MZ-NH3D
The MZ-NH3D is a simplified Hi-MD recorder that retains essential recording functions while omitting many external inputs. A microphone input is included for direct recording without a PC, but line and optical inputs have been completely removed. Hi-MD compatibility expands recording capacity and supports both compressed and uncompressed recording modes. However, its practical use is quite limited, with the main audio capture being via USB. The microphone input is intended for simple recording on the go. With its built-in rechargeable battery and compact design, portability is a top priority.
