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. The graphic symbol of an exclamation point within an equilateral triangle warns a user of the device that it is necessary to refer to the instruction manual and its warnings for proper operation of the unit. [. . . ] 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. 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. 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. This function can be altered only when the AV 713 is in DOLBY PRO-LOGIC or HALL Mode. In normal (FM MUTE ON) operation, during the tuning process the tuner will mute when there is little or no signal present, giving silence until a station with a reasonably strong signal is found. Pressing FM MUTE/MODE will switch off the mute function so that very weak stations can be located. When a stereo FM signal is being received, your AV 713 will automatically switch to Stereo FM operation, which will be shown by STEREO indicator in the Display Panel. [. . . ] Using a separate center channel speaker will allow the dialogue to cut through even the biggest sound effects and musical scores. Having the sound spread across three front speakers also stabilises the stereo image, making the usable listening area much bigger. If you are using the AV 713 with only two front speakers, setting the CENTER mode to PHANTOM will place the center information on both the left and right speakers. Ideally it should be the same type as the left and right speakers, although there are now many new speakers, such as the NAD 808CC, which are specifically designed as center channel add-ons for existing stereo systems.
