● Newly added DSP plug
-
in
,
providing additional practical plug
-
ins such as high
-
order FIR filter
and feedback suppressor
,
including 96kHz FIR filter
/
dynamic EQ
/
high order signal
generator
/
RTA
(
real
-
time spectrum analyzer
),
etc
.
●
The newly designed Hard Limiter allows constant rate limiting of signals exceeding the threshold
at any threshold value
,
which better protects the driver
.
● Each input and output channel provides a 512
-
tap FIR filter
,
which can be customized by third
-
party software to generate the FIR convolution you need
.
It can be used for speaker presets to
improve the phase response and control the directivity according to requirements
● The newly added MIR linear phase crossover filter has the filter shape of the traditional IIR filter
(
4th
/
8th order Linkwitz
-
Riley
),
but does not produce any phase shift
,
and the resulting delay is
about 50
%
of the FIR filter
.
