Noob Needs Help

Hi guys this is my first post and I could use some help. I want to measure the room my 2 channel system is in,
hoping that I can make some improvements. Also to know what's going on in my room. I have SPL meter and a laptop windows vista I think, I believe I now need and external soundcard? I saw the M-Audio one in best buy is that the one I need? My main objective here is to try and add a tiny bit of bottom to my system, I am using an SET amp 2 wpc so I need to know what I am doing here. Can someone point me in the right direction? Thanks.

Jay

Hi Jay

More info for the experts, what sort of SPL meter (brand and model) do you have keeping in mind the SPL meter is accurate from certain frequencies.

The ideal is to buy a calibrated mic (Dayton EMM6 or Behringer ECM8000) from Cross Spectrum (for accuracy) + a external soundcard like you suggested.

Re: Noob Needs Help

If your laptop has a line or headphone output and a line input then you will be able to use those, really only need an external card if the laptop doesn't have its own audio input and output - on some laptops they share the same connector so can't use both at once, but if you have separate connections you should be in good shape.

Hi John,
The only thing I see is it has a mic/headphones they are next to each other along side the SPDIF plug. I though I read that you shouldn't use the mic on a laptop because of the gain?

Re: Noob Needs Help


Welcome to the Forum, jc! As I understand, many laptops these days have provisions to change the mic input to a line input. If yours can do this, then you’re good to go for measuring low frequency response in your room with the Radio Shack meter, as long as it’s one that we have a calibration file for. If not, let us know and we can explore other options for you.

Regards,
Wayne

I’d suggest checking the manual for info on switching the mic input to line. I don’t have a HP 9000, so I’ve pretty much given all the info I have.

Wayne
