How to connect bose acoustimass 15 speakers to Onkyo TX-SR705 7.1 Channels Receiver

Do you have the interface cables for the Onkyo? And is this simply a DVD connection. Nothing else planned for this connection? I have two installation guides for Onkyo outputs.

You will need to connect the speakers to the front channels as you would with any normal set(Speaker + to amp +, speaker - to amp -, etc) then you connect the special Bose equalizer through a tape monitor loop and always have the monitor loop engaged.

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

NOOOOOOOOOOOOO!!! If you have the room for them to run free and loud, keep the 901's in service. Get them a good amplifier because any multichannel receiver can't deal with their special EQ needs and still drive conventional speakers for the other channels properly.

The good news. I have a setup similar to what I think you're trying to do and it works great! Get a receiver that has has 5.1 analog Outputs so you could drive up to 6 external amplifiers if you want to (I drive 4). Then you can draw off the Front L&R to a separate amp for the 901's and the 'other' (lesser) speakers can live on the receiver's native amplifiers.

A separate multi-channel amp for the 901's was my solution. Because I can run each channel independently to an external amp, I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers (DBX DB-SW 15's) and the Rear Surround channel (Bose 301), 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 (Kenwood 777's) and Surround speakers (Bose 301's) from its own amps.

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.

** Multi-CH Receiver L&R Audio 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.

Any modern AV Receiver with the pre-requisite analog outputs should work. Since you have to buy a power amp for your 901 front channels anyway the receiver need not be a powerhouse. Look for features and lots of connections for digital and analog devices. I lean toward coaxial digital connectors because A) they take standard >> and cheap << audio cables; and B) they can be shared with Y-connectors if you're careful to have only one digital device turned on at a time. Optical SP/DIF is an expensive farce to get into your wallet.

For DVD/Cable Box/Blu-Ray look for multiple HDMI or component connections. Again, length and cable cost made me look at the component connections vs HDMI and I was pleased that I can't see the difference even with HD programming from my cable box. It's all great.

The symptom you described can be caused by any number of things. I always start with the output power transistors which are the first things to blow with a speaker output overload condition. Unplug the power cord to your unit, remove the top cover and use an ohmmeter to check resistance from C to E on all 10 of the power transistors (Q6050 thru 54 and Q6060 thru 64) attached to the large heat sink. Blown transistors typically read <1 ohm, compared to good transistors that are >10k ohms. If you find a bad transistor it will need to be replaced.
