Help on mixing consoles

Posted on

I was given a few questions from my music tech class and can't find the info I need. Could anyone please help?

The first question is 'Condenser microphones require a polarizing voltage and power for their built-in amplifiers. Sometimes provision is made to supply this voltage directly through the microphone cable; a voltage, which, incidentally, is placed on both signal lines with the same polarity to create a net zero DC potential across the coil. What is this polarising voltage and power called?'

I'm assuming this is phantom power. The next question is 'Consider the text above. What problem might you face without a good knowledge of what a mixing console can do?'

The only thing I can think of is not knowing what switch / which button to hit when... which I'm guessing is not correct lol.
Could you please help?

The first questions, I not sure.

The second questions.You wont know how to control the gain input or any volume controls and can blow your soundcard or whatever your recording too.Also wouldnt know what buttons to press or turn and wouldnt know how to use the EQ, Pan, or FX.

yes, 1 is phantom power at +48 vDC

2... well some consoles have a +48 button, some have a mic pre pot that you pull out or push in. some like the C24 have a phantom power button in banks of 8. i guess not knowing the console will cause confusion, especially if you pick up a cheap mixer that only has 4 i/o with phantom and you need to utilize a deca tree for 5.1 and require at least 6.
