The polarity of the 442 and 442N mixers tone oscillator is inverted between the main outputs and the direct outputs. This polarity "flip" only affects the tone oscillator and not audio signals. (more…)

The 302 and 442 mixer's tone oscillators have several modes of operation. From the Setup Menu, the tone frequency and level can be set. (more…)

Both the 442 and 302 field mixers can decode MS stereo microphone signals. Depending on your workflow you can decide to decode the MS stereo signal in one of two ways: (more…)

The 302, like all Sound Devices mixers, including the 442 and MixPre, can exhibit a static, or crackling sound when gain controls are manipulated when the unit is first powered. This noise goes away as the power supply and filter capacitors become fully charged.

The line-level inputs on the 302 and 442 are attenuated by 40 dB from mic-level and go through the mic transformer. We chose this topology to maintain transformer isolation of line inputs. For our portable field mixers we chose to keep their size small and not have transformers large enough to handle line inputs. The alternative, electronically balancing line inputs along side transformer balanced mic ins, was not practical. The noise penalty is extremely small, since the noise figure of the unit overall is quite low.
