The 302 is the essential portable mixer for production companies and camera operators wanting to take control of their audio. The 302 is stunning in size, fl exibility, control and performance; it is the most compact and cost-effective battery-powered professional audio mixer in its class.
302 User Guide and Technical Information Quick Start Checklist Proper setup of sound sources and input devices is quick and easy with the 302. Follow the steps outlined below for basic interconnection. Powering the 302 1. Insert three AA-batteries with + side fi rst into the mixer battery tube.

(fl oating) from the rest of the circuitry. 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.
With the Fader set to unity gain (0 dB or 12 o’clock), make the appropriate adjustments with the Gain (trim) pot. Make coarse gain adjustments with the Gain (trim) pot during setup. Once the gain is set to the desired level, recess the Gain (trim) pot to hide it from the 302’s mixing surface.
-3. Dynamic microphones will operate as normal when phantom power is applied to them. The 302 can provide up to 10 mA to each input at 48 V, suffi cient for the most power-hungry condenser microphones. Many phantom powered microphones do not require 48 V and can be properly powered with 12 V.
fi ltering. Many microphones have on-board high pass fi lters, and the high-pass fi lters on the 302 can be used in conjunction with the microphone’s fi lters to increase the fi lter’s slope.
The 302’s MS matrix uses Input 1 for the Mid signal and Input 2 for the Side signal. Input 2’s Fader controls the overall gain of the MS stereo pair. Input 1’s Fader and both Input 1 and 2’s Pan switches are disabled.
The 302’s Master XLR Outputs and Tape Outputs share the same program content. There is no master level control on the 302. The master is factory-set to unity gain, or “0” dB. XLR Outputs The two XLR outputs are active-balanced connections, each capable of driving long lines.
For most applications the limiters are a signifi cant benefi t and should be enabled. Headphone Monitoring The 302 has a fl exible headphone circuit capable of selecting a variety of audio signals for headphone monitoring. Most professional headphones ranging in impedance from 8 ohms to 1000 ohms can be used with the 302.
302 User Guide and Technical Information HP Monitor Selection Several signal sources can sent to the headphones. The front panel rotary switch selects the signal. HP Sources Description (PFL) 1 PFL solo monitoring of the Channel 1 input signal. The channel is monitored in dual-mono. Pre-Fader, post- Limiter, and post-High-Pass.
When the Tone Oscillator is engaged the inputs are muted. Tone Oscillator Tone is used to set gain levels between the 302 and the next device in the signal path. The Tone Oscillator uses the latch position of the switch. Switch positions can be reassigned in the Setup Menu.
VU (Volume Units) information, its scale corresponds to VU units. Unlike other analog mixers, the 302 is calibrated with its 0 VU reference at 0 dBu, not +4 dBu. If you primarily interconnect with analog video cameras, you may want to change the 0 VU reference to +4 dBu in the Setup Menu.
VU meters are too slow to be used as the sole metering source when interconnected to digital devices. At Factory Default, the 302 has its 0 VU reference level at 0 dBu. The meter reference level can be altered in the Setup Menu.
When linking with a 442 a system of seven microphone inputs is achieved. Generally when linking to a 442, the 442 is used as the master, linking with the 302’s Mix Out to the 442’s Mix In. At the 442 outputs, all seven inputs appear.
302 User Guide and Technical Information Internal Batteries The 302 uses a unique battery tube to hold 3-AA batteries. This robust tube is sealed to prevent potential battery leakage from ruining internal circuitry. The threaded-nickel cap extends beyond the panel to make battery changes easy and quick.The battery tube extends no farther than adjacent XLR connectors.
302 User Guide and Technical Information The Setup Menu The 302 has 18 available setup features. See the Setup Menu Chart for all available options. Setups, typically set-and-forget features, are infrequently changed. With the Setup Menu, these features are easily accessed directly on mixer’s the front panel.
302 User Guide and Technical Information User Default A memory location is available to store user-defi ned default settings. The user default is helpful to save a baseline of settings different than the factory default settings. To save a user default perform the following: 1.
Adjust the 302’s output level via the up/down buttons until the recorder is just shy of clipping as indicated on its meter. 7. If the 302’s Output level is at 0 dB and the recorder is not to its clip level, increase the recorder’s gain control until it is to the clip level.
302 User Guide and Technical Information Setup Menu (v 3.6) Below is the chart of setups for the 302. See Setup Menu on page 15 for instructions on how to enter and navigate the setup menu. Factory default settings are displayed in bold.
