LS4600 [ 6 CH SPEAKER LINE SURVEILLANCE PANEL (VER.02) ]
________________________________________________________________________________________
INTRODUCTION
LS4600 monitors the condition of speaker line for faults such as ground leakage, short circuit and open circuit and open circuit. It employs impedance measurement method with detection tone, and this would eliminate the use of blocking capacitors and resistors in the speaker network. Upon detection of flaws, it would provide fault alert via LED indications and buzzer.
This improved LS4600 (Ver.02) has wider detection range as compared to its predecessor, from 10 Ohm to 10 K Ohm. Other added features included are two level of detection setup - basic and advance, circuit fault disconnection option, improved accuracy and stability.
