The T748's advanced video capabilities help streamline your system setup. 3D-ready HDMI inputs let you hook up your four best high-def components for easy switching. Analog-to-HDMI conversion sends all of your video sources to an HDMI-capable TV via a single-cable digital connection.

    Audio Features

    Amplifier Section: The T 748 is rated using NAD's Full Disclosure Power; 40 watts continuous output x 7 channels with all channels running simultaneously from 20-20,000 Hz into 8Ω loads with no more than 0.08% THD. The stereo output is 80 watts continuous x 2 channels under the same conditions.

    Auto Calibration: The auto setup and calibration feature uses the included microphone, along with sophisticated digital electronics to automatically setup and calibrate the T 748 to the exact speakers and speaker placement of your unique home theater. The receiver automatically checks what speakers are connected, measures and adjusts each speaker's distance (delay time), relative level (volume), and size (crossover point). The speakers can also be adjusted manually if you prefer.

    Amplifier Setup: If no surround back speakers are used, the surround back amplifier channels can be reassigned to Bi-Amp the front left and right speakers (if they have bi-amp inputs).

    Listening Modes: The T 748 offers decoding for all the latest surround formats including Dolby Digital, Dolby TrueHD, Dolby Digital Plus, DTS, and DTS-HD Master Audio; as well as Dolby Pro Logic surround processing.

    Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the A/V receiver via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.

    Listening Mode Parameters: The T 748 provides the following Listening Mode Parameter adjustments for Dolby Pro Logic IIx and DTS NEO:6.

    • Center Width (DPL IIx): Modifies the "hard-centeredness" of the center image, by gradually mixing mono center content to the Front left/right speakers as well. A setting of 0 retains the center-channel-only default while a setting of 7 yields a fully phantom center channel.
    • Dimension (DPL IIx): Adjusts front-rear emphasis of the surround effect independently from the relative channel levels.
    • Panorama (DPL IIx): Adds a "wraparound" effect by extending some stereo content into the surround channels.
    • Center Gain (DTS NEO:6): Adjust for better center image in relation to the surround sound channels.

    EARS: Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD surround processing with signals output to the front left/right, center and discrete left/right surround channels, plus subwoofer. EARS extracts the natural ambience present in nearly all well-produced stereo recordings. It does not synthesize any ambience or other sonic elements and thus remains truer to the sound of the original musical performance than most other music-surround options. EARS offers realistic, stable "front-stage" sonic imaging and spacious but unexaggerated ambient "virtual acoustics" that remain faithful to the original recording. Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly natural and believable ambience from nearly all "natural-acoustic" stereo recordings. Typically, these include classical, jazz, and folk genre.

    Stereo Modes: The NAD T 748 also provides two-channel stereo and multi-channel stereo playback, as well as an analog bypass stereo mode.

    • Stereo: All output is directed to the front left/right channels. Low frequencies are directed to the subwoofer if one is present in the Speaker settings. Select 'Stereo' when you wish to listen to a stereo (or monaural) production, such as music CD or FM broadcast, without surround enhancement. Stereo recordings whether in PCM/digital or analog form and whether surround-encoded or not encoded, are reproduced as recorded. Multi-channel digital recordings (Dolby Digital and DTS) are reproduced in "Stereo Downmix" mode via the front left/right channels.
    • Enhanced Stereo: All recordings are reproduced in stereo via the maximum speaker complement. Enhanced stereo can be useful for maximum volume from all channels or for multi-speaker background music (cocktail party) listening. For this mode, Front, Center, Surround and Back speakers can be turned ON/OFF as desired.
    • Analog Bypass: All analog signals remain in the analog domain without analog-to-digital conversions. At Analog Bypass, the DSP circuitry is bypassed but full tone control functions remain. 'Bass management' or Speaker settings are also not in effect as these are DSP functions.

    A/V Presets: Five A/V presets can be stored with customized settings for listening mode, DSP options (lip sync delay), tone control, speaker setup, and front panel display.

    Tone Controls: Bass and treble can be adjusted +/- 10 dB.

    Audio Inputs/Outputs: The NAD T 748 offers a variety of analog and digital audio inputs/outputs.

