Unique features for premium performance
Opto-Limiter
for the mid/high-range
Mid/high-range signals and low frequencies must be processed in different ways. This is why ELIAS PX is equipped with an Opto-limiter based on technology initially developed for high-end recording gear. Its soft-knee attack sounds more pleasant and incon­spicuous. The signal’s original envelope remains virtually intact, ensuring far more natural-sounding dynamic response.
• Ultra-low distortion for enhanced signal quality
• Soft-knee attack for far more harmonious and unobtrusive limiting
• The initial waveform remains uncorrupted for natural-sounding dynamic response
DynaClip™ Limiter
for the bass power amp
HK AUDIO’s DynaClip™ technology was developed specifically for enhancing low-end performance. The DynaClip™ Limiter compensates for the subwoofer’s slower initial transient response and audibly improves pulse behavior. This makes the most of low-frequency energy, and enhanced efficiency translates to more power.
• More efficient use of energy for more powerful low­end punch
• Compensates for transient response of speaker diaphragms for improved pulse behavior
• Fine-tuned for peak bass power amp performance
OFR™
Optimized Frequency Response Technology
A new technology unique to HK AUDIO, OFR™ helps this system deliver assertive yet well-balanced sound at every volume level. OFR™ corrects for the non­linear frequency response inherent in the speaker components and adapts the system’s sound output to comply with the way the human ear hears at different levels.
• Fine-tuned to each system
• Compensates for non-linear frequency response
• Adapts the system to differing volume levels
• Powerful, balanced sound in every situation
1" driver
for natural-sounding response
ELIAS PX mid/high units feature a professional-grade 1" driver engineered to deliver low-distortion performance even at threshold levels and conjure a natural-sounding sonic image. In combination with a 60° x 40° horn, it provides the focused directivity required to satisfy real-world sound reinforcement demands.
DuoTilt™
– making the most of sonic energy
The novel DuoTilt™ pole mount enables sound energy to be utilized more efficiently. It offers two angles of tilt (7.5° and 15°), allowing satellites to be aligned perfectly toward the audience. Troublesome ceiling reflections are minimized; the sonic image becomes clearer, tighter, and more focused.
Easy Setup and Handling
– less pre-gig stress
Like all HK AUDIO Active Systems, ELIAS PX was designed as a cohesive unit consisting of perfectly matched components. Painstaking effort was invested to ensure ELIAS PX can be transported easily and set up quickly. Handling and EQing couldn’t be any easier.
ELIAS PX Manual 1.0
1 ELIAS PX System Components
EPX 112 A Mid/High Unit
These enclosures are loaded with one 12" HK AUDIO Custom speaker and one 1" compression driver with a 60° x 40° CD horn. Delivering 400 W RMS, the power amp and other electronic circuitry are housed in a separate chamber.
The novel integrated HK AUDIO DuoTilt™ pole mount allows sound energy to be utilized far more efficiently. Troublesome ceiling reflections are minimized, enhancing punch and clarity. The cabinet is stabilized at its center of gravity - no wobbling or unintentional tilting or turning.
EPX 115 Sub A Subwoofer
The ELIAS PX subwoofer’s housing is split into two chambers. The front chamber serves as the speaker cabinet for the 15” direct-loaded woofer with 400­watt RMS power-handling capacity and 8-ohm nominal impedance. The power amp and other circuitry are housed in a separate compartment at the rear of the cabinet.
2 Transport
To transport the system, simply set the subwoofers on their casters and place the mid/high units onto the subwoofers with the foam rubber grille side facing down. Use original HK AUDIO‚ covers to get your system ready to handle the rigors of the road. Padded and protected against moisture, your ELIAS PX system is sure to serve you well for a long time to come.
3 Setup and Cable Connections
3.1 Aligning Speakers with DuoTilt™
The new, integral DuoTilt™ pole mount enables sound energy to be used far more efficiently. Offering two different angles of 7.5° and 15°, it lets you angle the speakers directly at the audience. DuoTilt™ stabilizes the cabinet at its center of gravity with no wobbling or unintentional tilting or turning.
Your choice of DuoTilt™ angle 7.5° or 15° depends on the required speaker height and the size of the room. The front opening of the HK Audio DuoTilt™ inclines the cabinet 7.5°, and the rear opening 15°.
If you set mid/high units on fully extended tripods or mounting poles, select 15° to minimize ceiling reflections.
If you want to address an audience where the majority of listeners are farther from the speakers, opt for 7.5°.

3.2 ELIAS PX Standard Setup
The Standard Setup comprises two ELIAS EPX A 112 mid/high units and two ELIAS EPX 115 A Sub subwoofers.
With the benefit of the ELIAS PX system’s integrated design, it takes but a few minutes to connect cables. Before you get started, make sure the mains switch is set to the OFF position. Connect cords carrying signals from your mixer (master left/right, line out, or similar circuit) to the balanced input socket of any component. It doesn’t matter which component you connect first—sub­woofer or mid/high unit. Using a standard XLR microphone cord, patch the signal from this first component’s Through output jack to the next component’s Input. Connect all subsequent components in the same manner. You can vary the number of the components freely without having to cope with compatibility, frequency separation or impedance problems, which lets you flexibly adapt the ELIAS PX system to your needs.
Connect the power cable only after you have made sure that the local mains voltage matches the voltage specified on the device. Connecting to the wrong mains voltage may destroy ELIAS PX’s electronic components.
The metal cleat below the Mains socket prevents the power cord from being pulled out accidentally. Feed the power cable through this mains cord cleat to assure the cable is relieved of undue tension.
3.2 ELIAS PX Fullrange Setup
The full-range setup comprises two ELIAS EPX 112 A mid/high units.
When operating mid/high units without subwoofers, please set the mode switch to Full-range so that the entire frequency range including low frequencies is rendered.
3.3 ELIAS PX Extension Setup
The extension setup comprises two ELIAS EPX 112 A mid/high units and four ELIAS EPX 115 Sub A subwoofers.
The procedure for setting up components and connecting cords is the same as for a standard ELIAS PX system, with the addition of two more subwoofers.
3.4 Using the Tilt Unit to Align an Extension
Setup’s Mid/High Units
Mounting the optional tilt unit couldn’t be easier: Proceed as if mounting the enclosure on a pole. Set the tilt unit with the bottom plate facing down atop the upper subwoofer, and then set the ELIAS PX mid/high unit on it in such a way that the tilt unit’s rod is inserted into one of the two holes (7.5° or 15°).

