Quick Setup / With Filter Setting Instructions - BLUE SKY SUB 8 UNIVERSAL Owner's Manual

4. 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. [SUB 8 Universal - What is included?].
2. The SUB 8 Universal is compatible with XLR input / output
connections. For more information on connecting your system,
please see page 6 [System Signal Connection].
4. The first step in the installation process is to position the 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 9 [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].
6. Our recommended position for the nearfield 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 your nearfields should be at
seated ear height. If this is not possible, tilting the cabinet at the
listening area can improve high-frequency coverage.
7. Once all the nearfields are properly placed, connect your left
nearfield monitors to the left output on the back of the sub, via
XLR cable. Now do the same for the right channel, connecting the
right nearfield to the right output. 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].
8. At this point the 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 your monitors. To avoid this,
always turn on equipment in the following sequence: All sources
and mixer first, and then the SUB 8 Universal and the rest of your
monitoring system.
10. It is now time to set the Variable Cutoff Frequency on the back of
the SUB 8 Universal to best match your nearfield monitoring system.
To determine the proper filter setting on the SUB 8 Universal, you
first need to know the cutoff frequency of your nearfield monitors.
This can typically be found in the manual, under specifications and
may look like this: 40Hz to 20kHz +/-3dB. The low frequency
cutoff off for the monitor in this example would be around 40Hz.
We recommend you set the SUB 8 Universal one octave above
this cutoff frequency. To go up one octave, multiply the LF cutoff
frequency times two. In our example this would be 80Hz, because
2 x 40Hz = 80Hz. Make sure to set both the left and right
channel to the same setting.
11.
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 first the level and then the placement
of the 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 of the
subwoofer to best match your nearfield monitors. Again use a
familiar piece of music which includes plenty of LF material to help
you set the proper level.
12.
If a more exacting setup is required, using test signals and a SPL
meter, please see Page 9 [Expanded Calibration Guide].
13. 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.
14. Congratulations! You have now completed the "quick setup" of the
SUB 8 Universal. If you have any questions, please do not hesitate
