Audio/HiFi Question

I picked up a Denon AVR receiver to replace my 38 year old Vector Research VR7000 that was starting to have some issues. I have been using Bose 901's along with their passive EQ this whole time. I am having trouble making the eq work with the new receiver through the tape input/output jacks which is the proper way to make the connection. Do these new digital receivers not work with eq's? Any help will be appreciated in getting the 901's hooked up.
 
I don't see why it wouldn't work, but most modern receivers have a set of canned EQ curves built in. They're not always the best though.

Anyway, I believe it should go

Recevier Tape Out -> Equalizer In
Equalizer Out -> Receiver Tape In

Of course, the Tape Monitor button must be engaged to activate the tape loop.

Does your new receiver have a Tape Monitor loop? It may not. :shrug:
 
Probably doesn't have a tape monitor loop on the avr. If your eq has a selector switch you can run your sources through that and then into the avr.
 
I keep reading that the 901's are not compatible with any receiver that doesn't have a tape monitor switch. I really didn't want to have to buy new speakers but may have too.

What? I've never heard of such a thing. They don't just connect to the standard speaker outputs? Did they have some sort of non-standard equalizer that was custom to the 901s?
 
Yes. They need the eq to sound great. New equipment doesn't have a tape monitor switch as tape decks are not being used any longer. The Vector had a tape monitor switch which allowed the eq to be heard. Denon does not. Tech changes and now there is a lack of compatibility between old and new. Progress

Crazy...never seen a setup like that before...but Bose 901s were always a bit rich for my blood.
 
Run your source into the input on the eq. Run the output of the eq to the input on your avr. That will work but you're limited to one source. You can swap cables for different sources or buy a $25 source selector switch.
 
Buy a optimus or realistic eq off of eBay. Cost you less than $50. Will give you active eq with 2 sources and a cool spectrum display.

901's were essentially large array of midrange speakers. They had very little bass response, so the Bose equalizer boosted the mid bass to produce reasonable bass response. IIRC, the equalizer also boosted treble to make up for the drivers' lack thereof.

A little sleuthing turns up this which purports to be the curve the equalizer uses. I don't know why there are multiple lines (are there multiple setting on the Bose EQ?)

See if you can replicate this using the graphic EQ in your new receiver. I assume each vertical division is 3dB
