PREMIUM PR:O Active 1.4

3 Tips and Tricks

1 Do not expose electronic circuitry to moisture!
Protect cabinets against rain when you set them
up outdoors. Keep soft drinks, beer, and any other
liquids away from the electronic components to
prevent short circuits.
2 PREMIUM PR:O active enclosures provide opti-
mum sound to you, so be sure to provide optimum
input signals to them! Noise such as humming is
generally caused by defective cables, the wrong
type of cords, or unbalanced signals routed into the
mixing console. Check all signal and mains cables.
3 Prevent distortion! Not only is it unpleasant to your
audience's ears, it also endangers your equipment.
Make sure all components that are connected
directly and indirectly to PREMIUM PR:O active
cabinets have sufficient power ratings, and that
they don't distort because they're running at their
respective limits. Ensure all sources deliver clean
audio signals.
4 Avoid ground loops! Annoying humming can arise
even within audio 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 different 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!
CAUTION: Never tape over the plug's ground
terminal - this endangers lives!

4 Troubleshooting

The POWER LED does not light up when switched
on.
• Check if the mains cord is plugged into the Mains
Input.
• Check if the mains power supply is providing
current.
The Power LED lights up red, flashing intermittently.
• The Limiter has actuated; lower the input level if
necessary.
The Power LED lights up red continuously, but no
sound is issuing from the cabinet.
• The enclosure's protective circuit has tripped.
Please contact your authorized dealer.
The rendered music sounds distorted.
• Check your mixing console's LED meters. They
should not be constantly in the red. If necessary,
back off the volume at the mixer.
• If the LED displays on your mixer are in the green,
back off the PREMIUM PR:O active cabinet's Gain
knob.
• Observe the Limiter LEDs on the PREMIUM PR:O
active enclosure's control panel. These may light up
red, but only intermittently. The red light may not
illuminate continuously. If it does, turn down the
Gain knob.
