K Series Network Active Loudspeaker is suitable for 110V AC & 220V AC.
Details
1) K12: two-way, 12” woofer + 44T tweeter
2) K15: three –way, 15” woofer + 75T mediant + 44T tweeter
3) K15M: two –way, 15” woofer + 44T tweeter
4) K30: three –way, 2*15” woofer + 75T mediant + 44T tweeter
5) K18: 18” subwoofer
6) It adopts CobraNet technology, with backup analogue input & CobraNet input.
7) Users can control and monitor the working temperature, loading, voltage and current of the loudspeaker remotely by PC, and achieve gains control & long distance power on and off .
8) By using one CAT5 line and RJ45 connectors, audio transmitting, controlling and monitoring can be achieved, very easy for installing and operating.
9) The mid-high and woofer is respectively driven by class D amps.
10) With complete protection(short-circuit protection, over current protection, over and under voltage protection, DC protection, power compression, temperature compression, long time power output limit, clipping limit)
11) K series network active loudspeakers are based on switching technology and auto control technology that has been used for over 40 years. The switching technology provides high reliability, small size, low weight and high efficiency. A PMC converter works as a high frequency sampler, converting the variable amplitude (audio) signal into an impulse sequence with average value equal to the audio input. The loudspeaker uses very high frequency conversion rate to obtain high performances.
12) Open choice of 110V±20%/220V±20% power supply.
13) Independent MCU control, independently running without computer.
14) User can control every channel independently.
15) All setup parameters can be stored in the memorizer.
16) Firmware is updatable via RS232 port.
17) Redundant network connection
