BUILT-IN TWEETER PROTECTION CIRCUITRY:

The VR Crossover networks are equipped with an advanced electronic tweeter protection circuit designed to minimize the possibility of tweeter failure. This electronic device monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Should this occur while listening to the audio system, simply reduce the volume for a few seconds and the protection circuit will reset itself automatically.

ADJUSTABLE TWEETER LEVEL:

VR Crossover networks also provide two levels of tweeter adjustability designed to compensate for different mounting locations, vehicle interiors and personal taste. The two levels are selectable via a switch located on the top surface of each crossover case. We recommend that you begin listening at the “Reference” position. If the sound seems too bright or aggressive, switch both crossover’s switches to the “-3 dB” position. For quick A/B comparison, it is safe to operate the switches while the system is playing.

SPEAKER PLACEMENT CONSIDERATIONS:

A component system gives you the ability to place the woofer and tweeter separately in your vehicle interior.This can be good or bad, depending on how it’s done.

As a general rule, the tweeters should be placed relatively close to the woofers for best tonal balance and most coherent imaging (the closer, the better). Any separation greater than 8 inches (20 cm) is likely to result in degraded sound quality.

Avoid placing tweeters where they will be blocked by objects in the interior of the car (including seated occupants). When selecting a mounting location, look at both sides of the car to make sure that this location is clear on both sides.

You can always experiment with tweeter placement before committing to a final mounting location. Simply connect the rest of the system and allow plenty of wire length for the tweeters. Using velcro or similar material, attach the tweeters in different locations until you find the one where they perform best.

Woofers will usually be placed into factory speaker locations. If you have some woofer mounting flexibility, keep the followiing in mind: Lower mounting locations, such as the lower front corner of a door or a kick-panel provide the greatest path length distances for the sound emitted by the woofer. For this reason, they are generally more desirable than higher mounting locations. Higher mounting locations will usually result in extreme near-side soundstage bias which compromises the stereo listening experience.

GETTING STARTED:

• Turn off the audio system. It is also advisable to disconnect the negative (-) terminal of your vehicle’s battery whenever performing installation work.

• Before cutting, drilling or inserting any screw, check clearances on both sides of the planned mounting surface. Also check for any potential obstacles, such as window tracks and motors, wiring harnesses, etc. Check both sides of the car, many cars are not symmetrical!

• Always wear protective eyewear.

It is absolutely vital that your component system is connected as shown in the diagram below. Failure to connect the system as shown will result in damage to your speakers which is NOT covered under warranty. Do not substitute different crossover networks into your VR525-CSi System. Only use crossover networks clearly marked “VR525-CSxo”.
