Ok,
I am using a tube mic for the first time. Question, Do I still use phantom power on my micpre or do I turn it off. Im asking because I have hooked the mic up to the power supply after I turned off the phantom and I am getting a input signal on the micpre even with phantom still off.

So micpre phantom or not?

The mic has no instructions that pertains to this.


Thanks

Malcolm
 
Either way is OK, but better with it off - less chance of hum or other spurious interference (in my limited experience.) The tube mic has its own power supply and doesn't need the phantom.
 
Ditto, the V69's power supply provides phantom power...no need for it form your pre. However, I have alternated the phantom power with the V69 on and off. IMO, the V69 sounds best with my Sebatron pre with the pre's phantom power on. It sounds a bit fuller. However, it's certainly not necessary.

Ok,

So your saying I can turn the power supply off, then turn on the phantom on one of my other pres and it still works? I dont which would be better. I guess I would have to listen. But the 2 pres I will try would be my internal DM24 pre and the SP VTB-1.

Malcolm,

This question actually not that dumb. I remember, once on RO forum Stephen Paul and Jacob Earland literally got into a fight on the topic (it was about ribbon mics) and never got to concensus. With V69 you can turn phantom power on (which BTW won't do anything there). As I mentioned in another thread, this mic is a hybrid design and I am sure there are blocking caps in the outputs--they just ought to be there. These caps won't let any DC to get in or out of the mic--you are safe.

How much of an effect are you noticing? It seems like this shouldn't have any effect at all on the sound.

Thanks Marik, I guess it was more of a cautious question. Just had to make sure. It doesnt bother me one bit to ask questions in here because thats what the forum is supposed to be about.

If I ask a question its because I am planning on doing something or investigating how to approach or what to maybe expect from proceeding.

Thanks

Marik ( with his limited post count ) gets Merit from me. LOL
cant judge a book by his post count.
:D

No. I'm saying that I turned both the v69's power supply AND the phantom power from the mic pre. In that case, I noticed a subtle by tangible difference. I'm not an electronics expert. My only explanation is that perhaps the mic is slightly underpowered by its own power supply and the additional phantom power is helping it to be all that it can be...or it may be nothing at all.

It's a subtle difference/effect. Something that I can notice with good headphones and not necessarily over the monitors. See my previous comment to malcolm 1 post above as to my guess as to what's happening.
 
malcom, what do you think about that V69 so far? i'm in the market for a ~$250 primarily vocal mic, and i'm debating between the V69 (or V77), a shure SM7 and an AT4040.

yes, i realise they're all completely apples, oranges and bananas in relation to each other. i've already got a good dynamic (RE38), so i'm thinking that i'm gonna pass on the SM7 for now and look for something in a LDC. the V69 and V77 have gotten plenty of good reviews, just a matter of figuring out which one. :D

I havent really got the chance to start tracking with it yet. I have been mostly messing with my new board and setting gains, levels and stuff. From what I do see, I unplugged my V67g and put up the V69 and wired it up. I did a few check 1s and check 2s. The first thing I did notice is that I had to back off of it some. So I pulled the pop filter back . Also had to decreas the trim and inputs and outputs of the micpre. Then I hit it hard with a hot vocal level to see how it distorts. It held up pretty good with the new pop filter distance. Im tracking vox tonight and once I get them to hard disk and play them back through the mixer I will be able to tell you more.

It looks good , its longer than my V67g, seems to sound better, but i cant really tell right now. Im probaly gonna change the tube in it leter on down the line.

Hey, Rev, it probably is nothing at all. The mic pre's phantom power won't come through to the mic. The mic's power supply has some device (probably coupling caps) that block its voltage from the mic pre. The same caps block the pre's voltage from coming through to the mic. If there is indeed a difference to be heard, it probably comes from the phantom power putting a bias voltage on the preamp's coupling caps, which are usually normal electrolytics. Electrolytics may perform better with a bias voltage.

BTW: A tube mic's power supply usually supplies much higher voltages than normal 48V phantom power.
