Tube mic wiring... can't find pinout for Avant CV-12

[romanarlovski]

Can anyone help me find this, or does anyone have this?

Sorry, to be more specific I'm looking to make a 7 pin XLR cable for it.
As an example for another manufacturer with Mogami wire:
1. 200v (constant side of bias) Red
2. 6v  (heater) Green
3. 0-200v (bias) Purple
4. signal ground (balanced pin 1  [on psu's 3 pin xlr output]) Ground
5. - signal (balanced pin 3) White
6. + signal (balanced pin 2) Orange
7. ground (centre pin of the 7pin connector) Ground

on Avantone PSU PS-12 (delivered with Avantone CV-12 microphone) 7-pin XLR is:

pin 1 bias 1 (constant)
pin 2 bias 2 (from characteristic selector)
pin 3 heater 6V
pins 4 & 7 (and body of XLR) are connected to chasis
pin 5 signal cold
pin 6 signal hot

I hope this helps
regards, Ivica

FWIW  IMO better off using gotham tube mic cable.

So 4 and 7 are both ground, and connected to chassis?

 

[elektroivo]

connection to chasis is made thru body of XLR, and there is one wire that goes to PCB ground from pins 4 & 7.

i'd send you a photo, but I've returned mike this evening.

It had some issues in capsule circuit, and had making noise like "cooking" for about half hour. after that worked silent.

it was problem in assembly...

annyhow, this microphone works really great, especially for that price... I'm still schocked haw good it is

Hi, I'm trying to put this cable together tonight, and I got a reply from Glen at AVANTONE, indicating the pinout is actually different to the above scheme, specifically 2 & 3 are reversed.

Can anyone confirm having tried this?

I don't wanna do this the wrong way and fry anything, least not myself!

From GLEN at AVANTONE:

The actual signal pinout is:

1                    150V
2                    Heater 5v
3                    Capsule pattern bias
4                    Ground
5                    Output+
6                    Output-
7                    Ground

Best,  Glen Heffner

Oh, and you can see he's indicated pos and neg the other way around, too.

Thanks,

The only way to be sure is to take out your multimeter and check.
