Note: In addition to the delays as set above Dolby Pro Logic II/IIx playback

also requires an extra 15 milliseconds delay to the surround channels only.

This extra delay is part of the Dolby Pro Logic II specication and ensures that

sound from the surrounds arrives just after sound from the front reducing the

audibility of sound leakage from the front to the surround speakers. Because

the relationship between the Dolby Digital and Dolby Pro Logic IIx two delays

is xed (15mS extra to the surround channels), it is only necessary to set the

delay by measuring the distances as we have described. The 551R V2 will

automatically provide the appropriate extra delay whenever you switch to a

Dolby Pro Logic Mode.

Level calibration

The 551R V2 allows level calibration to match the acoustic level between

different types/sizes or even manufacturers of speaker that may be being

used for each channel. This is achieved by adjusting the relative level of

each speaker. This can be done manually through the 'Level Calibration'

menu in the OSD or automatically, see the following Auto setup section of

this manual.

The basic process for manual adjustment is to listen to or measure with a

Sound Pressure Level (SPL) meter (more accurate and recommended but

not essential) the level of sound produced by each speaker and set relative

levels for each speaker so that they all sound the same loudness at the

normal listening position. The 551R V2 incorporates a Test Signal Generator

(broad-band white noise) to facilitate this.

Press the OSD button on the remote control then select the 'Level Calibration'

menu. Now turn on the test signal by highlighting this item and pressing the

◄ or ► arrows:

You can now move up and down the channels using the ▲ and ▼ buttons on

the remote. Each time a new channel is selected the test signal will be heard

to move to that channel. Compare the loudness of all channels as heard at

the listening position.

A "rushing" or "hissy" sound should be heard.

Now adjust the channels so they all sound the same (in terms of loudness

only, channels of different frequency responses can sound different in terms

of the "tone" of the sound i.e. more or less hissy).

Pick the channel that sounds most different and select it to listen to the

test signal. Now adjust the relative level in dB (using Arrow left/right on

the remote) and continue comparing it to other channels until it is of equal

loudness. The level can be adjusted up to + or - 10dB in 1dB steps. Repeat

the process with the next most different channel. Once all channels sound

the same in terms of loudness, press the OSD button again to save the

settings and exit the menu.

Auto speaker setup for Distance/Level

Important note: Please remember that test signals generated from Auto

setup are loud.

The 551R V2 includes our simple automatic speaker setup system called

'CAMCAS' (Cambridge Audio Mic Controlled Auto Setup). The system performs

two sets of tests rstly checking which speakers are connected and whether

they are wired correctly and in phase then second automatically measuring

and adjusting the speaker delay timings (i.e. distance setting ) and levels.

Before activating this feature the 'Decode Mode' (i.e. type of speaker

package e.g. 5.1, 7.1) of the 551R V2 and Large/Small/None status of each

speaker must be set correctly as per section 1. This is important as the unit

will only look for and check the speakers you have told it you have.

To perform Auto Distance/Level setup rst connect the supplied microphone

to the front Left front panel audio input on the front panel and place it at your

normal listening position in the room.

Press the OSD button on the remote control to access the OSD and select the

option 'Auto Setup'. This will access the 'Auto Setup Menu' as below.

Once activated the OSD will display the message below and the word

'AUTOSETUP' will also be displayed on the front panel of the 551R V2 to

conrm.

The unit is now checking which

speakers are connected and their

Please wait....

A series of test signals will now be output from all of the connected speaker

terminals of the 551R V2 (including the Subwoofer output).
