Use the Fader to make fine level adjustments during operation. The isolation characteristics of transformers are superior to other balancing techniques and are ideal for the hostile and uncontrolled environments of field production. Make coarse gain adjustments with the Gain (trim) pot during setup. The XLR inputs of the 302 are transformer-balanced. The inputs of the 302 can be used as balanced or unbalanced. the 302 has 75 dB of available gain from mic input to line output. The input transformers in the 302 use premium magnetic core material to achieve high signal handling capability (especially at low frequencies) while keeping distortion to a minimum. transformers are unrivaled by any other type of input for common-mode noise rejection. meaning there is no direct electrical connection. recess the Gain (trim) pot to hide it from the 302’s mixing surface. Mic/Line Level Selection Selects the general input level for each input channel. Gain (Trim) Like traditional mixing consoles. There is no change in gain between unbalanced and balanced connections into the 302. Because of their inherently high common mode impedance. Switch between Mic/Line levels using the switch adjacent to the respective XLR input. Taking into account all gain stages. the 302’s input sensitivity is set with the Gain (trim) potentiometer. full-featured microphone preamplifiers. and “hot” line-level signals. make the appropriate adjustments with the Gain (trim) pot. Channel Fader The Channel Fader is the primary level control used during mixing operation. When inputs are set to the LINE position. Each input has a wide gain range to accommodate nearly all signal types. The 302 easily accepts signals from low-sensitivity ribbon and dynamic microphones. ground pin-3 to pin-1 of the XLR connector. medium-level wireless and condenser mic outputs. 302 User Guide and Technical Information Inputs The 302’s inputs consist of three. Transformers provide galvanic isolation from the driving source. 7 . With the Fader set to unity gain (0 dB or 12 o’clock). Signals are “transformed” magnetically. The fader can be attenuated from off (full counter-clockwise position) to +15 dB above the set Gain (Trim) level (full clockwise position). Once the gain is set to the desired level. When unbalancing. the input sensitivity is reduced by 40 dB.
T-Powering T-powering is a microphone powering scheme used by several European condenser microphone manufacturers. The 160 Hz settings is used when aggressive filtering is required. Most mixer’s high- pass circuits are placed after the mic preamp.6 Features and specifications are subject to change. sufficient for the most power-hungry condenser microphones. It is generally good practice to select the DYN position when microphone power is not required.com for the latest documentation. Visit www. 3. The 302’s high-pass filters feature a 12 dB/octave slope with either 80 Hz or 160 Hz corner (-3 dB) frequencies. especially for speech reproduction. Use T-powering only for T-powered microphones. where all of the high-energy low-frequency signals get amplified. T-powered microphones are not as common as phantom powered microphones. The DYN (dynamic) position does not apply any voltage to the microphone input. There is no voltage difference between the signal pins-2 and -3. Do not apply phantom power when using ribbon microphones. with dynamic microphones for instance.302 User Guide and Technical Information Phantom and T. T-power resistively applies 12 V between the signal pins -2 and -3. Phantom and T-powering are not interchangeable. 8 v. since little usable audio information exists below 80 Hz. High-pass (or low-cut/low roll-off) filters are useful for removing excess low frequency energy in audio signals. If neither Phantom or T-power are required. The phantom voltage level can be set to either 12 V or 48 V and is applied across all inputs where phantom power is selected. Today. it is good practice to turn off microphone powering (DYN position). improperly wired cables can permanently damage the microphone. For most audio applications engaging the high-pass filter is beneficial. T-power can be selected for each input. Wind noise is a common unwanted low frequency signal and a high-pass filter is effective for reducing wind noise. High-Pass Filters Each channel of the 302 has a two-position high-pass filter. use 12 V phantom to extend the 302’s battery life. This voltage is resistively applied to pin-2 and pin-3 of an XLR connector relative to pin-1. The 302’s high-pass circuit is unique because of its placement before any electronic amplification.Microphone Powering This switch selects the type of power that will be applied to the adjacent input XLR. Unlike phantom power. The 302 provides both Phantom and T-power on each channel respectively. When using “red dot” T-powered microphones (reverse polarity T-power) use a polarity-reversing adapter on the input. otherwise damage to the microphone may occur. on the three-pin XLR connector pin-2 has +12 volts relative to pin-3. but many are still in regular use. . When acceptable. Many phantom powered microphones do not require 48 V and can be properly powered with 12 V. Because the 302’s circuit cuts low-frequency signals before amplifying.sounddevices. Dynamic microphones will operate as normal when phantom power is applied to them. Phantom power can capacitively couple noise into the mic inputs with poor mic cables. The 302 can provide up to 10 mA to each input at 48 V. higher headroom is achieved in presence of signals with a lot of low-frequency energy. The 302 provides positive T-power. Phantom Power Phantom powering is a fixed DC voltage between 12 and 48 volts.

