In addition, Marantz has focused on the future. By utilizing pre-out jacks, 7.1 direct inputs and a RS-232C communication port, the SR7500 is tomorrow's technology, today! The SR7500 incorporates the latest in advanced Digital Signal Processing circuitry, along with a Crystal 192 kHz/24 bit D/A converter in each of the 7 channels. The SR7500 features a discrete, equal power amplifier section for all 7 channels, with superb low impedance driving capability and comprehensive dynamic reserve. A multi-zone function allows you to simultaneously enjoy a different entertainment source in another room. Complemented with an extensive programmable learning remote control, the SR7500 is the ideal choice in every home entertainment system. Performance to excite The SR7500 incorporates the most advanced 32-bit Digital Signal Processing circuitry decoding the latest generation of digital surround sound such as THX Surround EX, Dolby Digital EX, DTS ES, DTS Neo:6, Circle Surround II, and Dolby Pro-Logic IIx. The receiver provides an enveloping 7.1 channel playback of any multi-channel program, whether it's movie soundtracks or music, over the widest possible seating area. Latest surround technologies Pro Logic IIx is the first and only technology to process any native stereo or 5.1 signal into a 6.1- or 7.1- channel output. A product of Dolby's expertise in surround sound and matrix decoding technologies, Dolby Pro Logic IIx is a complete surround sound solution that maximizes the entertainment experience from stereo as well as 5.1-channel encoded sources. On playback systems with four surround speakers, the result is a more seamless, natural, and enveloping listening experience on everything from stereo music CDs to DVDs encoded in Dolby Digital Surround EX. Until now, processing stereo and 5.1 program sources into 6.1 or 7.1 output channels necessitated that the A/V receiver include a variety of decoders, often from different developers. In contrast, Dolby Pro Logic IIx decoding does it all, offering a single upgradeable solution for the home theater enthusiast who wants to go from 5.1 channels to 6.1 and 7.1. Dolby Pro Logic IIx technology features Movie and Music modes that function with 5.1 as well as stereo sources, including 24-bit/192kHz and 24-bit/96kHz sources. The Game mode restores the impact low-frequency surround effects by routing them to the system's subwoofer. Dolby Pro Logic IIx technology delivers a natural and immersing 7.1-channel listening experience to the home theater environment. Eight channel audio from any source Dolby Headphone technology allows users to listen to music, watch movies, or play video games with the dramatic surround effects of a 5.1-channel soundtrack through any set of headphones. Best of all, "listener fatigue," a phenomenon commonly associated with headphone playback, is replaced by a spacious, natural sound field that listeners can enjoy for hours. Surround sound headphone The SR7500 features a fully discrete 7 channel amplifier section capable of delivering 110 watts of high-current amplification, for continuously clean and stable power into each of the 7 channels. It employs a massive toroidal power transformer in combination with high grade oversized filter capacitors. Current Feedback amplification is a well known, Marantz original circuit technology accomplishments from the HiFi amplifier field. Due to the introduction of Super Audio (Super Audio CD, DVD-Audio) multi-channel software and an increasing amount of universal disc players, AV Receiver/ amplifier require a higher performance amplifier not only for digital surround sound from DVD Video via the digital input, but also for analog multi-channel. Even in the DVD Video world the amount of higher quality software increases with formats like DTS 96/24. The Current Feedback amplifier technology fits perfectly with the high requirements set for this 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. The SR7500 therefore 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 up to 100kHz. Current Feedback power amplification SR7500 is equipped with a high quality video conversion. It can up convert the Composite signal to S-Video/Component and S- Video to Component; as well as down conversion from S-Video to composite (the component signal is not down converted). This feature allows you to connect the best possible video cable between the SR7500 and the display and of course you only need one. In order to avoid synchronization and eroded video quality problems, the SR7500 has a high quality video converter equipped with digital video processing consisting of for example; 4H line memory, time based corrector, a triple 10-bit DAC, filed locking, VCR detection and anti aliasing filtering. The SR7500 provides you the highest analogue quality from all sources connected via a single component connection. Video conversion

Based on our room acoustics knowledge and expertise already shown in products like the AX1000 we have developed the Marantz Room Acoustic Calibration (MRAC). The algorithms developed are derived from this amazing AV computer developed more then a decade ago. Taking into account reflections from walls, ceiling and floor and knowledge about psycho acoustics, MRAC optimizes the sound for the room acoustics. The SR7500 is one of the first new generation Marantz receivers which is to feature the new MRAC function. With the supplied microphone placed on your listening position, the powerful DSP analyzes accurately and sets the sound configuration for your listening room. MRAC can tests and controls speaker configuration, trim, distance/delay and frequency response. The Marantz Room Acoustic Calibration achieves the ideal sound field for each and every room. Marantz Room Acoustic Calibration The strength of each Marantz design can be found in the attention to detail and cohesiveness of the different elements. The SR7500 is a clear example of benchmark engineering and craftsmanship and features a number of Marantz sound enhancements like Current Feedback topology amplification which makes the power amplifier in- sensitive to (difficult) loudspeaker loads. It incorporates leading edge digital signal processing, along with a Crystal 192 kHz/24 bit D/A converter in each of the seven channels. All of the digital, analogue and control circuits are separated and extensively shielded in their own enclosures to prevent cross-talk and other unwanted interference. Independent power supplies for the FL display, audio and video sections secure maximum separation, clarity and dynamics. Specially selected high grade components ensure the acclaimed Marantz sound quality. This design configuration is capable of a clear and powerful reproduction of the most demanding action movie soundtracks and full range (multi channels) music discs. Its ability to generate very high output voltages enables it to drive the most demanding speakers with optimum results. A touch of Marantz The digital processing and scaling of video displays can create a slight delay in the video signal. This delay makes audio tracks appear out of synch. Using sound delay you can slow the sound presentation to match the presentation of the video. The Sound Delay on the SR7500 adjusts in increments of 10ms steps from 0 –200ms. Matching audio and video The SR7500 is equipped with a multitude of Component terminals to connect your video source through the centre of your home entertainment. It provides one touch switching of video and audio source with a high quality reproduction and feeds useful information onto the screen via the user- friendly OSD. It features multi room/multi source, speaker A/B switching, 2 assignable DC triggers, 2 flasher inputs, a RS232c communication port, high grade - heavy duty - speaker binding posts and an extensive array of both analog and digital in-outputs. With 7 assignable digital inputs (8 in total), 4 component inputs, SACD Multi-Channel (7.1 channel) direct inputs, and a multi room speaker and OSD output versatility is taken to a new stunning level. With the Marantz audio system placed in the main room of the house, a second loud speakers can be placed at a separate room. In those rooms separately an audio source can be selected at a different sound level, even with full remote controlled functionality. Not only sound but even video signals can be handled in such a way that in the separate room a video source with OSD feature can be selected.
