Audio Features

Audiophile Components: The Cambridge Audio azur 351R employs a Toroidal transformer and isolated processing boards for a high purity, low-distortion signal. The AV receiver's X-Tract near-silent cooling system combined with a rigid low-resonance chassis maximizes the system's audio signal quality.

5 Discrete Amplifiers: Seven discrete amplifiers driven by a low-flux toroidal transformer are separated from the processing and input stages delivering ultra-low noise and distortion, thereby guaranteeing performance without compromise. This careful design of the amplifier stages ensure that the 351R can reproduce the dynamics required for movie and music soundtracks. The 5 channel amplifier is rated at 70 watts with 2 channels driven (1kHz, 8-ohms, 0.006% THD) or 50 watts with all 7 channels driven (1kHz, 8-ohms, 0.006% THD).

24-bit/192-kHz DACs: The Cambridge Audio azur 351R utilizes a 192 kHz/24 bit D/A converter on each of the unit's seven channels for exceptional sound quality. The 192kHz sampling and 24-bit word length capabilities of the DACs allows you to play high-resolution recordings and hear the increased clarity, detail and dynamic range of those recordings.

Dual 32-Bit DSPs: The Cambridge Audio azur 351R employs Cirrus Logic dual 32-bit DSPs for compatibility with the latest Dolby Digital/DTS formats, Dolby Pro Logic/DTS Neo:6 surround processing, and Dolby Pro Logic surround processing.

• Dolby Digital: Dolby Digital, Dolby Digital Plus, Dolby TrueHD
• DTS: DTS, DTS-HD Master Audio, DTS-HD High Resolution, DTS 96/24, DTS Neo: 6
• Dolby Pro Logic: Dolby Pro Logic II

Matrixed Surround Modes: These modes allow a surround-sound experience from source material that has no encoding at all. The surround sound effect is achieved by digital signal processing of the analog or digital stereo source used. Five modes are possible; Movie, Music, Room, Theatre, and Hall.

Stereo Modes: The surround receiver also provides two-channel stereo playback, as well as an analog stereo direct mode.

• Stereo/Stereo + Sub: Only the front left & front right speakers (and subwoofer if selected) have output in this mode. If an analog source is selected, it will be converted to digital via 24 bit A/D converters to allow digital domain sub creation and bass/treble controls. If a digital source is selected, the 351R will be processing either LPCM stereo (from the digital outputs of a CD player for instance) or a Stereo downmix of DD or DTS material (from the digital output of a DVD player for instance).
• Analog Stereo Direct: Selects the analog inputs for the current source directly with no A/D conversion, DSP processing, Bass/Treble, or subwoofer channel active. Provides the very best fidelity for analog Hi-Fi source equipment. In this mode the 351R is acting just like a normal Hi-Fi integrated amplifier.

Dolby Pro Logic II Music Settings: While listening in the Dolby Pro Logic II Music format, there are three further enhancements you can adjust.

• Panorama: A Prologic II mode that extends the front stereo image to the surround sound speakers for a more enveloping experience. This mode can be either On/Off.
• Dimension: Allows gradual adjustment of the center image from being produced only by the Center speaker (Setting 0) through levels of being spread between the center channel and left and right speakers to finally being produced by the front left and right speakers only (Phantom Center, Setting 7). Useful in optimizing the front/center/right soundfield for best integration of the three speakers.
• Center Width: Adjusts the soundfield to be gradually shifted from the front of the room to the back to suit taste, speaker positioning, and size of room. Setting 0 has the image furthest forward, 6 furthest back.

CAMCAS (Cambridge Audio Microphone Controlled Auto Setup): Cambridge Audio's Microphone Controlled Auto Set-up (CAMCAS) tailors the 351R 's performance to any room and comes complete with a microphone to complete this simple procedure. The CAMCAS system performs two sets of tests; first checking which speakers are connected and whether they are wired correctly and in phase, then second automatically measuring and adjusting the speaker delay timings and levels. You can also choose to manually setup the receiver's speakers settings.

Individual Crossovers & Advanced Bass Management: The azur 351R provides individual crossover adjustments and advanced bass management settings.

• Tone Controls: The azur 351R offers independent Bass (100Hz) & Treble (10khz) adjustment from -10 to +10dB.
• Speaker Crossover: Each speaker (front/center/surround/surround back) and subwoofer crossover point can be adjusted from 40-150Hz (in 10Hz steps) and also to 200Hz.
• LFE Trim: The LFE channel (for DD/DTS material) can also be trimmed by up to 10dB (in 1dB steps); useful for late night listening or other situations where it might be desired to reduce the low frequency effect level temporarily.
• Bass Augment: You can select whether to play front channel low-frequencies through either the front speakers or the subwoofer, or through both the subwoofer and front speakers.

