Yamaha CR-2020 Connection Help

[guptonr]

I would like to find an alternate way to connect a Bose 901 equalizer to my CR-2020. I normally run HPM-100s as my main speakers, but when I need to fill the room, I use the Bose 901 IVs. The 901s are connected to the B speaker outputs and the equalizer is routed through the pre-out/in connections and this works well. I don't even have to disconnect the equalizer when I use the HPMs because of the pre-out/in defeat switch. However, I want to use my pre in connections for another purpose.

Do any of you know a way to connect the equalizer through one of the tape loops? It would be simple on other receivers but the CR-2020 doesn't have a "tape monitor" button. It has separate controls for selecting recording source input and listening source out put. If I connect the equalizer to tape 1 in and out I end up with no source. The permutations of the selector/connector choices are many.

If you select tape 1 on both selectors, won't that do what you want?

I've tried that and it doesn't work. It just gives me a loop through the equalizer. One switch selects the source of music for listening (tape 1, tape 2, tuner, phono, aux) and the other selects the source for recording (tape 1, tape 2, tuner, phono, aux). The tape 1's "rec out" goes to the equalizer's pre-out connection; the equalizers "to amp" connection goes into "rec in" for tape 1. On most receivers this would work fine by selecting tape monitor to heare the source through the equalizer. It appears the listening selection and the recording selection are completely independent instead of the recording source always being the listening source. If I select tape one as my listening input, its source is itself (the equalizer).

I've got an 820 so I know what you are saying and it's confusing.
Have you tried in-tape1 out tape-2?

Just guessing.

Put it in a tape loop, put your source into the EQ and use the switch for tape on the EQ.

There is a way to do it I just don't have it here in front of me at the moment.

Pooshan: I've tried that. It doesn't work. If I select the source, Aux (cdp) for example, that's what I hear. The rec selector is separate. What goes through the equalizer doesn't come out the other end.

Detailman: That might work, I'll try it when I get home this weekend. I could select the source going to tape 2 (rec out) and hear it through tape 1. I hope it works, I'm trying to figure out a way to keep it connected and not have to move connections around all the time.

Cabinover: I think that would be a partial fix. The source would go through the EQ, but the problem being it would always go through the EQ. The problem is the type of EQ. THE 901 is an active equalizer and provides a lot of boost, essential for the 901s but not needed/wanted on the HPMs, and it doesn't have a bypass. The EQ does have it's own tape loop too so I'll play with that also.

Like I said earlier, it's confusing. There are 5 pairs of in/out connections and 2 selector switches with 5 positions each. I figure only one combination will result in my desired result. It's like cracking a safe.

Thanks for all ya'lls help. It gives me some other ideas where to go. I can get the results by simply switching connections, but that's a pain and puts stress on the connections and wires each time I do it.

There is also the "Dolby FM Adaptor". Try hooking up to a "Tape Out" and the "Dolby In", then engage the Dolby switch on the front and set your REC source to the Input you want.

Maybe. :scratch2:

There's a thread around here somewhere about using the Dolby as an additional input. That might have helpful info. :yes:

Thanks for the heads up to the link.

It looks like the dolby angle just may work. I'll get a chance to hook it up early next week. That may be the combination I was looking for: tape 1 or 2 out to EQ "in"; EQ "out" to Dolby in; tuner selected on input selector; desired source on record selector; dolby selector engaged.

While Yamaha used that "being able to record from one source while listening to another" as part of their selling points, I agree, more often than not it just confuses people.

It especially makes us older folks look foolish doesn't it? :lmao:

Another, albeit complicated way to accomplish this is as follows:
You could purchase another amp (find one cheap at a used stereo/repair shop or ebay; I'm sure lots of Audiokarmers could give you suggestions).
Buy a male-2 female "y" connector and hook to your "pre-out".
Use one stereo pair for your Bose EQ along with the new/used amp, and the other for your additional needs.
If the "pre-out" is simply not an option, purchase a pair of high/low inverters (found at any car stereo seller). You would have to make sure there is no impedence mis-match that would cause problems with the Yamaha...again I'm sure some AudioKarmers could help.
Hook the inverter input wires to the Speaker B terminals, and the RCA output to the Bose EQ. Again, use the new/used amp for the 901's.
Both ways would let you use the volume and all pre-amp controls on the Yamaha without any need for a tape loop/dolby/etc.
I did this to make an poor-man's output from a TV that had no RCA sound output: I had to get to the TV speakers and splice wires connecting to the TV speaker wires...hooked these to an inverter, connected the RCA's to a Jensen IsoMax C12RR transformer to get rid of the nasty cable TV hum; then connected this to the Aux input of my Sansui 9090 db. It sounds surprisingly
good...not home theater, but much better that the 2 1/2 inch POS TV speakers!
Good Luck

hook it up to the dolby adapter just as you did to the pre in/main out jacks and it will work fine

We have a winner!!

First off, I thank all of you for helping and giving me ideas. Now, what happened.

Dolby Adapter Connection: partial success. The Bose EQ connected just fine, but the only source going through the EQ was the tuner. I think the adapter must be hardwired to the tuner. So this solution would work if i used the tuner only.

The Winner: Pooshan!!! I went back and tried the Tape 2 Rec Out to EQ "From Amp" and the EQ "To Amp" to Tape 2 In and Tape 2 out to Tape 1 in. At first neither connection worked as I was making the same mistake I made earlier by selecting a tape as source and rec out. I thought I had to pick one of the tapes as a recording output. Apparently, both Rec Out connections are always "hot" and never have to be selected. With this connection, the Rec Out selector became the source selector. I leave the input selector in tape 2 (or 1, which ever the "to amp" is connected to) and can change sources by selecting different recording sources (tuner, phono, aux, etc).

Now I can use my pre in/out for a connection to a yet un-purchased HT receiver pre-out to occasionally run the HPM 100s through the CR 2020’s power amp as front speakers (easily disabled with the pre in/out de-coupling switch) and use my 901s with EQ with just the turn of a couple of selectors. No switching of connections involved.

Thanks AK!

Looking back on it makes me feel a little stupid. It's a lot simpler than I made it out to be. I thought I had to select which tape was doing the recording but they both always do and no selection is necessary. Duh. The "Rec Out" selector actually selects the "Rec Out" source, what will those crafty Japanese think of next.
