Roswell R1 550.2 2-channel amplifier – marine Class-D audio

This marine amplifier delivers efficient power and clear sound for your onboard audio system. The 2-channel Class-D R1 550.2 delivers 165 W RMS per channel into 4 Ω and 275 W RMS per channel into 2 Ω. Featuring a calibrated crossover, differential RCA inputs, and conformal-coated circuit boards, it's designed for reliable performance and clean installation, even in marine environments.

Key Features

• 2-channel Class-D design, bridgeable for flexible configurations
• Output power: 2x165 W RMS @ 4 Ω and 2x275 W RMS @ 2 Ω
• Calibrated crossover (FULL/HPF/LPF) on channels 1-2
• Differential RCA inputs help minimize interference
• Printed circuit boards with conformal coating for extra protection
• Nickel-plated, marine-grade wire terminals
• Space-saving, stackable design
• Illuminated logo acts as a power indicator

Efficient power for your tower speaker setup

The R1 550.2 is compatible with an R1 Tower Speaker setup and combines high efficiency with control. The Class-D platform keeps power consumption low, while the calibrated crossover (Full/HPF/LPF) helps you tailor the sound to your speakers. Differential RCA inputs minimize induced noise, and nickel-plated terminals ensure strong, durable connections onboard.

Thanks to its stackable enclosure, the amplifier also fits into more compact installations. The conformal-coated circuit boards and marine-grade finish contribute to reliable operation in a nautical environment. The illuminated logo provides instant visual confirmation that the amplifier is receiving power.
