    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,  I got an email about your new product C210 column speaker.  I was literally about to listen to/possibly buy some other brands but thought I'd hold off as I ahve a Behringer mixing desk, and thought I'd check it out.  Looked up ALL the websites for the suppliers listed...nothing...no one has details on the weight of the unit, spec, costs, when it's all going to be availalble? Anyone know?  

    Thanks in advance.

    Anyone have experience with the VXP series? Would two VXP12 be suitable for an acoustic duo for small gigs?

      The VXP12s are my favorite self-powered speaker we offer. Within our umbrella of brands, the Turbosound iQ12 are also nice and well suited for an acoustic duo, however Tannoy's dual concentric drivers in the VXPs are on a whole other level of clarity. Just know if you plan on pole mounting them you'll need these

    We have an upcoming conference with 60 participants in an overall space of 105' W X 18' D X 10' H.  Orientation may switch with screen and speaker along short wall.  Spoken word only.

    I wanted to find out if this system might suffice for this volume of space?

      Hi Pavneet ( @usonianhorizon ), 


       


      Welcome to the community.  It should work just fine although you'll want to consider proper speaker placement. Those room dimensions are almost a hallway so I definitely would present from the short wall.  Assuming the audience will be sitting in chairs, you'll need about 10 rows of 6 chairs each which puts the back row at least 30 ft from the front row. No problem for a 500W PA. 


       


      I'd recommend you get a pair of speaker stands and also consider the ULM wireless mics if the presenter isn't standing at a podium. Most presenters, particularly those with less experience, prefer the wireless freedom. However, you need to make sure to place the speakers far enough forward so the presenter (and mic) never get in front of the speakers. 


       


      Hope this helps, 


      Ken

      Thanks for your detailed reply, @KenMitchell .


      Yes, we would like to use ULM mics, but haven't found an update to the dongle weakness problem posted on this video (suggested on the Behringer product page):


      Behringer ULM Ultralink Mic problems at Northern Beaches PA Hire


      Plus, I am not clear on the difference between the 200 and 300 series mics.


      Regards.

      • June 23, 2019
    • usonianhorizon
      RichardYClark Basically the 200 series use the USB dongle as the receiver. And yes it does stick out if connected straight into a USB socket on the back panel of a Behringer powered speaker. Answer. Use a short USB extension lead so that it can be kept flat to the back panel with Velcro or similar. The 300 series comes with a proper receiver rack with analogue audio out like any other traditional wireless mic.

      RichardYClark To put your mind at rest I only thought of it as I answered your post. I have been using it sticking out and liable to damage. Doh!

    We're using a pair of B115Ds as our PA system for our three piece band that plays rock covers in bars. We only usually put one vocal mic and a guitar DI through it, but occasionally we mic up the bass drum (but we're looking to buy a sub for that).

     

    My question is on where to set the level control. If I was using passive speakers with separate power amps, I'd have the power amps on full (ie 0dB) and then control the volume from the desk. With the B115Ds, does the same principle apply? Shoud I have the output set to Max and then control volume by limiting the signal from the desk? I guess the quustion is whereabouts on the dial is 0dB? What has confused me is the marking that says "Line" and then "Mic". Am I risking damage/distortion if I put a line level signal inand have the level set way into the "Mic" region of the control?Capture.JPG

      @McElviss 


      The best way is to first set a good gain structure on the mixer, set the output fader to 0dB and then raise the gain on the speaker to get the required volume level. Setting the speaker gain too high could result in distortion with line-level signals.

      RichardYClark

      Certainly yes to Rex's reply. But as a rule of thumb I have found that with Behringer mixers and various powered speakers I have found the 12 o'clock position to usually be a good starting point.


       


      P.S. Why are the latest posts not word wrapping properly all of a sudden?

    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.

      @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.

      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.

    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?

    Hi All,

    I'm thinking of getting a Behringer Europort MPA30BT to use away from mains power. However, I need to be able to charge it from 12v DC, USB or other DC supply when mains is not available. Is there a DC charging input on this unit?

    Thanks for looking, Geoff

      Hi Geoff @GeoffL 


      Welcome to the forum. The MPA30BT charges the internal battery from the AC input. Therefore the only way to charge it via battery is to use a sine wave type inverter.

      @GeoffL 


      Hello Geoff, welcome to the community.


       


      There is no DC power input on the MPA30BT. It requires 100-240 V at 50/60 Hz. If that is not available, you should be able to charge it from a 12Vdc supply through a small inverter like this.
