anyone managed to get dual amp to work while in 5.1 mode?

 

i have disabled the surround back speakers and have biwired turned on. Speakers are wired in biwire config. dualamp and biwire lights turn on when in 2 ch mode. But the moment 5.1 kicks in, the dualamp/biwire turns off.

 

There was a thread in avsforum where somebody claimed that dual amp still works in 5.1.... (becoz still have leftover amps from surround back channels) Dunno if its wrong info or not.

 

Anyone got it to work?

 

manual says only stereo mode, no?

Hiya guys,

 

Have done it for a friend on stereo like Sirius says, don't know about 5.1 thou....

I'm using for bi-amping also. For stereo, both lights are on.

Think when I switch to 5.1, only 1 light will go off, just not sure which is it.

Will try tonight to refresh my memory.

i think biwire will be on and dual amp off cos the amp needs to drive the rear speakers.

For me, with stereo sources, I will get both light on.

 

But the moment i switch to  5.1 source, both lights goes off.

 

There has been some confusing info on avsforums, so thats why i want to find out if someone managed to get at least dual amp working on 5.1 sources.

 

My magnepans needs serious juice. Need every amp that I can bring online. :)

Hmm.. tested last night just by pressing prologic button. Seems like mine also got both lights off.

But sound is ok, so assume bi-wire is working (2 amps).

 

Maybe that's just the way the lights work.

Yeah, mine works that way too.

 

I'm just being anal. But if both lights are off, it means that only one amp is driving both HF and LF of the speaker.

 

dual amp LED on  = HF 1amp, LF 1 amp

dual amp + biwire  LEDs on = HF 1amp, LF 2amps

 

 

According to the XR55 Manual Pg.15 under the header "Enjoying BI-AMP Sound", it states that BI-AMP only works when input is analogue (excluding DVD 6-Ch) or a 2-channel PCM signal.

 

So I guess that's the reason why the BI-AMP light is also off when the amp is in digital surround mode.

Dunno how that works.

Since it's tied to 2 binding posts, I thought that it should be a given that it's running on 2 amps at all times?

Only when stereo can they channel 1 more amp to bi-amp.

this was the main issue that i was pondering on when i was reading the XR55 manual before buying it lol...but it sounds correct so i just --- stop wondering and enjoy the music!

in stereo mode only

if you use single wire - its using 2 ampos (Dual Amp)

if you bi-wire it's using 3 amps

 

check out the FAQ area

 

I was just playing a dvd, and god knows why, 'dual amp' light up only, but it is stereo only I think (special features).

Wonder why it triggered this mode.

probably because you don't have PLIIx turned on permanently on the DVD input. also it seems the relays are auto sensing, so if you have a stereo signal it'll auto switch

Yes, but theoretically if it switches to stereo, it will light both lights because I'm bi-amped.

But there's times when it only switches on the 'dual amp' light.

its that relay no one knows about (how it works, what it is exactly etc etc) heheh
