Classical & Linear Phase Crossover

Classical Crossovers

Bessel, Butterworth and Linkwitz-Riley crossovers are provided, selectable up to 48 dB per octave. The crossover interface also allows you to quickly add low shelf, high shelf, and parametric filters to each output. These filters use the latest in digital signal processing technology, maintaining their symmetrical shape at high frequencies.

You can also build your own custom crossover functions by enabling or disabling high pass and low pass filters on any output channel.

Linear Phase Crossovers

Linear phase crossovers are another feature separating the Dolby Lake Processor™ from ordinary processors. Linear phase crossovers can match traditional crossover slopes, such as 24 dB per octave and 48 dB per octave, but they are also capable of transition slopes exceeding 180 dB per octave.

These slopes offer dramatic benefits when applied to various types of loudspeaker arrays. Off-axis lobing and cancellation between loudspeakers are dramatically reduced. Greater control over slopes means that different speaker cabinet types can be more easily mixed and matched. Also, a loudspeaker’s impulse response is significantly improved, providing a time-coherent wavefront.

Additionally, improvements of up to 3 dB or more in acoustic output power may be expected in some frequency ranges.
