ProDesk™ SAT 5 Active Satellite & SUB 8 Active Subwoofer
Owners Manual for 2.1 (Stereo) Applications Issue 1, rev 3
3. Quick
Setup
1.
Carefully remove the SAT 5 Active Satellite and the SUB 8 Active
Subwoofer from their respective packaging. Please make sure to
retain all packaging materials for future shipping requirements.
2.
The SAT 5 and SUB 8 leave the Blue Sky factory fully calibrated.
With the gain controls set to the reference mark (which is at 12
o’clock on the gain control) on the subwoofer and monitor
speakers, a 200mV -7dBu pink noise signal, with a bandwidth
of 500 to 2kHz, will yield 90dB SPL at 1 meter for the satellite.
Because most small monitoring rooms have some gain at low
frequency a good starting point for the subwoofer level is -3dB
from the reference position.
3.
The SAT 5 and SUB 8 use XLR connectors. You will need a total
of four (4) XLR cables for a stereo monitoring confi guration (not
supplied).
4.
The fi rst step in the installation process is to position the active
subwoofer. Although you have great fl exibility in where the
active subwoofer is positioned, a good starting point is centered
between the left and right satellite speakers. This could be under
the console, behind the console, etc.
5.
Once the subwoofer is in position; connect two XLR cables from
the left and right monitor outputs on the mixing console or digital
workstation to the Left and Right inputs on the subwoofer. Then
connect the remaining two XLR cables to the left and right satellite
outputs of the subwoofer. You will connect these cables at the
end of Step 6. Finally, Plug in the power cord to the IEC connector
on the subwoofer.
6.
Next, place the SAT 5 Active Satellite Speakers into position.
The recommended position for the monitors is based on ITU
standards and sets the speakers at 60 degrees from the listener,
forming an equilateral triangle (a triangle with equal sides). See
Figure 1. Fortunately, this setup eliminates most of the math and
is easily simplifi ed to the following guidelines: If you want to sit
1 meter (39.37 inches) from the speakers, place the speakers 1
meter apart. If you want to sit 6 ft from the speakers, place the
speakers 6 ft apart. Etc. The active monitors can be positioned
on the console, on stands, etc. Ideally the SAT 5 active monitors
should be at seated ear height. If this is not possible, tilting
the cabinet at the listening area can improve high-frequency
coverage.
7.
Once the left and right speakers are in position, plug the two XLR
cables from the subwoofers’ Left and Right outputs into each
of the SAT 5 inputs, and then plug the power cord into the IEC
connector on the SAT 5. Confi rm the system is wired as shown in
System Signal Connection Diagram on - page 6.
IMPORTANT!
Confi rm that the High-Pass fi lter switch is on the “IN”
circuit position. This switch will turn on the 80Hz High-Pass fi lter
that is required when using the SAT 5 in a 2.1 system with the
SUB 8. This switch should be in the “OUT” position only when the
SAT 5 is used with the SUB 12 or in a 5.1 system when being used
with the BMC. Visit www.abluesky.com for more information on
the BMC and SUB 12.
8.
At this point the Blue Sky monitoring system is correctly
confi gured, and ready for the fi nal step in the installation. Prior to
plugging the system into the wall, and powering up the system,
do a quick check of all connections.
9.
If everything is correct, plug in all power cords.
Do not turn
on the power switches, yet!
Some mixers and out-board
equipment such as D-to-A converters and equalizers generate
loud rail-to-rail pops when they initially turn-on. Depending
on the level and the gain settings of the monitors, these pops
could damage the tweeters in the SAT 5 monitors. To avoid this,
always turn on equipment in the following sequence: Mixer 1st,
subwoofer 2nd, and satellite speakers last.
10.
At this point the Blue Sky monitoring system is fully operational,
and ready for use. Begin by playing familiar pieces of music,
which can assist you in the fi ne-tuning and exact positioning of
both the active monitors and active subwoofer. It is important to
remember that the positioning of the subwoofer in the room will
impact the subwoofer level. You may fi nd it necessary to increase
or decrease the level from the reference position. This is OK, and
is anticipated.
11.
If a more exacting setup is required, a pink noise generator, used
in conjunction with a real time analyzer can be used to fully
optimize the system (See Page 10 - Expanded Setup Guide).
12.
Just remember - Use your ears, they are the best audio tool you
have and you will be amazed how accurate the setup can be if
you use familiar audio material during the setup of the system.
