NEXO NX242 TDcontroller

NEXO NX242 TDcontroller is an advanced, proprietary digital processor that maintains exceptional performance and reliability in GEO, Alpha and PS loudspeaker systems and associated Sub-basses.

NEXO NX242 TDcontroller

The NX242 provides crossover, sensed-amplifier control and system alignment acoustically matched to each NEXO component.

The NX242's complex software algorithms integrate this calibrated data with sensed-voltage measurements,while analogue I/O functions share rear panel space with digital Audio Distribution and System Control over Standard Ethernet via EtherSoundTM connection using the NXtension-ES4 Expander Board.
