External Mute Input
The External Mute Input provides the possibility to mute the NTi Audio TalkBox from
a remote position, such as by using a mobile phone or radio control devices. Clos-
ing an external switch connected with this 3.5mm jack connector (connecting dip &
ring) will mute the audio signal equally to the output selector switch in mute posi-
tion. This feature is of great help e.g. at STIPA measurements in large buildings.
Power Supply
The TalkBox handles an input voltage range of 10-18 VDC. An external power supply
(for worldwide operation) is supplied as standard. The wide input voltage range al-
lows the operation even from a battery pack.
