[. . . ] The 640R will then automatically re-direct the bass from the Subwoofer/Low Frequency Effect channel to the Left and Right Front Speakers. 4 6. 1 3 5 3 Note: This setup is very important as the 640R 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. 1 1 2 First tell the unit the type of package you have. Highlight the `Speaker Configuration' menu by using volume up and down on the remote then go to it by pressing Enter: azur 640R V1. 0 Speaker Configuration Speaker Delay Level Calibration Input/Output Setup Input Name Assign HDMI Setup/Assign Rec. 2 Output Select OSD Setup Tone/Sub/LFE Config.

Speaker delay Set the package as 5. 1, 6. 1 or 7. 1 by highlighting the Decode Mode item and using the Left and Right arrows to scroll through the options: Speaker Config Menu Decode Mode :7. 1 Front L/R :Large Centre :None Surr. LB/RB :None Subwoofer :Off [FL/R Must Set Large When Sub. Set Off] Return To Menu : [OSD] 640R ENGLISH Because the speakers in a surround sound system are usually different distances from the listener the 640R 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 surroundsound effect. Front Left and Right or Surround Left and Right) are subject to the same delay and so must be situated equidistant from the listener. To set the delay times simply measure the distances from the listening position to each speaker as shown in the following diagram: 1 2 1 1 = Front Left & Right speakers 2 = Centre speaker 3 = Surround Left & Right speakers Now move down and by highlighting each speaker in turn and using the Left and Right arrows 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 reflect the actual physical size of the speaker. Large = Speakers with an extended low frequency response of approximately 20-40Hz to 16-20kHz (floorstanders 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 640R 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 On or Off. If no sub is being used make sure this setting is set to Off to allow the 640R to re-direct the bass information in this channel to other speakers. Note: The 640R will force some speakers to certain settings in some of 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 `On'. Setting the Subwoofer to `Off' 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. [. . . ] A full code table and RS232 protocol for this product is available on the a Cambridge Audio website at www. cambridge-audio. com. Sound cuts off when listening to music or there is no sound even though power is ON Speaker impedance is less than prescribed for the 640R. The unit is not adequately ventilated and may be overheating. Low bass or "phasey" response Speaker polarity (+/-) of one or more speakers is reversed. An unusual hissing noise is heard when listening to a radio broadcast in stereo, but not heard when listening in mono A slight noise may be heard because the method used for modulation of FM stereo broadcasts is different than that used for mono broadcasts. Aerial quality also effects the level of hiss heard. Noise is excessive in both stereo and monaural radio broadcasts Poor location and/or direction of the antenna. Transmitting station is too far away. No sound from the rear speakers Source being played is not recorded in surround sound. Reset/Back-up memory The 640R has a function that preserves the preset memory and other settings. [. . . ]
