About the FUSION FM-402

Sweet sound from a tough marine amp

Designed by boaters for boaters, FUSION's FM Series marine amplifiers will add new life to your favorite songs without fallign prey to the extreme heat and moisture of the marine environment. The well-engineered heat sink keeps temperatures under control, even during hard use, while a special cooling system keeps damaging heat away from the semiconductors. FUSION's Regulated Amp Technology ensures that you get the power you want without using up the voltage you need for other things.

Plenty of power for your subs

This 2-channel amplifier will deliver 50 watts RMS each to a pair of speakers, or send 160 watts to a sub or two. Whatever the job, you can adjust the high- and low-pass filters to maximize your system's performance. These FUSION amps use heat-tempered, conformal coated circuit boards for durability and gold-plated connectors for consistent signal flow, giving you all the clean power you need to make a day on the water sound like a night on the town.

Controls

Level (Gain): The input gain (rotary control) is adjustable from 300 mV to 8 V to match the output voltage of the source unit.

Subsonic: The subsonic filter (rotary control) frequency is continuously variable from 20 Hz to 55 Hz and the slope is 18 dB/octave. The purpose of a subsonic filter is to remove extremely low frequencies that can't be accurately reproduced by the speakers, and may cause distortion.

Bass Boost: A rotary control allows increasing the bass output; it's continuously variable from zero to +18dB and centered at 45 Hz.

High Pass Frequency: When the high pass crossover is engaged, the frequency is continuously variable from 40 Hz to 300 Hz. The crossover slope is 12 dB/octave.

Low Pass Frequency: When the low pass crossover is engaged, the frequency is continuously variable from 40 Hz to 160 Hz. The crossover slope is 12 dB/octave.

X-Over Selector: A three position switch specifies the crossover mode; select Low Pass, High Pass or Off (full range).

Connections

Power/Ground/Turn-On: The amplifier features set-screw terminals for the power, ground, and remote turn-on connections:

  • Power and Ground: set-screw; accept up to 4-gauge wire (4-gauge power and ground wires are recommended); a 4mm Allen wrench (not included) is necessary to make the connections
  • Remote Turn-On: set-screw; accepts up to 10-gauge wire; a 2.5mm Allen wrench (not included) is necessary to make the connections

Speaker Output: The speaker output terminal strip will accommodate spade connectors or ring terminals up to 0.335" wide.

Preamp Inputs: The FM-402 features one pair of RCA input jacks.

Preamp Outputs: One pair of RCA pass-through preamp outputs make it easy to connect a second amplifier without running another cable to the source unit. The outputs are not affected by the FM-402's gain, bass boost, or crossover settings.
