[. . . ] The subwoofer channel also contains o selectable 12 dB or 24 dB (mono) per octave filter to set the "tightness" contour of boss frequencies. The subwoofer channel has seporote On/Off controls on both front/rear outputs for constant or fodwble buss, and on 18 dB peg octave filter to suppress harmful subsonic signals.

The ending cro-r point is automatically set as o symmetrical value determined by the sstting made on the TWEElER FREQ control. SATEUlTE/MlD LEVEL: Continuously-variable output level control for adjusting the stereo level from the Front SATELLITE/MID OUT jacks. Power Indicator Red LED lights when power is on. APPLlCATlONS The SvX4 can be used in either 2. ~9 or 3-way system designs, OS shown in Figures 3 and 4. Figure 3. An example ofo system using on 5VX4 conhgured for 2. way operotron. The Front TWEETER OUT drives CI front amplifier and a tzair of hveeten. The Front HIGH PASS OUT drives CI second front amplifier and a set of mid-boss componenk. The Rear HIGH PASS OUT drives a (third) rear amplifier and o pair of satellite speakers containing passive cm~sovers feedin tweeters and mid-buss componenh. The SUB OUT channel drives c1 IL rth amplifier ond subwcofer Fkers. INSTALLATION Automotive sound system installations can ix tricky, especial1 for firsttimers. For this reason, we recommend using o professionar. installer, who has the tools and, more importandy, the experience to do the job right. If you decide to install the equipment yourself, we hope this monua will serve 01 (I helpful guide. Befwe attempting on i&&ion, tidy the applications shown in Figures 3 and 4. Use either proven deri n as a "blueprint" for your system inst&tion, or as 0 starting point ir creating your own custom system. With proper instolbtion and odjushnent, the SVX4 will reward you with reliable operation and optimum performance. Figure 3 shows (I basic system that uses sat&e speakws for hont and rear sound staging. The SVX~ is configured fur ~-way operation by sliding the 2~13~ switch to 2~. Audio signals from Front and Rear HIGH PASS OUT drive front ond rear amplifiers. Passive crossovers on each amplifier's wtpuh further divide the amplified signals to the satellites' mid-range and tie&r speakers. Figure 4 shows a design that user separate tweeter and mid-buss syv terns for Ihe frcnt channel and soklfik lpeokers for the rear channd. The SVX4 is configured for 3. ~0~ operation by sliding the 2W/3W switch to 3w. d oted RCA type jocks for all audio connections, level inputs (see Connections and Controls). For best signal transfer, we recommend using Soundstream DL*l Audio Cable, Streamline Audio Cable, or on equivalent premium cable.
