Plug Fitting Instructions (UK Only) The cord supplied with this appliance is factory fitted with a UK mains plug fitted with a 13 amp fuse inside. If it is necessary to change the fuse, it is important that a 13 amp one is used. If the plug needs to be changed because it is not suitable for your socket, or becomes damaged, it should be cut off and an appropriate plug fitted following the wiring instructions below. The plug must then be disposed of safely, as insertion into a mains socket is likely to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires should be fitted as shown in this diagram. The colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug. Connect them as follows:
The wire which is coloured BLUE must be connected to the terminal which is marked with the letter 'N' or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal which is marked with the letter 'L' or coloured RED.
The wire which is coloured GREEN/YELLOW must be connected to the terminal which is marked with the letter 'E' or coloured GREEN.
If your model does not have an earth wire, then disregard this instruction.
If a standard 13 amp (BS 1363) plug is used, a 13 amp fuse must be fitted, or if any other type of plug is used a 13 amp fuse must be fitted, either in the plug or adaptor, or on the distribution board.
Limited warranty
Ventilation IMPORTANT The unit will become hot when in use. Do not stack multiple units on top of each other. Do not place in an enclosed area such as a bookcase or in a cabinet without sufficient ventilation.
Ensure that small objects do not fall through any ventilation grille. If this happens, switch off immediately, disconnect from the mains supply and contact your dealer for advice.
Positioning Choose the installation location carefully. Avoid placing it in direct sunlight or close to a source of heat. No naked flame sources, such as lighted candles, should be placed on the unit. Also avoid locations subject to vibration and excessive dust, cold or moisture. The unit can be used in a moderate climate.
This unit must be installed on a sturdy, level surface. Do not place in a sealed area such as a bookcase or in a cabinet. Any space open at the back (such as a dedicated equipment rack) is fine, however. Do not place the unit on an unstable surface or shelf. The unit may fall, causing serious injury to a child or adult as well as serious damage to the product. Do not place other equipment on top of the unit.
Due to stray magnetic fields, turntables or CRT TVs should not be located nearby due to possible interference.
Electronic audio components have a running in period of around a week (if used several hours per day). This will allow the new components to settle down and the sonic properties will improve over this time.
Power sources The unit should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power-supply to your home, consult your product dealer or local power company.
This unit can be left in Standby mode when not in use and will draw <0.5W in this state. To turn the unit off, switch off at the rear panel. If you do not intend to use this unit for a long period of time, unplug it from the mains socket.
Overloading Do not overload wall outlets or extension cords as this can result in a risk of fire or electric shock. Overloaded AC outlets, extension cords, frayed power cords, damaged or cracked wire insulation and broken plugs are dangerous. They may result in a shock or fire hazard.
Be sure to insert each power cord securely. To prevent hum and noise, do not bundle the interconnect leads with the power cord or speaker leads.
Cleaning To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any cleaning fluids containing alcohol, ammonia or abrasives. Do not spray an aerosol at or near the unit.
Battery disposal Batteries may contain substances harmful to the environment. Please dispose of any discharged batteries with due consideration and in accordance with local environmental/electronic recycling guidelines.
Loudspeakers Before making any connections to loudspeakers, make sure all power is turned off and only use suitable interconnects.
Servicing These units are not user serviceable. Never attempt to repair, disassemble or reconstruct the unit if there seems to be a problem. A serious electric shock could result if this precautionary measure is ignored. In the event of a problem or failure, please contact your dealer.
IMPORTANT If the unit is run at a very high level, a sensor will detect a temperature rise and show "PROTECTION OVERLOAD" on the display. The unit will then go into Standby mode. It cannot be switched on again until the temperature has fallen to a more normal level.

To avoid damaging the speakers with a sudden high-level signal, be sure to switch the power off before connecting the speakers. Check the impedance of your speakers. Speakers with an impedance of 8 ohms (each) are recommended.
The coloured speaker terminals are positive (+) and the black speaker terminals are negative (-). Make sure correct polarity is maintained at each speaker connector or the sound can become weak and "phasey" with little bass.
Prepare the speaker cords for connection by stripping off approximately 10mm (3/8") or less (no more than 10mm, as this could cause a short- circuit) of the outer insulation. Twist the wire tightly together so there are no loose ends. Unscrew the speaker terminal knob, insert the speaker cable, tighten the knob and secure the cable.
Note: All connections are made via loudspeaker cable, except if using an active subwoofer which would be connected via a standard RCA phono cable.
Banana Plugs (4mm standard) connected to the speaker cable are recommended for direct insertion into the speaker terminals.
Please refer to the 'Speaker Configuration' section of this manual for more information on 5.1 and 7.1 speaker setups.

These connections are pure analogue for best sound quality and no DSP processing or Bass and Treble adjustment by the 551R V2 is possible.
DVD-A or SACD players can be connected to the 551R V2 via its 5.1/7.1 Direct inputs allowing multi-channel music playback from these sources.
DVD-A and SACD both support 5.1 output. The 551R V2's direct inputs also allow optional connection of Surround Back or Surround Left and Surround Right signals for compatibility with future 7.1 sources or external decoders.
To select the Direct Input press the 7.1 Direct button on the front panel or remote.
It can be desirable to connect DVD-A/SACD players to the 551R V2 by two methods at the same time.

