Although the Azur 751R is a sophisticated piece of home-theater equipment, you wouldn’t know it from its modest size: It measures 16.9”W x 5.9”H x 16.5”D and weighs 38.3 pounds. If you’re a neat freak, the 751R is not for you — all of its many buttons are out in the open. The advantage of that is ease of use — no guessing which knob or button does what. In the middle of the faceplate is a blue display; to the right of that is a large volume-control knob, and below it is a line of buttons for directly accessing your sources. Running along the bottom of the front panel are the On/Off button, DSP mode selection, and buttons to operate the tuner, Zone 2 selection, and picture adjust. Near the On/Off button is a jack for the headphone output, which incorporates Dolby Headphone, which creates up to 7.1 channels through any pair of headphones. On the right side are inputs for HDMI, left and right analog audio, composite and S-video, optical digital, and a line-level MP3 jack.
Around back are five HDMI v1.4 inputs and two outputs — a nice touch, as most receivers have only one HDMI output. If you have many digital devices, Cambridge Audio looks after you with nine digital inputs: four optical, five coaxial. They also supply two optical and two coaxial digital outputs, which are rarely seen in A/V receivers. A USB type-B socket is included for streaming music from an HTPC or laptop computer. Seven pairs of RCA jacks are provided for analog sources — more than enough for most home-theater systems. The Azur 751R also accommodates, with two subwoofer outputs, the growing trend of using dual subs. However, these outputs are identical and can’t be individually set, as you can do with some receivers these days. There are seven pairs of color-coded speaker binding posts, and Zone 2 has component-video output as well as a subwoofer output.
