Interfacing the MixPre or 302 with a Shure FP33
Sound Devices MixPre and the Shure FP33 mixer can be interconnected to combine inputs. An interconnected MixPre and FP33 combination results in the following:

Time code generated in file-based recorders is fundamentally different than time code on a tape recorder. Whereas a tape recorder has a continuous time code reference for each location on the tape, a (broadcast wave) audio file only has a single time code value—from which all time code values are calculated.

“Phantom powering” is a method of providing power to microphones by applying a voltage to the same wires that carry the audio signals. Phantom power can be generated from mixing consoles, mic preamplifiers, or in-line phantom power supplies. All of Sound Devices microphone inputs supply phantom power.

Condition: Early models of Earthworks microphones (see Models Affected) and Earthworks model M30 microphone will become unstable and oscillate with transformer-balanced microphone inputs such as Sound Devices MP-1, MP-2 and MixPre.

Rechargeable AA batteries for internal powering of pro audio gear have historically been poor performers. Alkaline primary cells, and more recently Li-ion cells, are usually the preferred cell chemistry. Fortunately, battery chemistries have evolved — in some applications there is actually a runtime advantage when using the newer NiMH rechargeable batteries with portable gear versus […]
Read The Full Article302 and 442 with Line Inputs
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 […]
