Error diagnosis

Help / Solution
-check the fusing
-check the remote wire
-check the +12 Volt connection and wire
-check the ground connection and wire
-check the contact or replace the wire
-check the audio output signal of the head-unit
-check the remote out of the DSP (page 5)
-check the amplifiers power supply
-check the setting (page15)
-check the setting (page15)
-check the setting (page7)
-check the contact or replace the wire
-check the audio output signal of the head-unit
-check the setting of the head-unit
-check the setting (pages 11~14)
-check the setting (page 15)
-check the polarity of the speaker connection
-check the polarity of the high-level input (page 6)
-check the >PHASE< setting (page 15)
-check the >TIME ALIGNMENT< adjustment (page 16)
-reduce the volume level
-check the highpass filter and slope (page 15)
-select the correct input mode
-pay attention to the input sensitivity of the DSP unit (page 18)
-reduce the volume level of the head-unit
-set the sound controls of the head-unit to center position
-deactivate the >Loudness< function of the head-unit
-check the amplifiers input sensitivity
-reduce the level
-reduce the >GAIN< level (page 15)
-select a superior quality head-unit
-use the optical output (if available)
-let the audio store or manufacturer check the head-unit
-the head-unit, the DSP and each amplifier should be wired up to
a common ground and +12 Volt connection
-check the contact or replace the wire
-let the audio store or manufacturer check the head-unit
-let the audio store or manufacturer check the amplifier
-choose another mounting position
-connect the digital MOST audio signal directly to the DSP unit*
