Amperes Dual Output Pre Amplifier Mixer- MX2322

Dual Output Pre Amplifier Mixer


MX2322 is a rack mounted pre-amplifier mixer, suitable not only for PA installations, but also for audio mixing at conference room, function halls etc.  It has 12 inputs for mic / line audio as well as a dedicated jack for paging mic, which would mute other channels when paging is active. Each input can be assigned to either Ch A or Ch B out with its individual 3 band tone controls, which is essential to deliver different set of tones to different target areas for broadcast.

Most connections has been made easier with its Phoenix mini connectors, which is largely preferred type of connections in fixed installations.

MX2322 is a preferred choice for various PA installations and other relevant applications due to its various features, flexibility and easy to use design.

Application Example

The schematic below shows an application for partitioned hall 1 and 2, such as in function halls, exam halls etc.  Other similar applications are :

- Mosques : which may separate prayer hall and minaret speakers to enable tone controls

- Restaurants : to segregate audio to kitchen and dining areas

- Retails outlets : providing different music to different sections

- Uninterrupted paging systems