    • Assignable Inputs: Six of the T 748's seven inputs are assignable (the source 5/iPod input is fixed as analog audio 2 and S-video 1); you can program the name (as displayed on the front panel and OSD, up to eight characters), analog input, gain setting (+/-12 dB in 3 dB steps to match the other sources), digital audio input, and video input to match a given source selection.
    • Digital Inputs/Outputs: There are two coaxial digital inputs and three optical digital inputs (one front). The inputs accept digital audio signals from a digital TV, Set top box, Blu-ray player, compact disc, DVD, LD, or other digital source components; each can be assigned to a specific source using the on-screen menu.
    • Preamp Outputs: The T 748 features Front left, Front right, Center, Surround left, Surround right, Surround Back left, Surround Back right and Subwoofer preamp outputs to connect the receiver to external power amplifiers.
    • Speaker Terminals: The receiver has binding post speaker terminals for the front, center, surround, and surround back channels. The binding posts can accept bare wire, pin connectors, and single banana plugs. The terminals are spaced too far apart for dual banana plugs and a collar surrounding the terminals prevents the use of spade connectors.
    • Headphone Output: The receiver features a 1/4" stereo headphone jack on the front panel for connecting an optional pair of headphones. The unit's speaker outputs are automatically muted when a set of headphones is connected.

    Video Features

    Video Conversion: The T 748 takes each analog video input (composite video, S-video, and component video), digitizes it and sends it out through the HDMI monitor output (the S-Video input is also output through the composite video monitor output). The on screen display is also output through all of the monitor outputs.

    HDMI Inputs/Output: This unit has four HDMI inputs and one HDMI output. The inputs are assignable using the receiver's on-screen menu. The T 748 will convert composite video, S-video, and component video to HDMI.

    ARC (Audio Return Channel): HDMI (1.4) also features an Audio Return Channel, which allows both audio and video content to be sent through a single HDMI cable. This eliminates the need for separate audio and video cables running from your TV to the receiver.

    3D Pass-Through: With the advent of 3D media, it is important to own a receiver that passes 3D video signals. The T 748 is able to pass 3D signals from your Blu-ray player to your TV via the HDMI connection.

    Lip Sync Delay: Video signals may take longer to process than audio signals, depending on the connected video equipment. The audio signal can be delayed up to 120ms to synchronize with the video signal.

    Component Video Input: The one component video input is also assignable using the receiver's on-screen menu.

    Composite Video Inputs/Output: There are three composite video inputs (one front, two rear) and one composite video monitor output; the inputs are assigned to specific sources using the on-screen menu.

    S-Video Inputs: There are two S-video inputs (one front, one rear). The rear input is assigned to the iPod input (source 5). The rear input can also be assigned to other inputs, in addition to source 5.

    Front-Panel A/V Input: The receiver features a front-panel A/V input which consists of composite video, S-video, stereo RCA, and optical digital jacks. There is also a 3.5mm stereo mini-jack input on the front panel.

    HDMI Pass-through: When the T 748 is in standby mode (power off), the HDMI source signals will continuously pass through the receiver to the TV. The HDMI Control (CEC) feature must be enabled in order for HDMI Pass-through to work.

    Remote Control

    Main Remote: The AVR 4 remote controls the T 748 and is pre-coded with controls for other NAD components.

    Remote Connections: The NAD T 748 is fitted with the following custom remote inputs/outputs.

    • IR In: The 3.5mm IR In allows you to connect the T 748 to an infrared repeater.
    • RS-232C: The RS-232C port is to be used in conjunction with an external controller; AMX, Crestron or a compatible PC using NAD's proprietary PC software.

    Switched AC: The maximum output on the 2-prong switched AC outlet on the rear panel is 100 watts/1 amp.

    Add-on Devices

    iPod: The optional IPD 2 iPod dock (item number 745IPD2, sold separately) plugs into the MP Dock jack, S-Video, and Audio 2 (default iPod inputs) on the rear panel and allows audio, video, and pictures stored on your iPod to be played directly on your home Theater. The IPD 2 also charges your iPod's battery.
