The Sound Devices 302 is a professional, compact 3 channel audio mixer designed to meet the demands of professional film, ENG / EFP and broadcast applications. Its compact design, extensive feature set and superior audio quality justify the mixer's popularity among industry professionals. The 302 features 3 balanced XLR inputs that are capable of accepting mic or line-level signal (user switchable). The output stage features stereo (L/R) balanced XLR outputs that are also mic or line level switchable (factory set to line, refer to manual for mic level set up).
A user friendly control panel is accessible at the top of the unit for easy set up of additional functions or signal routing. Each channel provides individually switchable +48V, +12V and +12V-T phantom power for condenser microphones. Channels 1 and 2 are stereo linkable and a polarity (phase) reverse switch is provided on channel 2. This makes the 302 ideal for M-S stereo style capturing and monitoring. Input and output limiters are user switchable and eliminate noise and distortion caused by signal overload. Low-cut filter switches eliminate noise below 80Hz and the unit is powered by 3 AA batteries or external 5 - 18VDC power source.
