1.
If you haven't already done so, carefully remove all items from the
packaging and confirm that everything that is listed on page 4 is
included [SUB 212 - What is included?].
2.
The SUB 212, is compatible with balanced XLR connectors /
cables. The total number of XLR cables needed will depend on
the system configuration. However for a basic 2.1 system, with
one sub, you need a minimum of four XLR Cables. For more
information on connecting your system, please see page 6
[System Signal Flow & Connections].
3.
The first step in the installation process is to position the active
subwoofer. Although you have great flexibility with regard to
where an active subwoofer can be placed, a good starting point
is centered between the left and right satellite speakers. This
could be under a console / desk, behind the console / desk,
etc. If you are using multiple subwoofers, you have even more
flexibility. For an expanded subwoofer placement guide, please
see page 10 [Subwoofer Placement Guide].
4.
Once the subwoofer is in position, connect the two input cables
from the left and right analog outputs from the mixing console,
digital workstation or other source, to the left and right inputs
on the subwoofer.
For more information on connecting your
system, please see page 6 [System Signal Flow & Connections].
5.
Next, place the SATs into position. 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 1. 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. Ideally
the SATs should be at seated ear height. If this is not possible,
tilting the cabinet at the listening area can improve high-frequency
coverage.
6.
Once all the SATs are properly placed, connect the XLR cables
from the left output on the back of the sub, to the 80Hz input on
the left SAT. Now do the same for the right channel, connecting
the right output to the right SAT. Lastly, please plug the power
cords into the IEC connectors on the SATs and the subwoofer(s).
Prior to proceeding confirm that the system is wired correctly, as
shown on page 6 [System Signal Flow & Connections].
8.
At this point the Blue Sky monitoring system is correctly
configured, and ready for the final step in the installation. Prior
to plugging the system into the wall outlet, and powering up
the system, do a final quick check of all connections and level
settings.
9.
If everything is correct, plug the power cords into an appropriate
outlet / circuit. 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 setting of the monitoring
system, these pops could damage the monitors. To avoid this,
always turn on equipment in the following sequence: All sources

and mixer first, and then the monitoring system. Reverse this
procedure when shutting down your equipment.
At this point the Blue Sky monitoring system is fully operational,
and ready for use. Begin by playing familiar pieces of music
(preferably reference quality recordings, with dynamic and full-
range sound) which can assist you in the fine-tuning and exact
positioning of both the SATs and the active subwoofer. It is
important to remember that the positioning of the subwoofer
in the room will impact the subwoofer level. You may find it
necessary to increase or decrease the level from the reference
position. This is OK, and is anticipated.
If a more exacting setup is required, using test signals and a SPL
meter, please see Page 7 [Expanded Calibration Guide].
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, high quality audio material during the setup of
the system.
Congratulations! You have now completed the setup of one of the
world's finest monitoring systems. If you have any questions,
