As far as recent portable digital audio recorders go, there has been quite a buzz around the Tascam DR-60D Portable Recorder + Field Recorder. The Tascam proves to have good quality sound as a preamp, but when compared to something like a Zoom H4n, the Tascam does not offer a single built in microphone. Besides having to carry around a separate microphone, the form factor is a bit on the large side (so does that still qualify as a portable recorder?).
Samson's Zoom line of portable recorders have always included a set of microphones, but the new Zoom H6 Portable Digital Audio Recorder takes it to the next level by offering a very modular Mic and Input system among other new advanced features. The Zoom H6 basic kit includes includes an XY Microphone, Module, Includes Mid-side Microphone Module, Four XLR/TRS Inputs, Record Up to 6 Simultaneous Channels, Record Up to 24-bit/96kHz Audio, Doubles as USB Audio Interface, Uses SDXC Memory Cards. Add-ons will be available such as a Shotgun Mic, XLR/TRS Inputs Module, and Hot Shoe Mount. The brand new Zoom H6 Portable Digital Recorder is available for pre-order now via (B&H) Click here.
