The H1n's X/Y microphones capture high-quality stereo sound and support up to 24-bit audio at sample rates of 44.1, 48, or 96 kHz in WAV and various MP3 formats. With the H1n, we have redesigned user-friendliness. With just one press of a button, you can easily record songs, audio for film, lectures, podcasts, and more. The new 1.25" monochrome LCD display is also easily readable in the brightest lighting conditions. An advanced built-in limiter provides a distortion-free signal up to 120 dB SPL and captures even the loudest sounds cleanly. A low-cut filter also helps avoid pops and unwanted rumble at low frequencies. With the overdub function, you can add audio layers for a richer and fuller sound recording. The H1n's playback speed control allows you to transcribe music, interviews, and other types of recordings without changing the pitch. An ⅛" stereo microphone/line input enables recording with your external microphones or other sound sources and provides a power supply (2.5 volts). You can connect headphones via the ⅛" headphone output with a separate volume control. You can also use the H1n's built-in speaker to listen to your recordings. The H1n's USB port offers a digital output for the stereo mix and allows data to be sent to and from your computer. It also enables the use of the H1n as a USB microphone and as a microSD card reader.
