Cambridge Audio 551R Manuale Utente

Front Left and Right speakers

For stereo and multi-channel sound.

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.

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.

Subwoofer

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.

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 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 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 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 Configuration’ menu

by using volume up and down on the remote then go to it by pressing Enter:

551R setup

The setup of the 551R 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 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.
