U3014, A03, low noise level, Nov 2013

After receiving insurance through Dell Small Business. the U3014 all new have at least Rev A03, I ordered another to replace a fading 3008WFP.  After you received yesterday, I ran through the installation program and checked everything, including the USB3 and operating an internal decoder 2-channel audio.  I use the standard Dell AX510 sound bars on all my monitors to reproduce audio embedded with HDMI signal sources and nVidia Quadro Display Port K5000 than card outputs.  My other Dell, a new U2713H and an old 3008WFP monitors, work very well with their AX510 sound bar.  However, the same inputs HDMI and Display Port on the U3014 produce a less than 13 dB audio output.

A sound signal to 1/20th of the normal level makes its unusable AX510 with my new monitor U3014 bar.  Since I do HDTV edition, I need to use the U3014 to monitor the video and audio from my reading of BlackMagic Decklink 4 k Ultra HDMI as long as the audio embedded on my nVidia Quadro K5000 video card display Ports.   (BTW: USB3 parts work fine)

Everyone knows a similar problem of audio low on their screens of U3014?

This is an update to the original message of low audio output:

After contacting Dell Small Business Tech Support.  Dell sent me a replacement U3014 monitor via FedEx overnight.  After that I connected to my system and it turned on, I was pleasantly surprised because audio Digital Envoy through the HDMI ports and DP was NORMAL.  In addition, the display of U3014 had no corner visible backlight line, as it is 'normal' for this view.  But the strong "glow" IPS limits how close you work at the screen of the monitor.

However, after about 30 minutes the audio level fed by the Audio Jack Out U3014 for Dell AX510 went way against.  A different sound bar did NOT help.  When I plugged the Audio Out jacks on my U2713H and U3014 monitors to the audio meters of Sony Sound Forge Pro 10 six channels and I saw the same 13 dB drop in the two channels that the first U3014 suffered.

The two U2713H (audio channels 1 & 2) and the U3014 (channels 3 & 4) were fed the same HDMI DirecTV output. The recorded maximum concentrations are at the right end of the Green level bar poster.   These show the difference between the output taken on two audio monitors.  The output of U3014 is 13 DB below the output of U2713H.   When turned on the U3014 was identical to the U2713H!  After 30 minutes the audio output of U3014 level has dropped.

My guess is that something in the digital audio receiver has failed.  And, since the two U3014 monitors are close in the serial numbers, this failure is likely to happen all U3014 in the same factory lot.

Given that most of the users of U3014 is not to monitor the audio digital integrated on the inputs HDMI or DP, there are not too many reports of this problem.  Those who intend to use the U3014 of audio and video surveillance on HDMI or RFP decision taken entry need to check this problem.

  • Keyboard slow and low noise level on a Satellite A110-178

    Hi all

    I have acquired A 110-178, which for me has the right specification.

    However on the first day, I feel that the use of the keyboard gives me problems. It isn't as I type like a pro, I have the 2 fingers way, but when I type most of the time I really make changes because some of the letters will not appear as they skip the step of what i type.

    It should be possible in my view with a laptop like that, just press the keys and have no kind of hit them.

    Is there a way via settings or to make some adjustments?

    Also, the sound is not good... I put it all on the maximum level, but for example Youtube things have virtually no noise while on my desk I never face ny problems or I had with my previous laptop, also a Toshiba.

    I'd be happy to hear your thoughts.

    Hi dutchrob,

    regarding your keyboard: looks like you need to contact a local servicepartner, cause I had the same problem with my Tecra and it was a failure of the keyboard. They will exchange the keyboard if it is really defective.
    This thing of sound can be perhaps a driver related problem, so why you don t try to reinstall you sounddrivers?

    Have a nice weekend

  • Satellite A100-259: low noise level

    I just bought an A100-259. that seems to have the reading levels of low level on all sounds. I turned all maximum devices but the level is still not sufficient on the speakers. The earphones are about right.
    Any ideas?

    Hello

    I found the details of the A100 and there should be installed virtual sound application.
    I recommend you to check the parameters in this application.
    Play around with these settings and try to change it.

    In addition you will also find a reltek affect his manager in the control panel.
    Here, you can also change the audio settings which are responsible for the sound quality of the speaker.

  • Low noise Satellite A100-998

    Hello

    I bought a satellite A100-998 with Harman/Kardon speakers, even if the computer laptop screen at the store had a remarkably high compared to other brands, the machine I bought product a very low sound, although the dial at the front is turned to the maximum & all software orders are set to high? A

    NY suggestions? We advised me to update the audio driver, would this help (but why a laptop bought a few days ago would need to update its drivers?) and I need to update the Bios also, pls help as the low noise is upsetting to me much (not what I expected at all).

    Hello

    I think that the volume on the laptops is a matter of opinion.
    It is really not easy to tell if it s a bad or normal setting.
    Why do you offer that the sound is low? Compare you the sound properties with other laptops?

    Anyway, perhaps you're using really bad setting and only a switching of some controls would increase the sound quality.
    AFAIK the Realtek HD Sound Effect Manager has been installed on this laptop. You should find it in the control panel.

