The marine A758 8-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 250 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.
Variable crossover and bass boost
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.
Low noise and distortion
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.
Input Level Control
When low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 5Vrms. When high-level inputs are used, this control adjusts the input sensitivity between 1Vrms and 25Vrms.
Full on-board protection
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.
Class D amp technology
The JBL marine mono subwoofer amplifier delivers 600-Watts RMS using a Class 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.
INPUT Mode
MARINE A758 - Multiple switching: Switch to 2 Ch: To control RCA inputs from #1 and #2 channels:
- The audio signals from input #1 will be transformed to output #1, #3, #5 and #7;
- The audio signals from input #2 will be transformed to channels #2, #4, #6 and #8.Switch to 4 Ch: To control RCA inputs from #1, #2, #5 and #6 channels.
- The audio signals from Inputs #1 will be transformed to output #1 and #3;
- The audio signal from #2 will be transformed to Channels #2 and #4;
- The audio signals from Inputs #5 will be transformed to output #5 and #7;
- The audio signals from Inputs #6 will be transformed to output #6 and #8; Switch to 8 Ch: Each of all inputs are transforming its corresponding output #channel.
