请教-----Lexicon 的 MC-8

汤米

M C8很少人使用.只能听了再说.这么贵的东西 不能想当然.

木的问题,绝对值.就算买了当纯多声道前级用.............

AIKAI

MC8是纯前级，才3800美元？
RV4有这个型号吗？我记得是RV8啊！

COOLCOOL

其实还有个MC4可以考虑啊!虽然是小弟,但好歹是LEXICON的小弟.如果在3W大米以下.玩5.1绝对是可以了.反正现在DVD-A和SACD都只有5.1.后级也是5声道的居多.

惺惺相惜

以前听过两次用MC8的展示会,没感还行
推了那边,还是自己去HK买算了.好歹能试能验.万一坏了拿下去修也不太难.
如果真能达到2万级的HIFI前级质素就上一个.

看它背面也真够OUT的,视频只有Y/C和S端子.
不过最喜欢它的两组5.1 IN.使我可将DVD-A和SACD分开两台机了

MC-8的介绍
=====================
Value
Equipped with 2 independent zones, 8 configurable inputs, and 8 channels of output, the MC-8 is ideal for all but the most elaborate systems.With fewer rear panel connectors and one less zone than the MC-12, the MC-8 is physically smaller and more affordable. Drawing on Lexicon’s legendary expertise in digital audio, the MC-8 offers superior performance and value for today’s music and home theater enthusiast.

Balanced
The MC-8 Balanced includes balanced audio outputs for all channels, including Zone 2. In many installations, the Digital Controller is located in an equipment rack along with tuners, satellite receivers, and so on which can introduce audible interference into the system. By using balanced audio connections between the digital controller and the power amplifier, the potential for audio interference is minimized. For systems utilizing amplified speakers, balanced connections will eliminate noise introduced on cables between the digital controller and speakers.

Powerful
At the heart of the MC-8 are four Analog Devices SHARC digital signal processing engines, one Cirrus Logic DSP engine, and ten 24-bit/192kHz digital-to-analog converters - an architecture that is nearly identical to the MC-12. As a result, the MC-12 and MC-8 share the same tremendous processing power and sonic soul.The MC-8 includes THX Ultra2 certification and dts 96/24 decoding, rounding out its impressive list of playback technologies: Dolby Digital EX, Pro-Logic II, dts-ES, dts Neo:6, and LOGIC7.

LOGIC7
The MC-8 features Lexicon’s decoding technology:
LOGIC7. Based on years of psychoacoustic research, LOGIC7 strikes a delicate balance between channel separation and surround envelopment. For music, film, and broadcast sources, LOGIC7 distinguishes between primary and background signals and processes them appropriately. Prominent sounds like a singer’s voice or an airplane’s roar are reproduced with stunning clarity. The signal is sent to the appropriate speaker with high channel separation, while secondary sounds like the ambient noise of a concert hall or the great outdoors are reproduced with amazing spaciousness. With LOGIC7, the listener experiences an unmatched sense of involvement.

Connected
With formats such as DVD-Video, DVD-Audio, Super Audio CD, and High-Definition TV, the demand for input connectors has grown. The MC-8 provides compatibility with these formats, offering 3 component video inputs and 8 configurable analog inputs. The analog inputs can be configured as; 8 stereo inputs, 5 stereo inputs plus one 5.1-channel input, or 2 stereo inputs plus two 5.1-channel inputs for separate DVD-A and SACD sources.

Expandable
Like the MC-12, the MC-8 provides the ability to easily upgrade its software via a rear panel RS-232 port. The MC-8 also features 2 internal upgrade slots and 2 rear panel access plates, which provide the ability to augment the rear panel connections should upgrades be made available by Lexicon.

Simple
The MC-8 uses the same intuitive on-screen menu system and user interface as the MC-12 for navigation of the set-up options and features. Both new users and those that are familiar with Lexicon digital controllers will instantly feel at home with the MC-8 and will be fine-tuning it in minutes.

