SETTING UP THE T 753

GETTING STARTED

Before you make the first connection to your T 753, you should have the arrangement of your listening room/ home theater 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: You will need the HTR 2 remote handset to configure your T 753. See “Using the HTR 2 Remote”, below.

DEALING WITH HUM AND NOISE

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

•Power all your system's audio component 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 CD player, 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 adapter) on its power cord, will eliminate the hum.

NAD has integrated their proprietary technologies into the T 753, notably the PowerDrive technology, which allows the receiver to efficiently manage power output across different impedance loads. This ensures that the T 753 maintains clarity and control even at high volumes, reducing the risk of distortion. Another key technology is the Soft Clipping feature, which gently limits the output signal when the system is pushed to its limits, preventing harsh clipping and preserving sound quality.

In terms of connectivity, the T 753 is versatile, equipped with multiple HDMI inputs that support both video and audio, making it compatible with the latest HD and 4K devices. The receiver also features component and composite video inputs, as well as digital and analog audio connections, ensuring it can integrate seamlessly into existing home entertainment systems.

The user-friendly interface of the T 753 includes an intuitive on-screen display that simplifies system setup and operation. Users can easily navigate menus and adjust settings to customize their listening experience. The inclusion of a remote control further enhances convenience, allowing users to control multiple devices from a single point.

One of the standout characteristics of the NAD T 753 is its capacity for multi-channel audio formats. It supports DTS, Dolby Digital, and other surround sound formats, creating an immersive audio environment ideal for movie nights or concerts. The receiver also includes a powerful built-in equalizer, allowing users to tweak audio frequencies to better suit their acoustics, ensuring a tailored audio experience.

In conclusion, the NAD T 753 represents a harmonious blend of power, versatility, and advanced technology. Its sound quality, coupled with comprehensive features and user-friendly design, makes it an outstanding choice for home theater enthusiasts looking to enhance their audio experience.
