Sound Devices 302 Compact Production Field Analog Mixer Overview:The Sound Devices 302 is the most compact and cost-effective, battery-powered, professional audio mixer in its class. This no-nonsense, rugged little mixer features three exceptionally quiet mic preamps and balanced transformers to perfectly handle very low frequencies.With important features to accommodate nearly any over-the-shoulder production, the 302 interfaces with wireless transmitters and receivers, camera audio inputs of all kinds, and external audio recorders. Its microphone inputs share the same superb circuitry as the 552 Portable Production Mixer and MixPre-D Compact Field Mixer.Like Sound Devices larger 552 Field Mixer, the 302 is a complete Field Mixer, but designed in a super-compact package. Controls are accessible on its three main surfaces, its high-efficiency power circuitry runs the mixer from either three internal AA batteries or external 5-18 VDC.Superb Audio with Flexible ControlDeveloped specifically for audio-for-picture applications, the 302 mixer is the perfect tool for production companies and camera operators wanting to take control of their audio. The 302 is stunning for its size, flexibility, control and performance; it is the most widely-used compact battery-powered professional audio mixer in its class.Reliable and Consistent PerformanceWith a complete feature-set like super-bright LED displays, excellent internal limiters and high-pass filter, the 302 can accommodate nearly any over-the-shoulder production and perform reliably regardless of field conditions. It effortlessly interfaces with wireless transmitters and receivers, camera audio inputs of all kinds, and external audio recorders. With high-efficiency power circuitry that runs the mixer from either three internal AA batteries or external 5-18 VDC.Specifications:Frequency Response:20 Hz – 30 kHz, +0.2, -0.5 dB, -1 dB @ 5 Hz and 50 kHz typicalEquivalent Input Noise:-126 dBu (-128 dBV) maximum (22 Hz – 22 kHz bandwidth, flat filter, trim control fully up)Input Clipping Level:0 dBu minimum (trim control fully down)Line Output Clipping Level (1% THD):20 dBu minimum, 18 dBu minimum with 600 ohm loadDynamic Range:115 dB minimum (trim fully down)THD + Noise:0.007% typical (1 kHz, +4 dBu at Line out), 0.009 max (50 Hz to 20 kHz, +18 dBu at line out, fader fully up)Output Noise-100 dBu (-102 dBV) maximum (22 Hz – 22 kHz bandwidth, flat filter, master gain fully up, faders fully down)L/R Gain Matching:+/- 0.1 dB (Mic In to Line Out)Metering:40-segment, sunlight-viewable Selectable peak, VU, or peak (with or without peak hold) + VU ballisticsHigh-Pass Filters:Switchable 80 Hz or 160 Hz, 12 dB/oct, silent activationMic Powering (each mic selectable):None, 12 V phantom, 48 V phantom, 12 V T-power, selected per mic inputInput Limiters:+18 dBu threshold, 20:1 limiting ratio, 1 mS attack time, 200 mS release time.Output Limiters:Affects the outputs of the mixer.
