Test report Creative Sound Blaster Omni Surround 5.1 (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 Creative Sound Blaster Omni Surround 5.1

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".

Table

The product was tested for a long time, a method of constructing the graph and table were outdated and not suitable for direct comparison of values between different devices. The current data are the closest to "Before hard overload" as the maximum level before clipping. The latest version of the methodology uses to build on the characters of the spectra and divided into "Pure power @ class A", "Optimal power @ class AB", "Hard power @ B class" and "Before hard overload".

Now the original data to update the graph and table no. Require re-testing of the product. Re-test will be conducted only in the presence of the product in a test lab RAA.

CloseMore detailed
Reports and testing methodology is gradually updated. We try to generate the report in such a way that it would have been a single kind of report for all products, convenient for direct comparison.

We constantly introduce new tests and improving the options for displaying graphs and parameters. It introduces different changes in reports. Because reports are generated automatically, the updates do not take much time.

In the development and implementation of new tests, new reports are more complete. To update some charts and tables may require additional time to process the raw data separately for each product.

Some products require re-testing.
