Premium Pr:o Passive 1.7
8
1 hligning Cabinets
with Duogilt™
The nomel integrated DuoTilt™ pole mount
allows sound energy to be utilized far more
efficientlyU With two angles of tilt to choose
from, 3° and 7°, the enclosure can be aimed
directly at the audienceU The cabinet is
stabilized at its center of gramity – no wobbling,
unwanted tilting, or unintentional turningU
Your choice of DuoTilt™ angle – 3° or 7° –
depends on the required speaker height and
the size of the roomU If you set mid/high units
on fully extended tripods or mounting poles,
select 7° to minimize ceiling reflectionsU
If you want to address an audience where
more listeners are farther away from the
speakers, use the HK AUDIO DuoTilt™ at the
3° angleU
Mono Tilt 3™ (PR:O 8) offers one angle of tiltU
2 Connecting Compo-
nents and Speakers
HK AUDIO speaker cords with a diameter
of 2x2U5 sqU mm are recommended for
connecting cabinets, power amps or powered
mixing consolesU Cords are amailable in the
following lengths:
1U LSC 3, item noU: 193283, 3 m
2U LSC 7, item noU: 193263, 7 m
3U LSC 15, item noU: 193323, 15 m
Recommended Amplifier Power
Output
Connect amps rated from 600 W @ 4 Ω RMS
to 800 W RMS @ 4 Ω per amp channel to
power the PREMIUM PR:O cabinetsU To hame
enough headroom amailable for dynamic
musical signals, the power amp should delimer
peak performance of at least 1,200 W @ 4 Ω
per channelU
Note: An electrical connection between the
cord and input jack is not established until
the Speakon connector locks into place.
Twist the Speakon connector clock wise until
it engages.
2.1 PR:O 8 / 10 X / 12 / 15 / 15 X
in Fullrange Mode
Connect the speaker output from the powered
mixer or power amp to the input (IN) of the
PR:O 8, PR:O 10 X, PR:O 12, PR:O 15 and
PR:O 15 X full-range speaker cabinetU

2.2 PR:O 8 / 10 X / 12 / 15 / 15 X
in Satellite Mode with the
PR:O 18 S or the
PR:O 210 S
First connect the speaker output of the
powered mixer or power amp to the
subwoofer’s input, and then connect the
subwoofer’s SATELLITE OUT to the
PR:O 8, PR:O 10 X, PR:O 12, PR:O 15 and
PR:O 15 X full-range cabinet’s input (IN)U

Note: The nominal impedance of systems
consisting of a combination of PR:O 18/210
S and PR:O 8, PR:O 10 X, PR:O 12, PR:O 15
and PR:O 15 X cabinets is 4 ohms!
2.3 PR:O 10 X, PR:O 12 M and
PR:O 15 X
Monitor Amp
Connect the monitor power amp’s speaker
output to the PR:O 10 X, PR:O 12 M und
PR:O 15 X monitor’s input (IN)U Depending on
the type of power amp or powered mixer that
you are using, semeral PR:O 10 X, PR:O 12 M
und PR:O 15 X monitors can be connected in
parallel to one power amp channelU
Poweramp
Note:
• When two PR:O 10 X, PR:O 12 M and
PR:O 15 X monitors are -connected in
parallel, omerall impedance is 4 ohmsU
• When three PR:O 10 X, PR:O 12 M and
PR:O 15 X monitors are connected in
parallel, omerall impedance is 2U7 ohmsU
• When four PR:O 10 X, PR:O 12 M and
PR:O 15 X monitors are connected in
parallel, omerall impedance is 2 ohmsU
Caution: Do not allow the overall nominal
impedance of the connected monitors to fall
below the power amp channel’s minimum
impedance! If it does, you risk destroying
the power amp!
3 groubleshooting
All speaker cords are connected, but no
sound is audible!
1 Check if the power amp is switched on
and the mixing console is connected to the
power ampU
2 Check if the Speakon connectors that are
plugged into the input jacks are locked into
placeU
Twist the connector clockwise until it
engagesU
You have set up a satellite system and the
mid/high units are working fine but no low-
end signal is heard from the subwoofers!
1 Check if the PR:O 8, PR:O 10 X, PR:O 12,
PR:O 15 or PR:O 15 X full-range cabinets
are connected to the subwoofer’s SATELLITE
OUTU Be sure to connect the cords in the
proper sequence! First connect the speaker
output of the powered mixer or power amp
to the subwoofer’s input, and then connect
the subwoofer’s SATELLITE OUT to the
PR:O 8, PR:O 10 X, PR:O 12, PR:O 15 or
PR:O 15 X fullrange cabinet’s input (IN)U
