408D DIGITAL CROSSOVER
4
inputs and 8 outputs coupled with an easy user interface,
the TR 408D
Digital Crossover/System Processor has all the audio
processing tools needed for precise crossover and
sound control. Each input allows gain and delay
control,six parametric, low or high shelf filters.
In addition to setting crossover frequencies, each
output may be assigned to any one or a combination
of inputs, allowing programing of four parametric,
low or high shelf filters, delay for time delay
adjustments, output gain, reverse polarity and a
compressor/limiter for speaker protection.
