Bridged operation
When greater power output is desired, two Nº20.6 amplifiers may be
bridged to drive load impedances of at least 2
Ω
.
Note: Make sure the loudspeaker is rated to handle extremely
high power levels. For example, the output power of a pair of
bridged Nº20.6 amplifiers is four times that of a single unit driving
the same load (see the chart below).

*Continuous sine-wave power. Pulsed power will be higher.
When using Nº20.6 amplifiers in bridged mode with loudspeakers that
are biamp-able, we strongly recommend using a high-quality
electronic crossover and operating in the biamp mode.
For the best bridged performance, we recommend balanced
interconnection. If your preamplifier provides balanced output, follow
the steps below.
