[. . . ] Setting the Subwoofer to ‘No’ will automatically result in the Front Left and Right being set to ‘Large’. Set the distances in the OSD Speaker Distance menu to the nearest value in metres (1 foot = 0. 3 metres). The speed of sound is approx 340 metres per second, the 551R thus introduces approx 3mS of delay per metre 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): Press the OSD button to exit the menu. 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 ‘Yes’. Also, setting the Front Left and Right as ‘Small’ will always set the other speakers as ‘Small’ (and the Sub to ‘Yes’). This is because LFE/ bass information should not be redirected to the surround channels. Speaker Distance Menu Unit Front L Front R Centre Surr. RB : : : : : : : : Return : [OSD] Meters 2. 9 2. 9 2. 9 2. 0 2. 0 2. 0 2. 0 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). 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 551R will automatically provide the appropriate extra delay whenever you switch to a Pro Logic Mode. 15 Level calibration The 551R 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 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 incorporates a Test Signal Generator (broadband 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 Left or Right arrows: Level Calibration Menu Speaker Setup Menu Test Signal Front L Front R Surround L Surround R Centre Subwoofer Surr.

Press the OSD button on the remote control to access the OSD and then select the Speaker Setup Menu. This will access the 'Auto Setup Menu' as below. Return : [OSD] You can now move up and down the channels using Volume Up/Down 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. Follow the on-screen instructions and press 'Enter' on the remote control when ready to start the Auto Setup function. Auto Setup Menu Plug the microphone into the left channel of Video 3 on the front panel and place the microphone at normal listening position and height Continue : [ENTER] Once activated the OSD will display the message below and the word 'AUTOSETUP' will also be displayed on the front panel of the 551R to confirm. Auto Setup Menu The unit is now checking connected and their phase which speakers are Pick the channel that sounds most different and select it to listen to the test signal. [. . . ] 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. 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. Left Surround Rear (150°) Right Surround Rear (150°) Repeat this procedure with the Mute, Sub On/Off, Stereo Mono and Tuner AM/FM buttons to send On/Off commands. [. . . ]
