C7-2K, C7-4K & C7-2000.4 have protection features to prevent any damages from misuse or faulty conditions.

If C7 ampliers sense excessive heat, short circuited speaker, DC or voltage, the protection indicator will

light and the system will be turned o. In order to check the problem, you should turn all levels down and

all power o and carefully check the installation for wiring mistakes or short.

If C7 ampliers shut down due to excessive heat, they will remain in thermal protection until ampliers reach

normal operation temperature. Before removing your ampliers, refer to the list below and follow

the suggested proceedures.

NO OUTPUT

@ Check remote turn-on voltage at amplier and headunit, when remote turn-on voltage is low

or no turn-on voltage, there is no sound.

@Check fuses at the battery side or external fuses and all wire connections

@ Check RCA Input is properly connected.

AMPLIFIER SHUT DOWN ( PROTECTION )

@ Please check POWER, GND and REMOTE wire connection and other wires properly connected.

@ When DC over 4V comes into the amplier, amplier is DC protected. Pls check whether amplier works

after removing RCA-Input. If amplier works, then check DC by checking RCA-Input.

When DC is over 4V at Input, try by replacing head-unit or source.

@ Amplier goes into the thermal protection when amplier is over-heated. Amplier will turn back

on after it cools down. Please install amplier in a better ventilated area.

@ C7-2K & C7-4K have a minimum working impedance of 1ohm as single unit. Strapped connection is 2ohm.

C7-2000.4 has a minimum working impedance of 2ohm stereo or 4ohm bridged.

@ C7-2K, C7-4K and C7-2000.4 voltage protection at low and high is 8.5V to 16V.

@ Make sure Chassis and Remote use same GROUND.

DISTORTION & NOISE

@ Please re-adjust amplier input level which is printed on endplate.

@ Make sure good ground contact of amplier or headunit.

@ Use sucientrly shielded RCA interconnects and good RCA routing.

@ Check all ground connections of all other audio equipment.

POOR BASS RESPONSE

@ Check speaker wiring and reverse polarity.
