Note: This unit supports the playback of both NTSC & PAL
Blu-ray Disc Overview: Blu-ray Disc (BD) is a new
high-definition disc format designed to take advantage of today's high quality
HDTVs. The resolution is up to 1920 x 1080 (1080p) and the data transfer rate is
up to 54 mbps. Blu-ray Disc discs and players offer several advantages over the
standard DVD format:
- Better Picture Quality: Blu-ray Disc is a true
high-definition format offering video at 720p, 1080i, or 1080p resolution.
While standard DVDs look very good on an HDTV, they don't provide a
high-definition signal (not even when you use an up-converting DVD player).
Blu-ray Disc delivers an extraordinarily sharp, clean, detailed picture,
with deeper, richer colors.
- Better Sound Quality: In addition to the same
multi-channel sound formats you're accustomed to with DVD (Dolby Digital and
DTS), Blu-ray Disc offers Dolby TrueHD, Dolby Digital Plus, DTS-HD Master
Audio, DTS-HD High Resolution, and uncompressed 7.1 channel PCM.
- Greater Storage Capacity: What makes Blu-ray Disc's
superior picture and sound possible is the much higher storage capacity of
Blu-ray Disc discs. A single-layer Blu-ray Disc can hold 25 gigabytes of
data, over five times the amount a standard DVD can hold. Dual-layer Blu-ray
Discs hold 50 gigabytes, which equates to nine hours of High Definition or
23 hours of Standard Definition video, plus high-resolution multi-channel
audio and the added features and material that require multiple discs with
- Backward Compatible: To ensure backward-compatibility
with your existing library of discs, Blu-ray Disc players use a dual-laser
mechanism: a blue laser for playing high-definition Blu-ray Discs, and a
conventional red laser for playing DVDs and audio CDs.
Note: Like DVD, BD uses region codes. The region code on
your disc must match the region code on your player, otherwise the disc will
not play. The 751BD is Blu-ray region A and DVD region 1. Blu-ray Disc uses
the Advanced Access Content System (AACS) to prevent unauthorized recording
Firmware Updates: As Blu-Ray technology continues to evolve,
new disc types with enhanced functionality will become available. In order for
you to enjoy this new functionality, you will likely be required to update the
firmware in your player. These firmware updates will become available for
downloading from the Internet, via the player's Ethernet port.
Note: The tested
Blu-ray player contained firmware version 751BDCU-10-0721 and required an
immediate firmware version update (as of 7/12/2012). Visit Cambridge Audio's
Support Site for the latest firmware updates.
AVCHD Playback: The 751BD will play home videos recorded in
AVCHD (MPEG-4 AVC/H.264), a high definition digital video camera format used to
record in high definition or standard definition on DVD-R/RW or DVD+R/RW discs.
AVCHD can also be played from a USB flash memory device connected to the front
SACD: Super Audio CD use a technology called Direct Stream
Digital (DSD) to convert music into a digital signal that can be stored on a
disc. Compared to the traditional PCM method (the technology used for CD), DSD
offers a much higher resolution by following more closely the original waveform
of music. With a frequency response of over 100kHz and a dynamic range over
120dB across the audible frequency range - some 64 times higher resolution then
CD - Super Audio CD offers music reproduction that reveals details you just
cannot hear on a normal CD.
DVD Audio: DVD Audio is a digital audio format that delivers
high-fidelity audio content on a DVD disc. DVD-Audio supports bit depths up to
24-bit and sample rates up to 192 kHz, while CD audio is only 16-bit, 44.1 kHz.
Compared to CD audio discs, DVD Audio offers considerable more music storage,
higher audio quality, and additional audio channels for surround sound.
DVD-Audio offers many possible configurations of audio channels (up to
5.1-channel surround sound).
HDCD: HDCD is a variation of the existing CD standard. By extending
the information stored in the CD signal by 4-bits (CDs are based on 16-bit audio
technology) to 20-bits, HDCD can extend the sonic capacity of current CD
technology to new standards.
Kodak Picture CD: This unit can also play JPEG files stored
on a Kodak Picture CD; you can enjoy pictures on the television by playing back
MP3/WMA Playback: The Cambridge Audio Blu-ray player will
play MP3/WMA audio files written to CD-R/RW, DVD-R/RW, and DVD+R/RW discs.
