Overview:
Developed specifically for audio-for-picture applications, the SOUND DEVICES 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.
The 302 received DV Magazine's Award of Excellence
Features:
1.) Fader Primary control for adjusting the input level during operation.
2.) Peak LED - When illuminated, indicates that the channel level is approaching the clipping point.
3.) Limiter LED - When illuminated, indicates that the channel limiter is active and is reducing the channel gain to prevent overload.
4.) Gain (Trim) - Coarse input gain control. Sets the initial input sensitivity level so that the Fader can be used for fine gain adjustments
5.) Polarity Reverse Switch – Input 2 - When engaged, the polarity of Input 2 is reverse (180° out-of-phase) with respect to inputs 1 and 3. Useful to flip the stereo image with MS stereo
6.) Limiter Switch - Activates both input and output limiters. ON is dual-mono limiter operation, LINK is stereo operation. Output limiter threshold is set in the Setup Menu.
7.) Output Meter – Sunlight-viewable , 20-segment LED meter
8.) Slate Mic/Tone Switch - Two-position switch ,activates the slate microphone in the left (momentary) position, or the tone oscillator in the right (latched) position. Additional options are available in the Setup Menu
9.) Pan Switch - Assigns the input channel to the output bus. Left-only, Center (equal left and right), or Right-only
10.) High-Pass Filter (Low Cut) – Three-position switch engages the high-pass filter.Used to reduce excessive low frequencies.
11.) Stereo Link LED (Inputs 1 & 2) - Indicates that inputs 1 and 2 are linked as a stereo pair. Controlled in the Setup Menu. In L/R stereo link input 2 Fader controls overall stereo level. When in MS position input 1 Gain (Trim) controls Mid, input 2 Gain (Trim) controls the amount of stereo (Side) information and the input 2 Fader controls the overall MS stereo level
12.) Meter Brightness - Controls the brightness of the LED output meter. Each push selects among the four brightness levels
13.) Meter Ballistics - Toggles among the available meter ballistic options: VU-only, peak-only, combo peak/VU, peak-hold/VU.
14.) Headphone Selector Switch - Sets the signal source sent to headphones. Options include: input PFL 1, 2, 3; left output bus; right output bus; Mono (summed left and right); STereo master; RTN - stereo monitor return; MS-mono; MS-stereo; RTN-MS
15.) Headphone Volume - Adjusts the overall volume of the headphones. NOTE: the headphone output is capable of ear-damaging levels. Take care when adjusting among signal sources.
16.) Headphone LED - Indicates signal overload in the headphone and RTN circuits.
17.) Battery Check Button -Press and hold to display the internal and external battery levels on the output meter. Battery level remains for two seconds after button release
18.) Power Switch/LED - Three-position switch, selects between internal battery power or external DC sources, middle position is off. Power LED illuminates when power is on. LED flashes when voltage reaches low limit
Input Panel Features:
1.) XLR Inputs - Transformer-balanced channel inputs. Pin-1 = ground; pin-2 = ‘hot’; pin-3 = ‘cold’. Can be unbalanced by grounding pin-3 to pin-1 of the XLR connector.
2.) Mic/Line Channel Switch - Selects the input level of the adjacent connector. Mic level has 40 dB more gain than line level.
3.) Phantom/DYNamic/T-Power Selection - Selects the microphone powering type of the adjacent input. DYN position turns off all microphone powering. Mic powering is selected per input. NOTE: Use T-Powering only for T-Powered microphones.
4.) Phantom Voltage Selector – Selects between 48V or 12V phantom voltage for all input channels.
5.) Headphone Output – 3.5mm TRS stereo headphone output.Can drive headphones from 8 to 2000 Ohms to required monitoring levels
Output Panel Features:
1.) XLR Master Outputs - Active-balanced outputs. Pin-1 = ground; pin-2 = ‘hot’; pin 3 = ‘cold’. Can be unbalanced by using pin-2 for signal and pin-1 for ground.
2.) Battery Tube - Holds three-AA batteries for internal powering. Accepts alkaline, lithium, or NiHM rechargeable cells.
3.) Return (Channel 4/5) Level Control - Adjusts the gain of the return feed to balance program and monitor signals in headphones.
4.) Return (Channel 4/5) Input - Unbalanced stereo 3.5-mm input connector for return monitor audio. 3.5mm wired tip = left, ring = right, sleeve = ground. Connection used for inputs 4 & 5 when selected in Setup Menu.
5.) Mix In - An input to the master bus designed exclusively to link the Tape Out/ Mix Out of 302, 442, MixPre, or MP-2 to the 302 for additional inputs. Pin-1 = ground, pin-2 = left, pin-3 = right. Shell of TA3 connector must be grounded to pin-1 to open connection.
6.) Channel 4/5 Activation LED - When illuminated, indicates that the return connector is now set as input 4 and 5 in the Setup Menu.
7.) Output Attenuation LED - When illuminated, indicates that the XLR output connectors are set for a level other than the factory default line level.
8.) Tape Out / Mix Out - Unbalanced stereo output on TA3-type connector. Same program as master output. Pin-1 = ground, pin-2 = left, pin-3 = right. Also used to link to the Mix In of a 442 or 302.
9.) DC Input - Accepts DC voltages from 5–18 VDC for mixer powering. Hirose 4-pin connector wired pin-1 negative (–), pin-4 positive (+). Ext DC is completely isolated (floating) from the rest of the circuitry.
