September 26, 2025/by Pat Brown

Virtual environments for running Windows apps on a Mac are computationally intensive and complicated. For the casual user, there’s another alternative.

SynAudCon’s online training courses utilize two apps generated specifically for them. These are CAFViewer™ and IntelliKwik™. Both … Read more

Why 8 Ohms? – Part 2 – Voltage-Referenced Specifications

June 30, 2025/by Pat Brown

Despite their name, audio power amplifiers don’t amplify power. They produce a higher voltage copy of the input voltage, along with current as demanded by the load impedance.

As audio becomes increasingly digital, there remains two major design decisions rooted … Read more

Mains/Sub Alignment – A Different Take

March 21, 2025/by Pat Brown

Mains/Sub Alignment is a popular topic. Pat shares a logical, accurate, Time Domain approach that can be implemented with free software.

It’s all summed up in four instructional videos, prefaced by a short introduction video.

Loudspeaker Maximums Part 2 – Peak SPL

January 11, 2025/by Pat Brown

Finding the Maximum Linear Peak Sound Pressure Level

In the first part of this two-part series, I described how to determine a loudspeaker’s maximum continuous input voltage (MIV) regarding heat. The MIV is the maximum RMS input voltage before the … Read more

Musician’s Ear Plugs Comparison Study

December 23, 2024/by Pat Brown

Can sound be attenuated and the fidelity preserved using musician’s ear plugs?

As the population ages, hearing damage has moved to the forefront of public consciousness. Many older folks are realizing (often too late) that they had some bad listening … Read more

Why 8 Ohms? – Part 1

November 10, 2023/by Pat Brown

Anyone who has messed with audio gear of any kind has run across “8 ohms.” Where did it come from and what does it mean?

“8 ohms” is found in loudspeaker specifications, amplifier specifications, and on wire gauge charts. Amplifier’s

Line Array Realities

August 4, 2023/by Pat Brown

Line arrays are often stereotyped by how they behave at high frequencies. When full-range sound is considered, the reality is much different.

Source Types
A point source emits sound waves that are spherical in shape. The physicist’s theoretical point source … Read more
