12 OUTPUT LIMITERS
High performance digital limiters are provided for each output with control
over attack time, release time and threshold level parameters (see page
15). This level of control allows the user to balance the required subjective
quality of the limiter against the driver protection requirements. It does also
mean that an incorrectly set limiter may sound awful! In particular, as with
all limiters, using too fast an attack or release time will result in excessive
low frequency distortion. In the ‘design a crossover’ sub-menu there is an
option for automatic limiter time constants. In this mode the time constants
will be automatically set from the Highpass filter frequency. See table
below.
Table of automatic attack and release times.
The time constants are set by the high pass filter frequency for that
channel. It is highly recommended that the automatic setting is used to
ensure highest sound quality and simplicity of configuration.
