6. A Tour of the SUB 8

Universal Amplifier
and I/O

LEFT / RIGHT XLR IN

- These XLR inputs should be connected to

the left / right output of your console or digital workstation.  The
inputs  are  electronically  balanced.    Do  not  connect  more  than
one source to these inputs.  Refer to page 6 for more information
[System Signal Connection].

LEFT / RIGHT XLR OUT

- These XLR outputs should be connected

to the inputs of your left / right nearfield monitors. The outputs are
electronically balanced. [System Signal Connection].

VARIABLE / SAT 5 FILTER SWITCH

- This switch is used to either

activate  the  variable  state  filters,  or  activate    the  fixed  80Hz  low
pass filter that is required for use with the SAT 5.  If you are using the
SUB 8 Universal with the SAT 5, it must be set to the SAT 5 position.
Additionally, you will also need to set the 80Hz High Pass Filter on
the SAT 5 so that it is “in” circuit.

VOLTAGE SELECTOR SWITCH-

This switch can be set to either 115

Volts or 230 volts. Prior to powering this unit, please confirm that
the Voltage selector switch, located on the back of the subwoofer,
has been set to the correct voltage setting. If you are unsure of
the type of power that is supplied to your home / studio, consult
your product dealer or local power company. If your changing
the Voltage, please also confirm the proper fuse is installed [see
number 6].

POWER SWITCH -

Controls the power to the amplifier and all

internal electronics.

FUSE -

Replace with same rating and type for your local voltage

rating. For 115V applications use a 2 Amp T 250V and for 230 Volt
applications use a 1.25 Amp T 250V fuse.

IEC RECEPTACLE

- Check voltage selector switch before connecting

power. Connect to 115 Volt AC / 60Hz power source, rated for
200 WATTS or 230 Volt / 50Hz rated for 200 WATTS. Only use the
supplied power cord or an IEC approved power cord with a safety
ground pin.

AMPLIFIER HEATSINK-

The heatsink provides essential cooling to

the amplifier inside the SUB 8 Universal. Please ensure that proper
air circulation is available for proper cooling.

VARIABLE CUTOFF FREQUENCY CONTROL KNOBS -

These

controls are for adjusting the dual 24dB per octave low and high-
pass filters.  The cutoff frequency can be adjusted from 50Hz to
160Hz.  It is recommended that the SUB 8 Universal filters be set
one octave above the natural roll off of the nearfield monitors that
are being used with the SUB 8 Universal. To activate these variable
filters,  the  VARIABLE  /  SAT  5  FILTER  SWITCH  -  must  be  in  the  up
position (VARIABLE).  For more information see item 10 on page 4
[Quick Setup / with universal filter instructions].

10.

SUB GAIN -

This knob controls the input sensitivity of the

subwoofer amplifier only. When set to the reference position a
100mV signal at the input equals 90dB output at a meter.

11.

SUB Out -

This balanced XLR output can feed additional

subwoofers for increased bass performance and should be
connected to the SUB IN of an additional Blue Sky SUB 8 / SUB 8
Universal. The output contains the summed low passed subwoofer
output and the SUB IN audio.

12.

SUB IN -

This XLR input can be connected to either the subwoofer

output of an external bass-management controller, or the “daisy-
chain” output of a SUB 8 / SUB 8 Universal. This input is full-
bandwidth (up to approximately 200Hz) and does not use a low
pass filter.
