Addition Studio's tracking room equipment is based on a 24 bit, 24 track, digital hard disk recording system with supported sample rates to 96 kHz. The studio utilizes both standalone and PC digital hard disk recorders with computer wave form editing programs.

The chosen front end of this system is based on time-tested analog console recording and mixing with solid state and tube preamplification, compression and processing. A variety of microphones, condenser and dynamic, are available for the appropriate applications. Four separate playback/monitoring systems are used in monitor and mixing operations.
