Product configuration description

1）Version：Firmware Version of module 1.2 2）Channel：1-16channel can be chose The channel that configures SA316 needs external power supply. Each frequency band is divided into 16 channels, with a difference of 1MHzbetween adjacent channels. The specific corresponding frequencies are shown inthetable below：

3）Output Power: 0-10dBm ; default: 10dBm 4）Input Source: MIC or IIS; default: MIC 5）Format: when use IIS , you can choose High Bits or Low Bits 6）Net ID: you can set ID of each module 7）Volume: high low of voice, default: 37% 8）Signal Strength Threshold: Sound volume preset value. When the emitted soundis larger than this value, it can be emitted. the smaller the more sensitive

1）Version: Firmware Version of module 1.4 2）Channel: 1-16channel can be chose The channel that configures SA316 needs external power supply. Each frequency band is divided into 16 channels, with a difference of 1MHzbetween adjacent channels. The specific corresponding frequencies are shown inthetable below：

3 ） Anti-Howl: There will be noise when the microphone and speaker are closetogether.Default OFF.。 4）Input Source: MIC or IIS; default：MIC 5）Format: when use IIS , you can choose High Bits or Low Bits 6）Net_ID: you can set ID of each module 7）Power_Saving: power saving mode, default：off 8）Volume: high low of voice, default: 77% 9）Signal Strength Threshold: Sound volume preset value. When the emitted soundis larger than this value, it can be played. The smaller the more sensitive
