PROFESSIONAL AUTOMATIC MIXERS
AMA 3150 – AMA 3250 – AM 3000 – AM 3008
PRODUCT DESCRIPTION
Automatic mixer considerably improves the audio quality in all that applications of voice survey in
which more microphones are used. Softening microphones when they are not in use, an automatic
mixer helps to minimize background noise and reverberation, supplying a clearer and more
intelligible audio.
The mixer only starts relevant microphones in just 4 thousandths of a second.
Moreover, there is no need of specific microphones: mixer works with any kind of microphone or
professional radio microphone. XLR connectors make microphone connection quick and simple.
The starting threshold is automatically.
These features guarantee that the undesired background noise would be at minimum and that the
speaker voice instantly starts one microphone only.
When more than 8 microphones are necessary the Automatic Mixer Expansion AM 3008 is used.
It is connected to amplified mixer and mixer’s connector (LINK IN) by the special cable supplied
with the equipment (Patch cord CAT 5 FTP 8 pin whit TJ45).
The Expansion has 8 electronically balanced micro phonics inputs.
With the possibility to connect up to 2 expansions in cascade, could have a max of 24 micro
phonics inputs available.
This unit is therefore the extension of AMA 3150, AMA 3250 and AM 3000 units of which it
maintains the main features, advanced functions and possibility of internal modifies. (see under
Main Features and Installation)
