Amplifier problem Carver Amplifier M1.0t, Headroom Exhausted LED (yellow/amber)is flashing. And sound on the left channel is garbled.

Use speakers that will handle 85 RMS continuous or higher wattage. I have 200 watt Rockford 6.5s on a 75 watt amp. They sound great with plenty of headroom if I go to a bigger amp.

AV860 is coming up with bupkus.

Bridging instructions are usually marked on the back. Typically, move a switch and connect the pair's positives to the speaker.

suggest you look for dry joints around the faulty channel

If you can hear music with the volume up, but like it was turned down low (from the power amp), then yes there is something up with it. If it's the same on both left & right channels, then it's something common to both. For instance the power supply, or an IC that has both channels going in it.
If however the power amp does produce sound normally with another device, then either the turntable has a fault, or the pre-amp has, perhaps on the pre-amp inside it for the cartridge.

You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.

Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.

Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.

On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.

You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.

Connect the center channel speaker to the center channel speaker output on your amp.

If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.

Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.

Carver designs in general are not easy to repair. I would recommend that you send this unit into a Carver authorized service center. The likely problem is the output transistors, but the driver circuits and predrivers are not simple designs and if there is a problem there, it could effect the outputs. Tracing this will require equipment and schematics that I don't believe are available on the net.

You need an amplifier with at least 200 wpc to get the most out of your BOSE. Look into getting a NAD, ADCOM or CARVER amplifier. I prefer CARVER myself. I am running a CARVER M-500T(251 wpc) on my 901's and they sound incredible.

I can think of no reason any amp pushing 120 watts would not work with 901-VI's. They're very efficent and will probably play louder and cleaner than you would ever need. As I recall, my old series IV's have no maximum amplifier rating specified, but I did blow up a bridged Carver M-400 Cube (pushing 400 watts to one speaker with a DVD-Audio of Yes - Fragile cranked dangerously high) with them. I'm convinced my speakers are indestructible in any home application.

Keep in mind that whatever you decide to use as your control/amplifier section, a pair of 901's need a dedicated stereo amplifier. I suspect you're thinking surround sound so a receiver with separable preamp/amp channels, due to the Activbe EQ, would be needed and as far as I know they don't exist. A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver and the 901's amp channels. My receiver controls everything and just drives the Center and Surrounds.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. 120 clean watts is good. I'm using only 110W for mine.

A Carver M-200 is a fine, efficient amplifier that would have you cooking just fine (2x100W).

your going to need this place to download the remedy's for your system http://www.euras.com/repair_tips_1/CARVER/AV505/AV505_CARVER.htm

if it is not working then there is another serious problem , and it could be the amp IC or the volume IC but tests will need to be done to determine what is causing the failure , but it does sound like amp IC as a suspect since the rear were not even working , did the volume seem different when turning it up or down before the center quit or after the center quit?

possible short in speaker system. Disconnect the speaker to that channel. if it does not click off then you have a short outside the amp in your wiring or in the speaker.
