Dolby Pro-Logic IIzMore Info...
Dolby Pro-Logic IIz▲
Dolby Pro-Logic IIz
Taking a 5.1 or 7.1 mix, Dolby ProLogic IIz is able to expand it by creating four new (non-discrete) channels for up to 9.1
surround sound. The system is flexible so you can add new speakers where you want. For example, if you currently have a 5.1
set-up then you can add height channels above your current left and right speakers or you can have them behind you for a more
traditional set-up. Of course, you can always have both and take full advantage of what ProLogic IIz has to offer, with 9.1
surround sound.
A standard 5.1 with newly created height speakers as a 7.1 system.
This new 7.1 set-up can then be expanded by adding two further channels as surround sides for 9.1 channels.
Dolby VolumeMore Info...
Dolby Volume▲
Dolby Volume allows for on-the-fly volume equalisation. This can be useful when watching TV with large differences in volume such as when a TV program has loud adverts
Audyssey DSXMore Info...
Audyssey DSX▲
Audyssey DSX
Audyssey DSX can add up to four new (non-discrete) channels to your home cinema. It does this by using an algorithm to
find the relevant information in the pre-existing soundstage and then distributing it amongst the new channels. These
channels are processed and checked simultaneously for any inconsistencies or potential clashes with the discrete channels.
A number of different combinations are possible. Audyssey DSX allows for up to an 11.2 system by adding front width and
height speakers to a 7.1 mix.

Audyssey MultEQ® XT for Room Acoustic Correction▲
Audyssey MultEQ XT
MultEQ XT attempts to calibrate your system to perform as best as possible given the often less-than-ideal room shaped and
materials (such as glass) present in your home cinema. All this is done in a matter of minutes with the included microphone
and the results may range from sharper vocals to a better spatiality to the soundstage. The XT improves on the original MultEQ
to give a better performance with higher-resolution equalization filters.
Audyssey Dynamic EQ and Dynamic VolumeMore Info...
Audyssey Dynamic EQ and Dynamic Volume▲
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.
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.

High Definition Multimedia Interface (HDMI) v1.4
The HDMI v1.4 connections on the ONKYO TX-NR809 allows for the transmission of 1080p 3D content between a
3D-compatible Blu-Ray Disc player and a 3D HD display. It also brings in
an audio return channel allowing for two-way transmission of audio. This
allows your television, for example, to send audio back from its
integrated tuner to the receiver, solving the problem of having to run
more than one cable between your A/V receiver and TV.
HDMI video upscaling to 4k with Marvell Qdeo video processingMore Info...
HDMI video upscaling to 4k with Marvell Qdeo video processing▲
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.
Marvell Qdeo
Qdeo is a video processor which seeks to remove any errors inherent in the source and to improve the overall picture quality.
It removes noise, artefacts and "jaggies" on a pixel-by-pixel basis to get the very best from the source itself. It then applies
contrast enhancement, colour remapper and depth expansion technologies with the aim of achieving a more natural image than previously
available.
Dual HDMI outputsMore Info...
Dual HDMI outputs▲
The Onkyo has two HDMI outputs; HDMI Main and HDMI Sub. The HDMI Main has Audio Return Channel and the GUI (Setup menus). The HDMI Sub just displays the selected video source. Dual outputs are useful if you have two display devices such as a Plasma/LCD TV & a projector or if you wanted to run the video signal to another room.

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.
A negative feedback design circuit counters distortion by cancelling it out with an opposing phase of the output signal into the input stage. An inherent problem with this design is it is susceptible to interference from the speakers, causing more circuit noise. This Onkyo-designed circuit seeks to improve on this design with three transistors the signal must pass through. The negative feedback required is therefore less, and so there is less circuit noise.

IR in/out and Zone 2/3 12v trigger output▲
Useful for custom installation. IR Inputs and Outputs allow 3rd party RF (Radio Frequency) remote controls to connect at the rear of the receiver and pass the codes that would normally be transmitted via infrared directly to the receiver. The IR output allows this to be looped through to other equipment. The Zone 2/3 12v trigger outputs allows 3rd party items like a projection screen to be controlled.
VGA inputMore Info...
VGA input▲
If you have an older PC that doesn't have HDMI or DVI-D, you can use this VGA monitor port to connect video only (Audio must be passed separately to the AV Receiver.)
Bi-Amping capabilityMore Info...
Bi-Amping capability▲
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
Powered Zone 2 option and Zone 2/3 preoutsMore Info...
Powered Zone 2 option and Zone 2/3 preouts▲
Zone 2 allows you to be watch/listening to a separate input in another room. For example one person might be watching a Blu-Ray in one room and another could be listening to the radio. If you are only using 5.1 you can assign the extra channels of amplification to Zone 2.
