Denon keep upping the ante with more advanced features packed into its new AV surround receivers to satisfy demanding home theatre enthusiasts, plus lowering price points to maintain competitiveness. The AVR-2105 is a great example of what you would want and expect from an advanced 7.1-channel surround receiver in terms of value for money. This new addition sits in the middle of the range, but is definitely not middle of the road.Design
The AVR-2105 is typical of Denon's AV receiver design, with fairly standard component dimensions of 434 x 171 x 417mm but substantial heft at 13.3kg. Available in silver and black, the AVR-2105 has a freshly designed front panel with two main dials located either side of the large central display section. The left dial selects the source while the right controls the volume and below this is a smaller dial is used to switch between different sound field modes. A number of small function buttons also adorn the face in a neat and ordered fashion below and around the display.
While the layout would not be too challenging for an advanced user, newcomers would almost certainly have to refer to the thick manual to learn to make the most of its features. These features can be accessed directly or through the full function remote control, which while logical, takes some time in becoming familiar.
Having said this, perhaps the most advanced and outstanding features of the AVR-2105 is its automatic speaker and time correction function. The receiver comes equipped with an auto set-up calibration microphone to ensure the best performance from the speakers in whatever environment it is installed.
The AVR-2105 has an impressive specifications list beginning with seven channels of 90 watts continuous into 8 ohms including the two surround back channels. High quality sound reproduction is entrusted to a new Analog Devices Hammerhead SHARC high resolution 32-bit floating point DSP with advanced surround sound format decoding including DTS-ES 6.1, DTS 96/24 5.1, DTS Neo: 6, Dolby Digital EX and Dolby PLIIx. There are also a number of other sound field modes to choose from for your different sources.
