Sent it off to Sound Devices for service and they said it’s working properly. Were even nice enough to waive the service fee since they didn’t have to take it apart.

I guess I didn’t know what to expect when using one of these units. With my Tascam DR-100 I’d set the (I’m assuming digital) gain to Medium – anything higher gave me too much noise – and then would have to crank the gain way up in post. Never ran into any appreciable extra noise doing this, but I suppose I had the gain pretty low.

I assume there is no such thing as a pre-amp without *some* self noise. Does everyone always use a de-hiss, de-noiser or some other cleanup tool in post? I figured out how to capture a sound print of the amp noise in Audition using the hiss-reduction tool. Seems to work pretty well.

Thanks a ton, Al. That’s really helpful. Could you verify that you had your headphones at 0 db? I don’t hear any hiss at 11:00 with the headphone output at -12db.

Thanks again!

I’m simply trying to figure out if my mixer is operating properly, or if there is an undue amount of noise.

Is there a way to do that?

Thanks!

That’s good to know. Makes sense.

I guess a better worded version of my question is:

Can anyone who has experience with a MixPre-d, a Sennheiser ME66/K6 shotgun and Sony 7506 headphones confirm if you get any noise while phantom powering the mic, setting the headphone level to 0db and cranking the gain to 100% in a quiet room? Do you get that same noise at 100% gain from a recording with the unit plugged into a computer via USB?

I may be naive in expecting a pre-amp to have no noise at higher gain levels using the microphone that I’m using, but I have no frame of reference, which is why I’m asking.

Thanks again!

I get the same noise with or without a mic. I’m trying to set a baseline.

Say, for instance, is there any such thing as a pre-amp that has no noise/hiss at all when set to 100% gain?

Thanks!
