SOUND DEVICES PORTABLE MIXERS
Compact, portable mixers for studio or field use. Two and three-channel versions, all may be powered from standard batteries or external DC supplies.
MixPre
The MixPre from Sound Devices is a compact, studio-quality two-channel, portable, stereo microphone mixer with headphone monitoring facilities. Its audio performance and comprehensive features make it suitable for the front end of any studio or field production system.
It features two balanced microphone inputs, plus switchable phantom powering (48V/15V), high pass filter (80Hz/160Hz) and peak limiters with limit/clip indication which can be ganged. Each input can be routed to either output bus, as a two channel preamplifier (for stereo, with L and R able to be reversed), or to a common bus as a simple mixer.
A 7-segment LED 2-channel meter facility is provided with switchable display intensity, plus balanced line outputs and unbalanced tape output. The headphone monitor can be switched to tape return, which has adjustable gain to enable level matching. A 1kHz tone generator plus slate microphone are provided.
The MixPre has a durable aluminum chassis to withstand the demands of field and studio environments, with belt loop fixings. The unit is powered by 2 AA size batteries (nominal life approx. 6 hours with phantom off) or external 5V-18V DC (locking Hirose type connector), with a power LED that also gives low power warning.

302
The 302 is a very compact 3-input field microphone mixer, which interfaces with wireless transmitters and receivers, camera audio inputs of all kinds, and external audio recorders. Its microphone inputs share the same circuitry of all Sound Devices field production tools, and are transformer balanced. All controls are accessible on its three main surfaces, there are no hidden controls. The high-efficiency power circuitry runs the mixer from either three internal AA batteries or external 5-18V DC.
The inputs are switchable between microphone level, transformer balanced (Lundahl), or line level. Features include continuously adjustable coarse and fine gain, high-pass filter, pan switches, limiters on inputs and outputs, stereo and MS linking of channel 1 and 2, phantom (48V/12V) or âTâ microphone powering selectable per channel and pre-fade channel monitoring in headphones. Multiple outputs are provided at mic and line level (balanced), together with comprehensive headphone monitoring selection, plus sunlight-viewable LED meters with proprietary software-selected ballistics. An on-board MS stereo matrix is included.
