Hints for Measurement of Performance
Read the Digital Audio Measurements application note (SLAA114) for an
introduction to measurements on true digital audio amplifiers.
You are welcome to use the audio precision test files available on the PurePath
Digital
™ amplifier CD-ROM. Note that an AES17 filter is required to reach the
shown measurements. Specifications for the AES17 filter are described in the
AES Standard Method For Digital Audio Engineering – Measurement of Digital
Audio Equipment (the AES17 standard is available from the Audio
Engineering Society –
www.aes.org
).
When evaluating the performance of the digital amplifier section, bypass the
digital audio processor with S320 or adjust all settings to neutral and
attenuation to 0 dB.
Connect the TAS5010−5112F2EVM to a regulated power supply with a short
cable. The length of the PSU cable must not exceed 0,3 meters.
