Following are the definitions of key terms used in your owner’s reference manual. 

A method of linking two amplifier channels by distributing the speaker load between the 
positive binding posts. Bridging the channels quadruples the power rating at 8 Ohms. 
Bridged configurations should not be used with loads under 4 Ohms. 

An internal configuration option that sends the same music signal to all amplifier 
channels using one balanced or single-ended connection. MAT reduces installation 
complexity and cabling requirements in systems containing multiple amplifiers. MAT 
also allows a variety of connection scenarios, including powering loudspeakers that 
have two sets of binding posts and independently powering multiple pairs of stereo 
loudspeakers to extend the listening environment throughout your home.  

A symmetrical input or output circuit that has equal impedance from both input terminals 
to a common ground reference point. The industry standard for professional and sound 
recording installations, balanced connections have 6 dB more gain than single-ended 
connections and allow the use of long interconnect cables. Balanced connections are 
completely immune to induced noise from the system or the environment. 

Single-ended 
A two-wire input or output circuit

. 

Use care when using single-ended connections as the 

ground connection is made last and broken first. Turn the system off prior to making or 
breaking single-ended connections. Single-ended connections are not recommended for 
connections requiring long cable runs.
