PLD: A new paradigm
The innovative technology built into the PLD amplifiers represents a very new paradigm of audio amplification, one with-
out many of the restrictions and burdens that we’ve had to bear in the past.
Channel density, power density
Among professional power amps, the most common size is 2RU, and the vast majority also have two audio channels. That
means that if you happen to need, say, eight channels of amplification, you’ll need at least 8 rack spaces in your equip-
ment racks—maybe even more, if they are very high-power 3 RU or 4 RU models.
But imagine, with PLD you could now have those same eight channels of ampli-
fication—with up to 2000 watts each—in only four rack spaces, with a total weight
of only 44 pounds.
