When the GAIN is set to 0, the gain is 0 DB. This is equivalent to a pure potentiometer. When the GAIN is set to greater than 1, it can be used as a preamp, with a gain of 3-21 DB. There is no need to set it too high, otherwise the signal will be too strong and cause the rear stage to saturate. It is better to set it within 12 DB.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003eThere are two methods to set the GAIN.
