1. INTRODUCTION

The KR systems are integrated, self-powered speaker systems featuring mid-high line array elements matched to powered subwoofers. All systems feature two channels of Class D amplification housed in the subwoofer(s). The rear panel provides input for 2 balanced line signals and a digital signal in AES/ EBU protocol. And with the K-dante accessory, the system can be used in a Dante network.

An integrated touch screen provides intuitive managing and editing of powerful DSP controlling: input and output levels, In/Out routing, subwoofer delay up to 12 ms, Speakon output to the mid-high element with delay of up to 12 ms, and overall system delay up to 330 ms. All DSP functions, including EQ can be controlled with remote managing software via USB or RS485, again, conveniently on a standard XLR.

The Mark I version is the newest version of the KR102, KR202 and KR402 systems, featuring new auto range amplifiers, new codecs that reduce the signal/noise ratio, a 5v dc power connector on the rear amplifier panel and enhanced functionality for creating presets. The output AES/EBU is now latency-free (through) and other updates include a larger LCD screen (2.8”), the removal of the e-fun connector and a new paint job for the mid-high elements. All these features are included in the KR802 as well.

All KR systems are designed by the K-array R&D department and custom made under the K-array quality control system.

8. AMPLIFIER

8.1 AC POWER

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

Before applying AC to any K-array self-powered speaker, ensure the voltage potential difference between neutral and earth

ground is less than 5 VAC.

8.2 VOLTAGE REQUIREMENTS

The KMT12, KMT18 and KMT21’s switching power supply accommodates AC mains operating at either 115 V or 230 V. The amplifier will continue to operate safely, without interruption, provided that the AC voltage remains within this nominal range (operating range 90 - 135 V or 190 - 250 V) at 50 to 60 Hz.

The KMT12 Mark I, KMT18 Mark I, KMT21 Mark I and KMT218’s auto-range power supply feature allows the amplifier unit to operate safely and without audio discontinuity when the AC voltage stays within a nominal range of 100 - 240 V (operating range 85 - 265 V) at 50 to 60 Hz.

Please verify that your AC main connections are capable of satisfying the power rating for the device.

CAUTION: Do not connect the system to AC mains power exceeding 265 V. Doing so will cause significant damage to the

device and create serious risk for users!

8.3 CURRENT REQUIREMENTS

The amplifier presents a dynamic load to the AC mains, drawing additional current as operating levels increase. Different cables and circuit breakers heat up at varying rates, so it is essential to understand current ratings and how they correspond to circuit breaker and cable specifications. Maximum continuous RMS current - measured over a period of at least ten seconds - is used to calculate the temperature increase in cables, which drives the proper size and gauge cable and rating for slow-reacting thermal breakers. Maximum burst RMS current - measured over a period of approximately one second - is used to select the rating for fast-reacting magnetic breakers.

For best performance, voltage drops should not exceed 10% at 100 V or 10% at 230 V. The minimum electrical service amperage required by a K-array loudspeakers system is the sum of their maximum continuous RMS current. K-array recommends allowing an additional 30% above the minimum amperage to prevent peak voltage drops at the service entry.

KR PORTABLE SYSTEM Ver. 1.0

8.4 PROTECTION CIRCUITRY

Both the power supply and the amplifier sections are equipped with several protection circuits. The power supply protections aim to isolate a faulty section in the electrical power system from the rest of the device in order to prevent the furtherance of the fault and limit device damage. They comprise of overcurrent, overvoltage and thermal protections.

Amplifier protections are triggered by audio signal current and voltage – by comparing input and output – and NTC (Negative Temperature Coefficient) thermistors. A Peak Current Shut Down and a Temperature Protection Limiter protect the output stage.

High frequency stationary signals, like steady sinusoidal signals – improperly referred to as continuous or permanent signals – with high amplitude tend to stress the amplifier section of the modules as well as the loudspeaker’s voice coils. When a high frequency stationary loud signal is fed into the amplifier, a dedicated Limiter confines its mean current depending on its level and frequency.
