JBL 5 Channel Marine Amplifier - JBLMA5055AM

Features

Compact size

The JBL marine A5055 amplifier features a low-profile chassis and a small overall footprint to fit in more vehicles where available space is limited.

High and low level input

Speaker-level and low-level inputs allow the marine A5055 to integrate with both aftermarket and factory marine stereo systems.

Variable crossover and bass boost

Unlike many amplifiers available at similar prices, the JBL marine A5055 features variable electronic crossovers and bass boost circuits allowing for precise system tuning and performance.

Low noise and distortion

The marine A5055 has been engineered using Balanced Differential Inputs to ensure low noise and distortion even at high output levels. This also makes it far less susceptible to line induced radiated engine noise.

Input Level Control

When low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 4Vrms. When high-level inputs are used, this control adjusts the input sensitivity between 1Vrms and 22Vrms.

Full on-board protection

On-board circuitry protects the marine A5055 from shorts, high-temperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists.

Phase Switch

This switch changes the input phase to inverted or non-inverted. This is especially helpful with the subwoofer channel.

RBC wired remote

The RBC wired remote is an easy installation and can be mounted for convenient volume adjustment from driver's seat.

Class AB+D amp technology

The JBL marine A5055 5channels subwoofer amplifier delivers 760-Watts RMS using a Class AB+D amplifier design to ensure high output and minimum current draw.

Turn-on mode

This switch changes DC to REM to adapt with low-level signals or high-level signals, this is especially helpful as part of remote turn-on lead of your installation more choice .A selectable "Turn-on mode" can protect battery to avoid current drain, when you don't expect turn on your amplifier.
