control4 c4-amp108 no global IN

[ultrastvrr]

Hello guys!

 

New user here; I recently acquired a used control4 c4-amp108 and I am trying to get this setup,

however for some reason I am unable to get the global line IN to work. All the zones work fine except the global in.

No audio output when I connect anything to the Global IN and out to any of the zones.

Also, when switching the mode from "line" to "global" in any of the zones, should the audio be cutting off?

right now swithing it doesnt do anything.

Did I get a defective unit?

Tried looking at the online manual but it did not help.

 

Any help would be greatly appreciated!

 

thanks!

If you have the dip switch set to global, the inputs at that zone itself will be cut off, and that zone would use the global line in.  I'd verify you have music coming into that input, and also make sure your gain on the global input isn't turned way down.

Thank you for the reply.

 

I've did some more research,

for the global output to work, do I need to have the phoenix connectors in? not sure if thats what you were referring to when saying dip switch (or just the lil switch you move left to right)

I have no phoenix connectors with my device.

Im new to this so apologies if Im asking some super basic questions! 

 

Note:

When I connect my audio source to GLOBAL IN and output to GLOBAL OUT, it works fine, audio is ok

When I move the GLOBAL OUT audio cables over to say Zone 6's Line OUTPUT, and move the lil switch from line to global, nothing happens.

Also, if I have line input in say zone 5 and line output on zone 5, it works fine. if i move the switch over from line to global nothing happens (audio doesnt cut out).

Is this normal?

 

Thanks again

Hmm. While  would expect it to still output, you do NOT need to feed global in to a zone, that is only if you want to loop the global out to another zone's global in.

 

I haven't tried this, but I wonder if when using global in, it will not work with audio sensing - so you will either have to control the amp on via relay or force it to always on (I really don't recommend that, except to try if you get audio). For that though, you WILL need the phoenix connectors.

 

Oh and by dip switch he means the little switch that goes between global and line in (though not the one that does bridging!)

Thank you for your reply and sorry for the late follow up.

 

I'll try messing around with it when I have more time.

Is there any downloadable manual online by any chance?

I only found the data sheet brochure but thats about it (https://www.control4.com/docs/product/4-zone-power-amplifier/data-sheet/english/latest/4-zone-power-amplifier-data-sheet-rev-b.pdf) 

 

Thanks!
