Definition of Terms
Following are the definitions of key terms used in your owner’s reference manual.
CONNECTIONS
Bridging
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.
Krell Multi Amp Throughput (MAT)
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
and cabling requirements in systems containing multiple amplifiers. MAT also allows a
variety of connection scenarios, including powering multiple pairs of loudspeakers to
extend the listening environment throughout your home.
INPUTS AND OUTPUTS
Balanced
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
r
long interconnect cables.
