Audio Research DAC8
23/7/2010
Audio Research introduces ingenious all new Hi Definition Converter.
As if DAC7?s success and the excellent reviews received world wide was not enough, Audio Research has decided to move things one step further by employing USB 2.0 Full speed to their new DAC8, capable of handling files up to 24/192.kHz
In the past, such resolution figures could only be found through S/PDIF connections, problem solved via the use of the Audio Research Dual Master Oscillator, allowing your USB port to be able to play back your favorite music files for the first time in high quality. Another break-through from these resourceful engineers at Audio Research. The retail price of DAC8 will be ~ $4900.
Details about DAC8:
• "DAC8 HD Audio Device" software drivers, which allow listening to your music in its native sample rate as well as assuring BIT PERFECT, low jitter, data transfer from the computer to your DAC8. Because PC and Mac operating systems do not adequately support sample rates over 96kHz, Audio Research has developed ASIO drivers to make the USB audio experience sonically transparent at all sample rates.
• Sample Rate measuring function: Measures and displays the correct digital sample ratebeing sent to the DAC8. This works in USB as well as S/PDIF mode. Consequently, at a glance, you always know exactly which sample rate is being decoded.
• The DAC8 employs four 24-bit D/A converters. Each channel uses dual 24-bit D/A converters running in mono mode to lower the noise floor and increase the dynamic range.
• Dual Master Oscillators: When the time base of any DAC is not an integer multiple of the digital music sample rate, decoding and quantization errors occur. Consequently, the DAC8 uses two low jitter Master Oscillators; one for 44.1, 88.2 & 176.4kHz sample rates and the other for 48, 96 & 192 kHz sample rates. The DAC8 automatically selects the correct Master oscillator the instant digital music is detected at the selected input.
• All inputs are galvanically isolated from the source to reduce or eliminate noise and/or jitter from entering the DAC8.
• The Analog amplifiers in the DAC8 have received the same attention to detail as the digital section. Each channel of the DAC8 uses a true direct-coupled differential amplifier with a bandwidth in excess of 90kHz.
• The DAC8's S/PDIF inputs are designed to accept signals from an HRx, 176.4kHz, 24-bit, High-Resolution music server system playing HRx's DVD-R recordings. See www.referencerecordings.com/HRxSETUPS.asp for recommended music server setups.
• By virtue of all of the above points and our proprietary software drivers , intrinsic jitter has been reduced to less than 10ps.
