Remember to turn phantom power on if you need it for your mic. ![]() MUCH better than the laptop internal sound card (Sigmatel something or other).Īfter that, I hooked up the mic to channel 2. This cal file looked great, no feedback loop, and surprisingly flat. Plan B was to use an old guitar cable (unbalanced 1/4" phono) and link output channel 2 (R) to instrument/line in 2 (R). The cal file looked good except for the top octave, which seemed to get into some oscillating feedback. The first was stereo line out to stereo mic in. I tried to get a calibration file for it two ways. I will contact their tech support to see if there is a workaround to this. I did not need this for any of my uses, but it could be annoying if you do. Other users can access the device, and even set the master volume through the advanced audio properties (right click on the tray speaker icon). The main bug is that the admin account is the only one that can access the mixer panel for the unit. From an admin account, install the drivers without the unit attached, reboot, then plug it in. Installation is simple, but has a few bugs for XP. All the 1/4" phono jacks auto-sense balanced or unbalanced mode, which makes connections much easier. I believe the voltage is 48V, which is fine for the ECM8000.įor outputs, it has balanced/unbalanced 1/4" line jacks for each channel, a 1/8" stereo line out, and a 1/8" headphone line out with volume control.Įach input channel has its own level control on the front of the unit. It can supply phantom power to the XLR jacks via a switch on the front. As far as inputs go, it has two channels and multiple options for those:īalanced or unbalanced instrument/line in L/R ![]() It's also powered off the USB bus, which is nice if you use a laptop. Sturdy, clean lines, no extraneous controls, just the right number of connections. So, time for the review: the unit is heavy, but in a good way. Additionally, I wanted a smaller form factor than the Behringer preamp board some people here use which, while nice, is overkill for me since this is all I'll be using it for. I liked the idea of having the connections minimized: laptop to sound-card, sound-card to microphone. I went with this external soundcard because it supplies phantom power to the Behringer 8000 microphone, which is a monumental improvement over the RS SPL meter. I had done it by hand using a spreadsheet, RS SPL meter, and trial-n-error, and got pretty good results.īut as usual, education breeds unhappiness, so as I learned more about how good my room and system could sound I wanted better tools to know exactly where to apply the fixes.Įnter the M-Audio MobilePre. First off, thanks to everyone here who helped me pick, setup, and get meaningful measurements using REW over the last year or so.Ībout 6 months ago, I decided I wanted to get smart on room treatments and super-fine tuning my BFD.
