Stage Left Audio - Bridging a QSC amplifier - YouTube

A brief tutorial on bridging an amplifier (QSC PLX). This method of bridging can apply to other current professional amplifiers as well. However, not all amplifiers support a bridged mode. A reference is made to +1 and -1 when viewing the binding posts - this references the use of Speakon connectors on the speaker side (not the amplifier side).
