The Lark 150 supports three record modes. Below is a brief explanation of the difference between the Three.
The volume from the Transmitters:
Mono mode: Signals are recorded and playback using a single audio channel.
Stereo Mode: Sounds are recorded and playback using two audio channels:
Left and Right.
Safety Track Mode: Sounds are recorded and playback using one channel (same as Mono Mode).
The 2nd track is designed for backup (-6 dB lower than the 1st track).
After upgrading to V22.214.171.124 added Phone Mode for optimal mobile phone audio recording experience.
The audio output gain will be changed to 13 automatically after you select this mode. Meanwhile the function of HPF will be activated (Minus 75Hz)
