DI & Signal Processors

DI boxes and signal processors cover a broad set of jobs between an instrument and the final sound system. This collection includes direct boxes, preamps, splitters, compressors and effects processors, with options for routing, shaping and controlling a signal.

Identify the task first: converting a connection, feeding two destinations or shaping dynamics may require different equipment. Check signal levels, mono or stereo operation, power needs and output connections, then consider how the device will sit within your existing signal path.
