'The Zoom F4 propels your film's sound to a whole new level. With 6-input/8-track recording, super-low-noise mic preamps, and time code with pinpoint accuracy, the F4 offers Hollywood sound at an indie budget. The F4 is equipped with our highest-quality mic preamps. Like the F8, the F4’s mic preamps enable pristine recording and playback at resolutions up to 24-bit/192 kHz. Its impressive audio specs include an extremely low noise floor (-127 dBu EIN) and high gain (up to 75 dB), with +4 dB line-level inputs.' I've used this as a Field Recorder and in the studio as an interface and it's been brilliant! Selling as I no longer need it.
