DuoTilt™ offers 3° and 7° angles of tilt, enabling precise speaker-to-audience alignment. Acoustic interference from ceiling reflections is minimized, leaving the sound cleaner, tighter, and much more articulate. Mono Tilt 3™ (PR:O 8 A) offers one angle of tilt. Passive Crossover in Bass Systems The two PREMIUM PR:O bass bins sport a sophisti- cated cross over that sends all low-end frequencies to the woofer and all mid-range and high frequencies to the connected satellite. This frequency separation affords you the audio benefits of a truly homogenous sound system, free of the pitfalls of overlapping pha- ses that frequently plague lesser PAs. Modular System The PREMIUM PR:O Series is modular so that mid/- high units may be combined with the PR:O 18 S / PR:O 210 S bass bin at will. This modularity extends to the acoustic domain: Like every HK Audio

system, PREMIUM PR:O Series components are meticulously matched. Regardless of the PREMIUM PR:O Series configuration, you are sure to enjoy that trademark excellent HK Audio

sound! Dynamic Protective Circuitry for the High-frequency Driver PREMIUM PR:O Series mid/high units and monitors are equipped with special protective circuitry. Located in the high-frequency signal path, it limits output levels whenever the high-frequency signal level approaches the 1" driver’s overload threshold. The PREMIUM PR:O Series comprises PR:O 8, PR:O 12 and PR:O 15 fullrange speaker cabinets, PR:O 18 S and PR:O 210 S subwoofers and PR:O 10 X, PR:O 12 M and PR:O 15 X monitors.2 Connecting Components and Speakers HK Audio

speaker cords with a diameter of 2 x 2.5 sq. mm are recommended for connecting cabinets, power amps or powered mixing consoles. Cords are available in the following lengths:

Recommended Amplifier Power Output Connect amps rated from 600 W @ 4 W RMS to 800 W RMS @ 4 W per amp channel to power the PREMIUM PR:O cabinets. To have enough headroom available for dynamic musical signals, the power amp should deliver peak performance of at least 1,200 W @ 4 W 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 clock- wise until it engages.

2.1 PR:O 8, PR:O 10 X, PR:O 12, PR:O 15 and

PR:O 15 X in Full-range 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 cabinet. PREMIUM PR:O Manual 1.4 1 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 A) offers one angle of tilt.

and PR:O 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 und PR:O 15 X

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). Depending on the type of power amp or powered mixer that you are using, several PR:O 10 X, PR:O 12 M und 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, 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, 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, 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! 3 Troubleshooting 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 amp. 2 Check if the Speakon connectors that are plugged into the input jacks are locked into place. Twist the connector clockwise until it engages. 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 OUT. 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).
