Bag End INFRA-MX2

The Bag End INFRA-MX2 system module is a two channel loudspeaker controller. It is designed for either stereo 2-way operation with a mono sum INFRA low frequency output or mono 3-way operation. The INFRA-MX2 incorporates the INFRA dual integrator, frequency dividing, and system protection in an easily operated configuration where the system parameters are internally preset or available on front panel rotary controls.
