Help with hooking up a Equalizer Please

[Markw]

Sigh...

Look, until you take it upon yourself to apply a little effort and learn about the signal flow in an audio system, you'll never be satisfied with any answer. After all, since you want to keep it to "just the facts", you need to be open to learning new ones yourself in order to understand the answers your questions.

As you can see, anyone can take one solitary line-level source, plug it into an eq, and then plug that eq into an aux input and make that one source work. But, to do it to alll non-digital sources connected to your receiver, you need that "tape monitor loop" that we, and Yamaha, keep on referring to.

If you really really want to learn what that thing is about instead of posting the same rant over and over, try clicking here for the best explanation I can give of that loop.

Hopefully, this will show you what you're up against. If not, you're on your own.

+1 with all due respect.

OP needs to learn and understand "signal loops", tape loops, effects/processor loops, etc.etc...............

Actually, I had assumed you did your homework in my previous post.

But apparantly I was wrong...

Can someone tell me if I have a Preamp output and Main amp input, that is maybe named different on the RX-V1000 ?

Did you even look at your own (linked) manual* before posting here? Look at the top of page 18.

It was suggested earlier (12 days ago in post 7) that you try inserting the eq between these. Did you? What happened?

So, please keep this in mind the next time you want to get all high and mighty on us, or at least me.

* Printed page 18, PDF page 22.

Very cool. It even has the generic Pre Out/Main In, Main In, Main Out labels! :thmbsp:

The Yamaha Owners' Manual for this very model says to do just what he wants to do just as I said to do it.
Their recommendation so...

Will you please quote the Manual (its page) where Yamaha says a word on equalizer connection? For to follow this “recommendation”…
===
===

The back of the receiver should have a Preamp output and Main amp input for the L/C/R. There is probably a "jumper" linking these.
Just remove the jumpers and connect the Preamp outs to your eqs inputs and your eqs outputs to the Main amp inputs and you got it.

You are quite right.

Most if not all domestic Equalizers...

The real quotation I answered was:

again, there have been quite a few threads on this. The place to put the eq is in the tape monitor, not just for convenience, but also for noise

You are quite right.

===
===

Most if not all domestic Equalizers sensitivity is -10dBu, the output of a pre-amp is in the region of +4dBV, and a power-amp will take +4dBV.....
So the pre-amp will have too much output for the EQ, and the EQ will not have enough output for the Power-amp, so you will have a gain miss-match....
You will end up driving the input of the EQ too hard to compensate for the lack of output.....this in most cases will make you system noisy.

They design the EQ's to match the sensitivity of Tape monitor/ Noise reduction adapters/inputs and record outputs because there are many amplifiers/receiver which don’t have pre out and main inputs, and most people want to use the EQ over all their inputs, the Tape monitor is the best way to facilitate this.....Their sensitivity is different from a pre-amp input and output......

Professional EQ's are different however and will not work very well in the Tape Monitor because pro EQ's are generally +4dbV

For the case of pro EQs in domestic amps, you are right about working voltages in appropriate cases.

For the topicstarter’s “Yamaha CGQ2015A” with its nominal 1,23 V “pass-through” “all flat” voltage, and his 0,15 V REC OUT level, the S/N ratio loss will be 18 dB, i.e. real S/N ratio will be 78 dB at 0,15 V. Which is not bad, taking into consideration decisive shortcomings of use of “PRE OUT” - “MAIN IN” circuit: use of “PRE OUT” - “MAIN IN” jacks is affected by “the BASS, TREBLE and BASS EXTENSION settings” (p. 18 of the Manual). And generally speaking, by filters, loudness circuit etc., contradicting the principle of sending the signal to external sound processors (equalizers, compressors, 3-head tape decks etc.) that must receive the signal “as is” from the system’s inputs (“sources”).

And the detailed mode I had proposed in my post of 06-26-2011, 01:10 PM, has it failed?

Just remove the jumpers and connect the Preamp outs to your eqs inputs and your eqs outputs to the Main amp inputs and you got it.

