Frequently asked questions
Can either unit work for live sound reinforcement?
Yes, but differently. The 234s excels at speaker array crossover management in live sound. The 640 is better suited for larger live sound systems requiring paging integration, zone control, and comprehensive input/output processing.
Which is better for a small studio or home setup?
The 234s is the better fit—it provides clean crossover functionality for studio monitoring or small speaker systems at a lower price. The 640 is designed for commercial installations and includes features unnecessary for home use.
What's the main technical difference in filtering?
The 234s uses Linkwitz-Riley 24dB/octave filters with a 40 Hz low-cut option, focused solely on frequency separation. The 640 includes crossover filters as one tool among many DSP functions like EQ, limiting, delay, and feedback suppression across its 6 inputs and 4 outputs.
Which handles more complex audio routing?
The 640 is designed for complex routing with primary source selection, source ducking for paging, and priority override across 6 inputs and 4 outputs. The 234s is a simpler crossover with dual-channel architecture for speaker system frequency splitting only.
