2 ENGISH TODUCTI Congratulations on your purchase of a NXS stateoftheart power amplifier with digital signal processing. At NXS Mobile Audio we strive to provide some of the latest technology tools that make the quest for the perfect tune so much easier. Our goal was to develop technologically advanced amplifiers completely adjustable to the acoustics of each vehicle. ECOMMENDATI A power amplifier s performance is only as good as its installation. Proper installation will maximize the system s overall performance. It is recommended that you have our product installed by an authorized NXS retailer. However, if you decide to install it yourself, please carefully read through this manual and take your time to do a quality installation. Due to continuing product improvements and possible manual revisions, we recommend checking our website for latest product information at IMPOTANT! Before making any connections, disconnect the car s battery until the installation is completed to avoid possible damage to the electrical system. WANG! Exposure to high power sound system can cause hearing loss or damage. istening to your system at loud levels while driving, will impair your ability to hear traffic sounds and emergency vehicles. Use common sense when listening to your system. Serial # Model # 1

3 TAKE CTO The NXS amplifiers feature builtin digital signal processors (DSP). The DSP allows for control and adjustment of sophisticated features previously found only in midto high end dedicated preamplifier equipment. The DSP features are controlled and adjusted with one of the two following components (sold separately). NXI computer interface and NXCS software: The NXI is an control interface which allows the amplifier's DSP to be controlled by a PC. The NXI provides a standard USB plug to connect to a PC and a J11 socket for a cable connection to the Amplifier's DSP Netlink. The NXI is powered by the USB connection eliminating the need for additional power connections. This makes the NXI portable and simple to connect. ENGISH Unlike traditional amplifier installations with the adjustments made on the amplifier in the back of the car, the NXI gives the flexibility to position a aptop PC within the vehicle while sitting in the listening position making the adjustments realtime. This allows for ideal calibration of the system including equalization and time delay. NXCDC InDash Controller: The NXCDC is an optional indash controller for users who do not want to use a PC to setup and control their NXS Amplifiers. Shaped in a convenient D size, the NXCDC features a 4 line CD Display, a function selecting scroll wheel, 4 preset buttons and a 'back' button. This enables the user to select and adjust different amplifiers connected via DSP Netlink in the same car. Basic settings like EQ, Gain, Subwoofer level and Crossover can be selected and adjusted. The 4 presets on the NXCDC can be programmed to recall up to 4 individual configurations saved to the NXCDC. The user can easily toggle configurations biased toward 'classical' vs 'techno' music for instance. There is also a MiniUSB PC computer input connection at the front of the controller. This is to allow PCs with the NXCS software installed the convenience of connecting and controlling the amps through the NXCDC instead of having to run additional cables. NXC emote evel Control: The NXC is a remote level control that gives handsoncontrol over the amplifier(s) output level. The NXC operates through the amplifier s DSP Netlink connection and features an intelligent circuit allowing you to select which amplifier and/or channels you would like to control remotely. Additionally, only one remote is needed to control 2

4 SAFETY PECAUTIS Fuse amplifier s power wire at the battery. ENGISH Be sure to fuse the power wire within 6 of the car's battery. This will protect the car's battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST, the amplifier's builtin fuse will only protect the power amplifier not the car's battery! Use high grade wire connectors. To ensure maximum power transfer and secure safe connections, it is recommended to use high grade barrier spades (for connection at amplifier) and terminal rings (for connection at battery). Do not run any wires underneath vehicle. Exposed wires have a chance of being cut or damaged. It is best to run all wires through the vehicle under the carpet and/or side panels. This lends to a cleaner installation and less risk of damage. Use caution when mounting amplifier. emember there are many electrical wires, gas lines, vacuum lines, brake lines as well as a gas tank in the automobile. Make sure you know where they are when mounting the amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank. un signal wires away from electrical wires. To avoid possibility of induced noise from the car's electrical system (i.e. popping noises or engine noise), run wires away from the car's electrical wiring. Make all ground wires as short as possible and at the same point. In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire as short as possible to reduce the wire's resistance. Also, when using multiple components, make sure all units are grounded at the same point. Avoid sharp edges when running the wires. To avoid the possibility of power, signal or speaker shorts, be careful not to allow the amplifier s wires to come in contact with sharp edges. Use a grommet to protect the wire when running through the fire wall. 3

