SETTING UP THE L73

GETTING STARTED

Before you make the first connection to your L73, you should have the arrangement of your listening room/home theatre components and furniture mapped out, at least initially. Unfortunately, a discussion of the vital questions of loudspeaker placement and listening/viewing positions is beyond our scope here. Suffice it to say that these two questions will influence your system’s ultimate performance every bit as powerfully as your selection of electronics and speakers. Your NAD audio specialist dealer will be happy to advise you, and to recommend reference materials.

NOTE

It is not absolutely necessary but one may find it easier to use the HTR L73 remote handset in conjunction with the front panel buttons to configure your L73. See “Using the HTR L73 Remote”.

DEALING WITH HUM AND NOISE

Hum and noise sometimes prove a challenge in complex, multichannel audio systems. Note these considerations to help prevent hum and noise problems:

Power your system’s entire audio components from AC outlets originating from the same circuit of your house wiring. As far as possible, power all audio components from the same outlet, or adjacent outlets on the same circuit. It may be useful to power video displays (and computers!) from outlets on another circuit, especially if that circuit is supplied from the other “leg” of the house wiring.

Do not bundle analog audio cables with AC power cables, or with coaxial digital-audio cables. It is best if they cross at right angles if they must be in close proximity.

Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are secure.

A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, low- resistance contact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging and re-plugging, since the gold (or copper) contact plating of typical cable connectors, even very high- quality ones, is very thin and easily worn.

Track down hum/noise problems one component at a time, working backwards from the receiver. That is: Connect the speakers to the receiver only, and check for hum. Then connect one component only (a VCR, for example) alone, with no other components connected and check for hum. Connect additional components, one at a time, to the receiver and check for hum. At each stage, if hum/noise appears, examine the audio cabling and AC-power routing of the new component. In some cases, moving the new component’s AC cord to a different outlet, or installing a ground-lift (3-to-2-prong adaptor) on its power cord, will eliminate the hum.

ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT

The L73 receiver employs two; self-explanatory systems of on-screen display “menus” one for the L73 receiver, the other for the internal DVD player. These “menus” will appear on the connected video monitor/TV and are required during the setup process (useful in day-to-day operation); so be sure to connect the monitor/TV before proceeding with setup.
