The only player you'll ever need!

Featuring almost universal disc compatibility, the 751BD not only plays Blu-ray discs - including those with 3D content - but also CD, HDCD, DVD-Video, DVD-Audio and SACD.

Twin screen connection

With twin HDMI outputs, the 751BD can deliver video to multiple displays (such as a your 3D TV and your projector) and both are fully compatible with the HDMI 1.4 standard for 3DTV and Deep Colour support.

The primary HDMI output also features a high quality Marvell QDEO video scaler with motion adaptive noise reduction for quiet and natural video, free from noise and artefacts.

As well as stunning performance with Blu-ray discs, the 751BD delivers unbeatable picture quality from existing DVDs, which can also be up-scaled to 1080p resolution.

Comprehensive format support...

The 751BD supports decoding of the very latest formats including Dolby TrueHD and DTS-HD Master Audio. And for the ultimate in user choice, these formats can be output as bitstreams over HDMI for an AV receiver to decode internally.

An audiophile extravaganza...

However it is the 751BD's musical performance that really sets it apart from its peers with genuinely uncontested audiophile credentials. A mouth watering specification including five Wolfson WM8740 24-bit/192kHz Digital to Analogue converters, Anagram Technologies Q5 192 kHz upsampling, a choice of digital filters and zealous attention to the design of audio circuits ensures the 751BD can reproduce the dynamics and scale required for the most elaborate movie soundtracks. The 751BD truly excels as an audio source supporting all high-resolution formats including DVD-A, SACD plus of course CD.

Designed for all the family...

With such a vast specification you might expect the 751BD to take some getting used to but you'll be delighted to hear that's not the case. Genuinely simple to use with essential operations available on the ergonomic front panel and more comprehensive control via a clear on-screen menu, the 751BD is as easy to operate as any ordinary player. In use it's whisper quiet and lightning fast for delay-free access to your movies and music.

Aesthetics and premium build quality are further strengths and Cambridge Audio's trademark wrap-around casework houses the 751BD's proprietary engineering within a low resonance, acoustically damped chassis.

Supplied with a wireless dongle...

The 751BD is ready to connect to the internet via Ethernet or Wi-Fi and supports BD Profile 2.0 (BD-Live and BonusView) and other interactive features.

With an immense combination of multi-format capability, 3D video performance and spine-tingling audio capability, the 751BD is waiting to show you how Blu-ray can really perform!

Universal audiophile music and movie playback

We know how extensive many of your movie libraries are so a really important consideration when we developed it was the 751BD's ability to maximise performance of standard definition DVDs.

From the primary HDMI output, an onboard Marvell QDEO scaler with motion adaptive noise reduction and a host of other technologies offers huge gains in picture quality from all disc types.

In addition, the 751BD is equally at home with a wide array of other formats including CD, SACD, DVD-A, AVCHD and HDCD.

As well as universal disc playback, dual USB ports (front and rear) and a rear mounted eSATA port means you can also experience high definition video, photos and music from your external hard drives.

Mind-blowing video performance

A full range of HDMI, digital and analogue outputs offer connection to the widest possible choice of TVs, projectors and home cinema receivers.

All the latest surround-sound formats are supported and in particular, support for the true lossless Dolby True HD and DTS HD Master Audio formats provides unprecedented audio fidelity from Blu-ray discs. The 751BD is also capable of outputting all of these formats as bitstreams over HDMI for decoding in a suitable AV Receiver. Twin HDMI outputs allow older non 3D compatible AV receivers to be sent audio via one link whilst the 3D video is sent on the other to a suitable 3D display.

Video of up to 1080p resolution from BD discs at 50/60Hz or 24fps can be output over HDMI. The 751BD can also process DVDs to provide an upscaled 1080p output massively enhancing existing movie collections.

Audio dynamite

The 751BD is the ideal no-compromise choice for audiophiles who demand the ultimate audio reproduction with superb sonic performance as standard via two channel and multi channel outputs. Five dedicated Wolfson WM8740 DACs ensure every channel is decoded in the very highest quality and Anagram Technologies Q5 192 kHZ upsampling further enhances audio quality whether played from CD, DVD, Blu-ray or any other supported format.

If you're interested in reading more, further information on Q5 upsampling technology is available at www.cambridgeaudio.com/Q5

In addition to superb quality decoding, the ultimate in control is offered with a choice of digital filters. Linear phase, minimum phase and steep filters can all be selected to suit an individual's listening preferences.

And for the ultimate audiophile touch, select Pure Audio Mode and the 751BD shuts down all video processing to prevent any audio signal interference or degradation.

The 751BD again benefits from Cambridge Audio's rich musical heritage by supporting all high-resolution audio formats including DVDA and SACD. Both can be output via HDMI or using the 2ch or 7.1 channel analogue connections - the 7.1 connection in particular enables older, non-HDMI AV receivers to benefit from a new lease of life.

It's kinder on the planet too

Cambridge Audio takes its commitment to the environment seriously and as well as minimising power consumption in use, the 751BD boasts an environmentally friendly low power (<0.5W) standby circuit to help conserve precious energy...

Its beauty is more than skin deep...

A wrap-around all-metal casework - which matches Cambridge Audio's latest home cinema receivers - adds significant appeal and is augmented by a substantial brushed aluminium front panel. All this proprietary engineering is housed within a new low resonance, acoustically damped chassis featuring dual layer damped feet. The sum of these small but carefully considered details not only add to an aura of luxury, but help contribute to the 751BD's uncontested audiophile performance.

