"Singing the song of our people"
Posted: Sat Dec 02, 2017 6:06 pm
This came up in another thread and I thought it might have some value here as a separate post...
Although 700 and 1900Hz are the "standard" for official two-tone IMD performance tests, it is by no means necessary or required that to use those tones specifically. I set my two-tone test to run 70 and 190Hz. This provides more than sufficient stimulus for PureSignal to get a solution and to test both PureSignal performance and drive settings on the amp before starting operations.
70 and 190Hz is also quite a bit more pleasant to listen to. That combination does not "sing the song of our people" and immediately mark one as a crazy Apache Labs radio owner
