System Signal Connections And Level Settings - BLUE SKY EXO User Manual

Below are some basic outlines of ways someone may interface
eXo with their audio system. These may or may not apply to your
specific application, but they should be able to show the basic
concept for most applications. Please note that all inputs can be
used simultaneously.
CABLE WIRING SPECIFICATIONS
Most users of the eXo system will be using ready made
cables, however if you need to wire your own cables,
follow the wiring specifications below.
XLR / TRS 'COMBO' INPUTS (ELECTRONICALLY BALANCED)
Figure 2: Shows the XLR inputs being fed from the output
of a standard pro audio mixer. The eXo XLR / TRS inputs
can handle up to +30dBu of signal level at the input, when
the input gain switch is set to the -12dB position, and are
compatible with most, if not all professional gear.
INPUT GAIN SWITCHES (XLR / TRS INPUTS ONLY)
Certain professional audio devices have
a great deal of electrical output and gain
(up to +24dBu or more) and under certain
conditions it may not be advantageous to
reduce the output gain from your source
(such as with a D to A converter). Under these conditions
we recommend that you switch the input switches to the
-12dB setting. However, if you are not running the signal
into the XLR / TRS inputs at a high level and you are
interested in more gain from the monitoring system or
you want to match the voltage sensitivity of our other
products, then set the switches to the 0dB position.
RCA AND 3.5mm STEREO INPUTS
Figure 2: The RCA and 3.5mm inputs on eXo are
compatible with a myriad of consumer and computer
audio gear, such as mixers, CD players, Hi-Fi pre-amps,
mp3 players etc.
3.5mm HEADPHONE / EARPHONE OUTPUT
Located on the front of the eXo remote / preamp
is a 3.5mm headphone jack. The impedance of
the headphones should be 16 ohms or above.
When headphones are connected to this jack, the output
to the eXo Stereo Monitoring System is muted. Warning:
Permanent hearing loss may occur if earphones or
headphones are used at high volume.
SPEAKER LEVEL OUTPUTS AND INPUTS
This drawing shows the proper way to
insert bare wire into the binding posts
which are on the subwoofer outputs and
SAT inputs. When inserting bare wire, please make sure
that there are no strands protruding out that may create
a short-circuit. These binding posts are compatible with
wire gauges up to approximately 10 gauge.

REMOTE / PREAMP AND SAT CONNECTIONS
Figure 3, shows the basic connections of the included
system components. Please note: Turn off power when
connecting or disconnecting the remote / pre-amp from
the back of the subwoofer.
SYSTEM GAIN AND SUBWOOFER LEVEL
Shown in the drawing below are some basic guidelines for
setting both the system gain and subwoofer level.
System Gain (GAIN): You will notice that the normal gain
/ level setting for headphones is lower, when compared
to typical setting when using the eXo stereo monitoring
system. In order to avoid unpleasant and possibly
dangerous headphone playback levels, always turn down
the system gain when going to or from headphones.
Warning: Permanent hearing loss may occur if earphones
or headphones are used at high volume.

Subwoofer Level (SUB): There are several marks around
the SUB level knob, which show some general guidelines
for setting SUB level. Because all rooms / studios are
unique, your actual SUB level setting may vary.