5 FEATUES AND BENEFITS Digital Signal Processor Builtin Digital Signal Processor that can be electronically controlled by the NXCDC, NXI or NXCS (Sold Separately). The processor features the adjustment of gain, X over, tone, time delay, equalization. DC Offset Protection ENGISH This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current. Short Circuit Protection The circuit protects the amplifier from damage due to a short found in the speakers or wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down. To resume normal operation, correct the problem and turn the head unit off, then back on. The amplifier will reset and play again. Thermal Protection To protect the amplifier circuitry against damage caused by prolonged exposure to high temperatures, a thermal protection circuit is activated if the amplifier reaches excessively high operating temperature. Once the thermal circuit is activated, the amplifier will shut down to cool off. The amplifier will automatically turn back on once it cools down to a safe operating temperature. Power / Protect Indicator The power ED Illuminates blue when the amplifier is on and receiving power. The protect ED Illuminates red when the amplifier has gone into protection mode. Power Bridge Technology () NXS Power Bridge technology gives you the flexibility to combine the power of two amplifiers to double the output power into one speaker load. High evel Input High evel inputs have been included to connect the amplifier to a radio without lowlevel outputs (i.e. factory radio). emote Auto Sensing for High evel Input For added convenience when connecting to factory installed radio s, the high level input has a emote Auto Sensing circuit allowing the amplifier to turn on when it receives signal from the radio. 4

ENGISH Power Fusing This protects the amplifier against short circuits and excessive current. emote Turnon Automatically turns amplifier on when connected to the head unit's remote output. The amplifier will turn on and off with the head unit to save current consumption. This control also operates the reset circuit for the amplifier's protection. It must be connected with the head unit in order to reset protection circuits. Adjustable Input Sensitivity Allows you to finetune the level matching between your source and the power amplifier. 5

Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat. Select the location in which you wish to mount the amplifier. Use caution when mounting amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank in the automobile. Make sure you know where they are when mounting the amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are ready, use a pencil to mark the mounting holes in the bottom panel. After you have marked the locations of the holes move amplifier out of the way and drill small starter holes to make the tapping screws easier to install. Use provided screws to tighten down the amplifier. ENGISH NX

17 Fine tune the amplifier's input sensitivity. FE TUNE THE SYSTEM M The input gain sensitivity control for the NXS amplifier is located on the front panel for all amplifiers except the NX200.2 which is located on the left side panel. This gain control has been included to allow adjustment to properly match the output of the radio. This is one of the most misunderstood adjustments. By rotating the control in the clockwise direction, the amplifier s input will become more sensitive and the music will play louder. This is not a volume control and you will not get more power out of the amplifier in the maximum position! It may seem to deliver more output, but actually the system is only playing louder faster as you turn the volume control on the radio. Ideally, to properly level match the system the goal is to achieve maximum output from the amplifier without distortion at about 3/4 of the volume control. ENGISH To determine if the amplifier s gain is set properly, turn the system on and slowly increase the volume control. You should be able to use about 3/4 volume before the system gets loud but not distorting. It is very important when making these adjustments that you do not over drive the speakers (at point of distortion) this will cause permanent damage to the speakers. If you are unable to achieve 3/4 volume before distortion you will need to adjust gain control (in this case you would reduce the gain). The gain controls should be adjusted very slowly. It may help to have another person to assist you by adjusting the gain controls while you listen for distortion. 16

18 TOUBE SHOOTG THE SYSTEM ENGISH We have put together this troubleshooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise. Before you can properly address the problem, you must first find the component that is causing the problem. This will take patience and a process of elimination. OOK FO...