    Here, you can try to change some settings. Wave volume, volume of the CD, everything is possible.

  • Why NOT-9233 with IEPE micro report 39dBA as a minimum noise level?

    Hello

    I used an ACO Pacific 1/2 "microphone and preamp (7052SYS) with cDAQ IEPE and 9233 IEPE module. The microphone of the COA is very similar to the 46AE G.R.A.S. (50 mV/Pa) but with sensitivity 20 mV/Pa. With this facility in a hemi-anechoic room, the NPA is reported as on 39dBA (using audio and vibration standard "meter" VI). Again, the third laboratory signals Analyzer reports the House about 25dBA. I partially checked installation OR with a 1 kHz, 114dB Sizer. Putting in place OR says about 114.3dBA. We are so on the money there.

    Is there a background noise on the 9233 I treat? Any thoughts? Recently, my company has built its own hemi-anechoic and we love the tools NOR. We had hoped to use the newer 9234 with a chassis cDAQ since the 51.2 kech / s is sufficient for our range of 20 to 20 kHz. We already use it cDAQ widely here.

    Thank you

    -JD

    The 9233 plug:

    Integrating the density of noise:
    Weighted power = (factor of a power of weighting for bandwidth) * (bandwidth) * (noise level) ^ 2
    Weighted power = (0.53) * (20-20000 Hz) * (400 nV / sqrt (Hz) / 20 mV / Pa) ^ 2
    Weighted power = 4.26u Pa ^ 2 rms
    (Weighted) Leq = 2.06 m Pa rms DB 40.2 (a) ref 20u Pa

    Calculation of noise at full scale:
    FS = voltage range / sensitivity
    FS = (5 / sqrt (2)) V rms / (20 mV / Pa) = 176.8 Pa rms = 138.9 dB ref 20u Pa
    Noise 138.9 DB ref 20u Pa - 95 dB FS - 2.73 DB(a) = 41.2 DB(a) ref 20u Pa

    So the fact that you are reading 39 DB(a) indicates your 9233 noise meets the specifications. There is always a problem that it takes efforts to better reflect the range of the signal on the input of the 9233 range. You can add some signals external conditioning apply pregain (20 dB) to the microphone output before the 9233. You also have some other options material DSA that include the input gain.

  • noise level measurement

    Hello

    The attachment is a recording of an audio input with no signal applied. I need to know the level of noise in db. I have the latest labview but do not have the vibration and audio tools kit. According to some of my coligues with other analytical tools that the level is to-30 dB. I'm not sure how to code this in Labview. Help, please.

    Note:

    I had to modify the .csv file type to uplad to this site, but it actually is a .wav file.

    Thank you

    Hi PercyH,

    You should be able to use the express vi measure spectral to the basic analysis of signal noise levels.  There are also several signal analysis tools that come with the LabVIEW base package in the range of Signal Processing.

    I hope this helps!

  • Windows 7 turns off without warning when you reach the low battery level

    I was using a laptop HP which is upgraded from a family of OEM/RTM Windows Vista Edition Premium x 64 SP1 installation to a cleaning of the Version FULL of Windows 7 Home Premium x 64.  When I used it on battery it takes 25-27% left and it close it self of without any warning that the battery was low.  Then, when I connect it to the power cord and turned on I got the message of recovery Windows error that we will choose between the SafeMode / SafeMode with network/Safe Mode command prompt / start Windows normally and I chose to start Windows normally.  I went in the power and clicked Options on advanced settings for the power management that I use and when I extended battery it says:

    Critical battery action
    On battery: hibernation
    Plugged in: do nothing
    Low battery level
    On battery: 25%
    Plugged in: 10%
    Critical battery level
    On battery: 5%
    Plugged in: 5%

    Low battery action
    On battery: do nothing
    Plugged in: do nothing
    Reserve battery level
    On battery: 7%
    Plugged in: 7%

    Why have I not a warning when he got low battery level and why it automatically shut down and give me this error message.  How can I fix it.

    It could be that your battery is bad.  With my laptop, the battery lasts a few minutes, and if it passes underneath of ~ 20%, it stops instantly.  So, I just put the battery level critical to 25% and the hibernate on battery battery critical.  Windows 7 should be smart enough to tell you if this is the case (at the bottom left icon will have a red x through it, and if you hover over the battery icon it will say "consider replacing your battery."

  • Noise level of the SRW2008MP?

    Hello!

    Does anyone have information on the level of noise produced by the SRW2008MP?

    In addition this switch is quieter when idle or rather the noise level will always be

    the same, no matter the temperature of internal components?

    Used stock output from Dell could be any revision, (A00, A01, A02, A03). There is no way to know when you place your order to Dell making.

  • Tecra S11 - low sound level

    I recently bought a S11 and as a former owner of the Tecra line, I was very disappointed with the Audio level. I realize that the S11 is a Business and not a multimedia machine, but I have to sit nearby and make sure that there is no noise in the room to hear the speakers edge.

    Is there a way to fix this? Even 50% more audio would be a huge improvement.

    Hi Pman,

    I m not a Tecra S11 owner but I can't imagine that the sound level is so low that you described.
