Dr. AIX (Mark Waldrep from AIX Records) recently published an excellent application note titled "My First Server" - a simple step-by-step guide for setting up a High-Resolution Audio (HRA) server. Dr. AIX chose a Mac Mini, a Benchmark DAC2 HGC, and the highly-acclaimed Amarra playback software.
The result is a true High-Resolution Audio system that can deliver the finest studio-quality playback available. The Benchmark DAC1 and DAC2 converters have become standard fixtures in many of the world's top recording studios and mastering rooms. They have become the converters of choice for critical listening in these professional environments.
"My First Server" describes the server that Mastering and Recording Engineer Mark Waldrep uses in his own living room. With his simple guide, you can enjoy mastering-quality High-Resolution Audio playback.
At the 2023 AXPONA show in Chicago, I had the opportunity to see and hear the Hill Plasmatronics tweeter. I also had the great pleasure of meeting Dr. Alan Hill, the physicist who invented this unique device.
The plasma driver has no moving parts and no diaphragm. Sound is emitted directly from the thermal expansion and contraction of an electrically sustained plasma. The plasma is generated within a stream of helium gas. In the demonstration, there was a large helium tank on the floor with a sufficient supply for several hours of listening.
While a tank of helium, tubing, high voltage power supplies, and the smell of smoke may not be appropriate for every living room, this was absolutely the best thing I experienced at the show!
If an audio system is composed of multiple components, we may have detailed specifications for each component, but we
will not know the performance of the combined system without doing some calculations. You may have questions such as
Will my audio system produce audible noise?
Will my audio system produce audible distortion?
How will my audio components work together as a system?
How loud will my audio system play?
Use Benchmark's online audio calculators to find answers!
For example, if we know the output power of an amplifier, as well as the sensitivity and impedance of our
loudspeakers, we can calculate the maximum sound pressure level that our system can produce.
This application note provides interactive examples that help to answer the questions listed above.
