Trying to EQ my room today and I'm somewhat confused about microphones orientation

Should they be pointing towards the screen, or straight up (like in the marketing brochures ). Manual is unclear about this.

To me, having them pointed towards the screen makes more sense. Like this:

But every marketing picture shows them pointed straight up like this:



So which one is the correct way to position the calibration mics?

Doesn't matter, since the room correction is only addressing low frequencies (below 350Hz). I've typically pointed microphones straight up, whether using the Lex mics or measuring with REW or using a SPL meter.

Interesting question.

Old test with pointing towards the speakers: http://www.hometheaterhifi.com/volume_11_1/lexicon-mc-12-auto-room-correction-1-2004.html

When doing the manual set-up alternative with external sound level meter, it does make difference how to measure the speaker sound levels. Thefore I assume that it could make diference with automated option also.

I would suggest to test both alternatives and manual method also with documentation of all measured values to papere and see if the levels / distances are different with diferent mic pointing settings.

"in a clear line-of-sight path with the loudspeakers "

MC 12 v4 EQ:

MC 12HD EQ
http://www.lexicon.com/downloads/products/prod_15_634472770282055361_MC-12HD_EQ_R0.pdf

OT: any info when the smr lex forum opens again or a new lex is announced ......

New lex would be just enough with current number of channels but with D/A processing quality like in new Auralic VEGA DAC ! and same approach to A/D

Just a hunch... anything lexicon does that is praised at 6moons is likely wasting money that could have been spent on something producing tangible benefits. Just seeing that you are talking about a DAC, I am now certain that is the case.

MC 14 is there but no internal EQ.

Try MC14 or Bryston MP3 with DSP Antimode Dual Core 2.0 + the antimode sub box.

HK Management has lost their mind ....
