[. . . ] 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. If the Front Left and Right are set as `Small' the Sub must be Set to `On'. Also, setting the Front Left and Right as `Small' will always set the other speakers as `Small' (and the Sub to `On'). 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). 3 3 4 = Surround Back speaker (when used) 5 = Surround Back Left & Right (when used) 5 4 5 Note: No delay setting for the subwoofer is necessary. Set the distances in the OSD Speaker Delay menu to the nearest value in metres (1 foot = 0. 3 metres). The speed of sound is approx 340 metres per second, the 640R thus introduces approx 3mS of delay per metre of distance set. Go to the `Speaker Delay Menu' 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): Speaker Delay Menu Front L/R Centre Surr. LB/RB : : : : 7. 14m 5. 44m 4. 08m 3. 06m [Unit :Meters] Return To Menu : [OSD] Press the OSD button to exit the menu. 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 Prologic II specification 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 ProLogic IIx two delays is fixed (15mS extra to the surround channels), it is only necessary to set the delay by measuring the distances as we have described. The 640R will automatically provide the appropriate extra delay whenever you switch to a Pro Logic Mode. 15 3. Level calibration The 640R 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 through the `Level Calibration' menu in the OSD. [. . . ] 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 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. [. . . ]
