The Loudspeaker Frequency Allocator Light is a modified version of the Frequency Allocator. It allows for low latency processing by eliminating the Phase Arbitrator section- responsible for about 150 msec of latency hard coded in its algorithm. Frequency Allocator Light is the answer to requests for a high quality DSP crossover for use with video playback systems such as HTPC. It also allows for multiple instances running simultaniously- perfect for full processing of active surround sound setups. This at an unbelievably low price of $59.00!
