# Gain Control for Analog Voice Modules Overview

You can control the gain on analog voice modules in both the analog-to-digital and the digital-to-analog directions. The Rx direction corresponds to the analog-to-digital direction, and the Tx direction corresponds to the digital-to-analog direction. Table 1 shows the minimum and maximum gain for each direction and the granularity for the module.
