Main Features of the DSR Series
■
Speaker processing functionality
provided by internal DSP
(DSR112/DSR115/DSR215)
The internal DSP delivers high-resolution sound by using
speaker processing functionality that has been optimized for
each model of the DSR series.
■
FIR-X tuning
™
feature
(DSR112/DSR115/DSR215)
Linear phase FIR filter provides natural sound quality and
smooth frequency response without phase cancellation
around the crossover point.
■
D-CONTOUR (Dynamic CONTOUR)
feature (DSR112/DSR115/DSR215)
D-CONTOUR is a newly developed three-band multiband
compressor. It dynamically adjusts the level of each fre-
quency range according to the volume of speaker outputs. It
boosts the high and low frequencies when the volume level is
low, and it reduces the amount of boost when the volume
level is high. So that it delivers powerful sound tailored to hu-
man hearing. For example, this is useful for dance music,
etc., if you want to emphasize the rhythm.
■
Light and compact
Featuring class-D amplifier, switching power supply with
PFC, and light powerful magnetic neodymium magnet
(DSR112 and DSR115 only) provides top-level light and com-
pact body in the class.
■
Powerful protection function
Separate advanced protection circuits in the speaker unit,
amplifier unit, and power supply unit ensure optimum reliabil-
ity and long equipment life.