Video Outputs: The Cambridge Audio 751BD is equipped with
the following high-definition and standard definition video outputs.
- Dual HDMI 1.4a Outputs: With twin HDMI outputs, the 751BD can
deliver the same video signal to two display simultaneously. Both HDMI
outputs are fully compatible with the HDMI 1.4 standard for 3D, Deep Color,
& xvYCC support. The HDMI outputs support 480i, 480p,
720p, 1080i, and 1080p.
- Component Video Output: The 751BD features one
component video output, capable of passing a progressive scan signal or an
interlaced video signal. The component video output supports 480i, 480p,
720p, and 1080i.
- Composite Video Output: The Blu-ray disc player
features one Composite video output that supports 480i.
1080p/24Hz Compatible: Movies are typically recorded on film with a
frame rate of 24 frames per second. When a movie is transferred to Blu-ray Disc
at 24 frames-per-second ,the 751BD will output that signal to the TV (if the TV
will accept the 1080p/24 format) with no need for conversion.
Marvell QDEO Video Scaler: The primary HDMI output also features a
high quality Marvell QDEO video scaler (DE2750) with motion adaptive noise
reduction for quiet and natural video, free from noise and artifacts. As well as
stunning performance with Blu-ray discs, the 751BD delivers unbeatable picture
quality from existing DVDs, which can be up-scaled to 1080p resolution.
Note: Video up-conversion over the component output
is only available for unencrypted discs such as home video and
consumer-created contents. Most commercially pressed DVD discs are CSS-encrypted
and will be limited to 480i/480p resolution. This restriction applies to the
component output only. The HDMI output is protected with HDCP and has no
Source Direct: The 751BD supports a special "Source Direct"
output resolution on its HDMI output. This resolution is recommended for use
with external video processors or high-end TVs with high quality scalers. In
"Source Direct" mode, the player works as a "transport". It decodes video from
the discs and then sends the raw video signal in its native resolution and
format, without extra processing, to the external video processor or TV. The
actual output resolution thus varies by content.

|SACD or DVD-Audio
3D-Ready: The Cambridge Audio 751BD lets you enjoy 3D
Blu-ray disc movies in full HD 1080p. 3D viewing requires compatible 3D content,
3D-ready HDTV, 3D emitter & glasses, and a high-speed HDMI cable (supporting at
least 10.2 Gbps) connection. The Blu-ray player offer three 3D video output
- Auto: Outputs 3D if supported both by the disc content and the
display. The player automatically checks for the existence of 3D content on
the disc and the 3D compatibility of the TV or projector. If both are
qualified, the player sends 3D video from its HDMI output terminals,
otherwise only 2D video is sent out. 3D-compatible glasses are
required with your 3D TV.
- Forced: Always outputs 3D video format for 3D Blu-ray discs. You
might experience a black screen (no video output) if your TV is not 3D
- Off: Always outputs 2D video format, even when 3D video exists on
the disc. This can guarantee the video quality in case that your TV is not
3D compatible, or some necessary part (such as the 3D glasses) is missing.
Note: You can also set the diagonal screen size of your HDTV.
Deep Color: The HDMI output supports Deep Color, increasing the number
of bits available for transmission, meaning more colors. This results in much
greater color fidelity, smooth tonal transitions, and ultra-fine gradations
between colors. It also enables many times more shades of gray, for higher
xvYCC: xvYCC color space reproduces a greater range of color
than before, showing almost all of the colors that the human eye can detect.
Aspect Ratio: Use this setting to select the screen format to fit your
- 16:9 Wide/Auto: 16:9 (widescreen) as well as 4:3 sources will be
displayed in their native aspect ratio. Please note that in this mode 4:3
sources will be displayed with black borders on both sides to maintain the
correct 4:3 aspect ratio.
- 16:9 Wide: Select this screen when connected to a 16:9 widescreen
TV set. The full picture will now normally be displayed with no picture
cropping (unless the movie itself has black bars recorded into the video).
- 4:3 Letter Box: You can select this screen when connected to a
4:3 TV set. The full widescreen picture is displayed on the screen with
black strips on the top and bottom of the screen
- 4:3 Pan & Scan: You can select this screen when connected to a
4:3 TV set. The widescreen picture will display on the full screen, but some
parts of the video picture will be cut off automatically.
