TROUBLE SHOOTING
NO SOUND ( NO OUTPUT )
@ Please check all connections, cables' rounting, short & voltage
@ Please check the fuses , If they are blown, please replace with new one.
@ Please check whether speakers work well, you can test speakers by connecting to
another amplifier
PROTECTION
@ Please check overload, overheat ( thermal ), short and voltage, DC offset.
@ Minimum working impedance is 1 ohm for all BC amplifiers as single unit.
and 2 ohm stable for linked operation.
@ If amplifiers are shut down due to heat, they will be on some minutes later after cooling
down.
Please make better airflow and no obstruction around amplifiers for thermal protection
@ BC2000D’s working voltage is 8.5V ~ 16V
BC3500D & BC5500D’s working voltage is 8.5V ~ 18V.
@ When over 4V DC comes into amplifiers, then, they will be DC protected.
Check whether amplifiers work after removing RCA-Input.
If amplifiers work, then check DC by checking RCA-input .
When DC is over 4V at input, try by rep12V source unit
.
DISTORTION & NOISE
@ Readjust input level and check the speaker quality at another amplifier
Replace poor quality speakers with good quality ones
@ Check amplifiers and headunit’s ground contact. all grounds should be common.
@ Check Rca Jack, then repalce with new one or reroute Rca Jack.
@ Engine noise is caused by poor grounding of amplifiers, headunit, other components,
battery or alternator, so please check all grounding connection.
POOR BASS RESPONSE
@ Please check speaker cables and reverse polarity.
