This tR" we-channel electronic crossover is equipped with separate front ond rear stereo inpuk and includes controls for configuring two~woy or three-way crossover systerns. With this design, the fader control (on the head unit) always remains o&e, allowing you to achieve o desired front/rear sound bolonce. configumtion, the SVXA provides high ~ss ond subwoofer ~(1 ;$$$3, x,mode, incoming stereo audio is divided into band,m, ou us r nt tweeter and mid-range speakers, o high pass output for rear speakers, and low frequency outputs for subwoafers. The individual level controk and continuouslywriable, 12 dB per octow filters ive you a wide range of adjustment options. High input levels (e.g., !om o factory radio] ore easi accommodated via plug-in terminal strip and ossocioted level matek control. 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. We USB only premium parts to buikl ah SVX4, in&din cbubk-sided circuit beads, h'lm capacitors, sea 7.lmmenlble ed masked gloss e pobdomekn, ~pkatd RCA input/~con~neaon, and orvgged painted steel enclosure.

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. The SUB OUT channel drives on amplifier and subwoofer 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.

You con route the new wires under the carpeting, but make sure hey do not interfere with the vehicle's normo opemtion. Keep all wires inside the vehicle, hidden from pclssengerr.

Oihewise, follow these steps to adjust the sw4 crossover controls: 5. Adjust the hveetw and mid frequency controls (or satellite frequency coned in ZW] while listening to music. T s&in9 the contm to either side of the initial 12 o'dock position on 7note ony differences in the vccal~. With some eqerimetition, you'll find the setting that sounds best. 6. Adjust the subwoofer frequency in the same way described in step 5. This time listen to the bars. You should find o setting that will give you o solid sound with minimum "boom" from resonating frequencies. Experiment with the 12 dB/24 dB button. The 24 dB slope will produce o "tight" mono bass, while the 12 dB slope will create o %osen stereo bass. location and Mounting The SVX~ is compact in size and it genemtes virtually no heat. It con be ssenger cornpatient, trunk, or located almost anywhere within the storage area. However, do not instol p" SVX4 in the engine comportthe ment, or in any outside location exposed to dirt and moisture. Use the SVX4 os a tern late to mark dn'll holes.

For New installations If you ore instolling the SVX~ os part of new system, we suggest "bench testing" your entire system prior b mounting ony components. By connecting the system to on external +I 2 V dc power source, you con ted the components outside the vehicle to verify your instollotion scheme. Otherwise connecting the system components to your vehicle's elec' ?&cm octualty mounting each component. hical system In either case, connect the componenk e.xoc$ os intended in the final inatcllotion. Make ail power connections lost, test the system, and then disconnect all power until final installation is complete. Connecting Cabler and Power Wires 1. Make sure power to your audio system is off. 2. Connect audio signal cables according to your systerr plan. NOTE: For high level inputs, insert the bare-end wires from the factory radio harness into he openings located on the enclosed mole barrier strip connector. Follow the wire codes screened on the SVX4's rear ponel, os shown in Figure I. After tightening the screws at each opening, insert the connector into the matching female connector on the SVX4. 3. Connect the block tire to good chassis ground (e.g., bare metal or bolt, not pointed or coated). 4. Connect the orange wire to your head unit's renwte turn-on connection. This enables the SVX~ b &low o timed sequence for minimal turnon and turn-off thumps. 5. If desired, connect the orange/black wire (from the High Current Remote Output de circuit) to the power amplifie& remote input connection (for omp #her turn-on d&y). ?. 6. Connect the red wire directly, through o 0.5 A in-line (fast-blow) (use, to o constant +I 2 Vdc scarce, so that it is "hot," even when the ignition is off. Try connecting it to he battery cable itself, or kapping into a power lead on an amplifier. Audio Signal 6 7 SERVICE Your SVX4 is protected by o limited warron~.
