Marantz MM7055 Black
Garantujemo najnižu cenu!
The Marantz MM7055 is a five channel power amplifier, that delivers a thumping 140W RMS into 8 ohm to each of the channels. While the ultra wide bandwidth current feedback technology easily handles the highest SACD frequencies, this also makes it ideal for the high definition DTS Master Audio and Dolby TrueHD formats too. The result being precise tonal and image balance, speed and dynamics. The unit also features XLR audio inputs, DC triggers and a Marantz control bus system for remote on/off. There is even a stylish new display screen showing the actual output power.
Current Feedback
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.
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.
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 it’s 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.
Power Supply
Linear drive power supply (LDPS) is Marantz own technology to design a power supply capable to follow all details of an audio signal to reproduce the finest sound quality.
