User manual NAD 7125

[. . . ] Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1. Mount antenna discharge unit as close as possible to where lead-in enters house. Do not place this unit on an unstable cart, stand or tripod, bracket or table. The unit may fall, causing serious injury to a child or adult and serious damage to the unit. [. . . ] the volume and tone and balance controls are operative for headphone listening. Use a suitable adapter to connect headphones with other types of connectors, such as 3. Warning: Make certain that the volume control is turned to minimum (fully anti-clockwise) before connecting headphones. The main speaker outputs (Speaker A) are always active unless headphones are being used. It is motor driven and can be adjusted from the remote control handset. The VOLUME control does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out). The NAD-71255 is fitted with BASS and TREBLE tone controls to adjust the tonal balance of your system. The 12 o'clock position is `flat' with no boost or cut and a detent indicates this position. The Tone controls do not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out). Use the mono switch when the source signal is present only on one of the input channels (left or right) or when receiving weak and hissy stereo FM signals. When the NAD-71255 is put into Mute mode from the Remote Control handset a flashing `MUTE` will be displayed on the left hand side of the display. And it cannot easily be rotated to optimize its pickup pattern for best reception of stations in different directions. The recommended options, in order of increasing cost, are as follows: (1) A basic "rabbit-ears" indoor TV antenna without auxiliary coils or tuning switches. electrically , such an antenna is just another dipole (similar to the ribbon-wire antenna). But since its tuned elements are made of metal rods, it can easily be rotated. Stretch out each of its two arms to a length of 30 inches (75 cm), and orientate them horizontally or at a shallow angle (less than 45 degrees upward). The ribbon wire emerging from the antenna's base should be connected to the balun adapter's screw terminals in place of the simple ribbon-wire antenna. Now, for each station in turn, after you tune the station you can rotate the antenna for best reception. (2) A more elaborate rabbit-ears indoor TV antenna with a tuning switch. This type of antenna does NOT have greater sensitivity than the simpler rabbit-ears unit, so if your problem is that the signals you want to receive are weak and noisy, an outdoor antenna is the only effective solution. But in cities and in large buildings, where signals are strong but are contaminated by reflected "multipath" signals that interfere with reception, the tuning switch on an elaborate indoor antenna may reduce the interference. Again, such antennas may not provide any advantage over the simplest type of "rabbit-ears" unit for receiving weak signals. [. . . ] If you have connected speakers this way, engage SPEAKERS B when you want to hear spatially enhanced surround-sound stereo. The amplifier contains two independent sections or stages: the control preamplifier (including the phono preamp and most front-panel controls), and the power amplifier (which provides the power to drive loudspeakers). In normal operation the preamp and power amp are connected together via factoryinstalled U-shaped metal jumpers that bridge the PRE-OUT and MAIN-IN jacks. Check to be sure that they are fully inserted into the jacks and that nothing is touching them. [. . . ]
