The setup I put together is a mixer by Behringer QX1202USB and a few microphones in the range of 20-25 € (Soundkinh EH 002, Superlux D103 13X, Dehringer XM 8500 ULTRAVOICE).
Two microphones came with cables (XLR2XLR, XLR to 1/4 jack) and the third was shipped with no cable. I hooked up two microphones and noticed the levels are very low and I need to turn volume up on individual channels practically all the way up, incl. the main level switch and also boost gain, thus adding a lot of ambient and white noise.
My initial thought was the cheapish microphones but then I noticed this greatly depends on the cable. The above described effect is less pronounced in the XLR2XLR cable, irrespective of the microphone.
Can someone take a stab at what is going on? Do I need an extra preamp for microphones? Would upgrading to better cables help? Is there a setting on the mixer I'm missing? Are low levels for microphones the norm?