Dynamic Range Control: This setting controls the dynamic range of Dolby Digital movie soundtracks by compressing the audio to limit the difference in level between loud and quiet passages in the movie. The receiver's Dynamic Range Control can be set to Auto, On, or Off.

Audio Inputs/Outputs: The AV receiver offers a variety of analog and digital audio inputs/outputs.

• Digital Inputs: The azur 351R features one digital optical input and two coaxial digital inputs.
• Binding Post Speaker Terminals: The receiver has binding-post terminals for all speaker connections. The binding-post terminals can accept bare wire, pin connectors, and banana plugs (single only). Speakers with an impedance of between 4-8 ohms are recommended.
• LFE Output: The azur 351R is equipped with a single LFE output to connect a powered sub.
• Headphone Output: The receiver features a 1/4" stereo headphone jack on its front-panel for connecting a pair of optional headphones. Plugging in a set of headphones will automatically mute the main speakers and pre-amp outputs, while selecting a 2-channel stereo down-mix soundfield. Headphones with an impedance of between 32-600 ohms are recommended.

FM Tuner w/ RDS: The Cambridge Audio A/V receiver features a built-in FM tuner with RDS. RDS is a method for the transmission of additional information from local radio stations. RDS will only work if the local broadcasting stations have RDS transmission and the signal is strong enough. There is no AM tuner.

Video Features

HDMI (ver.1.4): The 351R boasts four HDMI (ver.1.4) inputs and a single HDMI (ver.1.4) monitor output which fully support 3D, Deep color, and Audio Return from newer flat-panel TVs. HDMI (High-Definition Multi-Media Interface) is an all digital connection that can carry both audio/video in one cable and supports various types of High Definition video content and high resolution audio.

3D Pass-Through: With the advent of 3D media, it is important to own a receiver that recognizes 3D video signals. The 351R is able to pass through 3D signals from your Blu-ray player, ensuring that the 3D effect doesn't get lost in translation. It also recognizes signals from 3D television broadcasts. By connecting a 3D-compliant Blu-ray disc player and 3D-compliant TV to the 351R , you will have a 3D home theater where you can enjoy high-definition sound and video on a level you've never experienced before.

Deep Color Support: The 351R also supports Deep Color content, which can display a larger color range than standard-definition schemes. The result is a more lifelike, vibrant picture.

Audio Return Channel: This feature allows audio to be sent from your compatible HDTV to your receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television.

Lipsync Adjustment: This feature compensates for the timing shift between the audio and video of the receiver. If needed, the audio signal can be manually delayed to match the video signal; adjust from 0-500ms (in 10ms steps).

Convenience Features

Slim, Aesthetic Design: The Cambridge Audio azur 351R features a slim designed chassis which measures only 16.9375" (w) x 4.1875" (h) x 14.6875" (d); so it easily fits on a shelf or inside a cabinet.

On-Screen Display (via HDMI): The AV receiver's on-screen menu provides quick information about your system's settings. You can easily make settings for your home theater system while viewing menus on the TV screen. Simple settings are enabled with the setting menus displayed on the TV screen. These menu displays can only be output to your TV via HDMI. The unit's front-panel LCD also displays the receiver's menu adjustments, as well as input source.

X-Tract Cooling System: The Cambridge Audio azur 351R employs a unique cooling system called X-Tract. A perfectly balanced combination of forced cooling and natural convection effectively draws heat away from the substantial transformer and output stages and means the 351R can operate extremely quietly, at a low temperature and enables a more compact enclosure than would normally be possible.

Backup Memory: The 351R has a function that preserves the preset memory and other settings. In the event of a power failure, or if the power cord of the unit is disconnected from the mains outlet, the back-up memory will preserve the preset memory for approximately one week. If the power supply is interrupted for 7 days or longer, the memory settings will be erased.

Remote Control

IR Remote Control: The azur 351R comes with an IR wireless remote control that can operate this receiver only.

Remote Connections: The Cambridge Audio azur 351R is fitted with the following custom remote connections.

• IR Input: This 3.5mm input is used to control the 351R from an external key-pad (sold separately).
• RS232C Port: The RS-232C port is to be used in conjunction with an external controller to control the operation of the unit by using an external device. The RS-232C port may also be used in the future to update the operating software of the unit so that it will be able to support new digital audio formats.
