[. . . ] The terminals are separated by 3/4 inch (19mm), so they will accept dual-banana plugs. Before using banana plugs, the red and black inserts have to be removed with the aid of a small screwdriver. Separate the two conductors of the cord, and strip off a half-inch (1 cm) of insulation from each. Unscrew the red or black bushing, insert the bare wire through the hole in the metal shaft, and tighten the plastic bushing until it grasps the wire securely. [. . . ] Rotation of the Treble control to the right (clockwise) increases the level of high-frequency sounds, and rotation counterclockwise decreases their level. adjust the Treble control to achieve the tonal balance that sounds most natural to you. Boosting the Treble increases the brilliance and clarity of details in the sound, but also makes any noise more prominent. Turning down the Treble makes the sound mellower while suppressing hiss and record surface noise; but too much Treble roll-off will make the sound dull. the Treble control has no effect if the TONE DEFEAT button is engaged. NOTE: At high volume settings (with the volume control over the 12 o'clock position) both the Bass and Treble controls do not have any effect anymore. NOTE: When the amplifier is switched off with a source (such as a CD) still playing there will still be sound for as much as several seconds, depending on the volume level, before it eventually dies out. Although completely harmless, it can be avoided switching off the source first or by turning down the volume first. CAUTION: In the off position the unit is still connected to the mains. Disconnect the power cable when the unit is not to be used for a long time. The POWER indicator glows green when the amplifier is switched on and ready for use. The amplifier incorporates protection circuitry against conditions such as overheating, short circuits, and DC off-set. Under normal conditions, this indicator will not light up and the unit will operate normally. If however one of the decribed conditions occur, the indicator will light up red and the unit will stop working. tURN DOWN the volume all the way and SWITCH OFF the amplifier IMMEDIATLY. Investigate the cause for the protection circuitry to trip, such as a short circuit in any of the speaker leads or any wire touching an adjecant terminal at either the amplifier's or loudspeaker's end. If overheating was the cause (the amplifier's casing will be very warm) ensure the ventilation slots at the bottom and top are not blocked. Wait for a couple of minutes for the amplifier to cool down before switching it on again. If the protection circuitry remains engaged, even after the amplifier has cooled down sufficiently and all NAD 5 The Bass control adjusts the relative level of the low frequencies in the sound. The response of the amplifier is flattest when the control is set in the detent at the 12 o'clock position. Rotation of the knob to the right (clockwise) increases the level of low-frequency sounds, and rotation counter-clockwise decreases their level. At moderate rotations away from center the effect of the Bass control is subtle, because its action is Connections have been checked you will have to consult your NAD dealer. [. . . ] Check the concentric volume control and ensure that both left and right are at an equal level. Transformatorn (baktill till vänster) alstrar ett medelstarkt magnetiskt brumfält och en skivspelare bör därför inte placeras direkt till vänster om den. Anslut kabeln från vänster högtalare till uttagen (L+) och (L-), anslut kabeln från höger högtalare till uttagen (R+) och (R-). Anslut en stereokabel från TAPE OUTuttaget på förstärkaren till inspelningsenhetens LINE IN-uttag och en andra kabel från inspelningsenhetens LINE OUT-uttag till TAPE IN-uttagen. [. . . ]
