R&D Background

0 Poweramplifieristhe drivingsource ofthespeakersystem.It needstorun continuouslyfor a long time under high voltage, high power and high temperature. It is the main energy consuming device of the sound amplification system, which directly affects the sound quality,energyconsumption and reliabilityofthesound amplification system.

O Therefore, high-quality and efficient network monitoring amplifier has been widely concerned at domestic and abroad. Although the digital amplifier developed in recent yearshas 90% high powerconversionefficiency,ithasnotbeen widelyused becauseoflow bassenergy,impure waveformand high price.

O The energy efficiency of traditional power amplifiers is usually around 50% (class AB amplification, 8 ohm speaker load), and the energy efficiency will also decrease with the reduction of the load impedance, which not only generates heat and consumes a lot of energy, but also affects the reliability of the long-term operation of the amplifier. Therefore,ahot backup digital poweramplifiersystem has been developed, which adopts the international advanced and original nanocrystalline full-bridge switching power supply circuit,the independent module 8-layer board layout, and the built-in "t" type LC power filter technology development, which is specially developed for the protection of important conferences and venues. , military and other special places sound reinforcement system, etc. The technical system is safer and more reliable than the conventionalsoundreinforcementsystem.

Introduction

O AK260Intelligent Controllerisa sequential powersupply which can provide 20000w in and out, with built-in T-filter, purifying power supply and strong anti-interference. The AK260 smart controller can automatically detect and monitor the operation status of the power amplifier. It can recognize four kinds of signals: LF, MF, HF orfull range frequency. If AK260 detects that there is no signal output from an amplifier, it will automatically switch the backup amplifier to the position of the faulty main amplifier to achieve seamless and automaticswitch.Ensuresoundamplificationsystemrunsstablyandreliablywithoutloss.

Innovation

0 Asthe core ofthe whole intelligent hot backup system, the AK260 intelligent controllercan monitor the operation status of each amplifier. If abnormalities are found, the backup amplifier can be automatically switched to the position of the main amplifier in failure, which can achieveseamlessautomaticswitching.
