I got my XPA-2s. Do I leave these things on all the time like my former Odyssey and Class D amps?

Thanks,

Mike

    Well right now I'm Central. Does that change if I go Eastern or does the amp just know?

    Well, Indiana moved to Eastern Standard Time one or two years ago. Maybe if you adjust your watches everythig will start sounding better.

    Yep, the amp just knows...the internal GPS lets it know exactly where it is...wait a minute...it has to be on for the GPS to work....hmmmmm....I'm gonna have to think about this and get back to ya.

    It seems there is a standby mode but I'm not certain how that works. Do I hit the button on the front? Is it auto like a subwoofer? Should I keep it full powered anyway?

    It uses 90watts at idle or 4 watts in standby. Your not going to tell a difference sonicaly so you should just turn it to standby when not in use & save some $ on your bill, thats what I do with my lpa-1 & its fine.

    Yep, me, too. Turn it to standby.

    So what's your initial impression of the amp?

    SolidSqual, asks on Emotiva's lounge. That's where I would ask.

    I can't do that! Certain people might think that I've left the forum because I'm sick of the so called mob mentality.

    Heh, we already gave you the right answer. Put it in standby mode when not in use, thats what its there for. If you are worried about the affects of turning on & off your equipment too many times, I believe you would be well rid of that amp & trying something else by the time that issue has an effect. Its an awesome amp & Im only saying that cause people in this hobby like to try new equipment every few years.

    Any idea how long it takes for the amp to warm up each session? That's my real concern.

    Do some listening tests with it being "cold" vs powered on for an hour. If most of its use is watching movies then I really doubt one could notice a difference. I may be wrong but I would assume with 200+ watts going into it while playing sound that it would be pretty warm even after 10mins, but thats just a guess. Chances are there are other things in our systems that could be improved with greater benefits whether its equipment, placement, or accoustics rather than worring too much about the small difference between a "cold" amp vs. a warmed up one. If it was a tube amp or high end Krell or Levinson then it might be different.

    It depends on how hard they are being driven but with a Class A or Class A/B design the bias should stabilize in the first 30-60 minutes.Class D like the ICE Power and Hypex modules should see no change whether left on or off as they have no standing bias current that needs stabilizing.Ironically the are the ones that consume less power if left on.

    My amps are always in standby unless there is a thunderstorm. Even still, it takes at least 30 minutes for them to come on line and sound the best.

    90 watts idle, would that mean a dash of bias into 'A'? I like the sound of that. My GFA-5500 idles around 190watts and I think it reaches equilibrium within an hour and my GFA 585 was more around two and it spec'd an idle of 90 watts til it burped up a cookie a few days ago.

    Early and SolidSqual ya beautiful bastages :) all this XPA-2 talk got me going...my soon to be left Nashville this morning. I'll live through you guys til mines in place.

    I love this place and I like the Polk-Folk.
