technical specifications
LS4600 monitors the condition of speaker line for faults such as ground
leakage, short 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 ( version 2 ) has wider detection range as compared to
its predecessor, from 10 Ohm to 10 KOhm. Other added features included are
two level of detection setup - basic and advance, circuit fault disconnection
option, improved accuracy and stability.
6 channel speaker line monitoring and expandable
Basic and Advance level of detection setup
Detection of faulty cable and speaker in individual zone or circuit
Impedance measurement method - no capacitor coupling
required and cable branching allowed.
Faulty circuit disconnection option
Built in impedance meter, range within 10 Ohm to 10 KOhm
LCD display to facilitate system setup, measurement and
monitoring
Fault alert with LED indicators and switchable buzzer
Detection test interval setting from 1 min to 48 hours
Short burst test signal, minimizing interruption to PA operation
User setting for detection sensitivity for open, short and leakage
Aux 24V DC output for volume controller overriding during
testing mode
