Yep, same mic as the MXL57/63/1006.EddieRay said:I've heard that the GXL mics are very similar to MXL (Marshall) mics. They don't get mentioned very often in these forums though.

And gee, board pics are getting popular on the board now. Maybe I should take some photos myself...
Sorry, I meant to imply that the circuit was the same – not the mic, although I’m betting they have the same capsule too. The boards may be different but the circuit looks basically the same to me: FET into bipolar phase splitter output stage with a voltage multiplier to increase capsule voltage. The 1006 might have better capacitors.Flatpicker said:Yep, same mic as the MXL57/63/1006.

Definitely not close enough to the MXL 1006 to be regarded as similar.
I've got pics of the 1006 boards and they are basically the same. Only difference is the GXL has a high pass switch and all the electrolytic caps are on the bottom board instead of two of them being on the top board. The switch doesn't make sense because the ones on the CAD web site don't have this.Sklathill said:I don't suppose your PCB image library is web-based?
And should I take a look at my 1006 and take pics?
No, they don't mention it, but it's there in the mic. Just an added bonus.Flatpicker said:The switch doesn't make sense because the ones on the CAD web site don't have this.
It's a high pass filter, aka "bass rolloff." You would engage it when you want to de-emphasize the bass frequencies of your sound source - if something sounds too "boomy", or to counteract proximity effect.mndog75 said:What does the hidden switch on the circuitboard do???
