JBL MA754AM Amplifier 75w X 4rms @ 4ohms
Model: JBLMA754AM
Features:
- The JBL marine amplifier features a low-profile chassis and a small overall footprint to fit in more vehicles where available space is limited
- Speaker-level and low-level inputs allow the marine to integrate with both aftermarket and factory marine stereo systems
- Unlike many amplifiers available at similar prices, the JBL marine amplifier features variable electronic crossovers and bass boost circuits allowing for precise system tuning and performance.
- The marine amplifier 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.
- 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
- On-board circuitry protects the marine amplifier from shorts, high temperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists.
- This switch changes the input phase to inverted or non-inverted. This is especially helpful as part of system tuning based on the enclosure type and location in the boat.
- Using multiple amplifiers, the marine A754 has full range preamp outputs allowing you to feed an additional amplifier without using splitters.
- The JBL marine A754 4 channels subwoofer amplifier delivers 400-Watts RMS using a Class H amplifier design to ensure high output and minimum current draw.
- 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.
The marine A754 4-channel amplifier delivers a powerful 75-Watts RMS to each of the front and rear speakers in your boat. You can also bridge the amp to 2-channel mode to drive a couple subs with 200 watts RMS or 3-channel mode to drive both a pair of full range speakers and a subwoofer. Speaker-level inputs allow this amplifier to integrate into almost any system, even one using your marine's factory radio. Separate high-pass and low-pass crossovers on the front and rear channels allow you dial in the perfect roll off to best suit speaker placement and cabin acoustics.
