Hi,

These are Creative Z5500 speakers and you have an audio control panel that allows digital in or analog in, correct?

Digital out is usually marked by a black color ring not green and would have a stamp on it indicating digital or spdif. Digital out and coaxial out are the same thing and are a simple mono male to male mini 1/8 twisted copper cable.

You can use the digital in at the desktop control unit with a mono mini 1/8 male and male cable available at any Radio Shack and also get a mono RCA (any color) male to male adapter. Just explain your needs to the clerk there and they'll set you up.

An optical connection is completely different and makes no difference. The jack is square and usually has a plug in it to keep dust out with a square knob for grabbing it to withdraw the dust plug and put it back in place again. It's best not to bother with these things as they haven't found a place in the market.

Just so you know, you can use the analog out on your laptop to the analog in on the control unit and then select Dolby digital for processing and you won't know the difference. This whole digital thing is blown way out of proportion unless you're working with HD out to HD in on a flat panel TV unit from a Satellite Receiver or Cable Box.

Any other questions just ask away and please don't forget to rate our solutions on FixYa. Thanks.

I suspect one of the upfront IC amps has been damaged. This can happen if people power the mixer from a receptacle that is different from where other connected equipment is powered such as amp. For example, mixer is at one end of the hall and other inouts such as an output of a guitar amp is plugged in. If a ground fault or spike occurs, teh ground bounce can exceed the common mode voltage of the input amps.

In your case, the inpout amps are discrete transistor types.

A voltage surge into the inputs of your unit would LIKELY pop two bypass caps that are 330pf. For channel 2 these are C205 and C206. Check those for shorts.

VERIFY audio is available at the "send" (tip) of the channel insert connector... this verifies the preamp stage. You can PROBABLY plug a set of headphones in to check this... ONLY one side will have sound of course. Verify this is a good test by checking a working channel. The level will be quite low and we are looking for just some signal.

IF you do have signal on the channel insert send which is the "tip" of the channel insert with the trim turned up, let me know and I will check the schematic for the next thing to check farther down the line.

If you plugged into stereo channel 9/10 that is an input channel... That will not work...

you need to connect to a stereo OUTPUT.

If you have a "tape out" set of connectors try that... or a main L and R output.

You're just not the first with that problem.
Everybody everywhere, also Acer, seems to be very quiet about it...

Are you getting signal into the mixer? Do the level meters light up?

If so, check your speaker cables. If not, check the mic cables and mics (try with phantom power on and off).

Also, try plugging a speaker into an Aux out to see if you can get level out of that.

Hope that helps...
