The NAD T747 is a 7 channel A/V surround sound receiver with dual zones that gives a good performance at a reasonable price. Each of the seven channels has 60 watts of simultaneous power (full disclosure), with 110 watts of power available in stereo mode. Although it does not offer the full level of customization as upper model receivers made by NAD, it uses the same remarkable flexibility of NAD’s highly refined User Interface for easy operation and setup. The Data Port can be used with optional NAD Dock for iPod giving you easy access to your digital music library. It supports a wide variety of sound modes, and unlike the T737 it supports Dolby TrueHD and DTS HD Master Audio lossless decoding. There are several inputs including four HDMI inputs with repeater function and three component inputs which can be used with two optical and two coaxial digital audio inputs for plenty of HD compatibility. There is also an AV output for a second zone allowing you to enjoy an independant source with independant volume settings.
