hd channals turning my amp off

superjunior

Just got done hooking up my new xpa-3, and as advised in a different thread, I'll have everything on its own circuit soon. Got all wires ran, ziptied and signal and power cables seperated. Everything looks and sounds perfect -BUT-as I was flipping through channals, as soon as I got to the hd channals the amp cut off. The standby (power) button flashes as well as the small red light on the left of the panal (left channal indicator).When I shut the amp down and powered it back up again, the hd channals work just fine, but if I go back to reg. channals, it shuts down again. I double and tripple checked all my connections and everything seems to be in order. Strangest thing, as soon as the channals go from standard to hd (or vise versa) it shuts the amp down. Anyone have any ideas? Thanks

I don't know what's going on there. Are you running the cable of Sat/box through the Pioneer into the TV using HDMI! If you are try running the BOX directly to the HDTV and using the digital out from your HD Box to the Pioneer and see if the same thing occurs? As an experiment.

As I have it configured right now, I've got cable from outside going through power center (filter) and ran to cable box. I ran componant and optical from my hd box to my avr -did so for better upscaling results- than an hdmi to the tv from avr. I also have a sepperate hdmi from the cable box dirrectly to the tv, as to watch tv with audio gear off, but that shouldn't effect the problem at hand. this is a tricky one...

Run the HDMI from the cable box to your AVR, Then run your other HDMI cable to from the AVR to your TV. you don't need the Component cable or the optical cable.

My guess is this is your problem.

You will get better upscaling with the HDMI cable.

will start a new thread on this topic, pm'd you Larry

btw, I do have a blown left rear speaker, but it's hooked up to the reciever, not the amp

Running two video and audio signals from one source to the same tv endpoint. I have never heard that done before. I use hdmi from cable to TV (pre doesn't support hdmi input) and opitical to preamp for surround processing. Therefore, tv still gets audio through hdmi if that is what you are looking for.

I don't know if I should start a new thread on this topic or what, but since its best to know how I have everything hooked up to evaluate this, I should probably explain why I have things hooked up this way. From what I understand, my avr should do a better job at upscaling than my tv. Hdmi is the way to go these days, I know. But from what I've been reading (and correct me if I'm wrong) you can't upconvert with hdmi? It only passes the signal through. So my tv would be doing the scaling instead of the avr. By running the componant and optical from the box to the avr, the avr should be doing the upscaling than going to the tv via hdmi. This is something I read on a thread from avs sometime back, and again, anyone can chime in here and any advice is much appreciated. I've used this set up for a few months and everything has been perfect, even standard def looks really good. I also have an hdmi cable from the 1 hdmi output from the box to the tv, to watch cable without the audio gear. For some reason toggling from st to hd shuts the amp down. Re-wiring things does take a little time, but I'm open to any ideas.Thanks tool and cnh, I will give those suggestions a try

I just change input selects on the tv, the signals aren't run at the same time

Update- problem is not just the cable box. It seems that changing advanced audio settings and input selects on the receiver also shuts the amp down. When listening to music or just watching tv, the amp is fine, but when any changes are made(going from st to hd, changing audio settings, ect.) it shuts the amp down. I'm using cheap monster ICs, I'll start there and see what happens. I'll have to order another hdmi cable. Not paying full price from somewhere like best buy. Any other thoughts before I start rewiring everything? thanks

Sounds like some kind of a spike. If you are using the 12v trigger to the amp, disconnect that and see what happens. If it still does it, then it is not there. Then I would check the set up on the AVR. Looks like you only have front mains connected right now, make sure the AVR is configured correctly for front L & R only. If everything is ok then remove the L ch. IC see if that flashing left ch LED is telling you something. If it still does it remove the left ch. speaker wires at the amp side. Just guessing but worth a try at trying to isolate the trouble spot, AVR - amp - wiring. Only other suggestions I can think of would be the Emo forum..... and do not do your cable management until everything is up and running;) also skip the zip ties and use something else.

not using a 12volt trigger at this time. I'm running rtia9's in the front, a center and 2 rear surrounds from a cheap rca setup. 1 rear was blown and I just replaced it with another cheapy, that didn't change anything(didn't think it would) The avr settings are LARGE for the fronts and small for the others. I'll try your suggestions with the left ic and speaker wire. this is most frustrating

O.K, I just unplugged the left ic and plugged it back in and bingo! everything works ok.That seemed to have cured most of the symtoms but the amp still shuts off when I turn off the avr or cable box. If I just turn the amp off first than everything is fine. Wondering if this is because everything is on the same circuit? Also on hd channals, one front seems to be a little louder than the other, and on st. channals the opposite happens. I hope maybe its the cables and not something with my outs on the avr or a bad channal in the amp. Maybe I'll try a different wiring configuration with the cable box and avr as others have suggested, but the problem seems to stem from the left channal as the red channal light on the amp goes on when the amp shuts off.

Not familiar with the XP's, but I know on the LPA1 on power up the amp runs a quick test then the amps become active. I think this circuit will shut down the amp anytime it senses a problem. It sounds like the L ch. of the amp is seeing a problem and shutting it down. Either it is a real problem with the input, (bad IC or originating in the Pioneer) or a problem with the amp. Have you swapped the L ch IC with one of the other ch.? Plugged the R ch output from the Pioneer into the amp you have the L ch. plugged into? Talked to Emo?

I will try using a different wire on that side, or swapping it with another wire from the right and see what that does. Man I hope its not a problem with the avr or the amp.

superjr,
Isn't this metal's XPA? Since he had no issues like this, unless it got damaged in shipment, I think you can probably rule out the amp. IIR the Emo warranty transfers (not sure) so if it should be the amp you would have that going for you.

On the other hand metal did have a strange single ch problem with his XPA5 hooked up to a Pioneer. What model Pioneer are you using? Probably nothing, but sometimes different gear just don't play well together.:mad: Keep us posted with what you're finding and good luck

yeah it's metals amp. He packed it extremelly well, I really don't think its the amp. I've got the pio vsx 92txh, the older version of the sc-05 I beleive. Got rained out today here in the sunny shores of ne ohio, so I'll have some time to do some testing today with the wife at work. Lesson learned about cable management what would you suggest instead of zipties? I do love my zipties

superjunior

problem solved! I replaced the left ic with another cheap monster cable I had lying around, that was it! Seems the xpa is a bit picky on the wires used. I'll be replacing these with good quality ics. Everything looks and sounds perfect. nothing I do now turns the the amp off- besides powering it off correctly- no more flassing red lights, nothing but peace and harmony. Thanks to all you helpful folks for helping me solve this problem. Btw apphd, still curious what to use instead of my zip ties

There is no guarantee that a "good quality" cable will work. Unless you know exactly what is that the EMU doesn't like about some IC's, I wouldn't go spending good money in new cables.

Congrats time to enjoy.
These are what I would use over tie wraps for the fact they are easy to remove and re-use, and small triwraps over tightened have potential of causing some damage with some cables.

Also avail. in bulk rolls. There are other options as well.

SJ i use Audioquest with my Pioneer and XPA-3 with no problems, I have also used MIT with no problems as well. There is some Audioquest Diamond Backs in the Flee Market for a very good price if you can swing it, I would jump on them.

Glad your issue is solved. Good talking to you on the phone as well.

Larry.
