    NOTE An EXT.AMP.CONT. terminal can only be attached if Kenwood centre unit is a model released in 1999 or latter, and has an “EXT.AMP.CONT.” cable. Using the external amp control, up to 3 power amplifiers can be operated simultaneously (although this may not be possible, depending on the type of wiring cable used, and its length).

    Connection Power cable connection 2WARNING To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal. Wiring • If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery cable.
  • Page 11 Sigma servo feed back The sound reproduced through conventional amplifiers is distorted due to the counterelectromotive force produced in the oscillating system of the speaker. The counterelectromotive force is particularly high with the woofer which requires a large drive mass.The sigma servo connection reduces distortion caused by the counterelectromotive force by including the circuit up to the speaker terminals in the negative feedback loop.

  • Page 12: Adjustment Method

    Connection The acoustic properties of vehicle compartment tend to 0 dB 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.
