Audio Signal Processors

About Signal Processors

Signal processors are essential tools for shaping, managing, and refining audio signals in both live sound and studio environments. They help control tone, dynamics, and clarity—making them a vital part of any professional or home audio setup.

Common types of signal processors include:

• Graphic and parametric EQs – Adjust frequency response to balance mixes, correct room acoustics, or tailor the tone of vocals and instruments.
• Compressors and limiters – Control dynamic range to ensure consistency and prevent signal peaks from overloading your system.
• Noise gates – Remove background hiss and unwanted low-level noise, commonly used on drum mics, vocals, and guitars.
• Crossovers – Split audio into high, mid, and low-frequency bands for more efficient routing to subwoofers and speaker arrays.
• Hum eliminators – Solve common ground loop issues and unwanted interference, particularly in larger or complex audio setups.

These processors are typically rackmounted but are also found in standalone or portable formats. They’re used by sound engineers, musicians, venue operators, and educators to improve clarity and control across different environments.

At SWAMP, we stock a reliable selection of signal processors from trusted brands like Alctron and ART, suitable for live stages, rehearsal rooms, studios, and installed audio systems.

Whether you're tightening a mix, improving system protection, or solving noise problems, these tools give you precise control over your sound.
