Setting Up And Connecting The Cabinets; Operating Speakers; Settings - HK Audio PREMIUM PR:O 8 A Mode D'emploi

2.2 Setting Up and Connecting
the Cabinet
Connect cords routed from your mixer (monitor
out, line out, or a similar output) to the balan-
ced Input sockets using a cord equipped with
standard XLR microphone connectors. Then
connect the active satellites to the XLR outputs
labeled X-Over Out. Use the two Through ports
to feed the fullrange signal to other enclosures.
Make sure the XLR connectors' terminals are
configured as follows: 1= ground, 2= +, 3= -. If
only one Input signal is available, select "Input
L". To get full power out of the system, connect
"Through L" with "Input R" via XLR cords.

2.3 Operating Speakers

• First make sure the powered cabinet is off.
CAUTION! Connect the cabinet to the mains
supply only after you are certain the local
mains voltage matches the voltage specified
on the rear panel. If you connect the system to
the wrong mains voltage, you may destroy the
electronic components of the PREMIUM PR:O
active cabinet.
• Back the Gain knobs all the way off, turning
them counterclockwise as far as they will go.
Ensure you first 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,
effects 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, first turn the Gain
knobs to the far left and switch active cabinets
off first, before switching off any connected
devices.
After you power the system up by engaging the
Power switch, a system check prompts the fan
to briefly kick on and back off again in about
five seconds. The fan is temperature-controlled,
actuating only at very high volumes and tempe-
ratures requiring cooling.
• The Power LED lights up green when the cabi-
net receives mains power.
Set the Gain Line In knob to the center or 12
o'clock position (= 0 dBV). This is the preferred
level if you have connected a mixer to the PRE-
MIUM 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
LED (red) does not light up continuously.

2.4 Settings

Adjusting volume with the Gain knob
Twist this knob to adjust microphone and line
signal levels.
CAUTION: Never tape over the plug's ground
terminal – this endangers lives!
If you hear distortion or saturated signals, first
check the signal sources and, if possible, red-
uce the output signal level there. If you cannot
adjust the level of the signal routed to the PRE-
MIUM PR:O active cabinet at the source, match
it to the power amps by backing off the Gain
knob to lower the input level.
