Test report Gigabyte GA-A75-UD4H: Realtek ALC889A (report for a pro)



About this report

This is a report for professionals with a suite of test of headphone amplifier.

You can see a simple report for "dummies" with explanations of the main characteristics for Gigabyte GA-A75-UD4H Realtek ALC889A

One product can have multiple reports in different modes and with different a suite of tests.

A suite of tests for a headphone amplifier can be applied to just a universal output without a formal presence of an amplifier, if in this mode you can connect headphones to this output. Based on the results of the tests, you can understand the real picture, is the output powerful enough or not, with the initial data on the circuitry as a "black box".
