Benchmark Media Systems, Inc. published test results regarding the performance of an iPad connected to a Benchmark DAC1 converter via USB. According to their findings, the iPad is capable of streaming high-resolution 24-bit digital audio at sample rates up to 96-kHz. No software is required. Apple's low-cost 'Camera Connection Kit' adaptor provides the USB connection.
"This is very exciting because audiophiles can now enjoy using the iPad as a high-resolution music server," says John Siau, VP and Director of Engineering. "Benchmark's driverless AdvancedUSB system operates as a native USB audio device and is ideally suited for iPad applications. The versatility of the iPad is now coupled with Benchmark's highly respected D/A converters. Benchmark DAC1 converters are used in many of the world's top recording studios and high-end home hi-fi systems."
Out of the box, Apple's iPad tablet computer can be used to watch videos, read e-books, surf the web, and listen to music. In addition, there are currently over 90,000 applications available from the Apple App store. Many of these applications have audio functions. According to Siau, "The 'Camera Connection Kit' redirects all of the iPad's audio output to the Benchmark DAC1, as soon as it is plugged into the iPad. All iPad applications now have a transparent digital connection to the DAC1's state-of-the-art audio system. This high-resolution digital connection offers a vast improvement over the limitations of the iPad's built-in headphone jack. In combination, the iPad and DAC1 can deliver studio-quality audio with outstanding versatility and usability."
"We performed a suite of tests on the system performance using an Audio Precision test station," says Elias Gwinn, Applications Engineer. "What we found is that the DAC1 performs to full specifications when connected to an iPad. In fact, the DAC1's performance is exactly the same when connected to other sources, such as a Mac computer, via USB or optical. Bottom line, the iPad can deliver studio-quality audio, when connected to a DAC1."
