average power = More heat = Greater stress on the glues that hold a loudspeaker driver together = shorter life for the driver

Hope that helps, let me know if you have further questions.

Hi Alexander,

Thank you so much for the in-depth response Much appreciated. 

Great, I understand the User Limiter now better. Thanks for clearing that up.

Yes, you are very much correct. Softer but clipped (square waved) signals from the source/mixer unit are what destroys the drivers quicker. I always ensure not to send any clipped signals from my mixer to the loudspeakers.   

Just a last question, if my mixer output's at 0dB (top green on the DJM900) and the gain knob is set to 0 on the back of the IQ loudspeaker, but the first bar/meter on the IQ's on-board screen is reaching the top/"max", is it safe to operate like this? I find that the first bar reaches max before the second bar. In other words you can not reach the max output of the loudspeaker/amp (indicated by the second/right bar) before the left/input bar maxes out?

Kind regards
Armand

Nothing from anyone? 

One of the biggest reasons for moving over to a complete Turbosound IQ rig was the advanced DSP functions and especially the FBQ. But I need to better know how it functions so I can use it correctly and with confidence. 

Hi Armand @Armand_RSA ,

I think the reason no one has responded to your question is that most of us that use the iQ series of speakers do not use the feedback portion of the DSP. Back in the days when I had an analog setup (with an A&H GL2400 console), I used the Behringer Feedback Destroyers on the monitors. When I switched over to the X32, I continued to use the Feeback Destroyers until someone challenged me to learn how to properly ring out/EQ the speakers. I accepted that challenge and glad I did. The monitors sounded so much better and clearer (and had more life to them). Eventually I gave away those Feedback Destroyers. So I pass on the challenge.

Thanks for the response. 

The thing is I am a DJ, and run directly from my DJ mixer into the IQ's. I used to have a JBL EON rig that I ran through a DBX PA2. All the built in DSP options on the IQ's was the main reason I upgraded, so a non-functioning FBQ feature is somewhat annoying. 

Hi Armand,

On the HW:B FW2.2 IQ's the Learn function also does not seem to be working correctly.
Can you detail the issue here a bit more? Happy to report this to CARE and see if they can run some tests. We are certainly not aware of an issue like this.

Auto: Automatically sets as many filters as required. Whenever a new feedback frequency is discovered, the first filter will be released to attenuate the new frequency, and so forth.
This means that up to 8 notch filters will be added automatically, once the 8 are used if another feedback frequency is detected then the first filter will be overwritten by the new one.

Single: Activates the FBQ (feedback detection) functionality, up to 8 feedback filters.
Once 8 filters are deployed, it will not add or replace any more.

Hi @AlexLane,

Thank you for the info on Auto and Single FBQ modes. 

Last question on that, when I use Auto mode and feedback occures and the IQ "catches" that frequency, does it "release/lift" it after a while, or does it only reset when you power off the unit? 

HW:B Firmware 2.2. Learn function problem:
When you activate the FBQ Learn Function, it should output a few loud "clicks/pops" (So the unit can hear what frequencies are causing feedback) I have tested this on Firmware 1.7 and it works, but on Firmware 2.2 it is completely silent. 

Here is a picture of the feature I am refering to: 

Hi Barry ( @BronxBluesman ), 

Welcome to the community.  I'd recommend you check out Tuki Covers.  They have one specifically for the ip300 but I didn't see one for the ip12b.  They do have one for the ip15b so I'm sure they'd be happy to make custom one for you for what I've found to be a very reasonable price.  I've found their quality to be top notch.

Thanks man:

I have another question.

What is the best way to cable from my IP300 to my IP12B

@BronxBluesman 

Hi Barry, 

It depends on what mixer you are using and if you want the mixer to control the low end or use the crossover in the sub.  I'd probably start with a pair of XLR cables from the mixer L/R into Input A/B of the IP12B and then I'd take a pair of XLR cables from Link A/B on the IP12B into Input A on each of the IP300s. 

Hope this helps, 

Ken

I am using an Allen and Heath Zed 10 FX

Right now i am going from the board to the IP12B and then to the IP12B

Are you suggesting i go to the sub first?

By the way thank you for taking the time, i so not no much out this and am learning

@BronxBluesman 

Hi Barry, 

I usually go to the sub first to keep as much cabling as I can on the floor and to reduce the number of cables I have to run to the PA speakers.  Rather than running 2x XLR cables + power up to the speakers I only have to run 1x XLR cable + power if I come off the sub.  Electrically it's the same either way.

@JimDillon I have been trying to sort this myself for a while now as I own an ip2000 v1 system. What I have come to find out, the v2 system can get firmware updates and the v1 can not. I hoped it would be easily upgradable by simply installing the firmware. It is not. The firmware update is done via the Turbosound app which is the same version for both v1 and v2. The app can detect if you have the V1 or V2 system and if it's V2, it allows the firmware upgrade-I believe there have been 2 so far.

Pretty sure there is not, with limiter off.

Hi Ray ( @Mhound ), 

Welcome to the community.  As far as I know, neither TurboSound nor any of the other Music Tribe companies for that matter, publish schematics or services manuls for their products.  Your best option is to open a support ticket here: https://www.turbosound.com/brand/turbosound/support#googtrans(en|en)

You should receive an auto-reply email shortly after opening the ticket. If you don't, double check your spam folder.  That email will say that someone will contact you within one business day. Be patient as that's been more like a week ( or more) these days. 

Hope this helps, 

Ken

@wookiemIt's true, it's true, it's all true! Edit: Seriously as far as I know they have the same 10 year warranty as Midas

Thanks Gary

@Dae_dalus82 I cant speak to all the exact differences but when I looked (at turbosound in general) a while back, some models that had the ultranet port, did not include an ethercon port with it. I know the enclosre on some models differed in materials used and would suspect the speakers and perhaps the on board amps are different in some key ways.

Hi @Eldjmix1 

Best to get in touch with your local service centre for spare parts, link below:

got your solution?
