My connection form mixer to laptop is through a USB cable. It was the Audacity meter that was showing the sound coming through, although now that has also disappeared. I think I may have changed a setting like overdub and software playthrough and now I am not getting the audacity meter to move.
The mixer LED shows the mic is working but it only is registering abut -20 even though the slider is all the way up.
I should add that I also have tried 2 different mics, and 2 cables.
I have a logitech headset, and can record from that with no problem if I select that as the recording device.
I tried plugging the mixer into a different USB jack on the laptop, and now I have audacity registering the levels again, but when I record the wave for is tiny but there is something there. Everything is set to max volume.
I tried 2 different mics and cables in 2 different inputs. One is a Shure AXS1 and the other is a ABS Lute Pro Edition.
OK, I don’t see anything “tricky” about using those mics and they are both low impedance balanced with XLR connectors which is correct for a mixer (but wrong for direct connection to a laptop or soundcard) .
So… I’m out of ideas… Since the LED meters on the mixer are showing low levels it’s something related to the mics or mixer (not the computer).
FYI - You don’t need phantom power with dynamic* mics but it doesn’t hurt as long as you’re using the right cables/connections. I’d recommend you turn it off since you’re not using it.
Just some information NOT RELATED TO YOUR PROBLEM… Dynamic mics are like a speaker “in reverse” with a coil around a magnet that makes a little generator. There are no active electronics inside and they don’t need power.
Condenser mics work on a different principle and there is a little amplifier inside (like a pre-preamplifier) that needs a power source. Studio condensers ([u]like this[/u]) use 48V phantom power supplied by the mixer, preamp, or interface. Electret condenser computer mics run form 5V supplied by the soundcard, something like phantom power. Some stage-condensers have a battery inside and some run from “regular” phantom power supplied by the mixer.
There is a 3rd kind of studio mic called a ribbon mic. (It’s not used that much, but most pro studios have them.) They tend to put-out a weak signal so sometimes they are “active” with phantom-powered electronics, of if they are passive and they may just crank-up the gain or sometimes they use a special high-gain preamp.
