    Hi Music Tribe / Turbosound / Fellow Turbosound users,


    So on the Turbosound IQ series DSP screens there are two bars on the right of the screen indicating the audio levels. First is the input gain and the second is the output.


    I noticed that when running straight from a Pioneer DJM900 mixer, the input level reaches the "clip" level very quickly. (You can see it more clearly when using the Turbosound app on the laptop and connected via USB to the unit.) I now run with my DJM900 on-baord attunator always set at -6dB, but when not even getting close to any red led's on the VU meter, the input on the screen will still indicate it is clipping very quickly. I try to keep my levels mostly at the 0dB/top green LED, but this does not seem right. 


    This input level indicated on the IQ's screen (the left bar) is also post gain knob I have figured out, but it is almost impossible to turn the gain knob up till just under clipping (of the right/master level meter) without the left level meter clipping much quicker, this does not make sence at all. Or are the two level bars on the DSP screens for left: pre-DSP and the right indicating post-DSP?

    There are nowhere any clear info on what these level bars indicate.  


    Then I noticed something the other day when I used the (HW:A FW1.7) Turbosound IQ's together with (HWB FW2.2) IQ's.  The rig was connected in stereo and in series with the full range signal via XLR from the mixer going into an IQ18B bassbin (Fw 2.2) and then to an IQ15B (Fw 1.7) bin and then lastly into an IQ12 (Fw 1.7)  top. On the Fw 2.2 units the input level were constantly much higher than on the units with Firmware 1.7. All the rest of the DSP settings, gain knob etc where set the same, so this was very odd.


    Also, there is a big difference in the levels when using the DSP limiter at 0 and at -1. (Much bigger than the difference of going from say -1 to -2, and to -3 etc...) so I prefer not to use the limiter as it sounds like it reaches it's threshold way to quick. When the limiter is turned off there is much more headroom. 


    I think the engineers should just check the on-board DSP level meters (input/left side and output/right side of the on screen bars) as well as the DSP limiter behaviour.

    Nobody could also answer my question regarding if there is still a limiter active when the on-board DSP limiter is set at 0?
    (I want to ensure my drivers/amps stay protected, but setting the limiter at -1 looses too much volume) 



    Other than that I am extremely happy with the Turbosound IQ series. I hope I can get answers or a response for the above and sorry for language errors, English is not my first language. 

    Regards

      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

    Hi there,

     

    I would just like to enquire on more information about the FBQ feature of the DSP on the IQ series.

     

    When using Auto and mode on the FBQ feature, do the filters get lifted after a while or how long do they stay activated? 

     

    Can someone also more clearly explain to me the difference between the Auto mode and the Single mode?

    Does Single mode only filter a maximum of 8 frequencies and thereafter nothing? 

     

    The manual says 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.
    Single: Activates the FBQ (feedback detection) functionality, up to 8 feedback filters.

    On the HW:B FW2.2 IQ's the Learn function also does not seem to be working correctly. 

     

    ~ Thanks in advance for any answers / replies 

    Regards

      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:

    I just purchased 2 IP300 and 2 IP12B sub's

    I am looking for covers for them and do not see any on the Turbosound web site.

    Love these speakers and want to protect them

      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.

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

      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.

      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

      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.

    Hey all,

    I have been using the IP2000's for a few months now.   They sound great....until I have to push them for a bit more volume.  I have a small band with pre recorded tracks for Bass and Drums...we sing and play guitar over these tracks.

    I seems there is a general agreement to set everything on the speakers DSP to "0" to use these as a PA speaker with a mixer.   However, it seems there is not a clear explaination as to how much input to use to optimize the output of the speaker.  

    The ouput runs hot and pegs out very quickly...to the point the system will cut out or clip.  I think Turbosound should do a video addressing input and output settings.  On the DSP display it will show the input at two bars and the output quickly goes off the scale.   It is hard to balance these two settings.  

    Does anyone have their own experiences to share?

    What is the differance in Ip2000 ver 1 and ver 2?
    If it's software is there an upgrade for the software?

      @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.

    Hi,

     

    When the limiter is off, is there still a master limiter activated as to not push the system beyond it's capabilities?

    I'm very frustrated because for over 2 hours I've been negotiating this site with no answers, and going in circles answering and re answering the same questions but no info from this site.  

    All I want to know is where to get some technical info such as schematic or service manual to repair this Turbosound IQ15B with blown parts on the amplifier and power supply boards.  Or where to get replacement boards..

      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,

    I own 2 15 inch siena tsp152-ans.  I was going to buy a pair of 12 in loudspeakers but before i do i was wondering the differences between the siena, nuQ, and athens product lines.  The athens have different dispersion options but other than that i am unsure what their main selling points are.  If i go by frequency response and max spl then the sienas are the best bet.  The other two lines are more expensive and i wonder why that is?  Thanks for any help anyone can provide.

      @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.

    Does anyone have a parts manual or parts list? I had my speakers bashed with a bat (client bought me new ones) and now I'm trying to get parts to fix?
