Auto Stand-by
(PR:O 118 Sub D2 only)
The built-in amp switches to standby mode (Consumption around 0.5
watts) when the button is set to „On" and the unit does not receive a signal
for 180 minutes. To power the subwoofer back up again, simply set its
Power button to „Off " for fi ve seconds and then back to On. The subwoofer
will remain up and running if you disable Auto Stand-by by setting this
button to „Off ".
2.2 Setting Up and Connecting the Cabinet
Use a balanced cord equipped with XLR connectors or 6.3 mm (1/4") jack
plugs to route the signal from the mixer (via a monitor out, line out, or
a similar output) to the Input. Then connect the active satellites to the
XLR outputs labeled Line Out Mid/High. Use the two Thru ports to feed
the fullrange signal to other enclosures. Make sure the XLR connectors'
terminals are confi gured as follows: 1= ground, 2= +, 3= -.

2.3 Operating Speakers

• Ensure the powered PREMIUM PR:O cabinet is switched off .
• Back the Gain knobs all the way off , turning them counterclockwise as far
as they will go.
Ensure you fi rst switch on all other connected components, for example,
a connected mixing console as well as all signal sources patched into it,
such as keyboards, instrument amps, eff ects and so forth. Always connect
PREMIUM PR:O active cabinets to Line Out Mid/High, and always switch
them on last; that is, after you switch on all other connected components.
When you powering down, fi rst turn the Gain knobs to the far left and
switch active cabinets off fi rst, before switching off any connected devices.
After you power the system up by engaging the Power switch, a system
check prompts the fan to briefl y kick on and back off again in about fi ve
seconds. The fan is temperature-controlled, actuating only at very high
volumes and temperatures requiring cooling.
• The Limiter/Status LED lights up green when the cabinet receives mains
power.
Set the Gain knob to the center or 12 o'clock position (= 0 dBV). This is the
preferred level if you have connected a mixer to the PREMIUM PR:O active
cabinet. You can boost the input level 6 dB by turning up the Gain knob.
For the best audio results, ensure the Limiter/Status LED does not light up
continuously red.

Adjusting volume with the Gain knob
Twist this knob to adjust the line signal levels.
If you hear distortion or saturated signals, fi rst check the signal sources
and, if possible, reduce the output signal level there. If you cannot adjust
the level of the signal routed to the PREMIUM PR:O active cabinet at the
source, match it to the power amps by backing off the Gain knob to lower
the input level.

systems with balanced circuits, for example, when the mixing console's
mains cord isn't connected and grounded to the same mains circuit as
PREMIUM PR:O active enclosures. Using two diff erent ground circuits can
create a ground loop. To prevent this problem, always connect PREMIUM
PR:O active enclosures and the mixing console to the same electrical
circuit; that is, the same phase!
