Author Topic: Imax "laser aligned" sound Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-07-2010 05:24 PM                     On Imax website I read that Imax delivers "laser-aligned digital sound that envelops you". What does it mean? Is it a Marketing nonsense or does it mean something? Cheers  |  IP: Logged Jonathan Althaus Master Film Handler Posts: 435 From: Bedford, TX Registered: Dec 2008 posted 01-07-2010 06:45 PM                     Isn't all digital sound "laser aligned"? Sounds like marketing fluff to me.  |  IP: Logged Adam Martin I'm not even gonna point out the irony. Posts: 3686 From: Dallas, TX Registered: Nov 2000 posted 01-07-2010 09:47 PM                     A laser is attached to the speaker cabinet and used to aim the speaker at a specific spot in the auditorium.  |  IP: Logged Chris Aulisio Film Handler Posts: 2 From: Mesa AZ Registered: Nov 2009 posted 01-07-2010 10:25 PM                     The why does IMAX still use the Microphones to set sound?? Adam, if you still have my number from Century Days call me. I can not PM you, I'm too new  |  IP: Logged Adam Martin I'm not even gonna point out the irony. Posts: 3686 From: Dallas, TX Registered: Nov 2000 posted 01-07-2010 10:35 PM                     The laser is related to speaker coverage and the microphone is related to EQ.  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 01-07-2010 11:00 PM                     "Laser aligned." Yeah, when I play a CD in a CD player it plays "laser aligned" audio! Haw haw.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-08-2010 06:02 AM                     I see. And does it make such a big difference to advertise it as the only feature about its sound system?  |  IP: Logged Mark J.

I use my EARS! Everything else (mikes, EQ, multiplexers) is only used for confirmation. Ears first and last; instrumentation in the middle.

I've had an adaptor that I use with my Alignotron and mount it to the back of the horns. Louis.,.. you can't tell by ear where two feet above the rear center seat is at... What does it sound like at three feet and four feet above that same seat commpared to two feet ? And what about the seats on each side... What does that sound like?

Aiming is easy. At the National in Washington DC, it was necessary to stack 4675 horns on each channel. It was decided to cover the main floor with the lower horns and the 3 balconies with the upper horns. The point of interference was put on the front of the first balcony. Put a mike there, airm the lower horn, kill the audio to it and then aim the upper horn, then reconnect both. Job done!
