Looking for a list of receivers will run 901 Series 4 speakers with external equalizer for home theater use


The key to running the Bose 901s is to have the equalizer inserted into the tape monitor loop. Most 'old school' stereo receivers have tape monitor inputs. On an AV receiver, the VCR or CD analog inputs/outputs could be used but you will be limiting your listening to stereo sources. Please be aware that some AV receivers will not allow you to select different audio and video sources. The Marantz NR15xx, SRx004 receivers are pretty flexible, and allow you to pair up a component audio input with an HDMI (or other) video input. (No surround sound in this type of setup...)

Which home theater recivers are compatiable with the 901 equalizer and speakers?


The use of 901's in any digital AV receiver setup for anything EXCEPT STEREO listening through the 901's alone requires you to have a separate amplifier for them and to avoid having to use a Tape Monitor.

That is because if you activate any Tape Monitor circuit at all, you will kill any digital sources. That is a function of AV receivers in general, nothing to do with 901's. However, you can still draw the Front Left and Right signals out of any Pre-Out (with a Y-cable set, looping the Pre Out directly back to the Main In) or Tape Out jacks (remembering to NEVER activate that monitor on the receiver), go into the Active EQ's Amplifier Connections; then Out of the EQ's Amplifier Connection to a separate amp and attach the 901's to that amp. This way you won't introduce proprietary and potentially damaging Active Equalization back into anything in the AV Receiver with its conventional speakers.

Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them. On many, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others, you may have to borrow the signals from a typical Tape- or Adapter-Out RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won't have to switch IN. The signal Out is always there regardless of the monitor state.

The AV Receiver can still drive the Center, Surrounds and the Sub(s) as it is designed. This is how mine is wired.

Come to think of it, you could still have conventional Front L&R speakers on the AV Receiver, but why? Maybe one would prefer the 901's for music and some other speakers for surround. Level matching with the 901's to conventional front speakers would only be possible if the separate amp has its own volume, but it would work. Maybe I'll try it someday. None of my current amps has a volume control.

How do I connect my 901"s to my amp "NAD" 7600 power envelope ?


Bear in mind that 901's require exclusive use of any amplifier they use. You shouldn't expect to use conventional speakers alongside them on the Speaker B terminals. The reason is that the 901's require the uyse of their dedicated Active Equalizer to shape the frequency spectrun to match their drivers' response curves, resulting in a flat sound output. Applying that kind of equalization to any conventional speakers will sound to sharp at the extremes and may even potentially damage them.

You can use them in either of two ways.

Attach the Active Equalizer in your Tape 2 loop, following the clear guide printed on it. Activate Tape 2 to place the EQ in line with the program. Bypassing Tape 2 would show you what 901's sound like without their custom EQ curve. NEVER set the Copy function to 2>1 as this would introduce 901's EQ to whatever is on Tape 1.

or (recommended)...

TO preserve the use of your Tape attachments (through which you might also run any other kind of sound processor), remove the jumpers between the Pre Out and Normal In and attach the Active EQ there.

Should you anticipate using this rig in a multichannel setup from an AV receiver, just draw the AV receiver's Front L&R out from its Pre Out connectors, or from one of its Tape Out connectors, and into this amp's CD or Video Sound inputs. You would still have the flexibility to use the NAD for your Stereo-only rig, and your AV receiver's stereo sources would be available to it, too.

This is essentially how I run my 901's as the main speakers in my 7.1 home theatre.

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.

Panasonic av control receiver sa-he200


On any 5.1 system without 2 zone capabilities when you press speaker "B" the receiver uses the rear channel amplifiers to send signal to the remote speakers. As a result the receiver cannot output signal to both the rears and the remotes at the same time.

Conversion to home theatre


You will need a separate stereo amplifier for the 901's to accommodate the need for the Active EQ. There is no way to separate your receiver's front L&R channel preamplifiers from their amplifiers.

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. You would probably just get a nice 2-channel amplier for the 901's. If your receiver requires a powered Subwoofer so you would need another amplifier channel for that, too. Therefore, you might look around for a powerful 3- or 4-channel amplifier so you could drive the Sub, too.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. I'm using only 100W for mine and it has plenty of steam for the 901's.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ's Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

Not what you might want to hear but 901's have special requirements. I've had mine for 25 years and have no regrets.

A separate subwoofer channel on the amp could be used. Just run a single RCA channel from Sub OUT to one available channel IN on the amp and attach the subwoofer to it. Two would work, also. That's what I do. You could use a 1-2 RCA splitter to feed two available channels on a 4-channel amp. The iterations are many. Have fun.

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

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.
