Marantz je proizvođač i distributer visoko kvalitetne audio opreme. Prvi proizvod je projektovao i napravio Saul B. Marantz u Kew Gardens-u, New York. U to vreme, kompanija je imala veliki uticaj na razvoj Hi-Fi audio-sistema, obraćajući pažnju na svaki detalj pri projektovanju i konstruisanju. Sredinom 1980-ih dok je bio pod rukovods-tvom Philips-a (pionira u CD tehnologiji), Marantz je među prvima pravio CD plejere koji su jako dobro prihvaćeni od strane zadovoljnih potrošača i kritičara. Danas, Marantz nastavlja da pravi komponente koje su u samom vrhu Hi Fi ponude na tržištu. O tome svedoči i Ken Ishiwata bez čije kontrole i finalnog tjuniranja nijedan Marantz proizvod ne može da se pojavi na tržištu. Godine 2002, Denon i Marantz prave (D&M) grupu kojoj se kasnije priključuju i druga zvučna imena iz audio industrije. |
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.
