The ProAudium Zircle PA/VA Impedance Meter is an essential item for anyone working with loudspeakers in commercial audio systems.

Whether installing, commissioning or fault finding, the Zircle tester enables you to check the impedance of loudspeaker lines in public address or voice alarm sound systems thereby pinpointing any cabling faults or possible loudspeaker shorts.

Unlike other impedance meters, the Zircle is unique in that it displays both the impedance AND the power on its LCD screen. This streamlines the whole process by removing the need for the user to mathematically convert the reading into watts.

A useful 1kHz tone generator is built in which can be fed through a loudspeaker circuit enabling a walk around test of the system.

Another nice benefit of this digital power & impedance meter is that it requires no set up or calibration before use unlike its analogue counterparts!

• Display shows Power (Watts) AND impedance (Ohms)
• Digital meter – no calibration required
• Battery operated for portability (PP3 included)
• Computes watts (100 V) and impedance @ 1000 Hz
• Fast processing with results in under half a second
• 5 watt (2000 Ω) to 500 watt (20 Ω) test range
• Short circuit indicator with audible warning
• One button operation
• Auto ranging – no reading errors and quick results
• Low battery indication
• Crisp backlit two line display
• Optional magnetic hanging strap
• Consistent and accurate measurements
• Complete with protective carry pouch, battery, test leads & clips

Although a standard multi-meter cannot be used to measure loudspeaker line impedances, don’t leave it at home as it is still useful for other tests in the circuit - please read the attached downloads or contact us for further information.
