Dolby TrueHD
The DENON A1HDA has
Dolby TrueHD which is a next-generation lossless technology developed
for high-definition disc-based media. It delivers sound that is bit-for-bit
identical to the studio master at a bit rate of up to 18 Mbps. It also supports
up to 8 full-range channels of 24-bit/96 kHz audio (although TrueHD can support
more than 8 channels, HD-DVD and Blu-Ray standards limit it to 8) and extensive
metadata including dialogue normalization and dynamic range control all through
an HDMI connection. Dolby TrueHD is compatible with existing and future AV
amplifiers/receivers.
DTS-HD
The DENON A1-HDA has DTS-HD which has been selected as an optional audio technology for Blu-Ray
Disc and HD-DVD. DTS-HD is a set of extensions to DTS' Coherent Acoustics audio
coding system which encompasses DTS Digital Surround, DTS-ES 6.1 discrete, DTS
Neo:6 and DTS 96/24. As a mandatory technology in the next generation standards,
a DTS decoder will be built into every HD-DVD or Blu-ray Disc player. A single
DTS-HD data stream on a disc can carry everything from standard DTS 5.1 playable
on virtually all existing 280 million plus DTS decoders, all the way to lossless
for next-generation systems.

Dolby Headphone▲
| |
| |
Dolby Headphone attempts to recreate the effect of a full 5.1 system through your headphones, allowing you to experience the sound as if you were listening to your speakers. This is advantageous for those who enjoy films late at night or who have children so cannot have the volume up as loud as they would like, but still get an approximation of the surround effect through their headphones.

Audyssey Dynamic Volume and Dynamic EQ▲
| |
|
Audyssey Dynamic Volume
Soundtracks are often recorded with volume spikes, and switching between sources can lead to big differences in volume;
setting the volume at any given time does not take these differences into account. Having Audyssey Dynamic Volume on will
set the volume at a steady constant and will increase or decrease depending on the content, ensuring you are not troubled
by spiking volume late at night.
Audyssey Dynamic EQ
Dynamic EQ ensures that when you turn down your surround sound, channels don't drop out completely. It calculates the
difference between reference and playback level to keep the surround channels in check when the volume is turned down.
Using the information collected by MultEQ/XT/XT32, the volume is corrected according to the particular acoustic properties of
your room.

HDMI 1080p Upscaling by HQV Teranex Realta processing (720p/1080i scaling to component)▲
| |
|
Video Upscaling
Video content comes in many different shapes and sizes. A DVD, for example, could come in a 4:3 aspect at 480p whilst a
Blu-ray or computer game may come in a 16:9 aspect at 1080i. Thse signals must first be processed by either an A/V
receiver or by your television in order to display correctly. In the first instance, when upscaling from 480p to 1080p,
an algorithm is used to interpolate the original pixels. The end result is a largely new frame; many of the pixels displayed
are an average of those around them. In the second instance, from 1080i to 1080p, the image is simply deinterlaced. This
process precedes any upscaling, so if you upscale from 480i to 1080p, it will first be deinterlaced before being upscaled.

THX Ultra 2
THX certified products are sent to the THX test facility for rigorous testing. Often this will mean revisions must be made to
the design or components used in order to pass the tests. THX certified products show that exact standards set by THX have been
met. Ultra2 is given to products that are ideally designed for larger rooms (approx. 3000 cubic feet) with a 12+ foot viewing
distance from the screen.

High Definition Multimedia Interface (HDMI) is the first industry-supported, uncompressed all-digital audio/video interface. HDMI provides a connection between any compatible video source (DVD player, Blu-Ray Player, set-top box, games console, etc) and an A/V receiver or HDMI compatible television or projector. It supports standard definition and high definition video, along with multi-channel digital audio (including lossless Dolby TrueHD and DTS-HD found on Blu-Ray) on a single cable. It transmits all ATSC HDTV standards and is retro-compatible with DVI-D.

Digital Living Network Alliance (DLNA)
DLNA is an agreed standard for sharing media from your computer across your home network to devices like this. This can be
digital photos, music and videos. Not all devices are capable of playing back all media, some only playback audio.

Toroidal Transformers
Usually found in higher-end equipment, these transformers are designed around a ring-shaped core, improving efficiency by reducing
magnetic resistance. Effectively, a toroidal transformer helps to reduce the
transference of unwanted noise to the audio circuitry
by retaining the interference in the transformer core. Coils are wound around the surface of the core which minimises the length of
wire needed whilst at the same time screening the core’s magnetic field to reduce electromagnetic interference. These transformers can
also be more efficient than their cheaper counterparts. They produce less mechanical hum and a lower exterior magnetic field,
and have low off-load losses so they are efficient even in standby.

Digital to analogue converter (DAC)
Converts the digital data signal into analogue signal that can be amplified and reproduced using speakers or headphones so that our ears can hear it.
In the case of video the data is converted into a video signal that can be reproduced by a display device so that we can see it.
Once data is converted to an analogue signal it then can degrade and lose its quality every step of the way. Most modern equipment is designed to keep data in the digital (Lossless) domain as long as possible.
In an ideal world data would be kept digital right up until the point that you see or hear it avoiding degradation.

Bi-Amping allows you to use any spare amps you have on your A/V Amplifier to get the most out of your front speakers. To do this your front speakers need to be biwireable (Have two sets of terminals marked HF and LF) and you need to run bi-wire cable. You also need to have two spare channels. So for example if your are using only 5.1 speakers you can use the other two channels for Bi-Amping
