Frequently Asked Questions - Premium PR:O 115 XD2 HK AUDIO

How to connect the Premium PR:O 115 XD2 speaker?

Use a balanced XLR or jack cable to connect your source (mixer, microphone, etc.) to the combo Input. For a Line signal, set the switch to Line; for a microphone, to Mic. Connect the supplied mains cable to the Mains socket and set the Power switch to ON.

What does the red LED on the speaker mean?

The red LED indicates limiter activation (brief flashing) or overload (steady red). If the LED stays solid red, reduce the input level via the Gain knob or the mixer. If the speaker produces no sound with solid red, the protection circuit has triggered: contact a dealer.

How to use the DuoTilt system?

The DuoTilt allows tilting the speaker on a stand. The front opening gives a 7° angle (recommended for close audience), the rear opening gives 3° (for distant audience). Insert the stand into the chosen socket to get the desired tilt.

How to set the optimal gain?

Start with the Gain knob at the center position (click at +4 dBu). Then adjust the volume from your mixer. If the sound is too low or too high, slightly adjust the gain. Avoid keeping the red LED lit continuously.

When to use Flat or Boost mode?

The Flat mode offers a linear response, ideal for live use or with subwoofers. The Boost mode enhances low frequencies (70-80 Hz) for more presence. Choose Boost if you use the speaker alone without a subwoofer.

How to disable the Auto Stand-By function?

Locate the Auto Stand-By switch on the rear panel. Set it to Off for the speaker to remain active continuously. In the On position, it goes into standby after 4 hours without a signal.

Why is the sound saturated or distorted?

First check the levels on your mixer: the LEDs should not stay in the red. Reduce the output level. If the mixer is correct, reduce the Gain knob on the speaker. Also ensure the Mic/Line switch is set to Line for a line source.

How to clean the Premium PR:O 115 XD2 speaker?

Disconnect the speaker before any cleaning. Use a dry, lint-free cloth to wipe the surface. Never use liquid or abrasive products. The front grille can be dusted with a soft vacuum cleaner.

Can I suspend the speaker?

Yes, the PR:O 115 XD2 has attachment points in the side handles for flying hardware (e.g., HK Audio TB-45N). Use only approved accessories and have a qualified installer perform the setup. Follow the safety instructions in the manual.

What minimum impedance can I connect to the Thru output?

The Thru output is a passive loop that transmits the input signal. It should not be used to connect passive speakers. Use it only to send the signal to other active speakers or a subwoofer. The load impedance on this output is not critical as it is a high-level line output.

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 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 mounting accessories) must be secured by two independent risks to prevent them from falling. Safeties must be able to accessories or parts that are loose or may become loose. Compliance with the given national regulations when using tinging, attaching, and rigging devices. Factor potential dynamic (jerk) into the equation when determining the proper size and bearing capacity of safeties.

Be sure to observe speaker stands' maximum load-bearing dry. Note that for reasons of design and construction, most or stands are approved to bear centric loads only; that is, the rers' mass has to be precisely centered and balanced. Ensure or stands are set up stably and securely. Take appropriate added res 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 mounting fixtures and loudspeakers to ensure it is properly

The operator of loudspeaker systems (fixed or portable) must regularly inspect or task 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 levels. Even prolonged exposure to seemingly harmless levels (e.g. at about 95 dBA SPL) can cause permanent hearing damage. More we recommend that everyone who is exposed to high levels produced by loudspeaker systems wears professional protection (earplugs or earmuffs).

1 Power

This is the PREMIUM PR:O powered cabinet's on/off 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:0 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:0 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:0 cabinet back up again, simply set its Power button to Off 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 Off.

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 off the sound. The overall volume is not affected.

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:0 110 XD2, PR:0 112 XD2, PR:0 115 XD2) 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 = -).

10 Mains

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

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 first. Always switch on the PREMIUM PR:0 last, after you power up all connected devices, and switch it off first; that is, before you switch off all connected devices.
• When you flip on the Power switch, the fan will start up briefly for a system check and switch off 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 / 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, 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.

-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 (PR:0 110 XD2, PR:0 112 XD2)

The PREMIUM PR:0 models PR:0 110 XD2 and PR:0 112 XD2 come 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.

Tilt Brackets (PR:0 112 FD2, PR:0 115 FD2, PR:0 115 XD2)

Technical line drawing of a mechanical device with no visible text or symbols

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.

2 PREMIUM PR:O Self-powered Subwoofers

PR:0 118 SUB D2 • PR:0 210 SUB D2

2.1 Control Features

1 Line Out Mid/High L/R

Two electronically balanced XLR outputs for connecting PREMIUM PR:0 mid/ high units (pin 1 = ground, 2 = +, 3 = -).

② Input L/R

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

③ Thru L/R

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 cutoff frequency of the subwoofer with a range of 75 to 150 Hz. The best cutoff frequency for the given application depends on the surroundings and satellite, so you will have to experiment.

Note: If you set the cutoff 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 cutoff 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 in combination with a PREMIUM PR:O active cabinet.

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.

7 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 briefl y fl ashes 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.

This is the PREMIUM PR:0 powered cabinet's on/off button. The signal LED lights up green to indicate the cab is powered up.

Mains

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..

Auto Stand-by (PR:0 118 Sub D2 only)

The built-in amp switches to standby mode (Consumption around 0.5 watts) when the button is set to „On“ and the unit does not receive a signal for 180 minutes. To power the subwoofer back up again, simply set its Power button to „Off“ for five seconds and then back to On. The subwoofer will remain up and running if you disable Auto Stand-by by setting this button to „Off“.

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

• Ensure the powered PREMIUM PR:O cabinet is switched off.
• Back the Gain knobs all the way off, 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, effects and so forth. Always connect PREMIUM PR:0 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 off first, before switching off 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 off 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:0 active cabinet at the source, match it to the power amps by backing off 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:0 active cabinets have sufficient 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:0 active enclosures. Using two different ground circuits can create a ground loop. To prevent this problem, always connect PREMIUM PR:0 active enclosures and the mixing console to the same electrical circuit; that is, the same phase!

5 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 off the volume at the mixer.
• If the LED displays on your mixer are in the green, back off the PREMIUM PR:0 active cabinet's Gain knob.
• Observe the Limiter/Status LED on the PREMIUM PR:0 active enclosure's control panel. It may light up red, but only intermittently. The light may not illuminate continuously red. If it does, turn down the Gain knob.
