Lo-cut switch and 10db pad...

[johnnypraze]

I understand that the low cut switch is but not so sure about the 10db pad.

When are these used and why?

The pad just cuts the source signal level down 10db so it doesn't overload. You'd engage the pad when your trying to record something that's really LOUD... too loud to work without the pad turned on. In other words... if it sounds distorted, overloaded, turn the pad on. But also remember not to use the pad unless you have too.

The 10db takes the input down 10db before you get to the mic pre. You normally would use this with things that have a really hot signal. Drum overheads and loud guitar amps are good candidates for the 10db pad.
The low cut switch cuts the lows below a certain freq. (it varies from mic to mic I believe). You might engage the low cut while recording vocals to keep any low end rumble or noise from getting in the signal.
Im sure there are more technical definitions but Im not a very technical guy. Someone else can probably explain better.

Say the average mic has a 80hz, 12db/octave roll off...

When recording vocals, when and why wouldnt you use the low cut?

<When recording vocals, when and why wouldnt you use the low cut?>

Very often you need this cut to compensate for proximity effect occured with close micing. Sometimes it is usefull (depending on voice, or instrument), sometimes is not. Your ears are the best judge.

BTW, usually it uses passive filter with 6db/octave roll off. They do it by changing coupling capacitor with lower value.

Studio Projects roll off at -6dB, where the AKG and Audio-Technica mics use a 12dB slope. I expect this from the more expensive models.
