Zoom H4n Handy Recorder is a professional portable audio system designed for high-quality multitrack recording. It is ideal for use with DSLR cameras, which often have limited onboard audio quality. High-quality built-in microphones and four independent inputs make the Zoom H4n suitable for film, television, journalism, and music production. The recorder includes a powerful effects processor with compression, limiting, reverb, and more, along with auto-start/stop recording, auto level control, 2-second pre-record buffer, MP3 support, 24/48V phantom power on external inputs, and additional advanced features.

Recording is done on SD memory cards, and the recorder can also function as a USB audio interface with up to 24-bit / 96 kHz quality. Included: Zoom H4n recorder, 8 GB memory card, hard carrying case.
