Pioneer vsx 1020 K receiver. I connected the bose 901 eq to the tape in and tape out but it doesn.t seem to be compatible.

You will need to use both tape monitor loops with the RG-2 in one loop and the BOSE 901 EQ in the other.

See: https://deercreekaudio.com/resources#f467075b-ce37-49ea-b5f7-10e8eb2aa4f6

901's will need dedicated amps, if that helps. You can only use the Zone-X pre-outs. Page 31.

You want them to be your Main Front speakers, right? The news is not good.

There will be some limitations because you can't extract a 'processed' Front L-R from this receiver. The following will give you good stereo and Front L-R from the 901's but it won't allow central volume control or send them any of the DSP effects you may select. Sorry. If it had a Front L-R Pre-Out you'd be good to go for all functions and listening modes.

You'll need a separate stereo amplifier WITH ITS OWN VOLUME CONTROL for the 901's to accommodate the need for the Active EQ. 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.

With this receiver we have to cheat to get the Front L-R signal out to the 901's (but it's unprocessed and at a steady MAXIMUM volume level)...

For connection I would run a pair of RCA cables from the VCR/DVR Audio Out L-R OUT jacks (*) 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.

* You'll lose the ability to use these jacks for anything else, but few of us use them anyway. DO NOT select this function for monitoring or you lose all audio in the VSX.

This receiver has no pre-amp outs to drive the required separate amp the 901's need for you to continue to have multichannel digital audio. The reason: activation of a tape loop disables digital inputs. But they DID give you Front Height. Oh boy.

Not knowing anything about your specific amplifier or if it correctly configured for the 901 Active Eq, the first thing I would say is these are designed for analog stereo sources ONLY and a multichannel digital-capable receiver will NOT work properly with any devcie in a Tape loop.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

Connect the Active EQ between the pre-outs and the amp input. Run speaker assignment, levels, etc and have fun.

This works for all models of AV receivers when you want 901's as Front L&R 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.

Patch the Active EQ directly off that point (Amp In from the receiver, Amp Out to the new amp). Run all the speaker level settings on the AV Receiver and rock on.

I'm not sure that receiver is compatible with outboard EQs like the 901 EQ. This receiver is also not on Bose's 901 EQ compatibility chart, so it's possible that this is not going to work at all. You could call Pioneer and ask if this receiver is compatible with ANY outboard gear (such as EQs, compressors etc) but I don't think it is.. The tape in/ tape out I think is only for 1 source.. That's the problem with new receivers, they expect that nobody will want to connect any external gear (like back in the day) because everything is built in.

I wrote 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! With one caveat - My receiver actually has 5.1 analog Outputs so I can drive up to 6 external amplifiers if I want to (I drive 4). IF yours does NOT (*) we have to be creative in extracting the front two channels from your multi-channel receiver. The obvious alternative place would be at one of the few OUTputs on the back, assuming you have one free to use.

* I can't find your exact manual so I have to extrapolate features.

I see on the SR>6003< there are Pre Audio OUTS so I'm betting your receiver does, too.

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; (or VCR or Tape Out if you don't have Pre 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.

*** If you use a Tape or VCR Out you will NOT be able to SELECT the source you use for the 901 Pre-Outs for listening, or else the 901's will not get any sound sent their way. DO NOT USE the monitor switch for that source.

how do I hook up the bose 901 EQ to a yamaha DSP3090??

any pre-out should work. i believe the bose have a rca jack connector for attaching to the receiver. look at the new receiver connection diagram. any output that is rca designed for use by a recording device will send a signal that the 901's can see.
always check the manual on both before connecting for any precautions.
good luck
