Now that you have unpacked the unit and have become a bit familiar with the front panel controls, you can follow the next sections of this manual to begin to set-up and operate your new crossover.Further on in this manual, you will find detailed wiring diagrams of various speaker system set-ups. For detailed diagrams of connector and cable wiring, see page 15 in this manual. ENGLISH MODE SWITCH PHASE MUTE -20 -10 0 +10 LOW LIM The S·3-way can be configured to operate in several modes including Stereo or Mono 2-way, Stereo or Mono 3-way and Mono 4-way. In addition, the S·3-way has a special operating mode; 4-way LOW which is used for ultra-low sub woofer applications. The Mode Switch, located in the center section of the unit, is used to select the operating mode. As you switch through the various operation modes, you will notice that several LED's on the panel are also changing. These are the Mode Indicator LED's and they help you keep track of the changing controls. HIGH INPUT GAIN 0 DELAY 1 GAIN 0 95 MID H MID -6 +6 5 500 0 mSec 2 H MID -12 dB +12 -6 dB +6 LOW HPF FREQUENCY BAND & LIMIT INDICATORS Because the S·3-way can be configured to operate in several different size sound systems, the crossover controls may be adjusted for the frequency division between low, and high, or low and low-mid, or high mid to high depending on the mode. On some crossovers, it is very difficult to get a quick visualization as to what controls are controlling what function. The S·3-Way solves this problem by employing it's Mode Indicator LED's over the Frequency and Gain controls. These provide quick identification of the frequency band that is under control. In the diagrams below, you can see what functions are under control when the associated LED is lit. Also, over each Gain control is an LED that illuminates indicating that frequency band has entered into Limiting. More information on using the Limiter can be found on page 10.
