Lake EQ can run convolution without propagation delay. In
order to achieve this the EQ imposes group delay in phase
linear filtering. In order to reduce or remove this group delay
Lake has introduced the “optimum phase”. Using the optimum
phase, filters can be programmed to have zero or minimum
phase delay, the trade-off however is an increase in phase
distortion. Phase distortion can be reduced dramatically by
selecting a phase delay value slightly larger than zero, for
