- About the Speakers
The Digidesign RM1 and RM2 are both two-way
(bi-amped) active reference monitors with inno-
vations in amplifier and crossover design and
include PMC’s ATL™ (Advanced Transmission
Line) technology.
ATL Technology by PMC
PMC has taken loudspeaker design to the high-
est level with the use of ATL (Advanced Trans-
mission Line). These designs utilize sophisti-
cated cabinets, proprietary drive units and
special absorption materials. -
