Read before connecting!
This product has been built by the manufacturer in accordance with IEC 62368-1 and left the factory in safe working order. To maintain this condition and ensure non-risk operation, the user must follow the advice and warning comments found in the operating instructions. If this product shall be used in vehicles, ships, or aircraft or at altitudes exceeding 2000 m above sea level, take care of the relevant safety regulations which may exceed the IEC 62368-1 requirement. WARNING: To prevent the risk of fire and shock hazards, do not expose this appliance to moisture or rain. Do not open the case – no user- serviceable parts inside. Refer service to qualified service personnel.

This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure – voltage that may be sufficient to constitute a risk of shock.
This symbol, wherever it appears, alerts you to the presence of externally accessible hazardous voltage. External wiring connected to any terminal marked with this symbol must be a “ready-made cable” complying with the manufacturer’s recommendations or must be wiring installed by instructed persons only.
This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read the manual.
****This symbol, wherever it appears, tells you: Take care! Hot surface! To prevent burns you must not touch them.
All electrical and electronic products including batteries should be disposed of separately from the municipal waste stream via designated collection facilities appointed by the government or the local authorities.
Read these instructions. Keep these instructions. Follow all warnings and instructions marked on the product and in this manual.

General Notes on Safety for Loudspeaker Systems

Mounting systems may only be used for those loudspeaker systems authorized by the manufacturer and only with the mounting accessories specified by the manufacturer in the installation instructions. Read and heed the manufacturer’s installation instructions. The indicated load-bearing capacity cannot be guaranteed and the manufacturer will not be liable for damages in the event of improper installation or the use of unauthorized mounting accessories.
The system’s load-bearing capacity cannot be guaranteed and the manufacturer will not be liable for damages in the event that loudspeakers, mounting accessories, and connecting and attaching components are modified in any way.
Components affecting safety may only be repaired by the manufacturer or authorized agents, otherwise, the operating permit will be voided.
Installation may be performed by qualified personnel only, and then only at pick-points with sufficient load-carrying capacity and in compliance with local building regulations. Use only the mounting hardware specified by the manufacturer in the installation instructions (screws, anchors, etc.). Take all the precautions necessary to ensure bolted connections and other threaded locking devices will not loosen.
Fixed and portable installations (in this case, speakers and mounting accessories) must be secured by two independent safeties to prevent them from falling. Safeties must be able to catch accessories or parts that are loose or may become loose. Ensure compliance with the given national regulations when using connecting, attaching, and rigging devices. Factor potential dynamic forces (jerk) into the equation when determining the proper size and load- bearing capacity of safeties.
Be sure to observe the speaker stands’ maximum load-bearing capacity. Note that for reasons of design and construction, most speaker stands are approved to bear centric loads only; that is, the speakers’ mass has to be precisely centered and balanced. Ensure speaker stands are set up stably and securely. Take appropriate added measures to secure speaker stands, for example, when:

• the floor or ground surface does not provide a stable, secure base.
• they are extended to heights that impede stability.
• high wind pressure may be expected.
• there is the risk that they may be knocked over by people.

Special measures may become necessary as precautions against unsafe audience behavior. Do not set up speaker stands in evacuation routes and emergency exits. Ensure corridors are wide enough and put proper barriers and markings in place when setting speaker stands up in passageways. Mounting and dismounting are especially hazardous tasks. Use aids suitable for this purpose. Observe the given national regulations when doing so.
Wear proper protection (in particular, a helmet, gloves, and safety shoes) and use only suitable means of ascent (ladders, scaffolds, etc.) during installation. Compliance with this requirement is the sole responsibility of the company performing the installation.
WARNING! After installation, inspect the system comprised of the mounting fixtures and loudspeakers to ensure it is properly secured.
The operator of loudspeaker systems (fixed or portable) must regularly inspect or ask a third party to regularly inspect all system components in accordance with the given country’s regulations and have possible defects repaired immediately.
We also strongly recommend maintaining a logbook or the like to document all inspections.
Also, be sure to provide sufficient safety margins for the rigging points used for flown systems. Observe the given national regulations when doing so.
****Professional loudspeaker systems can produce harmful volume levels. Even prolonged exposure to seemingly harmless levels (starting at about 95 dBA SPL) can cause permanent hearing damage! Therefore we recommend that everyone who is exposed to high volume levels produced by loudspeaker systems wears professional hearing protection (earplugs or earmuffs).

Aligning Cabinets with DuoTilt™

The novel integrated DuoTilt™ pole mount allows sound energy to be utilized far more efficiently. With two angles of tilt to choose from, 3° and 7°, the enclosure can be aimed directly at the audience. The cabinet is stabilized at its center of gravity – no wobbling, unwanted tilting, or unintentional turning.
Your choice of DuoTilt™ angle – 3° or 7° – depends on the required speaker height and the size of the room. If you set mid/high units on fully extended tripods or mounting poles, select 7° to minimize ceiling reflections.

If you want to address an audience where more listeners are farther away from the speakers, use the HK Audio DuoTilt™ at the 3° angle.
Mono Tilt 3™ (PR:O 8) offers one angle of tilt.

Connecting Components and Speakers

Speaker cords with a diameter of 2×2.5 sq. mm are recommended for connecting cabinets, power amps, or powered mixing consoles.
Recommended Amplifi er Power Output
Connect amps rated from 600 W @ 4 ohms RMS to 800 W RMS @ 4ohms per amp channel to power the PREMIUM PR:O cabinets. To have enough headroom available for dynamic musical signals, the power amp should deliver a peak performance of at least 1,200 W @ 4 ohms per channel.
Note: An electrical connection between the cord and input jack is not established until the Speakon connector locks into place. Twist the Speakon connector clockwise 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 fullrange speaker cabinet.

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).

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

Connect the monitor power amp’s speaker output to the PR:O 10 X, PR:O 12 M and PR:O 15 X monitor’s input (IN). Depending on the type of power amp or powered mixer that you are using, several PR:O 10 X, PR:O 12 M and PR:O 15 X monitors can be connected in parallel to one power amp channel.

Note:

• When two PR:O 10 X, PR:O 12 M and PR:O 15 X monitors are -connected in parallel, the overall impedance is 4 ohms.
• When three PR:O 10 X, PR:O 12 M, and PR:O 15 X monitors are connected in parallel, the overall impedance is 2.7 ohms.
• When four PR:O 10 X, PR:O 12 M, and PR:O 15 X monitors are connected in parallel, the overall impedance is 2 ohms.

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!
