To configure the two channels in a zone as a stereo pair, or as independent channels, set the Bridge/Stereo switch to ST and connect one speaker to each of the left and right pairs of binding posts (as shown below).
- Page 12 Configuring a Bridged Zone - Bridged channels may be connected to a minimum load impedance of 8 ohms. To configure the two channels in a zone as a Bridged channel, set the Bridge/Stereo switch to BR and connect one speaker to the TWO RED BINDING POSTS (as shown below). Note: The polarity markings that pertain to Bridged mode are the small “Bridge +” and “Bridge -” marked next to the two red binding posts.
