ENIGMA 26i is a complete integrated tool that allows flexibility and processing for live and install sound system applications.



ENIGMA 26i is a cost-effective 2-IN/6-OUT digital speaker management system. Designed to be catered for any crossover configuration, it provides the suitable processing and control for live application use. It offers 2 analog inputs, and 6 analog outputs, managed by a powerful DSP Engine, in addition to 24 Bit AD/DA Converters. Each input channel provides a choice of EQ with a 31-band Parametric EQ, gain control, noise gate function, RMS Compressor, Internal White/Pink Noise Generator and configurable delay. Each output offers up to 7-band of parametric equalization into the crossover filters which themselves provide slopes from 6dB/Octave up to 48dB/Octave. Each output path also features peak limiter and driver alignment delay.


The ENIGMA 26i supports a full matrix mixing mode where inputs may be routed/mixed in any ratio to any output. For remote configuration and control the ENIGMA 26i can be connected via USB or RS485 connections. The control remote PC software allows simultaneous control up to 32 units, setting all parameters and showing real time levels.
