    Manual- time delay adjustment before jumping feet first into the realm of time delay and how to adjust it, it might help to spend a moment here to re-af- firm why on earth this delay is really necessary. For a detailed and enjoyable short course on time delay, linkwitz-riley and other mouth-watering...

    Manual- step by step procedure a 3-way mode consisting of high, mid and low drivers is used here as an example. For 2-way systems, use the same procedure by replacing low for mid and following steps 2 through 5. Note: if you are running two separate channels on the crossover, tune up only one channe...

    Manual- setting the output level controls choosing the crossover frequencies was the easy part. Now it gets real fun. The idea is to set the output level controls on the crossover so that the entire speaker system has a uniform, flat response. Unfortunately, the room in which the speakers are placed...
