Power supply connector
3 - REMOTE TERMINAL: The remote Head Unit output must be connected by a 0,75mm² (18 AWG) cable.
It is recommended that all cables must have tinned ends to improve electrical contact.
1 - FAN: This amplifier has one internal ventilation fan, and cannot be blocked. For perfect functioning, the
amplifier must be installed in a cool and aired place. It is recommended not to embed it, so that the air circulates
throughout the inside of the product extension, thereby preventing the thermal protection from acting.
2 - POSITIVE POWER SUPPLY TERMINAL: Use a 4 AWG (21mm²) cable directly from the positive battery
terminal with fuse (150A), as close as possible from the battery.
4 - NEGATIVE POWER SUPPLY TERMINAL: A 4 AWG (21mm²) cable as short as possible must be used,
connected to the negative battery pole.
NOTE: Only the MD 3000.1 PREMIER amplifier has the voltmeter at the top of the sticker.
RED LED flashes 3x:
When the amplifier reaches the temperature of approximately 80°C (176°F), the thermal
protection starts working, the audio is interrupted and the yellow LED will start flashing. The fans
will be functioning, in order to cool down the components quickly. Only when the amplifier
reaches a safe temperature level, the audio is released and the amplifier gets back to its normal
functioning.
Power supply voltage greater than 16V.
We recommend don’t turn off the amplifier, so that the cooling time will be shorter, through
the ventilation of fans.
RED LED flashes 2x:
Blue LED steady on:
Indicates that the amplifier is turned on.
Flashing yellow LED: Excessive temperature (May be caused by obstruction of the internal fans,
improper installation or poorly ventilated location).
Blinking yellow LED according to music: Indicates that the amplifier is operating at the
threshold of distortion. If the red LED also blinks, it indicates excessive distortion.
Short-circuit or impedance lower than that supported at output.
Red LED steady on:
Supply voltage less than 9V.
