Quick 2.1 System Setup Instructions - BLUE SKY ProDesk SAT 5 MK II Owner's Manual

4. Quick 2.1 System
Setup Instructions
1. Blue Sky monitoring systems leave the factory fully calibrated. With
the gain control on the SAT 5 MK II 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 8
Universal or 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 level 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 5 MK II Amplifier & Electronics] .
2. The SAT 5 MK II, SUB 8 / Universal, 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 13
[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 5 MK IIs 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 1 meter from the speakers,
place the speakers 1 meter apart. If you want to sit 4 ft. from the
speakers, place the speakers 4 ft. apart Etc. Ideally the SAT 5 MK
II 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 5 MK II
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 input on the left SAT 5
MK II. Now do the same for the right channel, connecting the right
output to the right SAT 5 MK II. Lastly, please plug the power cords
into the IEC connectors on the SAT 5 MK IIs and the subwoofer(s).
Prior to proceeding confirm that the system is wired correctly, as
Figure 1
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. Also confirm that
the SAT 5 MK II High Pass Switch is in the correct position. See page
4 "Important notes about the SAT 5 MK II and this Owner's Manual"
for more information.
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 9 [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
