hey all.
If anyone is interested in playing with the RX and TX equalization settings
for the TS570G series, here is the website
www11.cds.ne.jp/~torii/eng1.htm
The Software is accessible if you play around with cursors a bit.
I chose sample filter and there is a flat response setting which will allow
you to use an external equalizer or specially designed mike with better
results then with the preset filters.
You can also get the ts570 control software from this website.
