Blown Preamp?

[nate_dennis]

I pulled my 488mkii today to work on some new tracks (obviously right?) Ok, so channel one's preamp is fucked. I'm not sure if it's from the shipping or if it just died. I ran the same mic and cable through channel two with all the same settings and worked great. So I know it's the pre. Any thoughts on how to fix this? Thanks in advance.

Can you get it to do anything? Like if you crank the gain and thump the mic?

[nate_dennis]

yeah, once i got it to give me a very distorted yet thin sounding faint signal, that was it.

Anything crucial happen to it at any point?

Could be a blown capacitor, transistor or something else...or just a bad connection.

If it was me I'd be opening it up, getting out the multileter and testing for continuity from the jack to the main board. I think it is going to ential opening it up and doing something of that sort to get it resolved.

So you get the same result no matter where you route the input right?

Can you source that channel to tape and hear previously recorded material?

[nate_dennis]

i haven't tried sourcing it to tape yet. Honestly, i just kinda gave up for the day. Yeah, it's the same no matter where I try to route the signal and, conversly, I can route signal from other inputs to track one. So yeah. Since I'm new to all of this I don't have a mulitimeter or anything so I'm pretty SOL right now. I think I"m going to file a claim with the postal service (the gov't agency, not the band) since i just shipped it. Anyway. Thanks.

Three things to try:

1. See if the LINE input works on channel 1
2. Do you have an insert cable? If so, connect a line level source to the RETURN plug on the insert cable and connect to the INSERT jack on channel 1. Anything?
3. Do try sourcing channel 1 to TAPE and reproduce some pre-recorded material and see if you can get that through the channel 1 strip.
