Hey guys,

It's been a while since my last post here but I was hoping I could get some advice on an issue I've been having. Im currently running my pod HD 500 into my focusrite 18i20 via the 1/4" outputs and there is an audible hiss in the signal. I can see in the spectrometer that it is strongest at 10K but has harmonics around 5k and 2.5.

Is anyone else experiencing this? Is there a solution? I don't really want to notch those frequencies out every time I want to track. I think I remember Johnny talking about this years ago but I could be mistaken. Any help is appreciated.

Thanks!

do you also have this problem when you use the Pod as interface itself or only when you plug it to the interface? if it´s the latter, i suspect it´s extra noise coming in through the cable conection and the pre amps and converters in the interface. i wouldn´t recommend using the line outputs going into line inputs again on the interface. basically what you got there are two AD/DA conversions, one in the Pod and another in the interface. and with that come extra pre amps and connections that can make more noise. the fewer conversions the better. i think your interface has spdif, right? i have the Scarlett 6i6 and that one has spdif. i´d use that instead. then the Pod is doing the AD conversion and the interface is doing the DA conversion. so between the two devices the signal stays digital and therefor you won´t get any more noise or quality loss. it stays clean.

That makes sense, I remember in your tutorials that you were using the s/pdif connection instead of 1/4" cable out. I'll give that a try tonight and hopefully this will diminish the noise if not eliminate it all together.

Thanks again!

So I've tried using spdif as opposed to the line outs on the pod and the hissing problem is no longer an issue! Although a new problem has arisen which I again can't seem to figure out on my own. Now that the pod is connected via spdif cable to the interface, there is an audible click in the signal which I assume could be the word clock. It always continues at a steady pace and only while the guitar is playing (perhaps because I have a nice gate in the signal chain). I'm not sure where to start with this one
