Note: The input terminals are marked with indicators to show the polarity. Per International
Electrotechnical Commission (IEC) standards, a positive voltage on the positive marked input results
in the transducers moving outward. You must verify the positive and negative markings for each
respective product. Always tie the cable down to the available hardware to minimize any buzzing or
pullouts. If possible, after wiring is completed, play sound through the speaker to identify any
connection issues, buzzing, or rattling.
2.6 DSR1090 design simulations
There are
.gll
files that you can use to simulate the DSR1090 in acoustical simulation software.
You can download a folder (
Dolby_Surround_DSR1090_GLL_Files.zip
) that contains the
.gll
files
https://professional.dolby.com/product/cinema-audio-products/DSR1090/
. To run the
.gll
files, use
EASE or EASE Focus software. You can download the software from
https://focus.afmg.eu/index.php/fc-
.
Note: Dolby provides simulations for the DSR1090 in sidewall and overhead positions to meet the
needs of an installation.
DSR1090 .gll file descriptions
There are two DSR1090
.gll
files. The
Dolby_DSR1090_Sidewall.gll
file is for sidewall simulations
only. The zero-degree vertical aiming reference is at the back of the enclosure, and therefore the polar has a
built-in 15-degree downward angle from the transducers. The
Dolby_DSR1090_Overhead.gll
polar file
references the zero-degree vertical aiming reference to the front of the enclosure so that the transducers
directly point to the aiming location in the
.gll
file.
2.7 Additional information
There is additional information regarding the DSR1090 that you need to consider.
• System weight for stability calculations is approximately 14.1 kg (31 lb).
• Amplifier selection is aided by additional data, as indicated in the DSR1090 specifications.
• The power-draw specification provides the actual power draw in watts at the rated V
rms
in the design,
instead of calculated power. This can aid in optimizing amplifier power budgets, as the measured power
is almost always lower than the calculated power (sometimes significantly).
• The maximum voltage peak specification is useful for selecting an amplifier that has a voltage rail at or
above the rating for the speaker maximum dynamic performance. Some amplifier companies provide this
data in their respective technical data sheets (or provide the data by request).
