Power Marine 750 Watt Class-bd 1-Channel Amplifier TM750X1bd

The TM750X1bd Element Ready amplifier is a 750 watt RMS, 1 ohm stable unit built on out Class bd platform for maximum sound fidelity and efficiency. It also integrates out Constant Power technology which results in up to 25% more output power. Amplifier top mounted controls include our C.L.E.A.N. level setting system, integrated low pass crossover and our Punch EQ boost circuit. Upgraded input RCA connectors allow for high or low level input signal to be used through our differential input circuit which eliminates incoming noise and can provide a remote out signal when using high level inputs. Dual fan cooling, real time thermal monitoring and dual extruded heat sinks maintain heat dissipation even at high outputs keeping the amp cool. Other features include a conformal coated circuit board for protection against element exposure and compatibility with our PLC2 level remote control.

Overview

The Power TM750X1bd 750 Watt mono, ultra-compact amplifier is built on Rockford Fosgate’s patented Class bd technology platform. This design creates a highly efficient design that reduces the electrical impact on the vehicles charging system by using the efficient Class D technology while maintaining fidelity combining it with Class b topology. Flexible vehicle integration is achieved via a configurable input harness with Molex style connectivity that accepts both RCA and speaker level signals while our differential input circuitry eliminates signal noise from entering the amplifier resulting in a clean audio signal.

When using speaker level input signals, the amplifier also has integrated auto turn-on capabilities and converts its remote input terminal to an output that can be used to turn-on additional amplifiers. This can eliminate the need of sourcing a separate remote turn-on signal for the amplifier from the vehicle. Top mounted controls allow easy access to the built-in low pass crossover, patented Punch EQ boost circuit and our patented C.L.E.A.N. input/output clip detection circuits.

The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while our real-time thermal/protection schemes safeguard the amplifier in the event of overheating or short circuit conditions. The unit is also compatible with our Punch PLC2 remote level controller and is ideal for those installations where you need a compact amplifier that can produce high output power.
