Built-in Crossover
Protection Circuitry
All S-SERIES amplifiers feature built-in electronic crossovers.
The 2 Channel amplifiers feature an adjustable low pass crossover.
The 4 Channel amplifiers feature a pair of individually adjustable low pass crossovers.
All S-SERIES amplifiers have been designed with 100% MOSFET power supplies, ensuring
extremely quick switching response and self-protection.
The amplifier protection circuitry will disable the amplifier if input overload ,short circuit or
extremely high temperature conditions are detected. when the protection mode is in
operation, the LED indicator on the front panel will be illuminated, indicating the amplifier has
gone into a self-preservation mode.
If you observe that the protection LED is lit, please check the system carefully to dete rmine
what has caused the protection circuit to engage. The amplifier can be reset by turning the
remote power off and then on again. If the amplifier shut down because of an input overload or
short circuit, be sure to repair these conditions before attempting to power up the amplifier
again.
Your S-SERIES amplifier was designed to operate efficiently at loads down to 2 Ohms.
This means that you can install four 8 Ohm speakers per channel when using parallel
wiring. Increasing the number of woofers per channel at low frequencies (up to 100MHz)
produces an acoustic coupling effect. This acoustic coupling increases your power output by 3 dB
per speaker, or the equivalent of an additional 10W to each speaker.
when operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%.
The current draw will so increase by about the same amount ,also be sure
you have enough current to run the amplifiers into a 2 Ohm load. If you lack adequate current,
your music reproduction will be distorted.
Please note: The gain control of any car audio amplifier should not be mistaken
for a volume control. It is a sophisticated device, designed to match the output
level of your audio source unit to the input level of the amplifier . Do not adjust this input level to
maximum unless your input level requires it. Ignoring these instructions
will result in an input overload to the amplifier, and excessive audio distortion. it can also
cause the protection circuit to engage.
