Amp or speaker problem

I have 7.1 preamp/ amp combo that is losing a channel after it warms up. I'm using Infinity beta 50 speakers the amp combo is Outlaw. Prior to the Infinity speakers I was using Rectilinear III speakers. The problem happened with both brands. Originally I thought that front left channel was problem. When the channel cut off I switched to one of the rear surround channels. It worked great for about 15 hours total play time. Then same thing, so I switched agian. Worked great for about same amount of time. I've already ruled out speaker cables and interconnects, all good. I know it sounds like speaker problem, but it happened on both brands. Any ideas?

SOURCE: Stereo speaker suddenly stopped giving sound

You will need to take the speaker apart and with an ohm meter or continuity tester, measure the resistance of the speaker right at the speaker to see if the speaker is open. if it is you have no choice then to replace the speaker. If the speaker measures a low resistance, measure the wires froom the speaker to the output wires or terminals. Some speaker manufacturers install small fuses inside their speakers. Good Luck

How can i connect my subwoffer to my preamp (mark levinson 38)

You can't hook it up to your preamp. If the sub has speaker level inputs you would use them to hook it up to your amp speaker terminals. The left positive and negative goes to the corresponding left positive and negative at the amplifier and the same for the right channel.

What volume level should I set the sub at please. I have a Marantz 7005 av amp and when using Audyssey to set up, the slam from the sub is miniscule. I normally set it a 50% volume when setting up,can...

It might be easier to "skip" the subwoofer meausrement step in Audessy and tune it by ear instead. Refer to page 52 in the manual, step 6/7.

I use familiar music and test tones when I tune my sub to the mains. Generally, I set the preamp trim to -10db, the crossover as appropriate (80 or below), and then bring up the level knob on the sub to taste. Confirm phase alignment, if possible, by having someone flip the phase (if available) so the response is strongest at the main listening position.

Keep it a little "lean" at first, and over the next several hours or days, bring the preamp level up one db at a time. It takes several days of tweaking to arrive at a level that I find appropriate. Once there, I try to ignore programs with bloated bass - remember, not all recordings are created equal.

Should you fond yourself bringing the preamp level to 0 or above, kick the sub amp level knob up a couple of clicks, and back off the preamp level. It's safer to have the amp do the work, than driving too hot of a signal at the preamp level and clipping it.

Do not know how to connect my kappa 60.5cs to my pioneer cd player do they have to go through an external amp?what do i do with the power plugs on the oppisite side why are there 2 per speaker

You need to run RCA cables from the CD player to the CD or AUX input on your amp / receiver unit. If you have a standalone amp, you need some way to control the volume. Basically, if you have a volume control on the front of your amp, you're OK. If not, you should also have a preamplifier that the CD player feeds first.

From the amplifier, then, a single pair of speaker outputs feeds a single pair of inputs on your speakers. The reason for two jack sets on the speakers is for "bi-wiring" or "bi-amping", not necessary for basic stereo reproduction.

So -

CD red/white RCA out -> preamp/receiver red/white CD/AUX input. Amp speaker output (red + / black -) to one red/black input pair on the speakers. An input on the speaker is side by side...

Keep the red to red, black to black when connecting the speakers, or you will wind up with poor sound and weak bass.

`Which ampliphier is compatible for my Bose 901 series 6 with equilazer.

Ideally, an amplifier or receiver should have either a "Tape Monitor" selector switch and Tape Input & Tape Output jacks, OR have Preamp Output & Amp Input jacks to enable insertion of the Bose Active equalizer into the circuit before the amplifier stage. Power requirements - according to the 901 Series VI manual:

"Your 901 speakers are designed to work compatibly with receivers or amplifiers rated from
10 to 450 watts per channel."

If you have questions not answered by the manual, you can contact customer service at The Bose Corporation in Framingham, MASS toll free at:

I hope this helped & good luck!

It is an old speaker (DM601 S2) but well cared for. Have clear sound in one speaker and static in the other.

It sounds like a ground problem with the speaker crossover circuit or the amplifier. Turn the amp off and disconnect one speaker and interchange it with the other using the same speaker wires. If the static speaker is now working interchange the speaker wires and try it again. Or if the same speaker still has static it is the speaker. If the static is on the same channel then you have a bad wire or if both channels work it was a bad connection. If the problem remains on the same channel change the speaker wires. If the problem switched to the other channel then it is a bad speaker wire or connection. If the same speaker has the same problem it is most likely the crossover circuit in the speaker which is used to filter frequencies of the audio signal by using capacitors and coils. If the static speaker is now working and the other speaker is now not working it is the amplifier. If the static problem is on all input devices I would trouble shoot the preamp section of the amplifier.

I have just bought a new bose 901 speaker system which included equalizer. I am not sure how to connect the equalizer to my receiver Denon 3808. I need help.

Be advised, this speaker system requires its own dedicated two channels of signal preamplification and power amplification and the required Active EQ is not to be used in the signal path of anything else. I have them as my Main Left and Right Speakers in a 7.1 set-up, but I'm using a 5-channel external Carver Power Amp to drive them, a sSb and the Rear Surrounds. The Active EQ is between the Receiver's Main L&R Preamp Outputs and the two Carver Amp channels that drive the 901's. Don't think you can just add the 901's into your living room and enjoy multichannel sound. Search around fixya, I have written extensively on this subject.

Front audio channel burnout

Resistors can fail from being turned up to hire, wires getting bumped together or against metal, speakers being wrong ohms, or just plainly overheating.

Bose 802 C series II to Yamaha rxv 459 Amp

Tech data sheet with diagrams:

In a nutshell, the controller would go between a preamp Stereo OUTput and a dedicated amplifier INPUT. You can't use Bose 901 or 802 EQ in a multichannel setup without separate amps for the Bose speakers.

The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.

In a vanilla stereo configuration you would just put the controller/EQ into a Tape Monitor loop but multichannel sound and digital sources won't work that way.

You should be able to draw off the (assumed) Front L&R channel preamp signal from the MD/CD-R or DVD-R Audio Out (REC) jacks (*). Run that to the Preamp In (or whatever it's labeled on the Bose EQ/Controller). DO NOT run a return RCA pair back to the Receiver as Bose-processed signals will not play well with non-Bose speakers. (*) Run the Output of the Bose EQ/Controller to a powerful separate amp for the Bose 802/901's. I use two channels on a Carver multichannel AV-406 amp but a stand-alone Carver MT-200T also works well. A good clean 100 watts/channel should suffice at home.

* If possible, choose the recorder loop you are NOT using for something else. If you're using the MD/CD-R or DVD-R Audio OUT for a recording device just get some RCA splitters to share the Stereo signal between the Bose and the device at the same time. However, once you select monitoring of that recorder two things will likely happen - 1) you'll lose the Bose and anything digital in the receiver will be disabled.

It's the nature of the digital beast that analog monitoring gets in the way of DSP.

Of course, if anyone who reads this has a receiver with individual analog Audio Outputs for the various 5.1 channels (as I do), the solution would be to draw off the Front L&R channels to the Bose EQ and downstream amplifier and the rest would be the same but without Recorder Loop limitations.

Latest model surround receiver for bose 901 speakers VI

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).

Best amplifier for bose 901 VI speakers

By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.
