    (floating) 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, sufficient for the most power-hungry condenser microphones. Many phantom powered microphones do not require 48 V and can be properly powered with 12 V.

  • Page 10: Pan Switches

    When possible, attempt to equalize at the sound source with microphone selection, use of windscreens, microphone placement, and on-board microphone filtering. Many microphones have on-board high pass filters, and the high-pass filters on the 302 can be used in conjunction with the microphone’s filters to increase the filter’s slope.

  • Page 11: Stereo Linking Of Inputs 1 And 2

    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 significant benefit and should be enabled. Headphone Monitoring The 302 has a flexible 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.

    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.

  • Page 17: Ballistics Lock

    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.

  • Page 18: Mixer Linking

    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.
