Can you bridge channel b on the isignia r2001 receiver


No. It has only two amplifier channels and the speaker A and B terminals just share physical access to them for two pairs of speakers. It's not four amps.

SURROUND AND CENTER SPEAKERS WORK FINE BUT NO SOUND COMING FROM FRONT SPEAKERS. WHAT COULD BE THE PROBLEM?


Can you fill in something about the speakers and how you have them attached? Since this is a stereo amplifier one wonders how you have anything but the front speakers powered unless you're using THIS amp for just the one pair and driving it from an AV receiver pre-out.

I have an Onkyo A-7055 amd want to hook up two speakers. Looks like a dozen connectors in the back of the unit... which ones to use. If I experiment is there a chance I could blow out the unit?


Do you mean you want to connect 2 pairs of speakers, or just 2 speakers like you say in your question? There are 4 pairs of screws on the back of your amplifier on the upper right side of the rear panel near the fuse cap and the AC outlets. Each pair of screws will be connected to one speaker. Your Onkyo can be connected to 4 speakers. If you want to connect only 2 speakers, use the screws labeled "SPEAKER A" and connect the speakers to the left and right channels, and make sure you connect the + speaker wire to the screw with the red marking around it. Connect your other speakers the same way, one speaker per pair of screws.

Mute function on the amp


A couple of questions to try and narrow this down:

1) What is the impedence rating for the speakers?

2) When the unit shuts down, will it recover on its own after a little while or do you need to power cycle it to get it to work again?

3) When the unit shuts down, is it hot?

Possible causes of this behavior:

1) Impedence rating too low causing the amp to work too hard and shutdown.

2) Excessive heat (caused by #1?) will shutdown the unit to prevent damage.

3) Possible intermittant short in the speaker wires somewhere? Loose connection?

A little more investigation will be required to find this. A repair shop would run this unit under load and monitor the outputs for heat and any spikes in the signal that could kick in the protection circuits.

Keep us posted on what you find.

No sound to remote speakers in dining & deck areas.


Incoming from WHAT? Ampifiers accept inputs via RCA connections and send amplified audio to the speakers via the + and - OUTPUT terminals.

I'm guessing your colored wires are from your speakers and that there is a piece of this puzzle we do not see - how the speakers on the deck and in the dining area are wired.

You say, "was working ok previously"... previous to WHAT? Something changed.

You can probably troubleshoot and resolve this yourself.

Set the amp to a medium output level.

If the wires are simply leading to either or both pairs of speakers you could select any two of them and connect them to one side of the amp. Only a pair going to the same speaker(s) will produce sound. Once you identify one pair, the other pair probably goes to the other speakers. Connect them to the other channel output.

The last piece would be to establish correct phasing between the speakers. Bass response will suffer if they're not IN-phase. Play something with substantial bass. Listen closely, then reverse the wires on one side only. Test again. If it IMPROVES you have it right. If it losses bass, put the wires back the way they were.

CROWN CE1000- slips into fault immediately after connection


if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed

Purchased 2 used sonance sonamp 260 for homewide speaker system (12 pair).line out from receiver into first amp powering first 8 pair.line out from first amp into second amp powers remaining 4pair.only...


I am assuming you are using the standard sonamp 260 not a 260x3
and that when you say you are getting sound on only 1 pair that means only on 1 side (left or right channel only?)

Are using a speaker selector box? you must to regulate the resistance (ohms)

if so first unhook all but on pair of speakers and see if both channels are working.

if they do your problem is in the speaker selector not the amp if no then check to see what the amp level is set to. These are the two small holes on the front right of amp make sure they are set about equal at around half way up.

If that doesn't work flip the RCA cables coming to the amp perhaps you have a bad cable if that doesn't work make sure your receiver (source) is outputing a stereo signal to begin with.

lastly 8 sets of speakers off 1 amp? that's pushing it.even with a high quality Niles or speakercraft selector that controls the resistance going to an amp I wouldn't go past 5 sets.

The right way to do it would be to use 260x3 or a sonance or speakercraft 12 channel amp.

Carver Sound Problems


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?
