Zoom R16
The Zoom R16 is a portable solid-state audio recorder and mixer. It is commonly used for recording YSTV's OBs. While it can take a simple stereo input (by linking channels 1 and 2) for basic recording, it can also be used to record up to 8 channels of submix for later mastering, to 16/24-bit 44.1kHz WAV. It records to an SD card which is formatted in FAT32 - so has a 4GB file size limit, which becomes a problem when stereo recordings are longer than about 3 hours (in 16-bit mode). This must be taken into account on long OBs like Woodstock or Elections.
It accepts phono and XLR inputs, and has an onboard stereo microphone array. USB cables can be used to daisychain it with another one to make a single 16-channel mixer/recorder. The USB connection also provides power, to phones or LED lights for example. It can be powered from AA batteries.
