Music Tribe
- Innovation Acoustics Leader
2018 - 2019
Over the years, MUSIC Tribe has become one of the world’s largest company for pro audio and high-tech music products, including brands such as Behringer, Midas, Klark Teknik, Turbosound, Tannoy, TC Helicon, Lab Gruppen…
As head of acoustics in the China base site, I was a key interface between the loudspeaker brands and the R&D team for product definition, development, evaluation and validation.
I was highly involved in providing technical guidance and supporting various departments such as:
• Production engineering and manufacturing for improving processes, assembly jigs and record of best practice
• Quality department for improving quality control.
• Procurement for introducing new suppliers.
• Transfer of cone paper manufacturing in-house.
Under my dynamic leadership, my team started to follow streamlined workflow and use upgraded best practice guidelines in order to fit in the new systems being implemented across the whole company.
I prepared the team roadmap and applied for new software/equipment for the team to fulfill its goal of designing state of the art transdcucers and speaker systems, right first time, on target, on time and at the right cost.

- Assistant Manager
2009 - 2009
I have been in charge of setting up the Evaluation Team in charge of the eveluation of loudspeaker systems at all stage of the development.
Below are some of the key functions I fulfilled:
• Defined and started to set up this new team (Organization, workflows, handbook, recruitment, definition and implementation of measurements methods and standards).
• Evaluated loudspeaker systems at all stages of development (including vented loudspeaker systems alignment, crossover).
• Defined design modifications for improving loudspeaker system when necessary.
• Approved loudspeakers systems’ design.
• Defined and implement quality control test procedures for systems on production.
• Provided technical support and guidance for the resolution of various interdepartmental issues.
I have tuned loudspeaker systems (speakers and amplifier) such as B1030A (available), B1031A, B1800D-PRO (*), B1500D-PRO (*), still under development at that time.
(*) Early development stage.
