Because all of the T748’s HDMI sockets are v1.4, it’s fully geared up to pass 3D images through to your TV, as well as supporting Audio Return Channel and CEC. It’ll also convert analogue video signals and output them from the HDMI socket.
Naturally it can also decode any Dolby and DTS format, including Dolby True HD and DTS HD Master Audio, plus stereo material can be converted to pseudo surround using NAD’s EARS mode, Dolby Pro Logic IIx or NEO:6 (but there’s no ‘front height’ technology like Pro Logic IIz). Enhanced Stereo plays music through all speakers. Power output is quoted at a modest 7 x 40W, although in stereo mode that’s upped to 2 x 80W.
Setup is simple thanks to the built-in Auto Calibration. Using the supplied microphone and test tones, it sets the appropriate noise level, number of speakers, distances, levels, sizes and equalisation (bass/treble levels) for your room automatically. It’s a set-and-forget process, perfect if you hate the thought of tweaking everything manually.
But if you’re not happy with the results then you can turn off the EQ after calibration is complete, or set the parameters yourself in the setup menu. This comes in the form of a rudimentary onscreen display, with blocky lettering over a black background. Its ugly appearance is a far cry from the slick menus of Onkyo and Denon, but it’s responsive and easy to follow.
Within it, you can tinker with the speaker settings, configure the inputs, alter listening modes and loads more – despite its simple appearance, it’s very thorough. Also useful is that it remembers your settings for each source input.
The T748 comes with an attractive, weighty remote. It’s covered in rubbery, tactile buttons and a helpfully placed menu control pad. Button size and labelling is excellent, and the row of ‘device selector’ keys along the top is useful. It can also be used to control other NAD components.
