1.2 Connecting Cords
• 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 42–45 for illustrations of cable connections.
1.3 Operating the Cabinet
• Ensure the powered PREMIUM PR:O cabinet is switched off .
• 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, eff ects and the
like—should be switched on fi rst. Always switch on the PREMIUM PR:O
last, after you power up all connected devices, and switch it off fi rst; that
is, before you switch off all connected devices.
• When you fl ip on the Power switch, the fan will start up briefl y for a
system check and switch off after around fi ve 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 / center-
notched). 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, fi rst 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 refl ections. 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.

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.
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
The PREMIUM PR:O models PR:O 110 XD2 and PR:O 112 XD2 come with
three countersunk M8 rigging points. They lets you fl y the speaker on steel
cables or chains at inclinations from 0° up to 45°. When fl ying 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.
Tilt Brackets
The PREMIUM PR:O models PR:O 112 FD2, PR:O 115 FD2 and PR:O 115 XD2
may be fl own on a tilt bracket. These three models come with heavy-duty
4x5 mm threaded inserts in the side-mounted shell grips that serve to
attach the HK Audio TB-45N and TB-45NQ tilt brackets. (The Q model
detaches with quick-release pins.) Mounting instructions are enclosed with
the tilt brackets.
