The compression ra o can be adjusted from 2:1 to
32:1
.
The so and hard inflec on point can be adjusted,
among which 0% is the hard inflec on point and
100% is the so inflec on point
.
Compression compensa on can be set range:
0~12dB
.
5.3.7
Peak limit
It is mainly used to limit the peak signal and protect
the woofer from mechanical damage caused by the
voice coil movement exceeding the linear stroke. If
you need to accurately set the stroke/frequency and
voltage curve of the unit, you can consult the
manufacturer of the unit Or measure and obtain data
by yourself
.
For example, using the ** model woofer, it is found
that the stroke of the unit reaches the limit of 12mm
at 103 volts. At this me, the amplifier magnifica on
is 38dB, 103/80=1.2875v, 20log (1.2875/0.775)=4.4,
that is, the peak compressor's The startup threshold
is 4.4dBu
.
Peak limiter switch
.
The threshold can be adjusted from -10dBu to
+20dBu
.
The adjustable range of the release me is: 100ms to
15000ms
.
The a ack me can be adjusted from 0.1ms to
1000ms
.
5.3.8
Hard Limit
There is no se ng of start me and release me in
the hard limit. By directly se ng the limit threshold,
the internal signal flow is prevented from being
distorted
.
It can be used to match the gain structure of the front
and rear systems. The simple ones are o en the most
intui ve and effec ve
.
5.3.9
X-over mode
The MIR-A series has built-in three kinds of crossover
filters
.
①
Tradi onal IIR filter, including three types of
Linkwiz-Raylei/Bessel/Bu erworth, with a
maximum slope of 48dB/oct
.
②
MIR linear phase IIR filter, using Marani's
exclusive algorithm, retains the shape of the
Linkwitz-Riley /Bessel/Bu erworth filter types
without phase distor on, maintaining the linear
phase, and controlling the me delay at the
same me In a reasonable range, it can directly
replace the tradi onal IIR filter for speaker
frequency division, and only need to align the
delay
.
③
FIR finite impulse response filter, allowing users
to customize the window func on in the
so ware to generate high-slope and steep filter
shapes, and also accept FIR convolu on
generated by external third-party so ware
based on measurement, which can realize
complex filter shapes and mul ple sec ons The
parameters are equalized and the phase is
corrected at the same me
