VOX400 - Quick Start Guide
The VOX400 is a voice annunciator and MP3
player with built in amplifier and speaker. It
can be triggered by using hard-wired alarm
inputs, via RS485 or RJ45 Ethernet from other
electronic equipment such as a computer or a
DVR / NVR.
The MK4 also has a new LAN Trigger feature
which means MP3 files can be triggered on a
local network, via a additional software, see
the full manual for more information.

Powering the VoiceOFF
Power the VOX400 from 12V DC (via the input voltage terminals) on the PCB. The current
consumption is 200mA maximum. A power supply is not provided.
Line input Connection
The line input audio is connected to the yellow audio input phono (RCA) connector on
the PCB. The line input can be taken from an audio device or DVR via a audio phono
(RCA) lead.
Volume Control
Use a small precision screwdriver to carefully adjust the pots.
It is a is multi-turn pot (20 turns from minimum to maximum)
this means that in order to make a noticeable change the
screw will need to be turned multiple revolutions. When you
receive the VoiceOFF unit, the volume levels will have already
been adjusted to a mid way point to suit most applications.
Increase - Turn clockwise
Decrease - Turn anti-clockwise
Triggering the Pre-recorded messages
The VoiceOFF will play a message depending on which alarm
input is triggered and by how the MP3 files are named.
For example, when alarm input 1 is triggered, the VoiceOFF looks
for an MP3 file that been named 0001.mp3.
See overleaf for the Pre-recorded message table.
If the alarm input trigger is continuously activated the audio
message will repeat. Once the trigger is released it will continue
playing the message in its entirety.
