[. . . ] In each case the 5. 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 351R 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 351R will then automatically re-direct the bass from the Subwoofer/Low Frequency Effect channel to the Left and Right Front Speakers. 12 azur 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. 351R ENGLISH Level calibration The 351R 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 351R incorporates a Test Signal Generator (broadband white noise) to facilitate this. button on the remote control to turn on the OSD then select the Press the 'Speaker Level' menu. Now turn on the test signal by highlighting this item and pressing the Left or Right arrows: azur 351R Audio In.

R Center Subwoofer Off <> 0dB <> 0dB <> 0dB <> 0dB <> 0dB <> 0dB <> Speaker Delay Because the speakers in a surround sound system are usually different distances from the listener the 351R 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. 1 = Front Left speaker 1 3 2 2 = Front Right speaker 3 = Centre speaker 4 = Surround Left speaker 5 = Surround Right speaker 6 = ubwoofer (can be placed S almost anywhere) 5 6 4 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: No delay setting for the subwoofer is necessary. Set the distances in the OSD Speaker Distance menu to the nearest value in metres or feet (1 foot = 0. 3 metres). The speed of sound is approx 340 metres per second, the 351R thus introduces approx 3mS of delay per meter 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): azur 351R Audio In.

Dimension Adjusts the soundfield to be gradually shifted from the front of the room to the back to suit taste, speaker positioning and size of room. Setting 0 has the image furthest forward, 6 furthest back. All three adjustments are a matter of personal preference, experiment for the settings that you prefer when you are using Dolby Pro Logic II decoding. 4. [. . . ]
