Manual-8 rear panel: alternate mono 4-way connections the switching in the ac 23s will result in a mono 4‑way configuration with the crossover ranges sub, low, mid & high from left to right across the bottom front panel. By connecting a patch cable from the channel 1 high out to the channel 2 input,...
Manual-9 operating instructions selecting crossover frequencies most speaker manufacturers supply low and/or high frequency cut-off points for each driver, especially if these are supplied in a system. These cut-off frequencies are based on each driver’s per- formance at and beyond this point, with ...
Manual-10 time delay adjustment using realtime analyzer & pink noise this method outlines the use of a realtime analyzer, pink noise generator and flat response microphone to set crossover time delay. The procedure applies to virtually any analyzer system. We recommend using a 1/3 or 2/3-octave anal...
Manual-11 time delay adjustment using spl meter & tone generator if an analyzer is simply not available, an accurate delay setting can be obtained by using an spl meter (obtainable at most local electronics stores) and some kind of variable tone generator. In order to exclude the effect of room acou...

Manual-13 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 plac...
Manual-14 setting levels using an spl meter & pink noise generator the mute switches on the ac 23s make using an spl meter an easy and relatively accurate means of tuning a system, avail- able from a local electronics store. You may also use a sweep or tone generator in place of a pink noise source....
Manual-15 constant directivity horn eq mod constant directivity (cd) horns need additional equalization to help cover the same area a long throw horn can cover. Additional circuitry has been added to the ac 23s for additional equal- ization of the high frequency outputs for the cd horns. This modifi...
