User manual NAD 118

[. . . ] 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 soon as any one of the buttons or controls on the front panel are used (apart from High Gain) the volume setting and all settings for any of the DSP modes will default to the actual position of the controls of the front panel. Alternatively, instead of touching any of the controls on the front panel, press the Front Panel button on the remote control (2 on remote control drawing) to go back to the front panel default setting. The NAD Model 118 has several special Digital Signal Processing (DSP) functions which will allow you to change and enhance the overall sound quality. This button scrolls through the various DSP functions: With this DSP function you can change the tonal balance of the music. BASS: Rotate control 17 on the front panel clockwise or the press the BASS + button on the remote control (section 11 on remote control drawing) to increase the relative level of low-frequencies in the sound. Rotate control 17 on the front panel counter clockwise or the press the BASS - button on the remote control (section 11 on remote control drawing) to decrease the relative level of low-frequencies in the sound. The LEDs in the display area (26) indicate which function is engaged and which of the three controls (17, 18 or 19) can be used to change the settings of that particular DSP function. The desired DSP function can be accessed direct with the remote control by pressing the desired function button (from section 3 on remote control drawing). The LEDs in the display area (26) indicate which function is engaged and which buttons (section 11 on remote control drawing) can be used to change the settings of that function. Rotate control 18 on the front panel counter clockwise or the press the MID - button on the remote control (section 11 on remote control drawing) to decrease the relative level of mid-frequencies in the sound. TREBLE: Rotate control 19 on the front panel clockwise or the press the TREBLE + button on the remote control (section 11 on remote control drawing) to increase the relative level of high-frequencies in the sound. Rotate control 19 on the front panel counter clockwise or the press the TREBLE - button on the remote control (section 11 on remote control drawing) to decrease the relative level of high-frequencies in the sound. Rotate the control (17) fully counter clockwise, or if you are using the remote control, press BASS Down (section 11 on remote control drawing) until the LED bar in the display area (26) indicates minimum level, as in the drawing below. This DSP function works and operates in the same manner to the DSP function described above but BASS has been replaced by a non-adjustable Infrasonic filter. The infrasonic filter removes very low frequencies which can sometimes have a disturbing effect on the overall music quality. These low frequencies, which often do not have any relation to the music itself, can emanate from a turntable or recordings made from it and sometimes even CD players. If these extremely low frequencies aren't filtered out they can put a significant strain on power amplifiers and loudloudspeakers. It is relatively easy to check if any of your program material contains unwanted infrasonic sounds: 1. Remove the grilles from the loudloudspeakers (check the owner's manual of the loudloudspeakers first for the correct procedure; note that not all loudloudspeakers have removable grills). Whilst playing music at a normal, realistic listening level observe the loudspeaker cones. Without changing volume, switch DSP in (15; button IN/OUT on front panel, 10 on remote control drawing). If there is a significant reduction in loudspeaker cone movement then it is likely that that particular piece of music does contain unwanted low-frequency energy, in which case it is recommended you leave Infrasonic switched on. [. . . ] NOTE: When changing to a different input after having called up a Memory Bank the pre-amp will also engage the Memory Bank for the newly selected input. When the desired configuration has been selected, press any of the buttons on the front panel, apart from the High Gain (21) and the input selector buttons (4 to 12). Clear EEPROM; return to factory default settings On: Dithering for dig. Record output always switched on regardless of Process to tape button position Unassigned Unassigned Amplification factor; for the Model 118 the input sensitivity (and therefore the amplification factor) for the analogue sources can be changed to prevent overloading of the ADC (signal too loud) or not exploiting the ADC to its full potential (signal too low).