Picture Adjustment: You can adjust the player's picture control
parameters and save up to three custom picture modes. You can adjust the
- Brightness: Adjusts the brightness (black level) of the video
- Contrast: Adjusts the contrast (white level ) of the video
- Hue: Adjusts the hue (tint) of the video output.
- Saturation: Adjust the saturation (color intensity level) of the
- Sharpness: Sets the images sharpness (Detail/Edge Enhancement) of
the video output.
- Noise Reduction: Applies video noise reduction processing to
- Color Enhancement: Enhances certain colors in the spectrum of the HDMI 1
- Contrast Enhancement: Expands the details in the shadows on the
HDMI 1video output.
Five Wolfson (WM8740) 24-bit/192kHz DACs: Five Wolfson WM8740
24-bit/192kHz Digital to Analog converters ensure the 751BD can reproduce the
dynamics required for the most elaborate movie & music soundtracks.
Anagram Technologies Q5 192kHz Upsampling: The Cambridge Audio 751BD
employs Anagram Technologies Q5 192 kHz upsampling. Q5 Upsampling allows digital
audio signals from virtually any audio source to be resampled, resynchronized
and retimed to extraordinary levels of detail. In effect, upsampling the digital
data stream (up to 192kHz) allows existing "standard" CDs and DVDs to have the
enhanced audio clarity, richness and dynamic range that would normally be
associated with SACD or DVD-Audio discs. missing. Three proprietary
anagram technologies are included in Q5. These technologies effectively reduce
noise artifacts caused by imperfect digital systems and allow the digital signal
to closer represent the true analog sound of the studio mastered audio data.
- Adaptive Time Filtering: Adaptive time filtering allows the
system to adapt to small fluctuations in the systems audio master clock. The
master clock is the heart of any digital audio system, however as all
components that are constructed from physical materials, they will at some
point in time deviate from their ideal generalized behavior causing, in this
case variation in frequency and system jitter in this important internal
timing reference. Typically these variations will not be corrected for,
however in Q5 enabled devices the system automatically adapts to these small
fluctuations resulting in perfect "glitch" free analog sound even after
endless hours of continuous playback.
- Data-to-System Synchronization: Data-to-System synchronization
allows any incoming audio stream to be resynchronized and retimed to a local
high quality clock. By using a stable clock reference, the negative effects
of inter-component jitter can be minimized. When converting the digital
audio to an analog signal through high performance D/A converters, this
reduction in jitter has enormous benefits in the level of detail and clarity
in the reconstructed analog sound.
- Innovative Virtual Time-Domain Model: Combing these processes
with a virtual time domain model that uses an advanced cubic interpolation
algorithm to resample the incoming audio data, timing errors in this signal
can be compensated for at amazing levels of accuracy. The end result is
tighter, more focused bass, increased stereo imaging, focus and separation
for all musical instruments and voices.
Digital Audio Formats: The latest surround-sound formats are supported
including decoding of Dolby True HD, Dolby Digital Plus, DTS-HD Master Audio and
DTS-HD High Resolution Audio in Stereo, 5.1 or 7.1 variants. In particular
support for the true lossless Dolby True HD and DTS HD Master Audio formats
provides unprecedented audio fidelity from Blu-ray discs

Pure Audio Mode: You can enjoy higher quality audio by turning off the
video processing and output. The Pure Audio mode reduces any potential
interference between the video and audio signals
Phase Filter Select: The 751BD employs
Cambridge Audio's own proprietary digital filter algorithms with three different
filter options available - Linear Phase, Minimum Phase, and Steep. Controlled
from one switch on the front-panel, they are extremely clever audiophile
topologies specifically developed for audio playback and all offer excellent
sound quality, but differ slightly to appeal to a wide range of listening
- Linear Phase Filter: The Linear Phase Filter is the
same as used in Cambridge Audio's flagship Azur 840C upsampling CD player.
