1. INTRODUCTION

The KB1 fits perfectly into the K-array brand by combining innovation and quality.

What makes it special is that it is immediately recognizable as a product which was developed in an environment (K-array) which is orientated towards the “professional” sector.

Some of the features found on-board the KB1 are unique in the entire panorama of products on offer, and are the same as those used in stage set up during concerts

(e.g. the medium-high speaker has the ability to electronically vary the height of sound diffusion).

The completeness of the instrumentation, for example the capacity to load different presets simply and at any time from a PC, the control of entry sound through an integrated professional digital mixer, and the ability to electronically modify the extent and the coverage of the sound vertically, make the KB1 versatile and applicable to any situation with notable levels of quality.

The materials are the same as those used in high calibre concert systems: steel, aluminium and wood. These high-quality materials are normally used in professional standard products.

3. ADVANTAGES FOR MUSICIANS

3.1 The musician and his/her sound

PCs are becoming ever more part of the musician’s personal equipment and with a

KB1 you become the true craftsman of your own sound. You can connect to your own amplification system while interacting directly with digital sound processors mounted on board. This is an uncomplicated way of designing the sound according to your personal tastes and preferences. The digital mixer with 4 inputs allows those with more than one instrument to produce a unified sound, either with a sound technician or directly to the public, created according to the musician’s personal artistic choices.

Input levels, EQ parameters on each input channel, multi-effects with 16 presets, compressors, regulation of an auxiliary output, a headphones output, a main output channel and parameter filters for equalizing the speaker on output, are all instruments you can find on board the main integrated mixer.

3.2 Transportability and easy-handing

Compactness, light-weight design and transportability mark the KB1, ensuring its seamless integration into a musician’s kit. In fact one of the KB1’s strengths is its easy-handling. The unit is equipped with materials and case which enable you to load and unload easily, even with a small car, such as a hatchback. The sub is protected by a padded cover designed to insulate the sub from bumps and scratching. This allows the KB1 to be transported comfortably together with all the cables needed for set up.

The medium-high speaker is contained in a hard case, which ensures it cannot be damaged in transit.

The designers of the KB1 have chosen materials which are commonly used in professional quality products. Plastic materials have been deliberately avoided, in order to give the system the resilience required for professional use. Wood, steel and aluminium have been chosen to forge the BlueLine; perfectly matching the characteristic quality of the K-array brand.

3.3 Set up, configuration, performance

Standard connections like speakon, XLR and jack guarantee that the cabling is easy and familiar to the user. In this way, even in an emergency, the cables provided in the packaging at the moment of purchase can easily be substituted for commonly available cables of the same type.

rev. A

KB1

A 12” subwoofer for bass and eight 3” loudspeakers for medium-high frequencies guarantee elevated performance, preserving the timbre quality of the instruments and voices. Configuration using a central pole for the medium-highs makes the KB1 a true line-array from the point of view of sound emission. It projects sound pressure which remains constant even at distance, and which covers the listening area with great precision and uniformity.

The presets which process the output sound enable sound optimization for numerous types of use and varied environments.

All of the characteristics which have been described so far, not to mention the facility for modular integration of several KB1s as required, make the system an extremely versatile tool, adaptable as monitor, amplification for solo-artists and, if doubled-up, as the main stereo PA system for an event. A special rubber support accessory, which comes with the kit, enables the system to be used as a monitor or as a front fill, by laying the medium-high unit horizontally and varying the inclination.

4. UNPACKING

Each K-array device is built to the highest standard and thoroughly inspected before leaving the factory. Carefully inspect the shipping carton, then examine and test your new loudspeaker. If you find any damage immediately notify the shipping company.

Only the consignee may institute a claim stages in the system’s electronic equipment.

6. SAFETY INSTRUCTIONS

WARNING

• It is important that loudspeaker systems are used in a safe manner.

• Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90 dB if people are exposed for an extended period.

• Never stand close to loudspeakers driven at high volume.

• Suspending the system should only be done by qualified personnel following safe rigging practices. Secure fixings to the building structure are vital. Seek help from architects, structural engineers or other specialists if in any doubt.

• Do not operate the speaker for an extended period of time with sound distortion.

This is an indication of malfunction, which in turn can generate heat and result in a fire.

• Only connect the power supply to an appropriate power adapter.

• Do not install the speaker in wet or humid locations without using weather protection.

• Do not allow water or any foreign object to get inside the speaker. Do not put objects containing liquid on, or near, the unit.

• To reduce the risk of overheating the amplifier, avoid exposing it to direct sunlight.

Do not install the unit near heat emitting appliances, such as a room heater or stove.

• No naked flame sources such as lighted candles should be placed near the device.

• The speaker should be placed so that its location does not interfere with its proper cooling.

• Do not attempt to disassemble the unit. The unit contains no user-serviceable parts. Repairs should only be performed by factory trained service personnel.

• Be sure that the adapter has the correct voltage value.

8. POWER AND VOLTAGE REQUIREMENTS

8.1 AC Power connector

The amplifier module and the rest of the audio equipment connected to it (mixing consoles, processors, etc.) must be connected to the AC power distribution in the correct way, preserving AC line polarity and connecting earth ground, so that all grounding points are connected to a single node or common point using the same cable gauge as the neutral and line(s) cables. Bad grounding connections between speakers and the rest of the audio system may produce noise, hum and/ or serious damage to the input/output stages in the system’s electronic equipment.

Before applying AC to any K-array self-powered speaker, be sure that the voltage potential difference between neutral and earth ground is less than 5 VAC.

8.2 Voltage requirement

KB1 operates safely and without audio discontinuity if the AC voltage stays within both 85-132 V and 170-264 V , at 50 or 60 Hz.

Verify that your mains connection satisfies the power ratings of the device.

CAUTION

Connecting the system to an AC power mains with a voltage exceeding 270V will cause significant damage to the device and create a serious risk for users!

Right side in a stereo configuration.

B) CH1 XLR balanced (cannon) phantom powered input.

C) CH1 XLR link output. This is a direct physical parallel link ONLY to CH1

XLR input.

We advise against connecting any signal to the KB1 serving as Right Side in the stereo configuration, other than the XLR coming from the DI Out / Out R output of the main KB1 (serving as Left Side of the stereo). In a stereo configuration all signals must be connected to the

Left Side module, where all DSP functions are active and DIRECT IN is OFF.

10. CONNECTOR WIRING

The KB1 receives DC power from a 3-pin DVE connector on the back panel. The white PowerCon connector is a parallel OUTPUT for supplying power to other devices (max 5A @110V supported). When AC power is applied to the speaker, the auto-range power supply automatically selects the correct operating voltage.

To create your own power cables, please use the following wiring diagrams:
