Hi,
I bought Chord CM05 microphone on amazon - it looked as reasonably quality mic for a good price. Since it is my first condenser mic, I just wanted to try it and bought a cheap phantom power from aliexpress.
Unfortunately I realised that the XLR cable I had (just spare one, I never used it before) is unbalanced one - only two wires, pin 1&3 interconnected. That means Chord mic got 48V on pin 2 and 0V on pin 3 and 1. I realized it soon (under one minute) after I didn't hear anything on the output.
When I obtained correct, balanced cable, I'm hearing only noise when I switch phantom power on, no other sound. I checked that there is really 48V on both pins 2 and 3 (to pin 1 of course), I measured about 10kohm between pins 2&3 on mic side of phantom power (while turned off). Also I tried a dynamic mic which passes sound through phantom power supply.
Spec of CM05 says about FET preamp built in. Can it be damaged by 48V difference between pin 2&3 ? How can I possibly berify it?
My testing setup is:
Mic - balanced XLR cable - Phantom Pwr Supply - XLRto3.5mmJack - mobile phone with recording app
This setup works with dynamic mic (with or without PhPwr). I intend to buy something better (phantom power & recorder or PC interface), but I am on budget, so I go step by step, began with mic...
