How good are the microphone preamps?
The preamps on all 7-series recordersare superb and unique. We took advantage of the increased power available from Li-ion batteries and developed a preamp that is quieter, exhibits lower distortion, and has far higher bandwidth than any other [present] Sound Devices preamp. They use a large geometry, discrete transistor topology versus the transformer preamps of our field mixers. While bandwidth out to the Nyquist frequency at 192 kHz sampling rate may not be needed for music recording, it is important for scientific test and measurement applications.
