The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 30, our usual co-host Simon Weston has the table flipped to present his audio test and measurement computer - the ZUMI CS-A86. The ZUMI CS-A86 is a single board audio spectrum measurement instrument. The CS-A86 operates autonomously to execute advanced measurement sequences, apply for pass-fail criteria, and log all data.

The device is aimed at implementation in automated test equipment for production and development. The primary function is to obtain frequency response function measurements for DUT's that require testing of signal paths, especially involving filter structures or other signal conditioning elements. The built-in capability to configure DUT's via serial interfaces allows a comprehensive set of quality control tests to be completed without user input.

The CS-A86 provides 6 analog input channels and 2 hard wired output sense channels. All channels are sampled simultaneously at up to 100kHz with 18bit resolution. The CS-A86 package includes an LCD display based UI board for displaying measurement result.

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 25, Jorge Serrano Director of R&D at Acustica Beyma in Valencia, Spain discusses the innovation that has gone into developing the Maltcross technology for heat dissipation in Beyma professional loudspeakers

The Maltcross cooling technology that we deliver to the Professional Audio market through their speakers bring together several solutions to meet their goal; one side allows the woofer to handle bigger rates of power with a given coil diameter. This allows for Beyma to think of smaller coil designs with smaller motor structure, reducing the weight but increasing the sensitivity and also keeping an adequate power handling figure for a target application, maintaining a total SPL finally that may be equivalent to a bigger size motor structure driver.

A very interesting podcast that addresses solving key problems in pro loudspeaker design. Please LIKE, SUBSCRIBE and SHARE but most important: enjoy the podcast!

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 13, Tim Whitwell, the VP Engineering at Tectonic Audio Labs, talks to us about the balanced mode radiator (BMR) which is a unique take on the audio speaker.

Tectonic creates sound in a new way, using bending wave technology to provide an immersive sound experience that is highly tolerant of difficult environments. Tectonic loudspeakers use composite panel technology instead of the traditional cone diaphragm.

The device looks similar to other speakers from a distance but the performance is remarkably different. The BMRs create new possibilities in system design and acoustic benefits not possible with other speaker technology. Please enjoy the podcast and post your questions, comments below!

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 12, Dale Lott, CEO of Spear Labs, joins to talk about designing and building premium in-ear monitors (IEMs) in the USA

Spear Labs, which stands for Special Products for the EAR, was founded when Dale Lott was dissatisfied with the trend in high-end IEMs. The market was cramming more and more drivers into plastic shells, resulting in phase issues, raspy highs, and distortion. With a breakthrough three-stage design that harnesses the natural resonance of three rare materials, we unlocked a unique harmonious sound signature that's stunningly musical.

The materials, effort, and engineering that goes into the Spear Labs IEMs is truly remarkable. Please enjoy the podcast ;)
