M470A phantom power issue.

Yeah, I absolutely love my tube coffee maker. It's noticeably warmer and more full than solid state. But then, I also wouldn't be without my analog toaster.

Best,

I love my solid state lawnboy lawnmower...

hey guys!

i didn't bother opening a new thread for this, cos it's just a quick question.....



can i just unwire one of my aux pots on an m470a and use it for an output gain control?

i know it's not the 'right' kind of pot, but it'd be ok right??


the reason i ask is, my preamps are SWEET but if i use the pad, i can hear a slight buzzing..

i do have the fader simulating resistors wired in, but they're still far too hot to use on overheads for example and an output gain would go a long way....

also, don't have room on my face plate for more knobs as you can see,


i wired echo send on the auditronics modules as output gain control and it worked a charm!
i get the feeling they sound better driving quite hard with the output gain turned down, but i wanted to check with the pros about the m470a first..

you can use an Aux, but I would use the Right output and use the pas knob instead.  either will work. but the Pan uses dual elements (so +ve and -ve have their own contact) where the aux have a single one

as well, there should be a 15db pad in place where the fader goes, not just a jumper.  

looks nice btw

I'm not a fan of XLRs on the front... I'd put the line / DI in on the front... "but that's, like, my opinion man"

[steenamaroo]

thanks for that!

i have to be honest with you, i'm not a fan of front xlrs either, but i only have a small setup and it's more convenient this way, for now.

ok, so, regarding the fader, i wired up 240 ohm resistors as per a guide on this forum..

pan knob sounds like a plan!! i like that.

i'm currently wired to p2c and p23 for direct out,
but 'm lookin at the scematics, and it seems like you'd wire master 2 output for right?
is that correct?

also, is there i difference in impedance? or is it just gona be the same as direct out?

thanks again.

[Anthony P. K.]

you are correct to come out of M2

R112 and R113 would need to change from 15K to 75  as it's meant to go to a summing buss

have fun.  and remember, if it sounds good it is good

[steenamaroo]

ok,thanks very much for info. i can't tell you how much i appreciate it...


you know. i bought these preamps for £45 each cos i wanted somethin to solder/mess with/learn from...

absolutely astounded by the sound of them!

and so far, they've managed to have better customer support than most current/big firms! lol.

cheers.

[Anthony P. K.]

thanks man, that means a lot. 

be well

[steenamaroo]

stupid question perhaps, but is it 75ohm or 75kohm?

thanks again.


**edit. if i'd just looked at the schamatic instead of thinkin out loud, i wouldn't have had to ask! sorry!
