OVERVIEW
The Sonosax SX-PR series portable stereo audio mixers are designed for jobs where
compactness, portability and extremely high quality are required, such as remote
classical music recording and location film and video sound work. The controls and
features have been kept simple, yet complete enough for getting the job done well.
The mixers consist of a master module and one (SX-PR2), two (SX-PR4) or three (SX-
PR6) dual mic/line input modules. Input modules may be easily added or deleted. These
modules can be positioned in any order, such as the master module on the left and
inputs on the right, or vice versa. Even a master module flanked by input modules is
possible.

standard. RF filters are optional.

repeatability and precise channel matching.
• Overload LED for each input flashes 6 dB before input amplifier clipping.
