The BerryBak BDSP2.4U MAX is a digital active crossover with an asymmetrical 2-input / 4-output architecture, designed to perform two-way filtering in an audio system. Its line outputs connect directly to the amplifiers dedicated to the tweeters and woofers, thereby replacing the passive crossover located between the amplifier and the loudspeakers. This configuration avoids the electrical losses and phase shifts associated with passive components, while allowing the level and crossover frequency of each output to be adjusted independently.
The crossover points are set using the front-panel potentiometers, with no programming required for everyday use. The DSP allows real-time adjustments, which makes it easier to adapt the filtering to the loudspeakers and listening preferences; a customization of the SigmaStudio range can also be requested. With its four outputs, the BDSP2.4U MAX is particularly suited to configuring most 2.1 and 2.2 systems.


Signal processing relies on the ADAU1452, PCM1822 and PCM5122 circuits, powered by an architecture designed to limit interference. The capacitors stabilize operation, while the common-mode chokes attenuate interference and the isolated power supplies reduce noise related to ground loops. Isolation circuits complete this arrangement in order to preserve signal integrity within the setup.
Its compact matte anodized aluminum enclosure limits the footprint on a desk or in a rack, while protecting the circuits for integration into a home system or a DIY speaker. The RCA connectors handle the audio links, power is supplied via USB Type-C and an ICP port allows programming. Setting up the connections thus remains straightforward, while the front-panel crossover settings make it possible to bring an active system into service without any prior software configuration.
