How does one EQ with the 990? Is there no way, without an outboard unit, to smooth out your room spikes, or am I missing it?

Thanks.

The 990 does not offer any onboard EQ capability. They haven't ruled it out as a possible future addition through a firmware update - Sherwood offers some EQ on their P-965, but that particular implementation apparently didn't offer what Outlaw felt was necessary for the 990. At this point, though, the only EQ option provided by Outlaw is the Velodyne SMS-1 , which they've put together a good supplemental guide for.

I, too, felt that EQ would be helpful. I found two products from ALESIS . I employ both in different rooms at home.

In the living room where I have a 7700 I use the Alesis DEQ 830 , an 8 channel EQ with many presets and you can change according to the material if you wish. And the connections are T-R-S balanced, perfect for a 990-7700 environment.

If you only need two channels eqd there is the DEQ 230. Also balanced TRS I/O. Both have 1/3 octave EQs.

Given that there is one A/D and another D/A conversion taking place, do you notice any loss of clarity?

Not at all...and as mentioned they are in different systems. The DEQ830 is between 990-7700. Between the 990 and 755 I have two, because it's a 4 ch room. I'm not running video there. running either stereo or 4 ch. The 4 ch is run thru the 7.1 directs, using just four of them.

BTW if concerned about A-D and D-A one can use stricly analog EQs.

Some may think 990 is overkill for just audio. I disagree because it is so clean. I did try the 970. Was grateful that outlaw allowed it to be returned, because it isn't as clean and transparent as the 990.

When talking about room EQs and sound degradation, just adding the EQ inline is technically adding noise to the signal. If you don't use the EQ to boost any frequencies, then this noise shouldn't be noticeable. If you're worried about the quality of sound, you're better off trying to treat your room acoustically and experiment with speaker positioning than adding a device that adds more electronics to your audio signal. Hope that makes sense...

You are correct. However we really don't have a dedicated HT. It's just in our hexagonal living room. We are somewhat constrained. Fortunately the achieved sound is good. But thanks.

Many times I looked at my overgrown rack and thought "To hell with all those extra units, EQ's and the rest".
Lemme try just the amp now...
But:
After one night trying to be happy with just that and experiencing the boomy sound I couldn't wait to set up the EQ's again!

I was (and am) also worried about the extra converters, but to tell you the truth I never actually HEARD any difference with "direct", no sharp edges, nothing...

Today I finished setting up my sub with the SMS-1 and checking with my generator, and I now found a very linear respons, nicely integrating with the 60/80Hz crossover.

Still need the stereo EQ for the fronts, as my main room mode is +17dB @ 100Hz, which is way above the crossover frequency.
I'm going to try a 120Hz crossover, but I think that will not benefit the sound quality because bass will be too directive.

I agree room treatment is the best thing thing, but in my room it's just impossible.

hi everyone:

When it comes to sound quality, Every setup is different. There are too many varibles. One person may see the need for using an EQ and another may not . Let me give you a situation. my father and I have basicly the same setup. Same TV, tv stand, same cables, Same speakers, same pre/pro, same amp, same dvd player, same DTV receiver. Basicly If I like something, I buy 2 one for me and one for him and vice versa. However, we have different rooms. I have a small dedicated HT room, and he has his setup in his very big with an inclining roof bedroom/ tv/ht room.

Both systems sound excellent but very different. What do you think about that? As far as room treatment, After my experience, you shoud consider you room as a component in your setup. if you are considering room treatments, first of all do not add all of them at once so you don't put too much to not have a dead room. Secondly do some research. Its not a mater that should be taken lightly.

I thaught my room was impossibe also but after reading I realized that room treatments make the impossible possible.

Why is your room Impossible?

I agree. Room treatments can make a horrible room sound good. My HT is basically in a 12X42 foot tube. If you click on my sig. you can see I devoted some attention to room acoustics and could probably still stand to tweak a bit. It has made a big difference so far.
