ENGLISH

For playback the 551R expects you to have an actual physical speaker setup

approximately conforming to one of the layouts as shown below.

For 5.1 setups the situation is simple, the 551R automatically performs any

DTS Speaker Remapping required, mapping any of the 7 incoming

possibilities to this configuration.
For 7.1 there are two alternative speaker setup you might have. These

corresponds to configuration 1 and configuration 5 as above.
Here you need to tell the 551R which configuration best matches your

speaker setup by selecting the DTS-HD speaker menu and selecting the 1 or

5 option.

The 551R can then perform any speaker re-mapping required automatically,

and maps any of the incoming 7 possibilities to whichever one of the two 7.1

possibilities you have.
Note: This feature by its nature only works for 7.1 DTS HD Master Audio or

DTS HD High Resolution Audio bitstreams.
Also note that where the incoming speaker configuration and your physical

speaker configuration actually match the 551R performs no mapping as

you’d expect.

An IR Emitter Input is provided that allows

modulated IR remote control commands to be

received electrically by the unit. An RS232 port is

also featured which allows the 551R to be controlled

by C.I. systems.

In addition the unit features 'direct' IR/Control codes as well as toggle codes

for some of their features to simplify programming custom installation

systems. Special direct On/Off and Mute commands can be accessed on the

supplied remote control for teaching into C.I. systems as follows:
1.Press and hold the Standby/On button on the remote control. The remote

first generates it's standby (toggle) command. Keep the button held down,

after 12 seconds an AV receiver “On” command will be generated. If the

button is kept held down for a further 12 seconds, an AV receiver “Off”

command is generated.

Repeat this procedure with the Mute, Sub On/Off, Stereo Mono and Tuner

AM/FM buttons to send On/Off commands. The Tuner AM/FM button also

provides unique FM and AM commands to allow switching to a specific band.
A full code table and RS232 protocol for this product is available on the

Cambridge Audio website at www.cambridge-audio.com.

The 551R 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.
If it is desired to reset all settings to their factory defaults (or in the unlikely

event that the unit locks up due to an electrical discharge etc), with the unit

on and out of Standby mode press and hold the DVD and Analogue Stereo

Direct buttons on the front panel for three seconds.
“RESET” will appear briefly on the front panel display before returning to

Standby mode.