4 Connections and Control
Features
ELIAS EPX 112 A
1 Mode Switch
Operation: This switch configures the ELIAS PX mid/high unit for use in full-range mode (without subwoofers) or for use as a satellite in combination with the subwoofer.
2 Ground
Ground Lift button for separating the signal and chassis ground if humming noises occur. In the event of low-frequency hum, engage the Ground Lift switch. The ground circuit is severed when this button is pressed. If this doesn’t solve the problem, check for damage to any cord connected to ELIAS PX as well as all cords routing signals to the mixing console (see also Tips and Tricks).
3 Line In
Connecting cords: Connect cords carrying signals from your mixer (master left/right, line out, or a similar circuit) to the balanced inputs using a mic cord equipped with XLR connectors. Ensure XLR connectors are wired as follows: 1= ground, 2= +, 3= -.
4 Line Through
Connecting cords: Use this parallel output to route the incoming line signal to other components (for example, additional ELIAS PX systems or other com­ponents) via XLR cords.
5 Gain
Operation: Use this knob to adjust the input signal level. The standard setting is 0 dB at the 12 o’clock position. For weaker signal sources such as small mixers equipped with unbalanced circuitry and RCA connectors or _" jacks, you can boost levels by up to +6 dB (twist the Gain knobs to the far right).
6 Fan
This ventilator keeps the power amp modules cool. Always make sure that the fan and the vents are free of dirt and debris and that they remain unobstructed so air can circulate freely.
7 Circuit Breaker
Operation: This automatic circuit breaker serves the same purpose as a standard fuse. If it trips, first switch the system off entirely (Power switch set to OFF). Then after you have identified and fixed the problem, you can reset the circuit breaker by simply pressing it.
8 Mains Input
Connecting cords: Use the factory-included mains cord to connect this socket to a wall receptacle. Caution! Make sure the local mains voltage matches the voltage specified on the device. If you connect the system to the wrong mains voltage, you may destroy the ELIAS PX system’s electronic components.
9 Power Switch
Operation: This is the on/off switch for the active system. When engaged, the Power On LED lights up. Always switch the ELIAS PX active system on last, that is, after powering up all other components such as the mixing console, and switch it off first before powering down all other connected devices.
10 Power On LED
This LED lights up when the Power switch is set to On and the system is connected to a mains power supply.
11 Mains Cord Cleat
Secure the power cord with this cleat to prevent it from being pulled out inadvertently.
5 Tips and Tricks
1 Do not expose electronic circuitry to moisture! When you set the system up outdoors, be sure to protect it against rain. Keep soft drinks, beer and all other liquids well away from the cabinets to protect their electronic components from short-circuiting.
2 Ensure that the vents on the enclosures’ rear panels are free of dirt and the devices are ventilated properly. Otherwise, the electronic components are likely to overheat and be damaged by thermal breakdown.

3 ELIAS PX delivers optimum sound, so you should provide it with optimum input signals! 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.
4 Prevent distortion! Not only is it unpleasant to your audience’s ears, it can also damage your equip­ment. Make sure all components that are connected directly and indirectly to ELIAS PX have sufficient power ratings, and that they don’t distort as a result of operating at or beyond their respective limits. Provide an undistorted signal to the system in the first place, so that it doesn’t have to be cleaned up by backing off the system’s Gain knob.
5 Avoid ground loops! A ground loop can occur when the mixer and ELIAS PX are each connected to two different mains circuits. To prevent this problem, always connect the ELIAS PX system and the mixing console to the same electrical circuit (same phase!). If your equipment hums despite this precaution, the Ground Lift switch can be a great help.
CAUTION: Never tape over the plug’s ground terminal - this endangers lives!

Input.
2 Check if the mains power supply is providing
current.
3 Check if the house circuit breaker has tripped.
The Power On LED lights up red, but no sound is coming from the cabinets.
1 Check the cords connected to the inputs. 2 Check if the signal sources (mixer, keyboard, CD
player, etc.) are on.
3 Check if the Gain knobs are turned up.
The subwoofer’s low frequency output is weak.
1 Check the Subwoofer Gain knob’s setting
The signal sounds distorted.
1 Check the LED displays on your mixer. Ensure they
are not constantly in the red. If necessary, back off the volume at the mixer.
2 If the LED displays on your mixer are in the green,
turn ELIAS PX’s Gain knobs to reduce the input level.
Annoying hum
1 Check the cords connecting the signal source to
ELIAS PX. Replace damaged cords.
2 If you cannot pinpoint the cause of the hum, press
the Ground Lift switch. This should remedy the problem in most cases.
