Carver Sound Problems

I have a 1996 Carver CT26v Preamplifier & AV505 5-channel power amplifier. Everything worked fine for 2 front speakers on channels 1 & 3, until I added a center speaker on channel 3 & two rear speakers on channels 4 & 5. The rear speakers never worked, the center speaker quit after 2 hours, & eventually the front speakers quit too. I followed the manuals installation instructions & schematic diagrams, checked everything 3 times. Have you solved this problem before; apparently it is a common problem(sounds like dud channels &/or thermal issues).

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?

Best amps for bose 901


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.

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.

http://hdtvdreams.com/Adcom-GTP-870HD-7.1-Multi-Channel-Processor/Preamplifier-GTP870HD.aspx

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.

How to hook up bose series 2 eq to onkyo tx sr 875 receiver.?


I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want to do and it works great! I see on the SR875 there are Pre Audio OUTS. This is easy.

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 Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.


Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Connecting Bose 901 series iv to Harman Kardon AVR 254


Most HK av receivers have pre amp out,power amp in with metal jumpers connecting them for the main or front channels. that would be the best place to hook up the EQ on a AV receiver. If your receiver doesn't have pre out, power in jacks , you can use tape monitor .record out playback in. The tape monitor option is best for stereo use , as the active EQ will charge all speakers in tape mode, possibly damaging other speakers.I run my 901 s with a seperate pre-amp,power-amp hooked up to my Denon AV receiver that way i can run in surround w/standard speakers

Looking for a good amplifier


Any 2-channel (or greater) receiver or integrated amp with at least one Tape Monitor loop; or any separate amplifier - will work. I would look fror one with true > 100 watts per channel, all channels driven, 20-20000kz + a few dB, with less than 0.5% Total Harmonic Distortion (in other words clean and powerful) should suffice. Specific brands don't matter. I'm partial to old Carver amps.

-----

However, should you get a multi-channel amp for the 901's you will be limited to using only 901's on it as the required Active Equalizer would affect all speakers attached to the amp, and conventional speakers would not sound right and could possibly be harmed by it's drastically-altered frequency response. Since using the Tape Monitor on modern DSP Receivers disables their digital inputs, that would limit what you could listen to, should you later decide to go with Cable Box, DVD, SACD, DVD-Audio, Blu-Ray, DTS etc.

* There are no some multichannel receivers out there that allow separating the preamp-amp circuitry for each channel to allow for differences in speaker processing. I think Marantz had one.

However, having a 901-based multichannel setup myself, I would highly recommend getting the Full Monte for video listening (below)...

In that case a separate stereo amp for the 901's would work. 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 Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.


Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

---------

So to sum it up, I think you should start with a powerful, clean amp with few bells and whistles for the 901's and maybe later add a multichannel receiver with all the magicfor source control, DSP and to drive the other channels.

How do I connect my bose 901 active equalizer to a onkyo tx-sr506


AV receivers are notoriously incompatable for Bose 901s. The problem is the EQ charges the entire system and could damage the surround processor. Some higher end AV receivers, including some of the newer Onkyo models have pre out power in inputs on main or all seven channels.which you could install your EQ directly between pre amp & power amp without damaging processor. You can also add a two-channel amplifier to the pre out jacks front channels and use your recever's remote to control volume.
