MXL V67GS mic not recording at full volume, ideas?

Hey dudes and dudettes, quick question…I bought a MXL V67GS and it’s not recording at full volume. When I plug an SM57 in, it records perfect, so I’m wondering if the phantom power is not strong enough? I’ve read that moisture can cause problems with this mic but it sits in a room with soundproofing panels and from what I know, not too much moisture. I do like this mic and was wondering if anyone could help out? I’ve also heard putting the mic in some rice to extract potential moisture may help? It’s only been used maybe 8-10 times with mic popper protection so lips and breath have barely been inside this.

I use an Mbox and Logic Pro X, but I’ve had no issues with a dynamic SM57 or doing guitar tracks.


There have been tricks played with Phantom Power. A “proper” phantom power switch generally says 48v, not “ON” and generally there is a switch. There was one mixer that had no switch and after some very difficult digging it turned out the Phantom power was a little-supported 12 volts. No, it wouldn’t run a 48 volt, higher-end microphone.

Just to cover the bases, the microphone is side-fire, you don’t talk into the end like an SM57, and it’s cardioid which means only one side of the microphone works. Are you sure you’re talking into the right thing?

Never expose a microphone to dust or anything with tiny particles. How many posters complained of moisture? I’ve never heard of a condenser microphone expiring from high humidity, even the older ones that run the capsule at hundreds of volts.

Microphones are provided with sensitivity postings. If you put this much air pressure on the microphone, this will happen. You can compare the two microphones that way even if you don’t completely understand the words.

Gain or Trim, Level or Channel Volume and Master all affect the volume of the show. I only recommend mixers that have all three controls.

Gain or Trim is used to make the performance “fit” in the mixer. Too low and it’s noisy (ffffff), too high and it causes buzzy distortion.

Level or Channel Volume is used to balance that performance with the others on the mixer.

Master is used to change all the performers together, such as fade out at the end.


It’s only when you start to run out of range on the controls do you worry about defects. Having two microphones with different sensitivity from each other is perfectly normal. Adjusting that is the job of the little Gain knobs at the top.
