The RCA connections are corrosion resistant for optimum performance and low signal
loss. The RCA connectors are labeled CH1, CH2, CH3, CH4, CH5, CH6.
In applications where RCA signals are not present, the speaker level output from the
head unit can be used. (High-level speaker output to RCA input adapters included).
• Input Gain Controls: Allow you to match the source unit's output voltage to
achieve maximum output from the amplifier. The amplifier can accommodate input
levels from virtually any head unit with an input range of 200mV to 6.0V.
Regarding high-level input: Please use included high-level to RCA adapters.
• Bass Boost: The added boost produces rich, low bass frequencies that are usually
difficult to reproduce in the vehicle/marine audio environment. Bass boost
frequency (50Hz, 0~12dB). (CH5 & CH6 only)
• Input Select [2CH/4CH/6CH]:
2CH: Use CH1/2 inputs and has output to all 6 channels
4CH: Use CH1/2 and CH3/4 inputs and has output to CH1/2 and CH3/4
NOTE: When using 4CH input, CH5/6 output will be NON-FADING.
6CH: This input mode sends each RCA input to the corresponding output.
NOTE: BASS BOOST is always on channels 5/6.
• FREQ All Channels: The crossover frequencies are adjustable from 50Hz to
500Hz. Use this feature along with your speaker manufacturer's recommended
crossover frequencies to quickly design advanced systems.
NOTE: If either of the Crossover Mode Switches is set to OFF, varying the
frequency control will have no effect.
• Crossover Mode (LOW HIGH FULL): A filter is activated by sliding the filter switch
to either HIGH = High Pass or LOW = Low Pass. Each filter is fully adjustable from
50-500Hz. Use this feature along with your speaker manufacture's recommended
crossover frequencies to design a more advanced system.
• Auto Sense (ON/OFF)
OFF: (common application) When source unit remote turn-on wire available.
ON: (factory radio application) Must use included RCA input adapters.
NOTE: In this setting; do not connect anything to REM terminal.