I am no expert at this at all. Thank YOU for YOUR help. You were right on track, as you will see after these following post. I was not sure among the 60 plus inputs where these jacks were, and did not see a jumper. That why I asked at a forum like this for just a little curtious help.

 

[jgscott]

Just had a look at the Equalizer the OP is using, which obviously nobody else did, the EQ is a professional EQ and looking at the specs it can be used between the pre-amp/power-amp, its rated at +4db, I assume its dbV, so YES you CAN and it will work just fine.......

Yep Ditto to what toddalin said. Great call also. Thank you also for looking at the EQ specs.

 

[jgscott]

Well having a couple of the Yamaha 31-band pro eqs and a big Yamaha receiver, I can point to reasons why the OP would NOT WANT TO USE THE TAPE LOOP.

First off, the tape loop only monitors the source physically selected at the receiver. IOW, if the user wants to switch from television to CD, he has to physically get up and walk over to the receiver to switch the tape monitor to CD. The tape source does not change with the listening source selected.

Next, the tape monitor outputs will only output from analog sources. If the receiver is doing the converting from digital to analog, nothing (or noise) comes out the tape outs.

So, just maybe Yamaha knew what they were doing when they recommended using the pre-out/main in for eqs.

Yep. In Japan they knew, but........ NOT at Yamaha Customer Service USA in Calif !

Who are we to argue with the people that made your stuff. That bolded line is the key to the equation, and was pretty much made clear in that linked thread.Sometimes you just can't get there from here.

Nope. not with an optical cable. Your EQ is analog. One would have hoped that after all the brou-ha-ha on this, tha tdfact's iportance would hav esunk in. Now,maybe if you used an analog out to the receiver but, even then, with the configuration of that EQ, it's implementation would be cumbersome and it's use would be limited to only that device.

Ah, once I was able to weed thru all the "WRONG & USELESS post and info here that confused me from figuring out what the 2 people said about my RX-V1000 and MY MODEL EQ, Guess what, it worked for all sources thru the Preamp output and Main amp input.

Ahh, I got there from there.

"Yep" = "It failed".

Let me sum this up. I kinda wished that any who did not look at the info I posted about the 2 peices of equipment, or did not know, would have not posted. I made a mistake and overlooked the pre in & out. Anyone else want to own up to their mistakes here to ?

I am no expert and was not very knowlegable about this. All those post that did not apply in this case, just made it worst for me to figure it out, or even understand what the 2 poster who were right and looked at the equipment said.

I did look at the info on the 2 peice's of equipment. Do you think I would have posted asking for help if I had figured it out and had it already connected right.:scratch2:

BTW, that EQ is sweet, and let me talior my sound for the room I have, and I like it. :thmbsp:

I have a Yamaha model # CGQ2015A Dual Channel 2/3 octave Equalizer. On the back it has a Channel A and channel B what looks like a Phone/Mic OUTPUT jack, and a Channel A and Channel B Phone/Mic INPUT jack.

Im trying to tie it into a Yamaha RX-V1000 Receiver. And a pair of speakers to EQ them. I'm thinking I have to get a Phone/Mic male connector from Radio shack or somewhere and make 4 plugins for the 2 output females and 2 input females on the EQ. Then connect A/B output from the EQ to the left and right speaker?

Then run the other 2 A/B - Left Right to the back of the receiver with RCA plugins. Is this the right way ?

And where would I input to the receiver ? Would I go from input on the EQ to the left right speaker A connectors in the receiver amp ? Is this right ? ( I'm sure it's Not)

Also is a 2/3 octave Equalizer good ?

Here are the EQ specs - http://usa.yamaha.com/products/live_sound/processors/gq2015a/?mode=model

Here is the Yamaha RX-V1000 pdf of the rear of the Receiver-

I have a awareness issue ? You just said the key "I'm overmatched". And a 2nd childish name calling.

I'm not in a match. Sounds like your having a WWW Big Temper Tantrum.

I haven't understood. No need to clarify WHAT was the RESULT, and not "nice ways"?

Strange manner!..
