About this report
This is a report for professionals with a suite of tests for line output devices. Alternative version of the report for "dummies" in development.

A suite of tests for the line-out can be used for headphone or speaker output if in this mode it is possible to use the device as a source for connecting an external amplifier or if such a test suite can give more information about the implementation of the DAC in the device.

Line-out, differences from the output for headphones and speakers

More detailed

Measurements of Aful SnowyNight Single-Ended were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Aful SnowyNight Single-Ended test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.
