What Role Does the S-1 Processor Play?

The Meyer Sound S-1 is the system controller and crossover unit designed to match the MSL-2A’s driver response. It delivers crossover filtering, phase alignment, EQ, and driver protection, ensuring that each component works in harmony.

Features of the S-1 Include:

• Balanced XLR inputs/outputs

• Fixed crossover points for bi-amp systems

• Peak limiting for transducer protection

• Simple, analog interface

• Rackmount design

Because it’s specifically tuned for the MSL-2A and Meyer subs like the USW-1 or 650-P, the S-1 remains a critical part of this analog signal chain.
