Whirlwind’s QBOX-AES

A multipurpose testing device for troubleshooting digital AES-3, S/PDIF, and analog audio signals, the QBOX-AES comes loaded with a variety of useful features and testing operations. You can easily switch between Analog or AES testing operation and an AES Function switch determines how the AES testing occurs. Monitor your AES stream in real-time, check the AES stream’s sample rate, and convert analog signals (MP3 player/smartphone/etc.) into an AES stream—and vice versa, and much more. It includes many of the features of Whirlwind’s QBOX built-in to deal with audio issues you come across. Powered by four AA batteries or included wall power supply.
