Definition of Terms
Multi Amp Throughput
An internal connection option that sends the same music signal to all amplifier channels
using one balanced or single-ended connection. MAT reduces installation complexity

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.
Bridging
An internal connection option that links two amplifier channels to operate as one
combined amplifier channel, greatly increasing the channel's power output.
