Digital Audio Impedance Meter

The Redback Impedance Meter is an absolute necessity for all PA system installers. An impedance meter is critical foraccurately measuring low impedance loudspeaker systems, incorporating multiple speakers and crossovers, and for measuring commercial 70V or 100V line speaker systems, whichmay include many speakers with line transformers and severalhundred meters of cable. Trying to measure this type of loadis virtually impossible with a standard multimeter. The Redback® Q 2004 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.

The Redback Q2004 is the first impedance meter model to feature a rechargeable internal lithium battery, make it easy to keep the unit charged up and ready to use when you need it.
