User manual NAD 713

[. . . ] If an indoor antenna is used (either built into the set or installed separately), never allow any part of the antenna to touch the metal parts of other electrical appliances such as a lamp, TV set etc. Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. The graphic symbol of a lightning flash with an arrow point within a triangle signifies that there is dangerous voltage within the unit and it poses a hazard to anyone removing the cover to gain access to the interior of the unit. Only qualified service personnel should make any such attempt. [. . . ] The selected mode is displayed in the main area of the Display Panel for 3 seconds and is continuously shown in Surround Mode area of the Display Panel. As an additional convenience feature, your AV 713 memorizes which surround mode you have used with the given input selection. When you next select that input, your AV 713 will automatically choose the same Surround mode again. If you normally use Dolby Pro-Logic mode on the Video 1 and Video 2 inputs, Hall Mode on FM, and By-Pass (Stereo) on the others, pressing the Input Selector will automatically default to the right Surround mode without having to separately press the Surround Mode button. If the Tone Controls are not normally used and left in the 12 o'clock position, then it is advisable to switch out the Tone Control section altogether by using this switch. Pressing the CENTER button pages through the three options: NORMAL, PHANTOM and WIDEBAND. NORMAL mode is used when the center speaker is smaller than the front left and right speakers. This mode produces a true center image with the very low frequencies (below 70Hz) filtered out. WIDEBAND mode is used when the center speaker is the same type as the front left and right speakers. This mode produces a true center image with a full frequency range and no low frequency filtering. PHANTOM mode is used when there is no center speaker. The AV 713 places the center information equally on the left and right front speakers so producing a `Phantom' central sound image. The selected Center Mode is displayed for 3 seconds in the main area of the Display Panel. It is stored in the AV 713's memory and will be automatically recalled each time the unit is switched on. This function can be altered only when the AV 713 is in DOLBY PRO-LOGIC Mode. Video 1 or 2 is shown in the Display Panel when these are selected If the CD is the active input when TAPE MONITOR is selected, then the CD signal will continue to be sent to the recording outputs of TAPE 1, TAPE 2 and VIDEO 2, whilst the Tape 2 signal will be heard on the loudspeakers and headphones. This is also automatically selected when an FM Preset is selected. This is also automatically selected when an AM Preset is selected. Selects the amount of delay applied to the surround speakers when the AV 713 is used in DOLBY PROLOGIC or HALL modes. Pressing the DELAY button steps the Delay times in 5mS steps from 5mS to 30mS for Hall mode and from 15mS to 30mS for Dolby Pro-Logic mode. Separate delay times can be stored for DOLBY PROLOGIC and HALL modes and are held in the AV 713's memory. They are automatically recalled each time the DOLBY PRO-LOGIC or HALL mode is selected. [. . . ] Unshielded speakers used too close to a TV or monitor may cause colour distortions of the TV picture. (It is not normally possible to modify an unshielded speaker to work very close to a TV or monitor). The AV 713 can be used at the heart of a broad range of surround sound systems. Many film soundtracks rely heavily on very low frequency sound effects which are difficult for normal hifi speakers to reproduce. [. . . ]
