Quick Setup
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. [2.1 System - What is included?].
2.
MediaDesk systems leave the Blue Sky factory fully calibrated.
With the 2.1 gain control set to the reference mark (which is at 12
o'clock on the gain control) and the input attenuator set to +12dBu,
a 200mV (-11.7dBu) 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 frequencies a good
starting point for the subwoofer level is -3dB from the reference
position. For more information with regard to controls, see page 7
[A Tour of the 2.1 MediaDesk amplifier and I/O].
3.
MediaDesk is compatible with XLR and RCA input connections. If
you need to connect MediaDesk to a sound card or need more
information on connecting your system please see page 6. You
will need a total of two (2) XLR or RCA inputs cables for a stereo
monitoring configuration (not supplied). For more information
on connecting your system, please see page 6 [System Signal
Connection and Level Settings].
4.
The first step in the installation process is to position the active
subwoofer. Although you have great flexibility with regard to
where the 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. For
an expanded subwoofer placement guide, please see page 10
[Subwoofer Placement Guide].
5.
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 Connection and Level Settings].
6.
Next, place the MediaDesk 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 1 meter (39.37 inches)
from the speakers, place the speakers 1 meter apart. If you want
to sit 2 ft from the speakers, place the speakers 2 ft apart. Etc. The
monitors can be positioned on a console, desk, on stands, etc.
Ideally the MediaDesk SAT 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 [MediaDesk SAT mounting and placement options].
7.
Once all the SATs are properly placed, connect the speaker wire
from the left high-level outputs on the back of the sub, to the input
on the left SAT. Now do the same for the right channel, connecting
the right output to the right SAT. Please make sure that you connect
positive to positive and negative to negative, so that both SATs
are in-phase. Lastly, please plug in the power cord to the IEC
connector on the subwoofer. Prior to proceeding confirm that
the system is wired correctly, as shown on page 6 [System Signal
Connection and Level Settings].
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 cord into the wall outlet.
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 MediaDesk monitoring system.
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 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 audio material during the setup of the system.
13.
Congratulations! You have now completed the set up of one of
the world's finest monitoring systems. If you have any questions,
please do not hesitate to contact us directly with your questions.
