The Bag End INFRA-MXB is a two-channel loudspeaker controller built for stereo 2-way systems that require a mono summed low-frequency INFRA output. It combines Bag End's INFRA dual integrator processing with frequency dividing and system protection in a compact 1U format, making it a practical choice for installations and sound systems using compatible passive Infra loudspeaker setups. Front-panel rotary controls and internally preset system parameters support straightforward deployment without adding unnecessary operational complexity.

For professional AV users, the INFRA-MXB is designed to manage low-frequency processing while maintaining dedicated stereo hi-pass outputs for the main system. Balanced XLR connectivity supports integration into standard signal chains, and the unit's analog processing architecture suits applications where precise infra bass control is needed in a rack-mounted hardware workflow. Dynamic filter overload protection adds an extra layer of operational security when running demanding low-frequency content.

This controller is intended for use with Bag End passive Infra systems and INFRA or Infrasub type loudspeakers. With programmable INFRA cutoff and hi-pass filter settings, it can be adapted within the supported ranges to suit different system tuning requirements while preserving the core operating structure of stereo input, mono low-frequency summing, and stereo high-pass distribution.
