The speaker line supervisory panel is a highly efficient 10 channels speaker line monitoring system. It is able to detect individual speaker line impedance condition that displays status by indicating short - red, open – yellow, normal -green on the 10 LEDs. The LED indicates measurement and shown no speaker is connected. The impedance measured from 20Ω to 10KΩ. Each channel can handle speaker load of 1W to 500W. In the case of speaker line is short circuit, the output will isolate and protect the amplifier from damage. There are 10 individual dry contacts control out that allow the attenuator to be bypass during speaker measurement. A fault out allows to connect to other monitoring device.
The front panel shall include time schedule checks of 1min, 1 hour, 12 hours, 24 hours and OFF. There are buttons for lamp test, calibrate, measure, Buzzer bypass and reset. Front panel with a power indicator, 10 individuals bypass channel OFF switch that allow speaker line check to be bypass.
The speaker line supervisory panel shall be capable of operation from a 24VDC power at 1 Ampere.
