Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat
Do not defeat the safety purpose of the polarized or grounding plug. A polarized plug has two blades one wider than the other. A grounding plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.
Only use attachments/accessories specified by the manufacturer.
Protect the power cord from being walked on or pinched particularly at the plugs, convenience receptacles, and at the point where they exit from the apparatus.
Clean the product only with a soft and dry fabric. Never use liquid cleaning products, as this may damage the product’s cosmetic surfaces.
Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for long periods.
Avoid placing the product in a location under direct sunlight or near any appliance that generates UV (Ultra Violet) light, as this may change the product’s surface finish and cause a color change.
Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
CAUTION: These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.
WARNING: Only use attachments/accessories specified or provided by the manufacturer (such as the exclusive supply adapter, battery, etc.).
Before turning the power on or off for all devices, set all volume levels to a minimum.
This apparatus is intended for professional use.
Installation and commissioning may only be carried out by qualified and authorized personnel.
Use only speaker cables for connecting speakers to the speaker terminals.
Be sure to observe the amplifier’s rated load impedance particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier’s rated range can damage the apparatus.
K-array cannot be held responsible for damage caused by improper use of the loudspeakers.
K-array will not shoulder any responsibilities for products modified without prior authorization.

The Kayman-KY102-EBS steerable line array loudspeaker has been designed to provide an advanced solution to control the emission and directivity of the sound source.
The Electronic Beam Steering integration with PAT – Pure Array Technology –, combines accuracy and even coverage with maximum control over directivity of the Kayman-KY102-EBS line array where each of the eight woofers can be independently processed through FIR filters.
The dynamic control and manipulation of the sound beam employing a K-array Kommander-KA power amplifier with EBS DSP allows to precise aim of the emission of the line array loudspeaker over the desired listening area.
This is particularly essential in environments where the risk of sound leaks or dispersion is high, such as reflective halls where traditional speaker tilting is restricted.

Unpacking

Each K-array loudspeaker is built to the highest standard and thoroughly inspected before leaving the factory. Upon arrival, carefully inspect the shipping carton, then examine and test your new amplifier. If you find any damage, immediately notify the shipping company. Check that the following parts are supplied with the product.

A. 1x Kayman-KY102-EBS with built-in 5 m (16.4 ft) signal cable.

Electronic Beam Steering

Traditional line array loudspeakers are appreciated for their narrow on-axis directivity: the Kayman-KY102-EBS can break this paradigm with no need for any specific mechanical arrangement.
The Kayman-KY102-EBS features eight 4” drivers that can be directly and independently driven by eight separated amplifier channels. The Kommander-KA18 is the dedicated K-array 8-channel audio power amplifier with DSP designed to perfectly match with the Kayman-KY102-EBS’ eight 4” drivers.
By freely updating the Kommander-KA18 DSP firmware to the EBS version, it is possible to modify the natural emission of the line array loudspeaker by steering the sound beam off-axis.
This feature can be used to overcome some limitations of the physical installation of the loudspeaker allowing to modify of the directivity of the loudspeaker according to the actual listening configuration.
The K-framework3 is the all-in-one software providing both the acoustical simulations of the loudspeakers coverage and fine-tuning of a sound reinforcement system.
Thanks to the K-framework3, designing, configuring, and tuning a sound reinforcement system composed of Kommander-KA18 amplifiers with EBS DSP and Kayman-KY102-EBS steerable loudspeakers can be easily accomplished in a few simple steps.

Wiring

A single Kayman-KY102-EBS steerable line array element shall be driven by a single Kommander‑KA18 amplifier with EBS DSP. The amplifier output channels 1 to 8 shall be matched with the loudspeaker woofers 1 to 8, where woofer 1 is the top transducer and woofer 8 is the bottom transducer.

The Kayman-KY102-EBS is provided with a built-in 5 m (16.4 ft) long multicore cable.
The cable ends with eight pairs of strands. Each pair of strands is connected to the wiring terminals of a single woofer. Each strand is labeled according to its termination.

Strand Label	Polarity	Woofer
W1–	COLD (–)	1
W1+	HOT (+)
W2–	COLD (–)	2
W2+	HOT (+)
W3–	COLD (–)	3
W3+	HOT (+)
W4–	COLD (–)	4
W4+	HOT (+)
W5–	COLD (–)	5
W5+	HOT (+)
W6–	COLD (–)	6
W6+	HOT (+)
W7–	COLD (–)	7
W7+	HOT (+)
W8–	COLD (–)	8
W8-	HOT (+)

In order to drive the Kayman-KY102-EBS transducers independently, every pair of strands shall be connected to a single Kommander-KA18 amplifier channel. A 16-wire multicore cable shall be used to connect the Kayman- KY102-EBS loudspeaker to the Kommander-KA18 amplifier. At the amplifier end, the strands of the multicore cables shall be terminated with the PC 4/ 4-ST-7,62 flying connectors provided with the Kommander-KA18 amplifier. The wiring schematics shall guarantee the proper loudspeaker woofer to amplifier channel matching.

Wire Gauge

For up to 30 m (almost 100 ft) of cable run a multicore cable with 16 conductors 0,75 mm2 cross-section (18 AWG) can be used.
For longer cable runs the power loss shall be taken into account; consider using cables with a large cross-section to limit power loss. For longer runs up 150 m (490 ft) the suggested minimum gauge is 4 mm2(12 AWG) yielding about 3 dB loss.

Updating EBS DSP

The Kommander-KA18 amplifier firmware can be updated to EBS using the K-Monitor software version 1.4.4 or higher.

A. Connect the computer running the K-Monitor software to the same network comprising the Kommander-KA18 amplifier.
B. Launch the software and let it discover the amplifier.
C. Click on the amplifier icon in the left sidebar: the main window will show the amplifier parameters.
D. Click on the “double arrow” icon button to start the firmware update.
