Audio Input/Output Terminals (VB-H41 / vb-M40)
Each audio input/output terminal has one input system and one output system.
Connecting the camera to an audio input/output device such as a microphone or a speaker with an amplifier allows you to send/receive audio through the viewer.
Audio Input Dual LINE IN/MIC IN (monaural input)
Although the camera has a single audio input system, it supports two types of microphone input:
LINE IN and MIC IN. Before using the audio input, change [Audio Input] on the Setting Page (see Ô?peration GuideÔ > Ô?udio InputÔ©. LINE IN is selected by default.
Input terminal: 3.5 mm ( 0.14 in.) mini jack (monaural)

* Use a microphone with an amplifier.
Audio Output Terminal LINE OUT (monaural output)
Connect the camera to a speaker with an amplifier. Audio can be sent to the speaker from Viewer.
Output terminal: 3.5 mm ( 0.14 in.) mini jack (monaural)
Output level: up to 1 Vp-p
* Use a speaker with an amplifier.
