+ | A couple of disclaimers starting by a general statement: | ||
+ | Measurements are done as close as possible to what would be a scientific measurement process (Configuration and tests are documented, are reproducible by a third party, tests results are published, known assumptions and limitations are mentioned as far as possible). | ||
+ | |||
+ | Also: | ||
+ | |||
+ | * **Statement #1** : Measurements are done in recording studio environment. Namely, there is no control on CEM/EMI interfering with measurements apart from standard studio installation best practices in terms of proper ED grounding and shielding. | ||
+ | * As a consequence, | ||
+ | * **Statement #2** : One input and one output are used on each unit, there is only one interface sample. Statistically processing those measurement among several units/ | ||
+ | * As a consequence, | ||
+ | * **Statement #3** : XR18 has two high impedance instrument inputs which MR18 does not have. For the sake of comparing apples with apples, Input 9/10 and Output 1/2 are used as references on both units | ||
