DPR-901ii
1.0 Introduction
Introduction
Congratulations!. Whether you’re a sound engineer, producer, consult-
ant, installer or musician, you’ve just added a powerful new weapon to
your audio armoury.
The DPR-901ii is a new class of audio equaliser. Both subtle and power-
ful, it builds on the established problem solving capabilities of paramet-
ric equalisers.
It’s uses range from processing and sweetening speech, instruments and
composite music, through SPL control, to loudspeaker system and room
tuning. The DPR-901ii refines the EQ process, makes it more specific -
and expands it too.
For the first time, changes in EQ and signal dynamics at the EQ’d fre-
quency can be created which are triggered either above or below the
individual threshold levels in four adjustable frequency bands. The
changes in tonality can range from the subtle and highly specific, up
to the extremes of instrument effects. Either way, the DPR-901ii’s unique
subtractive process coupled with state-variable equalisation ensures
uncoloured, low distortion sound. Group delay in particular is low and
uniform, maintaining vital accuracy in the time/transient domain that is
lacking in the majority of conventional equalisers with ‘Bell’ response
envelopes.
