The MM7025 is an ideal two-channel power amplifier with whopping 140W RMS into 8 ohms per channel. Use it in an AV setup to give your front channels an earth-moving boost or in combination with a HiFi Pre-Amplifier to create a high quality 2 Channel System. Current Feedback Current Feedback amplification is a well known, Marantz original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads. Customized Components On paper an electrical component might look excellent but the result may fall short of the combined design expectations. Marantz selects the appropriate components for the specific design application. In some cases its simply not possible to use standard components that meet the high Marantz standards. These components will then be specially made for Marantz in close cooperation with the Marantz engineers. DC-Trigger A DC trigger is an assignable voltage output which can automatically control for example an electrical projection screen, lowering it when the DVD input is chosen on the receiver. IR Flasher IN The IR-Flasher IN is a standardized connection to control the AV system by external IR receivers independent of the infra red control format used. On the IR-Flasher OUT an IR-Emitter can be connected to controlled third brand components. The third connection link to this is the IR-Receiver INPUT which is similar to the IR-Flasher In, but it outputs a voltage to directly feet an external IR-Receiver eye. Please check capability per product in the specification section. Linear drive power supply LDPS Marantz own technology to design a power supply capable to follow all details of an audio signal to reproduce the finest sound quality.
Designed as the perfect Partner to the Marantz AV8802A processor it,s 7 channels deliver 150W (8 ohm) of RMS power (20Hz-20kHz).
