I am considering picking one or possibly two of these up. Does anyone on the forum use or have any experience with this equalizer? I have found it for $794.72 shipped. Figuring I could probably get two for an even better deal. I would be able to use two units for the 9 channels and 2 subs I will eventually use in my setup. If anyone has seen these cheaper, please let me know. It seems as if they are somewhat scare on the web.

Thanks!

Be careful ;)

What do you have as a processor? Receiver? Does it have pre amp out and amp in? If not, you will have problems.

How do you have 9 channels? Any of it monosignal source?

You should really consider 1/3 octave EQ and may even need more for the sub ch. You may need to do a real time frequency analysis of your setup first to see how bad it is.

That eq will not work on a stand alone HT receiver. Today's units don't have the same type of tape loop (simple tape monitor button) as in the past. That (along with all other eq's) are for analog signals.

You can't eq a digital coax signal properly. There's a thread on this a few months back that's really informative.

The way to hook up that eq is between a pre-amp or receiver and separate power amps. I was able to hook a 10 band 2 channel eq through my Denon 3805, but had to use zone 2 and zone 1 to adjust things - a real pain in the neck. So much hassle it wasn't worth it. Plus, the 3805 has it's own internal eq that adjusts all digital and analog signals. Zone 2/3 on the Denon's only handle analog, not digital. If future units allow for digital, it could work, but not without hassle.

Some receivers have pre amp out and amp in :D

Sorry guys, I guess I should have given more info. I have a Yamaha RX-v2500 used as a pre/pro and two Outlaw 755 amplifiers. I have the following channels: L,C,R,RS,RB,LB,LS,L Presence, R Presence, and 2 SVS20-39CS+ subs. Currently, I can only run 7.2 or with the Yammy's inabilility to run both Surround Back and Presence channels at the same time. Eventually, I plan on running a full 9.2 system when Yamaha gets their act together and makes this available in a mid-level receiver where Presence and Surround back can be run together and they give us stereo sub outputs.

The Bijou does 11 bands of 1/3 octave equalization between 80Hz and 800Hz of the front and center channels. It does dual-bandwidth (2/3 octave and 1 octave -- 4 band of each for a total of 8 bands) equalization between 100Hz and 6.3kHz of the surround channels. It does 12 bands of 1/6 octave equalization between 22.4Hz and 80HZ for the subwoofer.

I have done RTA with a software program and have found the room, as probably most any room, could benefit from equalization. If I pick up 1 or 2 of the Bijou EQs, I would get a good RTA to perform the equalization. I am looking into the Rane RA30 RTA, but am not sure if this would fit into the system (connection wise) and be the best way to try and balance it or not.

I also do not fully understand this concept; maybe someone can clarify. If I used a piece like the Rane RA30 RTA, do I just plug the RTA into the wall and connect the mic and then perform all my EQ using the Bijou until it is properly aligned on the display of the Rane RTA? Or, does the RTA have to actually be wired through the system? Now, I know to use the test tones provided with the Rane, I would have to throw it into the loop. However, couldn't I just use test tones from a disc with the mic and the RTA? I mean, if all channels are EQ'd with the same signal, regardless of where it comes from, they should all sound very close to the same and this is what EQ is all about. Please let me know if I am off base here.

Thanks!

Which? My Denon (which is pretty generous with connections) has an EXT in, but are used for inputting multi-channel audio signals from an outboard decoder such as a DVD audio player, or a SACD player. You don't want to loop an eq through your EXT in. :D

Yup, that one doesn't. :mad:
Onkyo? The older models used to anyhow. Older Yam?

Check out Audio Contol's 1/3 octave.
You can use an EQ in a channel that has a pre out but then you have to have the output of the EQ go to an amp. Not sure if that Yam has amp inputs. If so, you can use those channels.

No, the RTA doesn't have to be wired through the system, unless that RTA has internal test tones that you want to use. Mount the mic of the RTA on a tripod at the listening position.
You may want to compare prices.

That's the big issue.

No one is going to buy an older, outdated receiver just to hook up an outboard eq. If this Denon 3805 can't do it, I don't know of any newer models that will. Thus, the reason for that huge thread on outboard eq's.

Manufacturer's really missed the boat on the new HT receivers by not having connections to easily hook up external eq's. It infuriates me to no end. I've always used outboard eq's. :mad: :mad:

Unless you are expanding to 6.1 or 7.1, nothing wrong with those older ones that were done right :D

Yes, it should be triple if none of the new receivers have amp in.
