ENGLISH

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 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 Cong.' menu by

using the ▲ and ▼ button on the remote then go to it by pressing the Enter

button:

Set the Decode mode as 5.1 or 7.1 by highlighting the Decode Mode menu

item and using the ◄ and ► buttons to scroll through the options:

Now move down by highlighting each speaker in turn and using the ◄ and ►

buttons, then select from 'Large', 'Small' or 'None' for each speaker. 'Large' or

'Small' are used to describe each speaker in terms of bass response, they do

not necessarily reect the actual physical size of the speaker.

Large – Speakers with an extended low frequency response of approximately

20-40Hz to 16-20kHz (oorstanders or high quality larger stand-mounted

speakers).

Small – Speakers with a less extended low frequency response of

approximately 80-100Hz to 16-20kHz (small stand-mounted, bookshelf or

satellite speakers).

Setting each speaker allows the 551R V2 to perform what is called Bass

Management and to direct low frequency bass from music and the Low

Frequency Effects channel of surround sound material to those speakers

best able to reproduce it. If you do not wish to use any of the speakers set

its setting to 'None'.

The Subwoofer output can also be set to Yes or No. If no sub is being used

make sure this setting is set to No to allow the 551R V2 to re-direct the bass

information in this channel to other speakers.

Note: The 551R V2 will force some speakers to certain settings in the

following circumstances!

The Front Left and Right speakers may be 'Large' or 'Small' but never 'None'

as they are always required for any type of music/movie reproduction.

Bass must always be reproduced by either the Front Left and Right or

Subwoofer channel (or both). Setting the Front Left and Right to 'Small'

will result in the Subwoofer automatically being set to 'Yes'. Setting the

Subwoofer to 'No' will automatically result in the Front Left and Right being

set to 'Large'.

If the Front Left and Right cannot reproduce low frequency bass a Subwoofer

must be used, i.e. If the Front Left and Right are set as 'Small' the Sub must

be Set to 'Yes'.

Also, setting the Front Left and Right as 'Small' will always set the other

speakers as 'Small' (and the Sub to 'Yes'). This is because LFE/ bass

information should not be redirected to the surround channels.

To store the setting simply come back out of the OSD (pressing the OSD

button always moves back one menu item, and then exits and stores from

the main menu screen).

2. Speaker setup

The following two sections can be performed by Cambridge Audio CAMCAS

procedure so you can if you wish jump straight to that section. However, it is

recommended that you do read these sections to understand the reasons for

these settings and their implications.

Speaker delay

Because the speakers in a surround sound system are usually different

distances from the listener the 551R V2 incorporates the ability to apply a

variable digital delay to each of the channels so that the sound from each

arrives at the same time at the listening position for best surround-sound

effect.

To set the delay times automatically, refer to the Auto setup section of this

manual.

To set the delay times manually, simply measure the distances from the

listening position to each speaker as shown in the following diagram:

1 = Front Left speaker

2 = Front Right speaker

3 = Centre speaker

4 = Surround Left speaker

5 = Surround Right speaker

6 = Surround Back Left

(when used)

7 = Surround Back Right

(when used)

8 = Subwoofer (can be placed

almost anywhere)

Note: No delay setting for the subwoofer is necessary.

Set the distances in the OSD Speaker Distance menu to the nearest value

in metres (1 foot = 0.3 metres). The speed of sound is approx. 340 metres

per second, the 551R V2 thus introduces approx. 3mS of delay per metre

of distance set.

Go to the 'Speaker Distance' and highlight each speaker in turn. Set the

distance to the nearest value to that which you measured by using the Left

and Right arrows (the values do not need to be exact):

Press the OSD button to exit the menu.
