USER MANUAL KAC-X811D KENWOOD

Safety precautions A WARNING To prevent injury or fire, take the following precautions: + When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 8 mm? (AWG 8) or more to prevent wire deterioration and damage to the wire coating. + To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit. Ifthe unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer. + Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched ACAUTION To prevent damage to the macl precautions: + Be sure the unit is connected to a 12V DC power supply with a negative ground connection: Do not open the top or bottom covers of the unit. + Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing When replacing à fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction To prevent à short circuit when replacing a fuse, first disconnect the wiring harness. e, take the following Available Control Units: A KENWOOD LX-Bus supporting Center Unit released in 2004 or later can control this unit. The operations of the (LX) AMP Control are explained in the Operation Manual of the Center Unit. + The LX AMP and the sensor unit cannot be connected simultaneously. You must connect any of them at a time. NOTE + Ifyou experience problems during installation, consult your Kenwood dealer. + Ifthe unit does not seem to be working right, consult your Kenwood dealer. 2 English 3.KAC-X811D_M_IUS.ind& Cleaning the unit IF the front panel gets dirty, turn off the power and wipe the panel with a dry Silicon cloth or soft cloth. ACAUTION Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off. To prevent battery rise When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. Use it after starting the engine Protection function There is a Protection function installed in the unit to protect the unit and speakers from various problems. When Protection operates, the display informs you ofthe condition Display Informations "ET ihen te inside ofthe units overheating en te uni es failed and direct uen voltage is generated to the speakers output. “er Turn the power OFF and release the protection. the *E-02' code does not disapper, contact our Kenwood dealer. Vihen te speaker cord is short ii When te speaer output in contact with the vehice ground "OL" display is blind ‘When voltage gets out of operation range. Wiring + Take the battery wire for this unit directly from the battery. Fits connected to the vehicles wiring harness, it can cause blown fuses etc. Ifa buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire. Do not allow the wire to directly contact the edge of the iron plate by using Grommets. Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery's negative © terminal. Do not turn the power on if the ground wire is not connected Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit fuse capacity or somewshat larger. For the power cord and ground, use a vehicle type (fireproof) power wring cord with a current capacity greater than the units fuse capacity. (Use a power wiring cord with a diameter of 8 mm? (AWG 8) or greater) When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier. Speaker Selection + The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage. + Use speakers that have an impedance of 1 or greater. When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier.

Band Reject Filter The acoustic properties of vehicle compartment tend to cause oscillation due to resonance or unclearness of sound due to standing waves at certain frequencies The band reject filter can solve the problems of resonance or unclear sound with minimum influence on the sound quality because it eliminates only the frequencies causing resonance or standing waves. 0 dB 1 Frequency Troubleshooting Guide ΠAdjustment method: The band reject filter cuts only the limited frequencies to minimize influence on the sound quality. Therefore, its effect cannot be obtained unless the cutoff frequencies are set accurately to the frequencies causing resonance and standing waves. The band reject filter can be adjusted according to what you feel through your ears, but we recommend the use of a signal generator or a spectrum analyzer with a fine frequency measurement capabilty for the adjustment. + Adjustment using a signal generator: Output a sine wave, vary its frequency to find the frequencies at which the vehicle compartment resonates or volume increases (standing waves occur), and set the BR.F FREQUENCY control to the position with which the resonance and standing waves disappear. + Adjustment using a spectrum analyzer: Output white noise (sound in which all frequencies are at a certain leve), find the peak frequency observed on the spectrum analyzer, and set the BRF. FREQUENCY control to the position with which the peak observed on the spectrum analyzer disappears. What might appear to be a malfunction in your unit may just be the result ofslight misoperation or miswiring. Before calling service, first check the following table for possible problems.
