Description

The Digital Impedance Bridge tells you how many watts the speakers draw on both 25 and 70V speaker lines. Simply turn it on, connect it to the speaker’s line (not to the amplifier!), and read the watts the speakers draw right off the LCD display.

It also puts a tone over the speakers (without the amplifier connected), which makes finding a bad speaker quicker.

The Digital Impedance Bridge lets you adjust the speaker and horn taps to match what the amplifier can put out. That's useful in a new installation where the speaker could actually use more watts than it says, but critical when you're repairing a system that's blowing the fuse or circuit breaker in the amplifier (or blowing up the amplifier itself!).

Amplifiers often sound distorted for a while when they're overloaded before they blow up.

Includes Case and Leads.