and 442 mixers. The power-efficient 302 can operate from three AA alkaline batteries for nearly a production day (less with phantom powering). Sound Device XL-1B accessory cable can be used to link multiple 302 mixers or 302 and 442 mixers. While many users prefer external DC sources to power both their mixer and wireless receivers. At the 442 outputs. The unit connected via the Mix In will contain all inputs. the 442 is used as the master. linking with the 302’s Mix Out to the 442’s Mix In. Link cables must be wired to short pin-1 to connector shell in order to open the Mix In connection. 17 . 302. external DC. Sound Devices XL-3 accessory cable can be used to link a MixPre to the 302 for a five input system. or power off. The unbalanced Mix In connection is directly compatible with Sound Devices MixPre. Generally when linking to a 442. the use of internal batteries is perfectly feasible for both primary and backup powering of the 302. Because of the power supply design of the 302. When the power source falls below the threshold voltage See the Setup Menu Chart the power LED begins to flash. there is sufficient capacitance in the circuit to toggle between internal and external without disruption in audio. To add inputs to the 302. all seven inputs appear. Power Switch and LED The 3-position power switch selects between internal batteries. 302 User Guide and Technical Information Mixer Linking 302A 302B Link two 302 mixers together for higher input The Stereo Output program channel counts by connecting the Tape Out/Mix of 302A is sent directly to the Out of 302A to the Mix In of 302B. When linking with a 442 a system of seven microphone inputs is achieved. The power LED illuminates solid green to indicate good power. Stereo Output program of 302B. adds their input channel to the 302’s output bus. an additional mixer can be connected (linked) into its Mix In connection. A simple connection between those mixer’s Mix Out/Tape Out and the 302 Mix In. Powering The 302 can be powered from either internal batteries or from external DC. Once flashing changing the power source is recommended. the unit takes approximately 10 seconds to fully stabilize its power supply after power-up. Additionally.
Two phantom powered microphones draw twice as much current as one. Several functions of the 302 directly affect current draw in different ways. the external DC metering can be customized for a given battery in the Setup Menu. Microphone The main source of current beyond the idle current draw. 3. The fuse is reset when the voltage is removed. Visit www. with the highest voltage indicated with LED’s lit all the way to the left (green). The threaded-nickel cap extends beyond the panel to make battery changes easy and quick. The external DC connector is a Hirose 4-pin female. low-impedance inputs increases current draw Headphone Output High headphone output levels increase current draw Meter Brightness Current draw is slightly increased with higher illumination intensities Experimentation is recommended to determine battery life for each individual setup and application. If using an AC-to-DC transformer. Remove batteries when the unit is stored for extended periods.6 Features and specifications are subject to change. . Since many different battery types are available for external use. Power Consumption The 302 can vary in the amount of current it draws. an internal poly fuse is opened to prevent mixer damage. 18 v. The 302 can be powered from any DC source with a voltage range of 5 volts to 18 volts.The battery tube extends no farther than adjacent XLR connectors. The power meter is read from left to right. The following list highlights the larger current drawing functions (listed from highest to lowest current draw). Microphones vary widely in their current draw depending on type and phantom voltage applied Output Drive Level Higher output drive levels into multiple. such as a Sound Devices XL-WPH2. The left meter shows the internal battery voltage and the right meter shows the external battery voltage. External DC Sources For extended mixer runtime use an external DC source. If an over voltage is applied to the mixer. This robust tube is sealed to prevent potential battery leakage from ruining internal circuitry. Pin-1 is negative and pin-4 is the positive voltage.sounddevices.302 User Guide and Technical Information Internal Batteries The 302 uses a unique battery tube to hold 3-AA batteries. See Phantom and T-Powering 48 Powering V phantom can draw copious amounts of current out of the batteries depending on what model microphone is used.com for the latest documentation. This locking connector mates to Hirose P/N HR10-7P-4P (Sound Devices P/N XL-H). make certain its output voltage falls in the 5–18 V range and can supply at least 4 watts. The external DC supply is isolated (floating) from the circuitry to minimize ground loop and interaction among devices sharing the same DC source. Power Metering The battery check button indicates battery voltages of internal and external power supplies on the output meter.

