Power

This is the PREMIUM PR:O powered cabinet’s on/o button. The Limiter/
Status LED lights up green to indicate the cab is powered up.

●

2

Gain

Use this knob to adjust the input gain to match the incoming signal‘s level.

Adjusting volume levels with the Gain knob:

The +4 dBu (center-notched) position is the factory default setting. It is
tuned to achieve the right balance of levels between the mid/ high unit and
subwoofer. If necessary, turn the Gain knob to adjust the balance of levels
between the mid/ high unit and subwoofer(s) to suit the incoming line
signals.

●

3

Mic/Line Selector

When connecting a microphone, you can optimize the input‘s gain level by
setting this switch to Mic. This setting provides a 30 dB boost.

When connecting a line-level source such as a mixer, audio playback device,
or electronic musical instrument, set this switch to Line.

●

4

Input

Route the incoming audio signal into this electronically balanced,
combination XLR/ 6.3 mm (1/4”) input (pin 1 = ground, 2 = +, 3 = -).

●

5

Limiter/Status LED

This dual-color LED serves as a status indicator for the PREMIUM PR:O
powered cabinet (green = power on, red = limit/error). The LED briefly
flashes red to tell you the limiter is responding to signal peaks.

Caution! If the Status LED stays red during operation, the cabinet is being
overloaded. Turn down the signal level! If you are not routing a signal in
and the Status LED stays red, the system has detected a fault.

●

6

Auto Standby

PREMIUM PR:O mid/ high units have a power-saving function that can be
activated and deactivated. The power amp switches to standby mode when
the button is set to On and the unit does not receive a signal for about four
hours (consumption <0.5 watts). To power the PREMIUM PR:O cabinet
back up again, simply set its Power button to O for five seconds and then
back to On. Mid/ high units will remain up and running if you disable Auto
Standby by setting this button to O.

●

7

Tone

The Tone knob adjusts the frequency response to suit the given application.
Setting the knob to the center position defeats the filter.

Turning the Tone knob counterclockwise towards Music
attenuates by up to -6 dB a broad midrange band with a center
frequency of 2500 Hz, thereby taking the edge o the sound.
The overall volume is not aected.

Turning the Tone knob clockwise towards Speech activates a
80-to-200 Hz low-cut filter, which enhances clarity for speech
applications and reduces subsonic noise.

The X models (PR: O 10 XD, PR: O 12 XD, PR: O 15 XD) are also tuned to
minimize feedback and distortion at high volume levels.

●

8

Flat/Boost Selector

Setting this switch to Flat conjures the optimum linear
frequency response for live performances and for operation in
combination with subwoofers.

Setting this switch to Boost pumps up the bass. This boosts a
broad band of bass frequencies in the kick-drum range between
70 Hz and 80 Hz and extends the low-end response.

●

9

Thru

This passive parallel output routes the signal routed into the front-end
Input back out again (pin 1 = ground, 2 = +, 3 = -).

●

rate d c urre nt

• When operating the PREMIUM PR:O speaker cabinet as a standalone unit
or monitor without an added subwoofer, 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) or microphone
to the Input.

• When operating the cabinet in combination with PREMIUM PR:O series
powered subwoofers, use a cord equipped with XLR connectors to connect
the subwoofer‘s Line Out Mid/High to the cabinet‘s Input.

• Plug a cord equipped with XLR connectors into the Thru port to route the
input signal out again.

Go to page 18-21 for illustrations of cable connections.

1.3 Operating the Cabinet

• Ensure the PREMIUM PR:O cabinet is switched o.

Caution! Always make sure the local mains voltage matches the voltage
specified on the PREMIUM PR:O unit. You may destroy powered
cabinet‘s electronic components if you connect it to the wrong mains
voltage.

• When patching in line signals, ensure all other connected components are
switched on before powering up. The connected mixer as well as all signal
sources connected to it—keyboards, instrument amps, eects and the
like—should be switched on first. Always switch on the PREMIUM PR:O
last, after you power up all connected devices, and switch it o first; that
is, before you switch o all connected devices.

• When you flip on the Power switch, the fan will start up briefly for a
system check and switch o after around five seconds. After that, the
cabinet‘s circuitry controls the fan. It kicks in only at very high volume
levels and is regulated according to the temperature. The Status LED
lights up red during the system check. It will turn green if there is no error
and the system is getting mains power.

• The Gain knob‘s default setting is the 12 o‘clock position (+4 dBu / center­notched). This is the preferred level if you have connected a mixer to the
PREMIUM PR:O cabinet. If you plug a CD player or keyboard straight into
the cabinet, you may have to turn this knob to adjust the gain to match it
to the device‘s signal level.

Caution! Turn the Gain knob counterclockwise all the way down to the far
left when switching the input sensitivity from Line to Mic.

• If you hear distortion or clipping occurs, first check the signal sources and,
if possible, reduce the output signal level there.

1.4 Aiming the Cabinet

DuoTilt™ 3/7

The HK Audio DuoTilt 3/7 pole mount lets you align PREMIUM PR:O
cabinets vertically on a speaker stand or mounting pole to prevent or reduce
troublesome ceiling reflections. The front aperture of the HK Audio DuoTilt
provides a 7° angle, the rear aperture a 3° angle of tilt.

