Portable Digital Audio SPDIF Sampling Rate Indicator 32-192kHz CS8416 DAI

Description

Portable Digital Audio SPDIF Sampling Rate Indicator 32-192kHz CS8416 DAI
This is a portable digital audio SPDIF sampling rate indicator.
This tool is very useful to know a sampling rate of digital audio signal
through a coax or optical cable.
DAI (Digital Audio Interface) IC is Cirrus Logic CS8416 (IEC-60958 compatible)
Sampling frequency range is from 32kHz to 192kHz (coax) or to 96kHz (optical).
（This tool does not detect DSD signals）
I2S output signals are available for external DAC.
Designed and handmade by a professional engineer.
Fully tested with Behringer SRC2496 and TI PCM4222EVM.
Encased in a hockey puck display case.
