Static noise on MOH

[tcjim]

Hello,
I have a static/buzz noise on my MOH.
Our PBX is a NEC 2000IPS and the MOH input is via the CP-24 card. The "music" is clear all the way to the phono plug connecting to the CP-24 but when the caller hears the MOH they hear the noise along with the music, which implies the card is creating the noise. This problem just started and up till now it has been working just fine. Has anyone seen this before, would this be a card failure, would a reset possibly correct this?
Thanks in advance, Jim.

Try adjusting the volume control on the front edge of the card. It may be a little dirty inside. Moving it may clear it up.

Yes, I was thinking of trying that also but thought I would check with the Pro's first.
Thanks Belevedere for the idea, I will try it this afternoon.

I tried ajusting the pot as suggested. By turning down the volume this did help as it reduced the level of the noise and it sounds OK now. I don't think it was a dirty pot as it did'nt react the way a "dirty" pot usually does.
