Warm Audio Bus-Comp – Stereo VCA Bus Compressor

The Warm Audio Bus-Comp brings the classic sound of large-format console bus compressors into a modern studio-friendly design.

Key Features

• Stereo VCA compression: Provides the tight, responsive character associated with classic analog mix-bus compression.
• Selectable CineMag USA input/output transformers: Engage added warmth and harmonic richness or bypass for a cleaner, more transparent signal.
• Side-chain high-pass filter: Choose from 30, 60, 105, 125 or 185 Hz to prevent low-end frequencies from over-triggering the compressor.
• Flexible attack, release and ratio controls: Allows fine-tuning from subtle glue to more aggressive, punchy compression.
• Balanced XLR and TRS I/O with external side-chain input: Easy integration into studio or hybrid setups with routing options for creative dynamics processing.

Customer Benefits
