LS46oo - 6 Channel Speaker Line Surveillance Panel ( ver.2 )
Introduction
LS4600 is an essential tool for monitoring condition of speaker lines for faults such as ground leakage, short circuit and open circuit. It employs impedance measurement method with detection tone of 1 KHz and thus allows branching or looping of speaker circuits. In addition, the use of blocking capacitors and resistor at each speaker shall not be required.
The improved version has wider detection range, from 10 Ohm to 10 K Ohm. Other added features are two level of detection setup - basic and advance, circuit fault disconnection option, improved accuracy and stability.
Features
- 6 channels 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 is required and cable branching is allowed
- Faulty circuit disconnection option
- Built in impedance meter, range within 10 Ohm to 10 K Ohm
- 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
