SVC online – Array or not to array: Part 1 – Additional data

At long last I have found some time to post here again. Well actually I don’t have the time but I did it anyway. The thing is – I left a trap in an article I wrote that would force me to make time here – and it worked!   This will be brief – […]

SIM3 Optimization & Design Seminar at UC Irvine

We just completed a 4-day SIM3 training seminar in the south side of southern California. UC Irvine is located very near the ocean, which makes one wonder how folks could study when the surf’s up. It is also right next to John Wayne Airport. Naturally I flew in and out of LAX, and drove the hour down to the other […]

Macau COD Tuning: Day 6 – Constellation

Constellation Tuning Most of today was dedicated to Constellation tuning. Steve Ellison programmed up the menu of user-settable presets that will become the painter’s pallette for the system designers, Francois Bergeron and Vikram Kirby. The pallette gives them easily understood parameters such as the the reverb Time, gain, etc, that will allow them to tailor the response […]

Macau COD Tuning: Day 5 (Cardioid sub day)

Looking for Mr. Cardioid During the daytime (remember that we start at 11pm) the crew set up 2 measurement mics for us high in the grid. The mics were placed as a front/back pair in the near field of the coupled subwoofer array. The goal was to measure the responses in front and behind on the center axis […]

Macau COD Tuning: Day 2

Day 2: Day 2 was spent finishing the tuning process for the Main arrays (to the 1/2 point) Now that we have done all 4 arrays we will copy the the settings over to the other side and then verify the symmetry of the other speakers. We are setting that part aside, moving on instead with […]

Macau COD Tuning: Day 1

I am currently in Macau. If you don’t know where Macau is, study up on the history of the Portuguese Empire. Macau,  the #1 gambling destination in the world has now reverted back to ownership by the People’s Republic of China and like all gambling operations serves as a funnel of money back to the […]

Subwoofer Delay Taper (Update 1)

Here is a quick preview of my next post.  These plots contain concentric circles. Each represents a wavelength traveled from the speaker at 125 Hz (2.73 meters). The first one shows 7 speakers spaced at 1/2 wavelength (1.37m) and all set to 0 ms delay. The concentric are all the same for the 7 speakers […]

Uncoupled Array Design: Beginnings and Endings (Updated)

** Update:  A downloadable version of the calculator to do this work is available (courtesy of Daniel Lundberg). Go to the bottom of this post for preview and instructions.  ______________________________________ When a coupled array is assembled, its operating range is limited primarily by its power capability. Even very large arrays will congeal fairly quickly and once […]
