The Punch Factory takes Aphex"s legendary optical technology normally only found in expensive rack-mounted studio gear put at your feet and into your live performance. It"s truly the most transparent, uncolored compression you can find at any price. * Punch Factory levels out volume peaks and dips, maintaining a consistent level within your mix. Quiet passages no longer get lost, and louder passages don"t overpower without pumping, "breathing" artifacts commonly found in most compressor pedals. * The new Punch Factory has something that most other optical compressors don"t have is a Ratio Control. This allows changing the amount of compression without overtly affecting the level.