A highly ergonomic navigator remote handset also offers full control of the 751BD's wide range of features and functions and can be used to control virtually any Cambridge Audio home cinema receiver or amplifier.

ATF2 Upsampling in more detail…

751BD makes digital audio sound amazing – drawing detail seemingly out of thin air. How?

Our unique ATF2 (Adaptive Time Filtering) upsampling technology, developed in conjunction with Anagram Technologies, Switzerland.

logo-upsamplingAll incoming audio data, such as CD at 16-bit 44.1kHz CD, is upsampled to 24-bit 192kHz using a high-end 32-bit Analog Devices DSP (Digital Signal Processor). "Polynomial Curve Fitting Interpolation" provides a much more accurate upsampled audio soundwave than traditional upsampling processes. And a unique timing system buffers audio data to almost eradicate digital jitter. Vital – as jitter, common in digital audio devices, loses vital detail, often leaving digital audio sounding flat and lifeless.

 

 

Our latest ATF2 DSP also features a selectable digital filter with three settings to suit listener preferences and their particular system set-up: 

• The Steep roll-off filter exhibits strong attenuation of aliasing images outside the pass band (i.e. above 22.05kHz) at the expense of a little pre and post-ringing in the time domain. 

• The Linear phase filter uniquely features ‘constant group delay’ which delays all audio signals at all frequencies by the same amount meaning all audio is fully time-coherent at the output.

• Minimum phase meanwhile does not feature constant group delay but rather the co-efficients have been optimised without feed-forward so that the impulse response exhibits no pre-ringing in the time domain.

Firmware Updates

Click here for information about the latest firmware update
May 1st 2014

There is a new firmware update for the 751BD/651BD. The 751BD and 651BD use the same firmware. As such, the following update applies to both models.

- Region A (North, Central and South American and Southeast Asian countries plus Taiwan, Japan, China Hong Kong, China Macau and Korea).

- Region B (most European, African and southwest Asian countries plus Australia and New Zealand).

Features of the new update (version 751BD(CU)-15-0910) include the following:

- Improved BD disc compatibility with new releases such as “The Hobbit: The Desolation of Smaug”.

All features and improvements of previous firmware updates are also included in this latest version.

Note: playback of BDMV folders/files, ISO files and SACD-R is not supported due to copy protection laws.

The easiest way to update your player is to connect it to the internet, via the player’s Ethernet/wi-fi connection. The next time the unit powers up, the player will see that an update is available and will automatically prompt you to update the firmware for your 751BD/651BD (so long as firmware notification is ON in the Device Setup Menu). Alternatively, select Upgrade Firmware – Via Network, also within the Device Setup menu.

If it is not possible to connect your 751BD/651BD to the internet to update it, then you can also carry out the update via USB, following the instructions below. Please note the following; You must load only the correct region version for your 751BD/651BD. The 751BD/651BD is region locked for Blu-ray, and it is not possible to load the Region A update onto a Region B unit, for example.

Please first check the rear panel of your 751BD/651BD for confirmation of the player’s correct Blu-ray region – you will see A or B clearly marked within a hexagonal globe, just to the left of the mains inlet.

Important: Loading the incorrect firmware version may corrupt your 751BD/651BD. Cambridge Audio accepts no liability for an incorrect firmware version being installed. If you are at all unsure about carrying out the update yourself, please contact your dealer, who will be happy to update your 751BD/651BD for you.

Firmware version 751BD(CU)-11-0923 was released in September 2011. Features of this update included;

- Adds 8 kinds of OSD language
- Improves UPnP performance and USB browsing
- Improves CD performance and Blu-ray disc compatibility
- Improved the subtitle support in M2TS/TS playback through USB drive, external hard drive or UPnP streaming. Occasional reports that the movie picture could occasionally freeze up during the playback, while the time counter was still moving forward. This issue was related to subtitles and has been resolved in this release.
- Resolved the subtitle flickering or image stuttering issue during some 3D movie playback. Occasional reports of this happening randomly on some 3D movies released in Asia or Europe. Sample titles include "Step Up", "SAW" and "Resident Evil: Afterlife".
- Resolved the image vertical stretch issue observed on some legacy DVD's. Occasional reports of this happening when playing these DVDs using HDMI 1 and setting Aspect Ratio to "16:9 Wide/Auto", the pictures were vertically stretched. This issue could happen to certain 4:3 DVD's issued before or around 2000, and sample titles include "The Abyss", "Titanic", "TWELVE O'CLOCK HIGH (2002)" and "1941 (1979)".
- Improved support for user-created DVD-Audio discs. In the previous firmware, the on-screen display and the front panel time counters may stop at 00:00:00 when playback advanced from Track 1 to Track 2. This was mostly observed on user-created DVD-Audio discs which were “Audio Only” and contained no menus, backgrounds, or additional features.
- Resolved the Test Tone missing or harsh noise issues. Some customers have reported these using some special combinations of downmix mode and speaker setting.
- Improved the audio information display, e.g., previously "MLP 5.1" was shown as "5.1", "1/2 DTS 6.1" was shown as "1/2 DTS 5.1".
- Added brief chapter information (Current Chapter/Total Chapters) on-screen display when pressing PREV or NEXT button to skip chapters. This feature only applies to commercial discs which include Blu-ray, DVD and DVD-Audio.
- Further improved general disc compatibility based on recent and upcoming Blu-ray releases as well as user-submitted disc samples. Sample movies include "Avatar(3D)", "Journey to Mecca", "Alice (2009 Miniseries)" and "Pirate of Caribbean 4" (3D version released in Asia and Europe).
