What is the bridged amplifier about? In a conventional amplifier, one speaker is driven by the positive and negative part of one single output stage per channel, but a bridged amplifier does things differently, using two separate amplifier stages per channel to drive one speaker. To greatly simplify things: one amp pushes the speaker cones and domes, while the other pulls them back.

This allows for greater control over the way the speaker drive units behave, in that the amplifier can make them start moving, and stop, much more precisely.

In the PM-10, the bridged amplifiers in the power output stage - a total of four amplifier channels - allow this control to be combined with huge power output: it delivers 2x200W into an 8ohm load, and can easily cope with demanding speakers or those whose impedance varies widely with frequency, thanks to a 2x400W output into 4ohms.
