Rarely used, everything is in perfect working condition.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.The compact mixer features 3 transformer balanced microphone or line level switchable inputs via XLR female 3-pin connectors.The 302's headphone monitor out is capable of varying output impedance between 8 to 1000 ohms. The monitor source is capable of individual channel, mono, stereo, M-S to stereo monitoring and more.
Each input and stereo outputs provide input and output limiting that prevents signal overload, eliminating noise and distortion.
Channels 1 & 2 are stereo linkable, channel 2 features a polarity (phase) reverse switch. This makes the 302 ideal for decoding M-S stereo captured audio signal.
The unit is capable of powering condenser microphones requiring +48V, +12V and +12V-T phantom power. Phantom power is individually switched for every channel.A low-cut filter switch is available on every input, removing noise and rumble below 80Hz.