It 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 Filter: The Minimum Phase Filter does not
feature constant group delay, but rather has been optimized without
feed-forward so that the impulse response exhibits no pre-ringing in the
time domain. Many audiophiles have argued that the pre-ringing, as seen in
nearly all digital filter designs, may affect the transient attack of
percussive instruments. Minimum phase implementation eliminates this and is
a technology only seen previously in some extremely high-end CD playback
- Steep Filter: The steep filter removes
undistinguishable artifacts via re-calibration for a very slight roll-off at
20kHz, but an ultra-steep drop to the stop-band just after 20kHz.
Audio Outputs: The Cambridge Audio 751BD is equipped with
the following analog and digital audio outputs.
- Digital Audio Output: This unit features a coaxial
(RCA) and optical (toslink) digital audio output connection. The coaxial or
optical digital audio output can be connected to an A/V receiver, amplifier,
surround decoder (Dolby Digital, DTS), or other component. The digital audio
outputs support transfer of Dolby Digital and/or DTS sound tracks, or
down-mix surround bitstreams to 2-channel PCM audio.
- Analog Multi-Channel Audio Output: The 751BD offers a built-in Dolby
Digital /DTS decoder with multi-channel analog outputs (7.1ch).
- 2-Channel Output: In addition
to the 7.1-channel analog outputs, the unit features a dedicated stereo audio output
for connecting to a stereo analog input on a TV or receiver. Even when the
source audio is multi-channel (Dolby Digital, DTS, DVD-Audio, SACD), these
jacks will output a downmixed 2-channel signal.
Speaker Management: In the Speaker Management menu you can configure
speaker settings such as down-mix mode, number of speakers, their distance,
size, trim level, and crossover frequency.
- Configuration: Choose from Down Mix (converts multi-channel audio
to a lesser number of channels), LT/RT (the center and surround channels are
decoded and then matrix encoded into the two front channels), Stereo
(down-mixes multi-channel audio to 2-channel stereo), 5.1ch (enables 5.1ch
decoded audio output), or 7.1ch (enables 7.1ch decoded audio output).
- Size: The speaker size parameter sets bass filter control for the
speakers. Choose Large or Small for your speakers and On or Off for your
- Crossover: When the speaker size is set to "Small", bass
frequencies are not passed to the speakers to reduce possible distortion:
bass frequencies will instead be redirected to the subwoofer. The available
options are 40, 60, 80, 90, 100, 110, 120, 150, 200, and 250Hz.
- Distance: The speaker distance parameters sets delay control for
the corresponding audio channel. This delay is used to compensate for the
audio propagation time difference caused by the placements of speakers of
different distances from the listening position.
- Trim: The speaker trim level parameters sets the volume of each
individual channel. For most accurate results, it is recommended that you
use test tones from a calibration disc, such as Digital Video Essentials HD
Basics, and a SPL (Sound Pressure Level) meter. The trim level can be set to
+/- 10dB in 0.5dB increments.
Dynamic Range Control (DRC): DRC can smooth out the sonic peaks and
valleys common with wide-range digital audio. Enabling DRC may make low level
audio more audible during low-level listening. Turning off DRC restores the
sonic energy present in the original recording.

Easy Setup Wizard screen will appear. This is a series of guided instructions
designed to configure the basic settings for the unit.
Multi-Disc Resume: The player automatically remembers the current
position for a disc when playback is interrupted. Operations such as Open/Eject
or turning Power off will cause the player to save the current playing position
for that disc. The position is memorized even after turning off the unit or
changing the disc. When the next time the same disc is played back, the player
will recognize the saved playing position. Playback will automatically resume
from this saved position. However if you wish to cancel the automatic resume and
start playback from the beginning, you may press the STOP button when prompted.
The player can remember playback position for up to five discs. When the sixth
disc is memorized, the oldest one is replaced.
Note: Some Blu-ray discs do not support resuming and
will always play from the beginning.
Parental Controls: Some movies contain scenes that may not
be suitable for children to view. Many of these discs contain parental control
information that applies to the complete disc or to certain scenes on the disc.
Movies and scenes are rated depending on the country. Some discs offer more
suitable scenes as an alternative. Parental Control allows you to set a rating
limit (DVD: Kid/G/PG/PG-13/PGR/R/NC17/Adult/Off, BD: 1-12), preventing your
children from viewing inappropriate material. Playback will stop if the ratings
exceed the levels you set, and it will require your to enter a 4-digit password
before the disc will play back.
