1. Blue Sky monitoring systems leave the factory fully calibrated.
With the gain control on the SAT 6.5 EXR 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 6.5 EXR Amplifier & Electronics].
2. The SAT 6.5 EXR, 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. For more information on connecting your
system, please see page 9 [System Signal Flow & Connections].
5. Next, place the SAT 6.5 EXRs 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 6.5 EXR 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 6.5 EXR 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 6.5 EXR. Now do the same for the right channel,
connecting the right output to the right SAT 6.5 EXR. Lastly,
please plug the power cords into the IEC connectors on the SAT
6.5 EXRs and the subwoofer(s). Prior to proceeding confirm that
the system is wired correctly, as shown on page 9 [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.
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.
13. Congratulations! You have now completed the setup of one
of the world’s finest monitoring systems. If you have any
questions, please do not hesitate to contact us directly with
