Sat 12 Mounting And Placement - BLUE SKY SAT 12 Owner's Manual

6. SAT 12 Mounting &
Placement
Monitor mounting and placement is often an afterthought, but in order to get
the best imaging and overall performance from the SAT 12, it is important to
place the speakers correctly.
Monitoring Height:
Figure 1 shows the ideal monitoring height, with the SAT 12
located perfectly at seated ear height. If this is not possible,
tilting the cabinet at the listening area can improve high-frequency
coverage.
Monitoring Angle:
The recommended position for the monitors is based on an ITU
standard and sets the speakers at 60 degrees from the listener,
forming an equilateral triangle (a triangle with equal sides) - See
Figure 2. Fortunately, this setup eliminates most of the math and
is easily simplified to the following guidelines: If you want to sit 2
meters from the speakers, place the speakers 2 meters apart. If you
want to sit 9 ft. from the speakers, place the speakers 9 ft. apart
Etc.
Wall Mount Options:
The SAT 12 is compatible with OmiMount® 120 Series brackets,
via the 1/4 X 20 inserts located in the bottom and the back of the
cabinet. The OmniMount® 120 brackets are designed to support
up to 120 pounds of weight when properly installed. Please visit
www.omnimount.com for more information, including detailed
mounting instructions. Please see page 18 [Cabinet Dimensions]
for more information on insert locations. Also see page 3 [Safety
Instructions] item 17 "MOUNTING".
Mounting the SAT 12 in a baffle wall / soffit:
IMPORTANT: It is highly recommended that you check all of your
local electrical and safety codes, to make sure that all regulations
are going to be met before mounting the SAT 12 in a baffle wall.
Requirements and recommendations:
1) Important Requirement: Proper cooling and airflow shall be
provided to the back of the SAT 12 / Heatsink.
2) Recommendation: In order to build an affective baffle wall,
it is best to use a design with considerable mass, that doesn't
produce sympathetic resonances. Using three layers of 5/8" (50
mm) Gypsum, with overlapped joints, and the appropriate wood
framing has been found to be affective (again, consult local
building codes and an engineer or architect for specific design
guidelines).
3) Recommendation: To avoid sympathetic vibrations, it is best
to physically decouple the SAT 12 from the baffle wall structure.
An effective way to do this is to use Mason Super W neoprene or
natural rubber pads (durometer 40). One Super W pad should be
placed under each corner of the speaker.
4) Recommendation: Mount the SAT 12 flush with the front of the
baffle wall and seal all gaps around the SAT 12 and the baffle wall
using a rubber, foam or neoprene gasket material. This will improve
the HF frequency response, by reducing any cabinet or edge
diffraction related problems (again, check local building codes).
5) Recommendation: The SAT 12 includes four primary baffle
compensation settings, each of which reduces the MF to LF "bump"

that typically results from mounting a speaker in a baffle wall. The
amount of compensation needed is dependent on room acoustics
and the size and type of baffle wall. The only way to accurately
determine the amount of compensation needed is to use a high
resolution acoustic analyzer, such as MLSSA, TEF, etc. For more
information please see page 6 & 7 [A Tour of the SAT 12 Amplifier
& Electronics] and page 15 [Measurement Data].
Mounting the SAT 12 behind an acoustical transparent screen:
If you intend to place the SAT 12 behind an acoustically transparent
screen, it is recommend that you use a screen that provides the
minimum amount of acoustic loss at high frequencies, such as the
Microperf screens offered by Stewart Filmscreen (www.stewart
filmscreen.com). Additionally, it is also recommended that you
add some acoustically absorptive material to the wall behind the
screen, to help absorb HF reflection from the screen. Typically 2"
of black duct liner, or other fiberglass acoustical blanket can work
well (check local building and safety codes for possible restrictions
and guidelines).