The recorder’s level meter can be ignored since the only way for the recorder to clip is for the 302 to clip. 2. Because most recorder’s meter ballistics and scale are different. Adjust the 302’s output level via the up/down buttons until the recorder is just shy of clipping as indicated on its meter. This can be thought of as a master gain control which comes after the 302’s output meter. it is impossible to make the 302 meter exactly match a given recorder’s meter. The dynamic range of the recording is maximized. 10. 21 . 6.”. Fix the recorder’s gain controls with tape so that they do not get bumped. Turn on the tone oscillator via its switch. as they will not activate until just before clipping. It is recommended that the 302’s limiters be turned on at all times. The 302’s meters match the recorder’s meters in that the clip points match. increase the recorder’s gain control until it is to the clip level. However. Make sure to turn down the headphone level and the level going to any amplifiers. Full Scale Tone The following information is intended for users with advanced knowledge of interconnection and gain structure. etc. Connect 302’s XLR outputs to the recording device. or “Mic. to tailor the 302’s outputs exactly to the recording device. Turn the recording device’s input gain control to its detented point (or half-way if no detent). from the 302. When interconnecting the 302 to any recording device. “Tape”. Enter Setup Menu (see The Setup Menu). 3. The advanced way to set gain structure is as follows: 1. “Full scale” is the same as “clipping level.” To activate this full scale tone. 0 dB – Line . the best way to set the level between them is to match the 302’s output clipping level with the recorder’s input clipping level. 8. the attenuator could be set to 50 dB or more. However. If the 302’s Output level is at 0 dB and the recorder is not to its clip level. Turn down headphones and any amplifiers connected to the 302’s other outputs. When this is done and the recording device’s input gain controls are kept fixed. this is irrelevant if the clip levels match. then in 2 dB steps from 40 to 56 dB (mic levels). two things will happen: 1. 7. 2. Exit the 302’s Setup Menu by pressing the PK/VU switch until the startup sequence happens. as a full-scale tone is extremely loud and can hurt the operator’s ears. When properly set. This circuit allows the user to match the 302’s output level to any recording device. 9. So if 40 dB of attenuation is “too hot” for a given device’s mic input. 10 dB – Tape . Be extremely careful when doing this. 5. the 302 includes a full-scale tone output function. 302 User Guide and Technical Information Advanced Gain Structure and Interconnection The 302’s unique output attenuator circuit is adjusted in the Setup Menu. To facilitate matching the clipping levels of the 302’s output to the recorder’s clip level. turn on the tone switch while in the Setup Menu –30 position. 4. the dynamic range of the system is maximized and the 302’s meters will “match” the recorder’s meters. For simple interconnection the following three setting are identical to setting the output switch on the 442 mixer to “Line”. All level metering can be done via the 302’s meter. the 302’s output can be attenuated from full line-level in 2 dB steps from 0 to 16 dB (line/tape levels). Note: The Setup Menu must be exited in this manner or else the setting will not be saved. 40 dB – Mic .
