Prism Sound & Power Physics Present - How to Choose & Test Audio Power Amplifiers

November 28 2014, 04:00
The webinar “How to Choose & Test Audio Power Amplifiers” will be offered on Wed, Dec 10, 2014 at two different hours on that day. Registrations are open.

Promoted by audio test and measurement specialist Prism Sound (from Cambridgeshire, England) and audio electronics specialist Power Physics (from Newport Beach, California) this webinar is part of the Wednesday Webinars series, regularly produced by Prism Sound, covering a range of technical issues surrounding audio test and measurement.

During the 137th AES Convention in Los Angeles, PowerPhysics founder Gordon Wanlass did a presentation on “Selecting Amplifiers and Power Supplies for Audio Systems,” explaining simple measurements and calculations required to make sure audio product works well and keep working. For the purpose of the presentation, Gordon Wanlass used a Prism Sound dScope Series III audio test solution integrated with PowerPhysics’ test software using NI LabView.

Following the same concept - part of the Product Design Track at the AES Convention - the two companies decided to promote a webinar accessible to anyone, exploring PowerPhysics’ test software on NI LabView to control the PrismSound dScope Series III for amplifier test applications.

The focus of the webinar consists on explaining how to select a power supply or amplifier for OEM speaker design using basic measurements and simple calculations. Gordon Wanlass will also explain how to evaluate the ever increasing supply of off the shelf audio electronics and select the right power supply or amplifier for any powered speaker design.

Founded in 1987 in Cambridge, UK, Prism Sound manufactures a range of high quality professional test equipment for analogue and digital audio applications. The dScope Series III platform has established itself as the instrument of choice for many of the world’s leading manufacturers and designers of professional audio equipment, from surround sound microphones to multi-channel consoles, USB & Firewire audio interfaces, PA loudspeaker systems and much more.

Amongst many innovations, Prism Sound invented a test signal known as the ‘JTest’ for evaluating the performance of digital AES receivers and DACs in the presence of data jitter. This test method has now been adopted as an industry standard in the audio test and measurement market, and remains one of the many vital components in the audio engineer’s toolbox for design, evaluation and installation purposes. 

For design engineers, dScope’s Smart FFT detectors provide unique insight into the spectral make-up of noise and distortion products, well beyond simple THD+N measurements, giving instant feedback on the real-world performance of products.
