Product Description
The Clockaudio AM81 is an 8 channel automatic microphone mixer ideal for multi channel microphone systems in conference and voice reinforcement applications.
By automatically sensing when a channel becomes active the AM81 will simply control the level of the system dependant on the priority settings, the NOMA (Number of Open Microphones Attenuated) function will also control and adjust the mixer output to prevent feedback due to open microphone channels.
Expansion easily achieved with up to 15 units able to be cascaded for medium to large system applications (120 microphones maximum).
