Training Session Details
Saturday, May 4, 16:00 — 17:00 (Sala Manzoni)
PT2 - Intelligent Compression in the Analog Domain
Utilizing a unique control circuit, a totally new approach to AGC, and entirely discrete electronics, the CharterOak SCL-1 provides completely artifact free compression. The device achieves this through waveform differentiation and integration. The SCL-1 employs a rectifier circuit, that has a parabolic average charge curve. The intent of the circuit is to provide fast releases of rhythmic and staccato peaks, and longer releases of legato notes, within the user established range of dynamic compression, which release to a continually changing average level or sustained music, which is determined by the parabolic charge curve of the storage capacitors.
Saturday, May 4, 17:00 — 19:00 (Sala Manzoni)
PT1 - The Use of Analog Gear in the Digital EraPresenter:
The history of PMI Audio Group and connected brands. Why we do what we do: a tour about the technical/philosophical differences that makes our brands special and what it is that we do differently from other companies.
Sunday, May 5, 17:30 — 18:30 (Sala Foscolo)
PT3 - Wide Bandwidth Equalization in the Analog Domain
Based on research related to the sensitivity of our ears throughout the full bandwidth of our hearing, the CharterOak PEQ-1 provides extremely musical equalization in a stereo tone control of unparalleled musicality. Utilizing a unique circuit, and power distribution, along with a unique configuration with respect to bandwidth and cut and boost around the center frequency choices, the PEQ-1 achieves extremely powerful and musical equalization with
minimal phase shift at the high frequencies, and extremely high headroom and low distortion.
Monday, May 6, 16:30 — 18:30 (Sala Alighieri)
PT4 - Recording and Mixing with Universal Audio
Record/Mix with Universal
An overview is given of Universal Audio history from the 1950s to present, detailing various well-known analog gear and hints on how and why you would, and should use them.
Wesley Bendall will talk about the benefits that UA plugins can bring to a recording and a mix, and will explain and demonstrate the Apollo platform, especially new Apollo 16.
Tuesday, May 7, 10:30 — 12:30 (Sala Manzoni)
PT5 - Audio Design Workshop Live—Part 1Presenters:
Peter Larsen, LOUDSOFT
John Richards, Oxford Digital
10:00 - 10:30 Registration
10:30 - 11:30 Designing Transducers for Compact Active Speakers, Peter Larsen, LOUDSOFT
The LOUDSOFT FINE software suite for Loudspeaker Design and Test & Measurement is a circle of design tools, where each component supports the other. With these powerful FINE programs you can design all parts of the speaker system. The FINE R+D analysis/measurement system and the FINE QC control system supplement the design software. The Rub & Buzz function is the best on the market finding 100% failures of both active USB speakers and micro speakers. These tools are rapid and effective in modern transducer and speaker system development and the simulations very closely matches measurements of the devices when built.
11:30 - 12:30 Optimizing Compact Loudspeaker Performance—The Role of DSP, John Richards, Oxford Digital
The form factor of all consumer devices from cell phones to flat panel TVs is shrinking and often the design is under the control of a stylist rather than anyone who understands acoustics. This, together with pressure on the Bill of Materials cost and increasing customer expectations, creates real challenges in obtaining good, differentiating audio quality in the product. DSP can mitigate many of the inherent deficiencies present. The tutorial shows how a combination of an integrated suite of audio effects together with automated frequency correction can be used to radically improve sound quality whilst providing rapid time to market.

PT6 - Audio Design Workshop Live—Part 2Presenters:
Anthony Waldron, Audio EMC
Simon Wollard, Prism Sound
13:30 - 14:30 Audio Power Amplifiers; EMC Best Practice Revealed, Anthony Waldron, Audio EMC
The performance of analog and (now) digital audio systems is approaching an all time high—yet we still suffer bad bouts of noise, distortion, and interference on a regular basis. The physical reasons for poor audio performance is provided, along with practical solutions for designing audio amplifiers and systems to maximize signal integrity and be immune to noise and interference.
14:30 - 15:30 Audio System Analysis—Tips and Tricks to Verify Your Designs, Simon Wollard, Prism Sound
Active loudspeakers are becoming ever more complex in terms of their underlying architecture. The number of input interfaces has grown significantly in recent years; sophisticated signal processors have evolved to greatly enhance performance; amplifiers have grown more capable in terms of self-protection, output power and efficiency; transducers are ever-improving in terms of smoother response and lower distortion. This practical discussion will teach the audience how to take advantage of modern digital audio analysis techniques to provide far greater and more rapid insight into the performance of active loudspeakers than was previously possible with classical audio measurement techniques.