Video output connection (HDMI)
The output connection to the TV is through HDMI only. See later section.
Two outputs are fitted that can be used individually or at the same time (for a TV and projector perhaps).
Note: Both outputs always show the same video and are also 4K compatible. See the HDMI/Component Assign menu below on how to select the active HDMI output in the On Screen Display menus.

If it is desired to connect external power amplifiers, use Phono/RCA leads connected to the 7.1 Preamp Outputs on the rear panel.
For 5.1/7.1 use set the 'Preamp Out' setting in the 'Output Setup' OSD menu to 'Pre Out' rather than 'Normal'. This mutes all the internal power amplifiers as they are not being used.

Alternatively the 551R V2 features an External 2-Channel mode. This allows the 551R V2 to reproduce all the surround channels of suitable source material (Centre, Surrounds and Sub) whilst the Left and Right Front speakers are driven by an external power amplifier or other amplifier capable of supporting fixed level inputs (e.g. Cambridge Audio's own 7/8 series amplifiers).

HDMI 1 also supports an HDMI 1.4 Audio Return Channel from TVs that also support this feature.
This allows audio from the TVs own in built tuner to be received by the 551R V2. See later TV-ARC section for details.
ARC supported if TV also supports.

Front input connections
The front panel Video 3/MP3 input is for temporary connections to audio player etc. Remove the cap to access the Video 3 inputs and connect to a audio player's outputs using stereo phono cables (RCA-RCA). Alternatively, use the 3.5mm mini-jack MP3 socket for the headphone/line outputs of portable MP3 players.

MP3 Player
When pressing Video 3/MP3, the 551R V2 automatically selects the MP3 socket if there is a device plugged into it.
Note: The Auto Setup input is used for the supplied auto setup microphone. Refer to the 'Auto setup' section of this manual for more information.
Aerial connections
FM aerial Connect an aerial to the FM 75 ohm socket (a simple wire aerial is supplied only for temporary use). Extend the lead and move the aerial around until you get the best reception. For continued use, we strongly recommended using a 75ohm outdoor FM aerial.
AM loop aerial Connect each end of the single length antenna to the antenna terminals. Place the antenna as far from the main system as possible to prevent unwanted noise and to obtain optimum reception. If the AM loop aerial provided does not receive sufficient reception, it may be necessary to use an outdoor AM aerial.

551R V2 setup
The setup of the 551R V2 is a reasonably simple 4 stage process. The speaker setup process (stage 2.) can either be performed manually or via the CAMCAS (Cambridge Audio Microphone Controlled Auto Setup) procedure.
The procedure is as follows:
1. Speaker configuration.
2. Speaker setup (Speaker delay and Level calibration)
3. Assigning HDMI and Analogue video inputs
4. Source setup
1. Speaker configuration First tell the unit what kind of speaker package you have. The options are 5.1 or 7.1 as shown below. The 551R V2 can support up to a 7.1 speaker setup which means 7 speakers (Front Left, Front Right, Centre, Surround Left, Surround Right, Surround Back Left, Back Right) plus a mains powered Subwoofer (the .1).
Refer to the diagrams below for typical examples of 5.1 and 7.1 loudspeaker setups. Always adjust the speaker and listening positions until you are happy with the sound. Please refer to your loudspeaker and subwoofer manuals for more detailed positioning information.

1 Front Left and Right speakers For stereo and multi-channel sound.
2 Centre speaker For dialogue and centre sounds. Ideally position at a similar height to the front left and right speakers (above or below the TV/monitor). Using a centre speaker from the same manufacturer/range as used for the front left and right speakers is advisable. This "timbre matching" allows surround effects to flow more naturally from left to right without obvious transitions between the speakers.
3 Surround Left and Right speakers For ambient and multi-channel sound. Floorstanding speakers should be angled towards the listening position. Bookshelf/standmount speakers should be wall mounted or used with dedicated speaker stands, positioned at or above ear height.

For improving the bass in your system, as well as reproducing dedicated LFE (Low Frequency Effects) cinema effects when playing Dolby Digital or DTS encoded discs. Your subwoofer can often be placed almost anywhere in the room as bass is less directional, but experimentation with positioning is recommended.
5 Surround Back Left and Right speakers Individual back speakers in place of a single surround back. Used with the 7.1 processing types. Remember to experiment with the positions until you are happy with the sound.
In each case the 5.1/7.1 in fact relates to the maximum number of speakers that can be used, as the Centre, Sub and Surround speakers can all be deleted if required (although of course performance is reduced). For example, if you choose not to use a Centre Channel speaker you can set this to 'None' in the settings as shown later and the 551R V2 will automatically redirect the centre channel audio information into the Left and Right Front channels, creating what is known as a 'Phantom Centre'.
Similarly, you might decide not to use a subwoofer if your main Left and Right speakers are capable of reproducing enough bass for a satisfying music/ movie experience. The 551R V2 will then automatically re-direct the bass from the Subwoofer/Low Frequency Effect channel to the Left and Right Front Speakers.
Note: This setup is very important as the 551R V2 will also automatically use this information to select appropriate Dolby and DTS decoding modes dependant not only on the source material but also the speaker package it knows you have.
To tell the unit the type of package you have, turn on the On-Screen Display via the remote button as shown. Highlight the 'Speaker Config.' menu by using the and button on the remote then go to it by pressing the Enter button:
