Audio Impedance Meter


Redback – Q 2007 – Audio Impedance Meter – Digital

$369.00 RRP Inc GST


The Redback impedance meter is an absolute necessity for all PA system installers. An impedance meter is critical for accurately measuring low impedance loudspeaker systems, incorporating multiple speakers and crossovers, and for measuring commercial 70V or 100V line speaker systems, which may include many speakers with line transformers and several hundred meters of cable. Trying to measure this type of load is virtually impossible with a standard multimeter. The Redback® Q 2007 measures and calculates loads for both 100V and 70V line systems up to 5k Watts in power. Most impedance meters on the market display the impedance in ohms, leaving the installer to calculate the system wattage. This impedance meter for ‘dummies’ designed and manufactured by Redback calculates and displays speaker loads in watts.

An inbuilt system check mode produces a 1KHz test tone into the connected speaker line, enabling the operator to check all speakers on the line are working.
