MARANTZ MM7055
Den nya MM7055 är femkanalsalternativet i årets utökade förstärkarprogram. Den bygger på den teknik som används i MM8003 och har precis samma chassi. Uteffekten är dunkande 140W RMS i 8 ohm till var och en av kanalerna, medan en ultra-bred bandbredd och current feedback-teknik enkelt hanterar de högsta SACD frekvenserna - idealiskt för High Definition DTS Master Audio och Dolby TrueHD-format. Resultatet? Både tonalitet och ljudbild i exakt balans, snabbhet och dynamik. Och till på köpet får du också XLR ljudingångar, DC triggers och Marantz' styrsystem för fjärrstyrning på/av. Detta är kraft och enkelhet som kommer att ta andan ur dig.
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 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.
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.
