I want to know the answer to the following question:
What was the industry standard in Europe for record equalization?
All the background I'm provided with is that "In the US there were more varied practices and a tendency to use higher bass turnover frequencies such as 500 Hz as well as a greater treble rolloff like −8.5 dB and even more to record generally higher modulation levels on the record.". Is that enough to answer the question?
