According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in
hearing loss. When using equipment capable of generating high SPL, use hearing protection while such
equipment is under operation.

INTRODUCTION
Thanks for purchasing the Alto Professional ACOM2 Compressor/Limiter/Gate! ACOM2 is a powerful
dynamic processor with several innovative circuit designs that make it a versatile product: smart and fast

• Couple switch for a one-touch selection between two mono channels or stereo-linked operation
• Sidechain send and return for use in an external effects loop
• Switchable low-cut filter minimizes audio-program pumping triggered by kick drum
