The above description is incorrect about the subs getting full range. Here is how it works from my experience

Front large/sub yes/surround large
All frequencies to fronts/surround
Sub only gets the 0.1 of any audio below the xover

Front small/sub yes
Fronts/surrounds get all above xover
Sub gets all below xover for all channels

Front large/sub yes/surround small
Front is full range
Sub is 0.1 or anything below xover frequency for small speakers
Surround is anything above xover

Front large/sub plus/surround large
Front full range
Sub gets all below xover
Surrounds full range

The sub will never go above the cross over if one is set no matter if it's set to yes or plus

Hope that helps

P.s. Wish you could have different speaker settings on different mcacc profiles ensive:

Does anyone know the specifics of how MCACC Pro handles dual subs? Does it adjust delays between the two to get the best results? How does it EQ them? By MCACC Pro I mean what the sc-85 and above have. it seems a lot of people are calling MCACC Advanced something it is not (pro).

I haven't come across many MCACC experts anywhere, unlike the depth of knowledge on Audyssey by comparison. I have a system with SC-LX88 that runs a ML Motion based system with 2 x ML Dynamo 1000's. The results are very good with MCACC. How exactly it handles EQ'ing and delay vs say Audyssey I couldn't be sure. The subs aren't positioned symmetrically in this system either, there still at left and right sides of the room, however one is tucked in next cabinet and the other under a staircase. If I was to compare to a Steinway system with twin subs (symmetrical under screen 4 ft apart), that I also own elsewhere, the quality of the MCACC results does not compare badly at all. So to me that's saying something of MCACC's ability to deal with dual subs. If you really need a technical answer, you may need to try emailing Pioneer directly about it perhaps.

Hi There,

Need help as i bought pioneer VSX1123K AV receiver recently and when i try to set that up in my living room to the TV and to 5 in ceiling speakers. I was just following the instructions on quick setup and put HDMI cable out to out 1 on receiver and the input to one of the HDMIs on TV. selected receiver button and then home setup button to show MCACC on receiver but i don't see any thing getting displayed on TV and is keep on displaying no signal.
Initially i thought its a bad HDMI and i connected that HDMI to ROKU or BD player from TV and it detects it and shows on TV screen but when i connect the same HDMI to receiver i don't get anything.

I am new to receivers, please help. your help is much appreciated. TIA

Gotcha. If you read the MCACC Pro blurb on Pioneer's site it sounds pretty good. It is only on the SC-85 and up from what I can see. Main thing I would like to see when I upgrade from the SC-63 is the dual calibration. The SC-63 was labeled as 7.2 but in reality the .2 is really just a split .1, they are not independent. I found an SVS AS EQ1 to use for now. Here is MCACC Pro.....

Now, MCACC® (Multi-Channel Acoustic Calibration) is taken to a new level of performance with MCACC Pro. Designed by Pioneer for the Atmos-enabled Elite system, MCACC Pro calibrates sound output using a microphone to monitor the sound environment and an equalizer to optimize and precision-tune each speaker to the room. How advanced is MCACC Pro? So advanced that Pioneer engineers have included dual independent subwoofer outputs, each with individual EQ. Tailoring left- and right-channel low frequency response curves lets you achieve optimum subwoofer performance based on specific room placement, creating powerful bass response and seamless integration with your main speaker system. With the push of a button, it’s like having a professional acoustical engineer fine-tune your home theater system.

Looks like the Vsx1130 vsx90 have the dual sub calibrations. Also on one of those two product pages there is a pamphlet explaining the different versions of MCACC

I prefer the amps in the SC series personally. I will check out th eproduct pages...if it's what I have seen in the past it didn't get into much detail.

Ok, I just watched a video from the web site. It independently EQ's both subwoofers and adjusts phase between ALL channels..so I would assume it adjusts the two subs for the ideal sound. Now I want to switch to something with MCACC Pro

Good find. I never really went searching for in depth data on MCACC Pro. Interesting read.

Question:

For some strange reason mcacc always thinks my front speakers are out of phase with the center + rears.

Amp: Pioneer Elite SC LX87
Fronts: Wharfedale Jade 7 - 4 way - 1" tweeter / 3" mid / 6.5" mid woofer / 2x 8" woofers
Center: Wharfedale Jade 2c - 3 way - 1" tweeter / 3" mid / 2x 5.25" woofers
Rear: Wharfedale Jade 5 - 3 way - 1" tweeter / 3" mid / 2x6.5" woofer

Do you think my speakers might be wired wrong internally?
I have checked all my wiring and there are definitely no mistakes there.
I've tried repositioning the speakers and mic, and it always thinks my Jade 7s are out of phase with my Jade 5/2c.

Anything's possible but in most cases distance/reflections cause the signal to be inverted when measured. MCACC will correct it so I would ignore it (as the manual says) and move on.
