Here is a photo of the AV connections on the rear panel of the T748 located on the top left.

Starting on the left side are the AM and FM Radio antenna connections.

Moving right are two Composite (yellow) video inputs one composite video output, one S-Video input, and one set of Component Video (red, green, blue).

Below the video connection are three sets of analog stereo connections (red/white), and one set of analog stereo output connections.

It must be noted that there is no direct connection provided for phono turntable. You cannot use the analog audio inputs to connect a turntable because the impedance and output voltage of a turntable cartridge is different than other types of audio components.

If you desire to connect a turntable, you need to use an external Phono Preamp, that goes between the turntable and the T748 or purchase one of increasing number of newer turntables that have built-in phono preamps that will work with the audio connections provided on the T748. If you are planning to purchase a turntable, check to see if it has a built-in phono preamp.

Finally, shown along the bottom row is an IR sensor repeater cable input (which can be used to allow control of the T748 using an another control device), an MP Dock Data Port (for connecting the optional iPod/iPhone dock), and an RS-232 interface connection. The RS-232 connection is provided for more sophisticated control functions in custom installations.

Shown in this photo is a set of 7 channel analog audio preamp outputs. These preamp outputs can be used to connect more powerful amplifiers to the T748, to be used in place of the T748's own internal amplifiers. When using this type of setup, the T748's other functions, such as audio processing and switching can still be accessed. NOTE: The Subwoofer preamp output connects to a powered subwoofer.

Finally, taking up the rest of the rear connection panel are the Speaker Connections.

Here are some of the speaker setups that can be used:

1. If you want to use a full traditional 7.1/7.1 Channel setup, you can use the Front, Center, Surround, and Surround Back connections.

2. If you want to Bi-Amp your front main speakers (some speakers have separate terminals for the tweeter/midrange and woofer sections). You can re-assign the Surround Back speaker terminals for this function.

In addition to the physical speaker connections, you will also need to use the menu setup options of the receiver to send the correct signal information to the speaker terminals, based on what speaker configuration option you are utilizing. You also have to remember that you cannot use the surround back and bi-amping options at the same time.

Here is a look at the Setup Menu for the NAD T748 Receiver.

The is divided into seven sections.

Source Setup allows you set the parameters for each source, such as the source name, designation of the analog or digital audio input, and assignment of an A/V preset profile.

Speaker Setup provides all the settings need to manually set all speaker levels, distances, and crossover for each channel. A Test Tone is provided. On the other hand, if you take advantage of the NAD Auto Calibration System, this will all be done automatically for you. But you make further tweaks afterwards.

Amplifier Setup allows you to assign the 6th and 7th channel amplifiers to either the surround back speakers or to front speakers that support Bi-amp connections.

HDMI Setup provides for the activation of extra HDMI two-way communication features, such as CEC (Consumer Electronics Control), which allows source selection, power, and volume to be controlled on compatible HDMI-connected devices that are connected to the T748. Also, this menu also you to assign the incoming HDMI audio signal to be decoded and/or processed by the T748, or passed through to a connected TV instead. Lastly, this menu allows activation of the Audio Return Channel feature when connected to compatible TVs.

Listening Mode Setup provides the user with several options for setting preset listening mode options for Dolby and DTS surround format decoding and processing, as well as additional settings for Enhanced Stereo operation.

Display Setup allows you to set how you want status information displayed on the front panel VFD (Vacuum Fluorescent Display) and OSD (On-Screen Display).

AV Presets Setup allows you to manage and customize audio settings (such as listening modes, sound processing options, tone controls, speaker setup, and display setup). In other words, you can create setting profiles for different types of music, TV, and movie audio listening and assign each preset to one or more inputs as their default setting profile.

Here is a look at the Speaker Setup Menu for the NAD T748 home theater receiver.

You have the option of either using the Automatic Speaker Calibration feature, or going through each the three sections manually. In either case, a plug-in microphone (that can be mounted on a camera tripod) and built-in test tone generator are provided.

NAD T748 Home Theater Receiver - Speaker Settings Auto-Calibration Results

Here is a look at how the NAD T748 provides the user with information on the speaker setup. If using the automatic speaker setup system, everything shown in these menu examples is performed automatically. However, if you choose the manual speaker setup option, you will also have access to these menus and can set your own parameters as shown.

In both cases, built-in test tones are provided to assist in speaker setup. It is also important to note that if you are not satisfied with the calculations, you can go in and change one or more settings manually as well, if desired.

The image on the top left shows the Auto-Calibration Start Menu. You can set it for 7.1 or 5.1 channels. For this example, the Auto-Calibration System is set for a 5.1 channel setup.

The image on the top right shows what speakers are connected, their relative size, and assigned crossover points. In this case, five speakers and a subwoofer have been detected and the assigned crossover point is 100Hz.

The image on the bottom left displays the calculated speaker levels. This is done automatically when using the Auto-Calibration System. However, if you are doing the speaker setup manually, you can use the T748's test tone generator and either your own ears or a sound meter to set the proper channel levels.

The image on the bottom right shows the distance of the speakers to the primary listening position. If using the system, this calculation is done automatically. If doing this manually, you can enter your own distance measurements.

To conclude this photo profile of NAD T748 home theater receiver is a look at the Listening Modes menu.

This menu provides access to options for setting up the overall listening mode parameters, which include how an incoming signal is to be decoded or processed, as well as providing options for setting up the parameters for Dolby and DTS surround formats independently. The Enhanced Stereo option allows you to designate which speakers you want to be active when selecting the Enhanced Stereo listening option.

Final Take

As illustrated in the photo profile, the NAD T748 has a clean, uncluttered look. In using the T748 I found that the although it doesn't offer a lot of frills (there is no video upscaling, no dedicated phono input, no 5.1/7.1 channel analog audio inputs, and no Zone 2 option), it does provide great core features and audio performance in both stereo and surround operation. The needed connectivity for custom install control functions are also included. The T748 also has excellent build quality and even includes two internal cooling fans.

The suggested price for the T748 is $900, which I think is a little high for its feature set, and I have reflected that in my overall rating, but if you are looking a home theater receiver that delivers great audio performance and do not need the extra frills that normally come with home theater receivers in this price range, the T748 might be the right choice for you.

For additional details, perspective, and my final rating on the NAD T748, read my Review.
