Offering a level of sound quality that is recognised as being far above competing receivers, the AVR390, AVR550 & AVR850 are audiophile products by any measure. Equally at home with high resolution surround sound or two-channel music, they deliver stunning realism with everything from heavy- weight blockbusters to your favourite concert video.
Laden with all the inputs and features that you could want, these new products from ARCAM deliver a new level of performance due to the marriage between ARCAM amplifier design and DIRAC Live room correction technology.
Dirac Live - What's all the fuss about?
This fabulous piece of software works in conjunction with the audio response of your loudspeakers and the room. When setting up, all the usual considerations have to be taken into account, especially loudspeaker placement. Once this is done, the installer/user moves to the setup programme.
The first steps into the sound field
Firstly the signal to noise ratio needs to be set within the room. Too quiet and the dynamics are 'squashed', too loud and the dynamic range is reduced. The level is set to -24dB. This is just right to maximise on dynamics and dynamic range. Each channel is set to this level by using the test tones that we are all familiar with in home cinema. At that's where the similarities stop!
It is measured using a very sensitive specialist microphone and a series of signal sweeps. The microphone is positioned in 9 spots around the main seating area. This is to give the extended sound field for the listener/s rather that the usual 'Hot Spot'.
Manipulating the sound.
Once the signal sweeps have been done the programme works out the frequency response of the system within the room. The most important part of these graphs is the spikes which are areas of resonance and the 'killers' of performance. These are the areas that need manipulation and with a little intuition and skill, will yield significant results.
What makes DIRAC Live so very different, is that it can be manipulated by the experienced Installer/User to maintain the presentational characteristics of the loudspeaker, whilst gaining extra clarity and dynamics whose end result is a fantastic 3 dimension soundstage with pin-point object placement within this sound field.
Together with Arcam’s legendary amplifier technology, Dolby Atmos & DTS:X The new ARCAM AVR's deliver a captivating sound that place and movies and audio with pin point precision anywhere in the room to bring entertainment alive.
