Am8 lectrosonics, inc. 2 introduction the am8 automatic microphone mixer is an 8 chan- nel, single rack space audio mixer. Using lectrosonics’ unique adaptive level proportional mixing algorithm, the automatic action is inaudible and simple to set up. The am8 offers remote control of all channel lev...
