Disclaimer: This device was included in James' surprising shipment from Austria
I spent some time to calibrate my measurement setup for analyzing line level devices. Was going to do it sooner or later, but never really had an urgent need for it until now. No technical detail of this device has been disclosed by the manufacturer, Creative, which is quite shameful.
Mark of the Unicorn UltraLite-mk3 has been used for the analysis, and the device's output level is set to maximum. Please refer to AES17-1998 standard for further details on the analysis parameters.