Rule of thumb: We recommend that you opt for the 7° angle if the audience
close by and you place cabinets at an elevated position—for example, on
stands on the stage—or if the audience is seated. This way the sound and
particularly the high frequencies are distributed more uniformly right on up
to the front face of the speakers.

–3°

–7°

If you wish to address more listeners at a greater distance from the
speakers, opt for the 3° angle on the HK Audio DuoTilt 3/7.

–3°

In both situations, you can vary the speakers‘ reach by adjusting their
height. They throw sound over a greater distance as their elevation
increases.

Rigging Points

Every PREMIUM PR:O model comes with three countersunk M8 rigging
points. They lets you fly the speaker on steel cables or chains at inclinations
from 0° up to 45°. When flying the cabinet, for example, from a truss, use
the rear rigging point to determine the degree of inclination.

We recommend using our secure AP-8 suspension points to rig the speaker
to the mounting hardware.

Two electronically balanced XLR outputs for connecting PREMIUM PR:O
mid/ high units (pin 1 = ground, 2 = +, 3 = -).

These two electronically balanced XLR / 1/4“ combi inputs accept signals
from mixing consoles (pin 1= ground, 2= +, 3= -).

●

These two parallel outputs patch incoming line signals through, for
example, to other PREMIUM PR:O active speakers or monitors
(pin 1= ground, 2= +, 3= -).

●

4

Gain Bass

This knob adjusts the input level (center position = 0 dBV). The 12 o’clock
position is the ideal starting point when operating the subwoofer in
combination with a PREMIUM PR:O active cabinet. Then you can simply
twist the knob to the left or right to cut and boost bass frequencies. If you
connect a PREMIUM PR:O satellite, first set the Gain knob to the center
detent and then adjust the level to suit the given sound reinforcement
situation.

●

5

X-Over Bass

The active crossover can serve to vary the top cuto frequency of the
subwoofer with a range of 75 to 150Hz. The best cuto frequency for the
given application depends on the surroundings and satellite, so you will
have to experiment.

Note: If you set the cuto to a frequency higher than 100 Hz, the
subwoofer will render mostly the lower frequencies of signals generated
by bass guitars, kick drums, and low-end keyboard sounds. If you set the
cuto to a frequency higher than 100 Hz, the subwoofer will also render
the lower frequencies of voices and other sound sources.

●

6

Phase

The Phase switch changes the subwoofer’s phase position to match it to
the connected satellite’s phase position (0° – 180°). Set the switch to 0°
when operating the PR:O 18 SubA in combination with a PREMIUM PR:O
active cabinet. The PR:O 210 Sub A‘s phase has to be reversed 180° to
ensure it is in phase with PREMIUM PR:O mid-/high-range units.

You may have to invert the phase for combinations with other enclosures.
If you are unsure, simply try the 180° setting. If the bass response changes
and the signal sounds weak and washed out, the phase setting is incorrect.

Limiter/Status LED

This dual-color LED serves as a status indicator for the PREMIUM PR:O
powered cabinet (green = power on, red = limit/error). The LED briefly
flashes red to tell you the limiter is responding to signal peaks.

Caution! If the Status LED stays red during operation, the cabinet is being
overloaded. Turn down the signal level! If you are not routing a signal in
and the Status LED stays red, the system has detected a fault.

Mains Input

Use the factory-included power cord to connect this socket to a wall outlet.

Note: All PREMIUM PR:O self-powered subwoofers are equipped with
V-Lock mains sockets. If you use a VOLEX locking mains cord or another
optionally available brand with the same design, you can fix the mains
cord in place to prevent accidental disconnection..

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 configured as follows: 1= ground, 2= +, 3= -.

2.3 Operating Speakers

• First make sure the powered cabinet is o.

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 o, 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, e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, first turn the Gain knobs to the far left and
switch active cabinets o first, before switching o 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 o again in about five
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.

2.4 Settings

Adjusting volume with the Gain knob

Twist this knob to adjust the line signal levels.

If you hear distortion or saturated signals, first 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 o the Gain knob to lower
the input level.

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 optimum 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 sucient
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 di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!

CAUTION: Never tape over the plug’s ground terminal - this endangers
lives!

4 Troubleshooting

The Limiter/Status LED does not light up when the power switched
on.

• Check if the power cord is plugged into the Mains input.

• Check if the mains power supply is providing current.

The Limiter/Status LED lights up red, flashing intermittently.

• The Limiter has actuated; lower the input level if necessary.

The Limiter/Status LED lights up red continuously, but no sound is
issuing from the cabinet.

• The enclosure’s protective circuit has tripped. Please contact your dealer.

The rendered music sounds distorted.

• Check your mixing console’s LED meters. They should not be constantly in
the red. If necessary, back o the volume at the mixer.

• If the LED displays on your mixer are in the green, back o the PREMIUM
PR:O active cabinet’s Gain knob.

• Observe the Limiter/Staus LED 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.
