Blue Sky monitoring systems leave the factory fully calibrated.
With the gain control on the SAT 265 set to the reference mark, a
200mV (-11.7dBu) pink noise signal, with a bandwidth of 500 to
2kHz, will yield 90dB SPL at 1 meter. With the gain on the SUB
12 set to the reference mark, or -9dB on the SUB 15, 100mV
(-13.7dBu) pink noise signal, with a bandwidth of 40Hz to 80Hz,
on one of the inputs, will yield 90dB of output at 1 meter. Because
most control rooms have some gain at low frequencies a good
starting point for the subwoofer level is -3dB from the reference
position. If you are using multiple subs, the gain may need to be
even lower than this (depends on the acoustics of the studio and
the placement of the subs). For more information with regard to
the controls, please see the manual that came with the SUB 12
or SUB 15, and page 6 & 7 of this manual [A Tour of the SAT 265
Amplifier & Electronics].

The SAT 265, SUB 212, SUB 12 and SUB 15 are 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 9 [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 12 [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.
system, please see page 9 [System Signal Flow & Connections].
5.
Next, place the SAT 265s 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 3.
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 SAT 265 should be at seated ear height. If this is
not possible, tilting the cabinet at the listening area can improve
high-frequency coverage. For more information about placement
see page 8 [SAT 265 mounting and placement].
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 265. Now do the same for the right channel,
connecting the right output to the right SAT 265. Lastly, please
plug the power cords into the IEC connectors on the SAT 265s
and the subwoofer(s). Prior to proceeding confirm that the

system is wired correctly, as shown on page 9 [System Signal
Flow & Connections].

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.
10.
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.
11.
If a more exacting setup is required, using test signals and a SPL
meter, please see Page 11 [Expanded Calibration 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, high quality audio material during the setup of
the system.