Conclusion
Designed with a careful balance of performance and function, the MC-8 is sure to impress with its stellar performance, simple user interface, set-up flexibility, and expandability. Combined with a RT-10 disc player and a LX series power amplifier, the MC-8 serves as the core of a high performance, high value home theater system.


这个MC4好象也不错
===================
Based on the reference MC-12, the MC-4 Digital Controller is perfectly suited for less complex multi-channel systems in which sound quality, picture quality, ease-of-use and reliability are still of paramount importance.

8 channels, 8 configurable inputs
Up to two 5.1-channel analog audio inputs
Analog bypass available for stereo and 5.1-channel analog audio inputs
S/PDIF coaxial and S/PDIF optical digital audio inputs
Automatic switching between analog and digital audio inputs
24-bit/192kHz D/A converters
Stereo side and rear outputs and a dedicated subwoofer output
2 broadcast-quality video switchers
3 component video inputs with full HD-TV compatibility
5 S-video and 5 composite video inputs
4 32-bit, floating-point DSP engines
Separate DSP engine to decode Dolby Digital and DTS signals
LOGIC7&reg; decoding
Dolby Digital Surround EX and Dolby Pro Logic II decoding
DTS 96/24, DTS Neo:6, and DTS-ES (matrix and discrete) decoding
THX Ultra2 and THX Surround EX decoding
2 trigger outputs
Rear panel IR input
RS-232 control
Rack-mount option

關於MC-12的生命期
[節錄自SMR討論]
MC-12 life span - As you all know we provide updates/upgrades for the MC-12 to continue to improve the performance and provide the market with high performance features. As new technologies arise and new features become available we will work to provide those to you in the form of these upgrades and updates. In keeping with Lexicon tradition and business practice, when the MC-12 can no longer be updated we will provide trade-in/ update programs that will allow MC-12 owners the opportunity to move to the new platform. This has been done in that past as you are all aware and will happen in the future.

也是约3万,美,台网站很多人讨论


Film or music, digital or analog, processed or direct, the Sunfire never sounds less than good. It generates an awesome sense of space, yet will precisely pinpoint details within that space." The Perfect Vision

"While the Theater Grand's front panel is impressive, it's the back panel that's the real winner here. You'll find connectivity and intelligent routing for practically every component you could possibly own…" E-Gear Magazine

Since Bob Carver's entry into the home theater A/V preamp market years ago with the highly-acclaimed and award winning Sunfire Theater Grand, Bob and his team have kept busy cooking up new ways to improve the design. The amazing Theater Grand II and III that followed were huge successes; the new version IV adds even more features and new styling.

Like its predecessors, the Theater Grand IV is foremost an audiophile-grade preamplifier. Bob and his team designed it to produce a warm and engaging soundstage - both your movie and music soundtracks will be smooth and dynamic.

The Theater Grand IV adds Dolby&reg; Pro Logic&reg; IIx to its array of numerous surround modes including Dolby&reg; Digital, Dolby&reg; Digital EX, DTS&reg;, DTS-ES&reg;, DTS Neo:6&reg;, and user-configurable all-speaker stereo. It also includes an incredible digital implementation of Bob's wildly successful Sonic Holography&reg; Imaging, that substantially adds to the acoustic space of any stereo recording.

The Theater Grand IV's control system takes into consideration the needs of the modern AV system. New in version IV is video format conversion that automatically up-converts composite to S-video, and S-Video to component video to keep you from having to change inputs on your TV.

The Theater Grand's remote is a powerful preprogrammed and learning LCD-based design that is easy and intuitive for your family to operate. The Theater Grand IV includes an RS-232 communication port to allow easy operation from any custom control system, as well as an IEEE-1394 (Firewire™) port for future expansion.

If your eyes get tired, the Theater Grand also includes an AM/FM tuner with 40 presets, an 8-channel input for DVD-Audio or SACD, eight balanced XLR outputs, a Phono stage, and much, much more.
