Upscaling is the process of converting a standard definition (SD) video signal to a seemingly high-definition (HD) video signal by using a video scalar. Upscaling does not convert standard definition video to true high definition video, but it does dramatically improve the detail and colour consistency of the picture, up to 1080p, the resolution possible for HDTV. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal (display) resolution of 1920 lines and a frame resolution of 1920 × 1080 or over two million pixels. On AV Receiver video conversion from analogue level to the digital level for output via HDMI offers ease of use and best digital picture quality for each source material.
70% Power Guarantee
Marantz has the 70% power guarantee, meaning that a minimum of 70% of the stereo power indicated in the specification section will be available when 5 channels are simultaneously used. A lot of misunderstanding about power rating has been created by claiming the highest possible output power as a unique selling point. Measurement often has been done on only 1 speaker drive, with lower impedance than 8 ohms and high THD (total harmonic distortion) acceptance. A standard THD value is 0.08%. The lower the better.
Audyssey Dynamic EQ
Dynamic EQ selects the best possible frequency response and surround volume levels moment-by-moment. This ensures that the bass response, tonal balance and surround impression remain constant despite changes in volume. This is the first technology that carefully combines information from incoming source levels with actual output sound levels in the room, a pre-requisite for delivering a dynamic volume solution.
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.
DLNA certified products guarantee a stable and fast connection, cross-brand interoperatebility, Universal Plug and Play (UPnP), automatic IP-addressing and easy to use in a wired or wireless setup with your home network: Sharing of your favourite music, photo’s and video’s stored on your PC, NAS-drive, Musicserver or HD recorder through your audio/ video set-up is possible.
HDMI 4in 2out
HDMI combines high-definition video and superb audio in a single digital interface with a bandwidth of up to 10 Gigabits/ second. HDMI complies with High-bandwidth Digital Content Protection (HDCP) technology protecting high-value content from unauthorized reproduction and distribution. HDMI is the only interface in consumer electronics that can carry both high-definition video and multi-channel audio e.g. Dolby Digital and DTS in all HD formats, including 720p, 1080i and 1080p. With only a single cable connection all information can be digitally transmitted. The latest HDMI1.3 supports higher resolution audio formats as Dolby Digital Plus, Dolby TrueHD and DTS-HD and a higher bandwidth for higher framerates and extended degradation in colour space.
The use of compressed audio files like MP3, Windows Media™ Audio or AAC is getting more and more popular. The audio quality of these compressed files however is less than the original lossless files that are on a CD, especially lacking the higher frequencies and affecting the lower frequencies which make the audio image less wide and deep. The Marantz Digital Audio Expander, also called MDAX, recalculates the outputted frequency range of any compressed MP3, Windows Media™ Audio or AAC audio signal and expands it over a broader frequency range. This enables you to get a more detailed and clearer sound.
THX Select 2 / THX Ultra 2
THX certification, developed by LucasArts of George Lucas, is a quality assurance specification for products that meet the high requirements of THX, guaranteeing highest quality audio performance, and a soundtrack reproduction exactly as the audio engineers of the film intended it to be. THX certified products are build according the THX standards for presentation excellence, and include THX features as: timbre matching, bass management adaptive decorrelation, re-equalization (Re-EQ™) and Boundry Gain Control. There are two certification levels starting with THX Select2 and the even higher specified one THX Ultra2.
Toroidal transformer has several advantages over a normal EI core transformer. It is very efficient and therefore delivers more power compared to the same size of an EI core transformer. In addition, due to its shape, the electromagnetic radiation and the mechanical vibration are extremely low all ending in a better sound quality.
