A very compact, professional PA mixing amplifierPrevious page


The BMA is the most easy and universal 100 volt professional mixing amplifier for commercial and industrial applications. This amplifier is very intuitive to use because it has only the buttons available you really need.

4 microphone inputs with integrated speech filters, 4 selectable line inputs and one emergency line / telephone input are available where MIC input 1 is meant to be the main microphone paging input. The BMA allows you to have priority with your paging microphone as well as a seamless mix of your microphone with your sound source.

BMA has a 3-level priority system where the emergency line / telephone input at the back have the highest priority. MIC1 has the second priority level and the third priority level can be activated by a dry contact at the back of the amplifier that mutes.
