Greetings,

I am trying to install a Behringer digital snake (S16) to use with an Allen and Heath analog board. I am experiencing a hissing sound from the S16 that I cannot eliminate. At first I thought it may be due to the fact that I am using CAT5 cable that is unshielded but even when I connect the S16 directly to the mixer I still get a hiss. I have tried adjusting the gain on both the mixer and the S16 but to no avail. I have also ruled out that it was the board due to the fact that we are currently using the board with our old snake and there is no hissing. Any suggestions?

How are you connecting this?

 Analog desks in general don't have connections for digital snakes.

Leaving aside the hiss, how did actual audio sound through the snake?

It seems from your description that there is too much gain somewhere which is bringing up the noise level of the S-16. how are the mic pres set in the S-16? How are the inputs set and wired on your analog mixer?

Without more info there is no way to know for sure where the noise is coming from.

Speculation....

If you had gains on a digital snake set extremely low, and the majority of your gain after the snake on the analog desk, your signal to noise ratio from the A/D section could be very bad. For example, if your digital inputs on the snake were averaging -60, and a ton of gain was added on the A&H. The signal would be surprisingly close to the noise floor and then gained up. This would be bad. Get most of your gain from the snake.

That said... How ARE you connecting the S16 to your analog desk? I don't know much about that snake, but I am confused. It seems to be analog in, AES50 digital out.

Yeah, I can see how he would do it with multiple snakes, one on stage receiving inputs and one at FOH outputting to the console, but even then you'd only be able to get 8 channels to the board...

ADA8000 at the board side? If so, probably needs wordclock to the S16.

Hmmm... Wouldn't they need a x32 ass product to accomplish that routing?

I didn't think the ADA8000s had AES50. If not, I don't follow.

The actual audio sound is fine, comes through clear (no static) and the connection is good. I thought there was too much gain too, but even after turning the gain down on the individual channels on the S-16 there was no change. The gain on the board is no more than the usual that is used with the previous set up which has no hiss at all. I'm not sure if I completely understand how to find out the mic pres set in the S-16 (if it is the individual gain that is set on the S-16 it is -2.). The inputs that go into the board go through amps on the stage side and then through our house speakers and monitors.

Yes, I have an ADA8000 board side. It has already been synced with the S16, and we are getting sound through. Is wordclock any different?
