13. DIGITAL PROCESSOR FILTERING
13.1. Single-Amplifi er Drive (Factory-Setting)
Although the speaker can be operated without a digital processor, it is recommended that the speaker be used
in conjunction with a digital processor for better sound reproduction. Recommended setting parameters are as
follows.
13.2. Bi-Amplifi er Drive
Digital processing is required after the drive system has been changed to bi-amplifi er operation. By inputting
an optimum signal to the woofer and tweeter using the digital processor, a high sound quality output can be
realized. Recommended setting parameters are as follows.
