Antimode 8033 - Page 11

post #301 of 554
Anti-Mode 8033S(-II) has two inputs, they are summed before the processing (which is performed in mono). The outputs are normal phase and inverted phase, and make it possible to build a RCA->XLR adapter to get differential output (although normally RCA is good enough). Also, if your sub can invert phase, you can put an 'inverted sub' to the 180-degree output and the other to the 0-degree output, and they will play in the same phase (thus you save one Y-splitter).

To the actual question: yes, you can still use one unit for 2 or more subs, as long as they get the same signal. In general dual mono subs is better than stereo subs (smoother response).

So what you're saying is that I'd use only 1 output from my AVR --> 8033S --> Y-splitter cable --> 2 subs.

I have done it with 4 subs and presently do it with 3 Submersives. One out from the AVR to the 8033 and one out to the subs via Y splitters. They kick ass!

I had no idea you can split your signal line so many times! Do you have some kind of amplified splitter or super high end cable? 3 Submersives has to sound pretty boss!! cool.gif

The LFE signal does not get degraded thru a couple of Y splitters. Yeh, 3 Submersives is BOSS! In my sig is the link to my HT room.

Your surround speakers are rather adequate aren't they? tongue.gif Looks like a whole lot of sound thumping around in that room!

I'm curious-- you have so many absorptive acoustic panels on the walls, but why no diffusive panels behind the seating?

Oh, and +1 for the Serenity poster! wink.gif

There are 3 Gik Monster Bass traps behind the seating next to the Serenity poster. See pic #8 on my HT site.

Yeah, I can see the bass traps, but was just curious why you didn't add any diffusive panels behind your seats?

Well i just got the Anti Mode 8033Cinima, and ran the Auto CAL, mind you i just did it really quick this morning before work, i listened to only like 1 min of a song, LOL, but i switched to By-Pass, and then the Auto CAL, and while the By-Pass was louder, it didnt sound as good, it was more BOOMY, and when i switched back to the Auto CAL, it was much better, i didnt listen to it LOUD, as it was early in the morning, but i will know more this Saturday, when i can listen at LOUDER VOL.

How many of you calibrated the wider area correction (the second sweep tone)? How big does your room need to be for that to help at all? Also, how many of you guys are using either of the lift settings?

Gik engineer said that I don't need them.

How accurate is the Antimode mic as compared to a calibrated mic from Cross Spectrum?

I believe they are the official USA dealer for the Anti-Mode. Great to deal with and shipped fast as well.

Two years later I realize but maybe they've changed. I ordered the Antimode 8033s from simplifiaudio on Sep 3 (a holiday) last week. It's now the 10th and no contact from seller whatsoever. No email to confirm, no response to my email or whatever.

they were at CEDIA last week so they are probably playing catch up this week.

They contacted me last night and yeah the CEDIA was the reason. Not trying to be difficult but when doing business for the first time with a company via internet I feel a lot better with a confirmation and all. That said they seem to be on it so no worries.

Please tell me you were so frustrated that you kicked a few unfortunate elves? tongue.gif

Wanting to optimize my SVS 13Ultra, I decided to REW it
The sub is connected to a Denon3808 via the 0 phase output of the AntiMode8033.
With the AM8033 in Bypass mode, I ran the Audyssey XT calibration, using only 3 positions.
I then switched off the avr and ran the AM 8033 self calibration.
I then proceeded to do REW.

For Raw U13FR, the Audyssey Eq is OFF and the AM8033 set to BYPass.
For AudysseyXT FR, the AVR's Eq is set to Audyssey On and the AM8033 set to bypass.
For AM8033 FR only, the Audyssy is set to off with the AM8033 active.
The last graph is a full calibration with AudysseyXT and with the AM8033 active in the chain.

I found the Audyssey XT did very little to the raw 13U FR. Is the above methodolgy somehow affecting the reading

When you combined the XT and the 8033 did you run the XT first and then the 8033 second or did you just combine the independent calibrations? Running them in order would have a much different (likely better) effect than just combining their independent calibrations where they may be doubly trying to fix the same frequency causing a worse response than without them.

Based on my experience with Audyssey MultEQ XT, it does almost nothing to EQ the bass...so I guess in your case, it looks normal.

Can you post the before and after Antimode "DECAY" graph? I'm interested in how Antimode can reduce bass ringing.
post #321 of 554
The individual REW FR of XT and AM8033 were done separately.
AM8033 self calibration done first. Then set to ByPass.
Then I did the Audyssey XT 3 position only calibration (with AM8033 still in ByPass)

For REW measurements,
AM8033 done with the Audyssey on the AVR set to OFF. AM8033 active.
AudysseyXT done with AM8033 set to ByPass and the Audyssey On on the AVR.
For Raw FR, I switch of Audyssey and set AM8033 to Bypass.

The combined FR is a separate 6 position AudysseyXT calibration with AM8033 active in the chain.

These are the DECAY of RAW without any calibration and with AM8033.
The difference is audible with reduced ringing. My ceiling rattles are no longer audible.

Calibrate the Antimode first, then run Audyssey.
post #324 of 554
Yes, that is exactly what I did as the last step to obtain the 'combined' REW FR of the XT and AM8033.

I'm a bit unsure, I'm afraid. Is the "after" graph showing the 8033 by itself, or the 8033 combined with Audyssey?
post #326 of 554
If you use 2 subs with the Anti Mode does 1 need to be at 180 PHASE?. THANKS

The 2nd sub output on the Antimode is 180 phased. The subwoofer connected to it has to be set at 180 too. 180+180=360=0. This results in 0 phased. In the end, the 1st and the 2nd sub will be at the same phase, which is 0.
post #328 of 554
OK, well i have the Cinema version, so it only has 1 sub out.

It is only with the AntiMode 8033. No Audyssey calibration .
It does a good job of taming the modes esp between 40Hz and 80Hz .
