Clockwise rotation reduces low frequency gain. Clockwise rotation increases automatic low frequency attenuation.
Clockwise rotation reduces high frequency gain.
Clockwise rotation lowers compression threshold, which reduces SSPL90 and gain at high input levels. Clockwise rotation lowers compression threshold, which increases gain for soft, high frequency sounds. Clockwise rotation reduces low frequency gain. Clockwise rotation reduces low frequency gain. Clockwise rotation reduces high frequency gain.
