Using an Extenal EQ on a Denon AVR2808CI ??

[Pipelayer]

I know what you are saying... NOooo! But this is for something else. One of my hobbies is an Audio Engineer, you know; recording entertainers in a recording studio. When acquiring recording material or checking out material I just recorded after a session, there is a need to see how it sounds on several types of consumer systems (expensive and inexpensive). There sometimes arises a need for me to bring out (on that consumer system) certian instruments and harmonics, in other words to isolate the piano from the guitar or the drum from the bass, etc. In "multi-channel studio record mode" I would simply turn down each separate instrument on each separate track but once it has be mixed down to stereo the only way to separate and isolate them is through frequency, which is usually done by a very good and surgical like EQ.

On the stereo systems they have the "Tape Monitor I/Os" that will allow you to patch in an EQ over several sources, like tape, CD, AM-FM tuner, etc.

My question being: "Is there anyway to do this on a AV receiver"? It wouldn't really have to cover all 7.1 channels, most of this work I will be doing in stereo mode.

Thank you

Well, if the receiver doesn't have those tape loops, most likely not, it needs a pre-out and then you need an ext amp as most consumer receivers that do have these outs no longer have amp-in.
When you EQ two channels, it will affect all instruments in that FR that you are altering.
One thing to consider is not the component but the speakers being used to reproduce the music and the room acoustics the speaker is in.

Actually, the 2808 does have the "PRE-OUTS" for all 7.1 channels as you stated, it also has something that says "EXT. IN" for the same 7.1 channels. I hooked the EQ's left and right inputs to the front left and right PRE-OUTs and theh EQ's left and right output to the front left and right EXT. IN's. Everything plays as normal but no EQ effect. If you go to Denon's website and download the 2808CI manual you can see a diagram of the PRE-OUT & EXT. IN that I'm talking about. Thanks

The ext in is for a multichannel source, not an amplifier input. You could use an eq between the source and the receiver, that is the only way it will work.

Hope this was helpful.

Maybe I'm a purist, but I cringe at the thought of using an external EQ. In hindsight, when I was younger, I used one for some time. The sound seemed rather compressed, but I wanted it for bass control. If Im not mistaken the Denon has an EQ with the Audyssey any way. Tape loop EQs are obsolete. My current receiver sounds very good with out one. I'm sure the 2808 would too.

I good EQ has its place, as most speakers are not completely flat responce (not anywhere close to it). Enhancing or detracting from certain bands of frequency is a good idea, but it isn't the easiest thing to do.

I think I read somewhere that it is a bad idea to use an external EQ (tape loop) with a surround sound receiver as it severly colors/affects/compresses the surround effect. I forget where. If I can find I'll post a link. Maybe I'm wrong here.

If you use a tape monitor loop to connect the equalizer, it won't do you much good. Using only the tape monitor you will be using Dolby Pro-Logic, not Dolby Digital, because to tape loop is analog. You'd be missing the digital benefit completely, which is huge.

Read the OP, he isn't using it for surround sound.

 

[croseiv]

In that case then yes, but my point is still valid. Assuming he will at some point wish to listen in surround sound, he should remove the EQ.

Since the receiver doesn't have tape loops he can only use the EQ with 2-3 analog sources. If you remember how an EQ works it can be used between the source and the receiver (so the way of connections would go source-EQ-receiver). Decent EQs usually have more than one set of inputs, at least one other, to connect a different source. Think of it as adding an external device to a CD player to alter the sound (which is what this is doing) it works for the CD player not the receiver. When an input is changed on the receiver the EQ is doing nothing with the EQ, hence it affects nothing but the CD player or other recording playback device he plans to use to listen to recordings.

EQs also have a bypass feature that disables all equalization and other features of the EQ aside from switching.

Pipelayer, if you plan to use the EQ to do mixing the receiver need not be involved. If the recording device has a headphone facility it would be wise to use some studio monitor headphones to do your mixing instead of using your stereo speakers, as they are not likely to have a flat in room response. Recording studios use headphones or nearfield monitors to mix recordings, because they are fairly flat in response.

It would and could if you apply it before the processor in there for any DD prologic, etc. However, a pre out is after the processing and it will do not much. And, the EQ is not for the receiver, they are rather flat in FR but for the room EQ of the speaker. As Seth indicated, no speakers are flat, and even if they were, the room will affect its response in that room, that is what you EQ. EQ is used everywhere in the recording and mastering process.
The only pure path is in an auditorium in a seat After that, no minimal stuff is found.

Do you mean between a specific source like a CD player then EQ then receiver hook-up? So are you saying there is no way I could use it across the board as with a tape mon hook-up which would patch the EQ in over any source?

That is correct.

Thanks good buddy!

EQ in the recording industry? Get out of here. I guess you think I was raised in a barn. My point is, I would not use one in my set-up as it is and go to great lengths to avoid them (yes I know my receiver uses EQ for the auto set-up). They tend to color the sound when running stuff through them (I'm thinking analog mid-fi here)-Pipelayer is after something else though.

You are right, he is after getting flat sound for recording. So why are we discussing this on his thread?

...They tend to color the sound when running stuff through them .

And the speakers? They don't color the sound when they are not accurate?
