Dual TBX10A 10 端口式封闭式柜体与内置音频放大器说明书

TBX10A INSTALLATION/OWNER'S MANUAL 10" Sealed Enclosure with Built-in AmplifierPREPARATIONGetting StartedThank you for purchasing the Dual TBX10A 10" ported enclosure with built-in amplifier. Although Dual has attempted to ensure the information in this manual is accurate, please be aware that any part of it is subject to change without notice. Please read entire manual before installation. Due to the technical nature of amplifiers, it is highly recommended that your Dual TBX10A is installed by a professional installer or an authorized dealer.Before You Start• Always disconnect the negative battery terminal. Consult a qualified technician for instructions if you are unsure.• Avoid installing the amplifier where it would be subject to high temperatures, such as from direct sunlight, or where it would be subject to dust, dirt or excessive vibration.• Use extreme caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring.• All amplifier installations require power, signal and speaker wires (not included).• An amplifier installation kit (sold separately) is highly recommended to facilitate the installation. Consult your dealer for recommendations. Mounting Location• Choose a mounting location for the TBX10A. Suggested locations include behind a seat or in the trunk.• For optimum performance, make sure to provide at least 1" of space around all sides of the amplifier.• Do not mount the TBX10A under carpets or where airflow is restricted.• Do not install the TBX10A where it may be exposed to moisture.• The optimum mounting location varies between vehicles. Remember to test all amplifier functions before completing the final mounting procedure.The following installation instructions are intended to be used as a basicguideline. If you feel unsure about installing this speaker system yourself, Dual recommends acquiring the services of a professional car audio installation center.Before installation, please review the following guidelines:1. Be sure to carefully read and understand the instructions before attempting to install this product.2. If additional wiring is required, we recommend running all wires prior to mounting your enclosure in place.3. To ensure reliable performance and minimize signal or power loss, use the highest quality connectors available.4. Never run speaker wires underneath your vehicle. Running speaker wires inside the vehicle provides the best protection from exhaust, heat and environmental elements.5. Avoid running wires over, near or through sharp-edged surfaces. We suggest you also use rubber grommets to protect any wires routed through metal, especially the firewall.6. When running the speaker cable to the amplifier, avoid running it near sources of high current (i.e. wiring harnesses, battery cables).Safety FirstThe following instructions are designed to ensure safety during installation and use of the TBX10A. Failure to heed these instructions can result in injury or damage to the unit or vehicle.CAUTION!Connection DescriptionsNote: Be sure to follow specific instructions included with your amplifier installation kit (not included with this amplifier). The information below should be used a general guideline only.Power Wire (+12V)• D isconnect negative battery terminal before proceeding. Consult a qualified technician for instructions if you are unsure.• P lan wire routing before cutting any wires to length. Begin by routing the power +12V wire from the battery to the amplifier location. Use a grommet when running wires through the firewall or metal openings. Avoid running the power wire near existing vehicle wiring to prevent induced noise from entering the audio system.• U se extreme caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring.• T he +12V wire MUST be fused within 18" of the battery for protection of the vehicle’s electrical system.Ground Wire (GND)• T he amplifier ground wire should be as short as possible. Choose a clean unpainted section of metal or the vehicle chassis when attaching the ground connection. Be sure to clean the area of any dirt or grease.Remote Turn-on Wire (REM)• T he remote turn-on wire connects to the head unit's amplifier turn-on lead or other switched 12 volt source.Input Signal • T he amplifier's input signal connects to the receiver's low level (RCA) or high level (speaker wire) outputs.CAUTION• N ever run any wires underneath or outside the vehicle.Phase Control Power Indicator Protect Indicator Input Level ControlCrossover Frequency Bass EQ Fuse (15A)Power / Input ConnectorConnections and ControlsHIGH LEVEL 12345678Main Power ConnectionsConnect BAT+, GND and REM wires accordingly. A suitable fuse MUST be installed on theBAT+ lead within 18" of the battery for protection of the vehicle’s electrical system.Power/Ground Wire SizeFor optimum performance, use only 12 gauge wire or larger. Make sure to use the same size power and ground wire.Typical Wire RoutingHigh Level Input (Speaker Wire)High level inputs should only be used when RCA outputs are not available from the head unit. Connect the head unit speaker outputs to the high level input connector as shown below. The black wire (signalreference ground) may or may not require a connection to chassis ground - depending on your particularinstallation. Do not use both low and high level inputs at the same time. Connect only one or the other. MountingPlace the TBX10A on the strapsScrew the mounting brackets securely to the floorboard of your car or tuck as illustratedLace the straps so that they pass through the brackets as illustrated.Lace the straps through thebrackets as illustrated.Fasten the buckles as tightlyas possible.Low level (RCA) input signal is preferred for best performance. Typical trunk-mount installations require a 17-20 foot RCA cable. Most trucks and behind-seat applications require a 6-12 foot RCA cable. Using twisted pair construction RCA cables will minimize noise.The adjustable crossover is used to filter outfrequencies above 50Hz ~ 250Hz. Adjust it to wherethe TBX10A sound output blends with the rest of the sound system.The phase control compensates for delay between the TBX10A output and the rest of the sound system. Begin with the phase control set to 0 degrees. If the sound is adequate from the normal listening position inside the vehicle, no further adjustment is necessary. If the sound is thin or lacking bass, adjust the phase control until the bass is full and punchy.The input level control (LEVEL) is used to obtain the best possible match between the head unit audio output and the amplifier input. Begin by turning the input level control fully counterclockwise. Next, turn up the head unit volume control around 3/4 of the way up. Adjust the input level control clockwise until audible distortion is heard, then slightly counterclockwise to provide the best match.The LED indicator illuminates green during normal operation.Input Signal ConnectionsLow Level (RCA)Crossover Frequency Control Phase ControlInput Level ControlLED IndicatorControl Setup and AdjustmentThis warranty gives you specific legal rights.
