General applications
The Python-KP family includes line array speakers with pure array carachiteristics – designed for mid/high frequencies, ensuring optimal reproduction in those ranges. To reproduce low frequencies and extend the overall frequency response of the system, it is necessary to pair them with dedicated subwoofers from the Thunder-KS family. This approach allows for the creation of a scalable and adaptable audio system suitable for various applications in the audio industry, ranging from installations to live events. It’s important to consider this when approaching the installation of the speaker and the overall system.

Loudspeakers Presets
Natural
Full-Range
Each Python-KP can be used with natural preset, with a dedicated frequency response and crossover frequency when paired with a subwoofer, or in full- range mode. The Full-range preset is designed to extend the speaker’s frequency response in the mid-to-low range and is particularly suitable for applications where the use of a subwoofer may be limited due to space constraints, different requirements, or to contribute to low-frequency extension with precision and efficiency.

Positioning
The Python-KP loudspeakers perform best when positioned on a planar surface such as a wall.
Different accessories can be purchased to mount loudspeakers on walls, providing flexibility to tilt the speakers for optimal coverage of the listening area.
They can also be installed in a standing position, using dedicated joining accessories and a base, always considering the correct coverage of the listening area.
Find the proper installation height, aiming the loudspeaker at the listening position.

We suggest the following configurations:

Spot & Flood Coverage Switch
To achieve optimal coverage in a specific listening area for diverse applications, the Python-KP I loudspeakers come equipped with a dedicated switch for selecting vertical dispersion:
Spot coverage – the speaker is set to spot by default.

Sets a narrower vertical diffusion angle of 10°.

Spot coverage is recommended for long throw applications. In array configuration set the coverage to spot.
In multi-speaker applications, set coverage to Spot.

Flood coverage
Sets a wide vertical diffusion angle of 45°.

Flood coverage is suggested for single speakers in diffused short throw applications, to obtain maximum diffusion.

Wiring
For easy connectivity and link, the Python-KP I Loudspeakers feature a SpeakON NL4 connector. The internal wiring is shown in the picture below:

Terminals 1+ 1- are connected. 2+ 2- are passing trough.

Impedance selection

It is possible to set the speaker at high or low impedance using the dedicated switch located on the rear panel.

| LOW-Z| HIGH-Z
---|---|---
Python-KP52 I| 8 Ω| 32 Ω
Python-KP102 I| 4 Ω| 16 Ω

Amplifier Channel Matching

The number of Python-KP I that can be connected in parallel to the same amplifier channel depends on the loudspeaker model, loudspeaker impedance and amplifier power.

• Always check the loudspeaker impedance before connecting the amplifier.

The parallel connection lowers the total load impedance: caution must be taken to maintain the load impedance of the paralleled loudspeakers above the amplifier’s minimum loading impedance.
Please refer to the Amplifier-to-Speaker matching table available on the K-array website for details about the maximum number of loudspeakers that can be driven by a single amplifier channel.

Before driving the loudspeakers
ensure to load the proper loudspeaker factory preset on Kommander-KA amplifier.

Before connecting the loudspeaker cable to the amplifier:

• ensure the loudspeaker impedance matches the amplifier channel rated load impedance, especially when connecting multiple loudspeakers in parallel;
• load the dedicated loudspeaker factory preset on the amplifier DSP.

Mounting and rigging accessories
