My setup is as follows.You’ll also need a duplex sound card, but once you have that the Radio Shack SPL meter is suitable for measuring subwoofers, and response above that out to about 3 kHz or so. If you want to do full range measurements, that’ll require a calibrated mic. You would have to have access to a calibration file, or you can create one if you have a factory frequency response graph of the mic.

It looks like you may be able to, unless the Mac causes some issues. A line in and line out is required in order for REW to generate a calibration file for the sound card (or interface in your case). This is necessary in order compensate for any deviation from flat response that the interface might have. It looks like the RME has the connections capability to accomplish that. If not, you can probably skip the calibration – I expect a $1600 interface should have flat response.Is it possible to do a room check using this device [RME Fireface 800].
It’s no different from what you have, really. Since we’re typically dealing with home theater systems, our diagrams show a signal being sent from the sound card to the A/V amplifier, or powered subwoofer. That’s really no different than your situation, sending the signal from the interface to powered monitors.How is the setup done for this as the diagram in the setup seems to be for a Hardware EQ setup.
Only if you intend to equalize your sound system via external means.but i would also need an eq drvice to connect my sub and monitors to.
As noted, you must first have a frequency response graph of the mic to work with, typically supplied by the manufacturer. Open a Notepad file, and enter the deviations from response as they appear on the frequency response chart. The first figure on each line is the frequency, followed by a “space”, “tab” or “comma,” and then the deviation value. Using the graph below as an example, it would look something like this:How do you create a calibration file if you have a factory frequency response graph of the mic?
