An increase of the input level leads to more intensive compression. When mastering full scale material, the reduction can be useful. The output is used to adjust the level ratios of input and output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eATTACK \u0026amp; RELEASE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe time parameters Attack and Release are switchable in six steps from Slow to Fast.
