Vendor reps demo’d their wares at the Podcast and New Media Expo exhibit hall. One product that caught my eye was the newest and smallest field recorder from D&M Professional, the Marantz PMD620. Small enough to fit inside a shirt pocket, the Marantz PMD620 is capable of recording 16 or 24-bit MP3 or WAV audio on SD or SDHC (Secure Digital High Capacity) memory cards. According to Marantz’s product brochure, the PMD620 is the only pro handheld recorder that includes a built-in speaker and is equipped with two omnidirectional mics located on the top of the device. External mics can be connected via the built-in 1/8″port (sorry, no XLR ports). The PD620 uses 2-AA batteries (Alkaline or NiMH) that can operate the recorder for up to 5 hours. Scheduled for a November release, the Marantz PMD620 is expected to retail for around $400.
