Surely this is a bad idea since 1/8" line-in (shared with mic/in) jack on the laptop is fiddly.

But, I don't have a leeway to use a USB or firewire interface in my situation.

So... have to use the laptop's existing internal card and jack.

Is there a way to somehow reinforce the mini jack, to make it less prone to bad contact/crackling?

My signal source is the output of Mackie 402 VLZ3 mixer.

Thanks!

Couldn't tell you, but I have heard from local sound guys that if an input isn't an XLR or 1/4" input, it's probably "consumer" line level as opposed to real line level (I think consumer line level is -10, while "real" line level is +4, or some such. The point is, consumer is way more sensitive, TOO sensitive for a real line level signal). The XL2 camera suffers from this, as does my Imac. This is not to say you can't use line level devices, but you have to attenuate their output to prevent distortion.

As Josh said ... the laptop's input will be -10dBv consumer level while the Mackie main output will be +4dBu. The "crackling" may well be clipping rather than a poor mechanical connection. Take your signal from the Mackie's "tape out" RCA jacks as they will also be consumer level and see if it alleviates the problem.

Thanks.

Steve, in the meantime I read your posts on the subject, and got warmed up to 1/8" adapter.

But with a twist.

I'm getting a PCMCIA interface card Indigo IO, and will feed Tape out from Mackie into it using RCA to 1/8" adapter.

Should work, I think. Indigo's specs are great, should be much better than laptop's.

Thanks.

I agree - I have both an AudioFire 12 and and an AudioFire 8 and I am quite pleased with Echo's products. While I haven't used one I would expect the Indigo to be equally as good.

Mackie tape out RCA connectors are usually higher in output than -10db. If I remember correctly from the past, around 0db. So you should still listen for clipping if you're connected to a sensitive input.

Still listen ... absolutely! But my Mackie lists the tape outs as being consumer line level. OVU on the meter is 0dBu on the main outs, true, but the tapes are spec'ed at the lower line level.
