In-Ear Monitors 101
12:00 to 1:00p
From humble roots as hearing assistance devices, today’s high-performance IEMs now rival the very best full-size headphones. Come learn all about driver types, driver complement, crossovers, timing, coherency, coupling types, how psychoacoustics can be accomplished with minimal pinnae interaction, and so much more. Join us for this fascinating journey into the past, present and future of high-fidelity in-ears — guided by the legendary pioneer of stage and audiophile IEMs, Jerry Harvey.
Instructor: Jerry Harvey, Founder, Jerry Harvey Audio
Tubes 101
2:00p to 3:00p
Ready to take the big plunge into tube amplification? Join us to discover the truths, and to dispel the myths, of tube-based audio. Learn all about triodes, tetrodes, pentodes, Nutubes, and even solid-state tubes — and how to tube roll your way to audio nirvana. Are tube buffers worth it? What’s the best way to not get ripped off buying tubes? What about current tube shortages? Whatever they may be, get all of your tube amplification questions answered here.
Instructor: Justin Weber, Founder, ampsandsound
Digital Audio 201
3:00p to 4:00p
Looking beyond the basics of digital-to-analog conversion, join us for an invaluable hour of insight into how digital interpolation filters work. This seminar will cover: understanding the importance of interpolation filtering and transients; realizing just how much time domain performance can dictate fidelity and realism, and much more. If you didn’t understand any of that, and you are currently pursuing an endgame rig with a digital source, then this is one seminar you won’t want to miss.
Instructor: Rob Watts, Digital Design Consultant, Chord Electronics
Evolution Of Hearing Simulation, And An Examination Of Frequency Response Targets And How We Use Them
4:00p to 5:00p
An examination of how the most popular hearing simulation standard (commonly referred to as “711”) was first developed well over 40 years ago — and how important advancements made in the decades since must inevitably lead to the adoption of emergent standards. Following this, an insightful discussion of frequency response targets, how they are used in the industry by reviewers, and some important considerations therein. Are we missing the target?

Special Presentation: The Role of Treble Extension In Improving Performance of In-Ear Monitors
12:00 to 1:00p
While earlier listening studies concentrated on the spectrum below 10 kHz, a significant portion of recorded music occurs as high as 20 kHz. Knowles, a leading manufacturer of balanced armature drivers and microphones for in-ear monitors (IEMs), TWS earphones, and hearing devices, conducted a new study on preferred response curves with a focus on treble performance. Join Kalyan Nadella, Senior Electro-Acoustic Engineer and BA Commercial Team Lead at Knowles, as he shares what was learned about the significance of treble response on listener preferences, and how that led to the development of Knowles’ new balanced armature Supertweeter.
Special Guest: Kalyan Nadella, Knowles Corporation
Special Presentation: Solid-State Fidelity - An Introduction to the World’s First All-Silicon µSpeakers for Personal Audio Devices
2:00p to 3:00p
This talk will introduce a new, all-silicon transduction mechanism that is set to disrupt century-old coil/magnet driver architectures. This new, solid-state architecture implements both actuation and diaphragm in silicon resulting in unmatched part-to-part frequency response and phase consistency. This innovative transduction mechanism has also produced the world’s fastest and most precise µspeakers, eliminating spring and suspension recovery of coil speakers which improves audio quality and sound field reproduction.
Special Guest: Michael Ricci, Sr. Director Electroacoustic Engineering from xMEMS Labs, Inc.
Special Presentation: Chord Electronics’ Mojo 2
3:00p to 4:00p
Seven years after the debut of its predecessor, Chord’s long-awaited Mojo 2 portable DAC/amp is finally here. Come join Rob Watts of Chord Electronics for a fascinating recounting of its development over the years, and a comprehensive overview of the Mojo 2’s groundbreaking features, including: UHD DSP (a fully transparent and lossless digital tone control); enhanced menu options featuring an additional control sphere for crossfeed/mute/lock settings; intelligent FPGA-based battery management and charging; and of course more taps.
Special Guest: Rob Watts, Digital Design Consultant, Chord Electronics
Hopefully the seminars would be filmed and uploaded on YouTube. The sessions by JH, Chord, and Knowles touch some very interesting topics. I feel jealous of folks who can be there.
@JAnonymous5150 you need to share some notes after the event, mate
