GROUND ISOLATION SELECTOR: This feature allows you to change the power supply ground isolation for different systems. The 2XS helps you avoid these problems by providing selectable signal and power grounds. Audio Control 4XS Manual.
W e need to know that you bought your product from an authorized AudioControl dealer. If somebody takes your 2XS while you're vacationing in Tahiti, insurance companies and law enforcement officials will require some proof of ownership on your part. Turn the volume up while listening for the bass.
LC2i Manual - The LC2i turns on all b y itself.
The Inside PROGRAMMABLE CROSSOVER MODULE: This 14 pin resistor module controls the crossover frequency. We install a 90Hz resistor module at the factory. However, should your system design require something different, they are easy to change. PROGRAMMABLE FREQUENCY MATCH PFM MODULES: This 14 pin module is the same type of module as the one in the crossover module socket. However, the PFM is the bottom limit for the low frequency output. It is set from the factory at 33 Hz. GROUND ISOLATION SELECTOR: This feature allows you to change the power supply ground isolation for different systems. When your 2XS was shipped from the factory, the selector was put in the fully isolated position which we know is the best. Alas, not every other manufacturer or installer devotes so much time and effort into getting their grounds right. Therefore, we have provided other ground isolation options to help if you have a ground loop noise alternator whine in your system. Experiment with different settings if you run into this type of problem. To change the settings, turn system off, carefully move the black jumper from the center two pins fully isolated to either the top two pins 200 Ω or the bottom two pins ground. If neither position eliminates the noise, read on. INPUT GROUND ISOLATION JUMPER: These jumpers provide a hard ground for the balanced input circuitry. Some head units or pre- amplifiers require this for optimum low noise operation. The unit is shipped in the balanced input position. This should be optimum for most applications. Should you feel the need to experiment however, feel free to turn the system off, change the jumper position and see if it helps. These are the inputs which get their signals from the outputs of your head unit or equalizer. The first pair on the left is your high frequency output and the pair on the right is your low frequency output. OUTPUT LEVEL ADJUSTMENTS: These adjustments control the 2XS signal output to your power amplifiers. The circuitry provides output level control to drive any power amplifier with up to 9. This is a really good thing. Please note: the output of the 2XS is proportional to the input it receives. Any less input voltage and the output will decrease. OUTPUT STATUS LEDS POWER: Indicates when the 2XS is turned on, clever! POWER CONNECTOR: A wonderful, removable connector that allows you to hook up all of the power and turn-on wires for your 2XS in the convenience of daylight, and then attach them in the dark recesses of your trunk. You have just purchased the state-of-the-art autosound crossover - the 2XS. This crossover is incredibly adjustable, programmable, and most importantly, the 2XS will make your car audio system sound better. Whether you are a car audio soundoff competitor or just someone who appreciates good sound, the 2XS will provide you with many hours of enjoyment. Please take a moment to familiarize yourself with the many features of the 2XS by reading this manual. Programmable Frequency Match PFM Subsonic Filter Subsonics are low frequency non-musical noises which are present in most recordings and usually occur below the frequencies which human ears can detect. This robs amplifier power, causes intermodulation distortion, and may even cause speaker damage. This PFM filter rolls off these problem-causing frequencies before they get to your amplifiers. Since it is programmable, you can install a PFM resistor module at the ideal low frequency roll-off point like the subwoofer enclosure tuning frequency or the -3dB down point of your system , and get the best possible sound from your system. Line Driver Every electronic component produces a small amount of noise. This noise is the result of electrons bouncing into each other like pinballs. Fortunately, the circuitry in the 2XS has been designed to provide signal gain. This, my friend, is a good thing. Selectable Ground Isolation Ground loops and ground noises are constant threats to a quality car stereo installation. Head unit manufacturers ground their products one way while amplifier manufacturers may ground theirs differently. Unfortunately, these differences can cause ground loops. The 2XS helps you avoid these problems by providing selectable signal and power grounds. Ground loops are now things of the past. The Most Important Instruction of All FILL OUT AND SEND IN YOUR WARRANTY CARD! Also, it is crucial that you keep your invoice or sales slip, since it is your only proof of purchase. If somebody takes your 2XS while you're vacationing in Tahiti, insurance companies and law enforcement officials will require some proof of ownership on your part. For the highest possible product performance and the lowest possible use of aspirin, nothing is better than a profes- sional system installation. Your AudioControl Performance Match audio dealer has the training and equipment necessary to install your 2XS and achieve the best possible sound out of your system. However, if you are a die-hard do- it-yourselfer, this manual will give you all of the information you need to make music with your 2XS. Revised 1998 All rights are reserved.
