LIR crossover filtering
This device includes Linear Impulse Response (LIR)
crossover filtering, which results in a linear phase
crossover that has a constant delay regardless of
frequency. This is unlike other types of crossover that
delay different frequencies to different extents, thus
smearing the arrival times. The LIR crossover can thus
be described as having a flat group delay response and
is thus entirely free of group delay distortion. The shape
of the LIR crossover filter is quite similar to a 4th order
or 24dB/Oct Linkwitz-Riley filter and maintains zero
phase difference between the adjacent bands across the
crossover region to keep the polar response rock steady.
FIR linear phase equalisation
The input high shelf equalisers use finite impulse
response (FIR) filtering to produce linear phase
equalisation; that is, all frequencies are delayed by
the same amount, perfectly preserving the transient
response. This can also be important in applications
where different amounts of EQ are applied to different
parts of a speaker cluster, such as to add 'Throw' EQ
boost so that parts of cluster that are throwing further
can have HF absorption correction added. If this EQ is not
linear phase, then the zones where the speakers combine
may suffer frequency response anomalies. Linear phase
equilisation solves this problem.
