Page 8 • User Manual • Mounting & Placement
Monitor mounting and placement is often an afterthought, but in order to get
the best imaging and overall performance from the SAT 8, it is important to
place the speakers correctly.
Monitoring Height:
Figure 1 shows the ideal monitoring height, with the SAT 8
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 8 is compatible with OmiMount® 60 Series brackets,
via the 1/4 X 20 inserts located in the bottom and the back
of the cabinet. The OmniMount® 60 brackets are designed
to support up to 60 pounds of weight when properly installed.
Please visit www.omnimount.com for more information,
including detailed mounting instructions. Please see page 13
[Technical Specifications & Dimensions] for more information on
insert locations. Also see page 3 [Safety Instructions] item 17
“MOUNTING”.
Mounting the SAT 8 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 8 in a baffle wall.
Requirements and recommendations:
1) Important Requirement: Proper cooling and airflow shall be
provided to the back of the SAT 8 / 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 8 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 8 flush with the front of the
baffle wall and seal all gaps around the SAT 8 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 8 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 8
Amplifier & Electronics] and page 14 [Measurement Data].
Mounting the SAT 8 behind an acoustical transparent screen:
If you intend to place the SAT 8 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.
stewartfilmscreen.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).
