The Marantz PMD620 MK2 is a hand-held digital audio recorder that records to SD flash-card media in either PCM (.WAV) or MP3 formats, in stereo or mono, using internal microphones, external electret or dynamic microphones, or the line input socket. Rugged, lightweight, compact, and easy to operate with password protection and file encryption it is well suited to a wide variety of applications such as journalism, education, medical and security.
PMD 620 MKII
The PMD620 MK2 has an integral stereo electret microphone for simple recording, and an 'intuitive control surface' for single-handed operation, including a thumb-operated transport wheel and illuminating record button. Journalists will appreciate the non-destructive onboard editing, with non-destructive cut-and-paste 'Copy Segment' editing to create new sound files. Transcription is simple with the 'Skip Back' function, and file transfers to a computer are drag-and-drop via the USB 2.0 connectivity.
Building upon the feature set of its predecessor PMD620, the PMD620 MKII includes a linear style 'Retake' function; where 'a simple button press' takes the user back through the previously recorded audio to create a 'drop-in point' for overdubbing. Additionally, the new built-in 'SD Card Check' function makes it easy and convenient to check the compatibility of any SD/SDHC card inserted.
The rugged 'premium black' casing, password protection and file encryption security features complete the updates to be found on the MKII. Recordings can be secured from unauthorised access, MP3 files can be encrypted to MPS and WAV files to WAS files. Both MPS and WAS files utilise a 4-digit password protection feature so only those with the password can open and play files.
A high contrast, low power draw organic LED (OLED) screen guides the user through intuitive set-up and operation. Recording settings are selectable between those for high-quality music recording through to extended voice recording. SD cards and SDHC flash cards are supported, with recording file size limited only by card capacity. Recording time with a 4 GB card extends from 3 hrs 44 mins for stereo PCM at 24-bit / 48 kHz, to 283 hrs 44 mins - almost 12 days - for mono MP3 at 32 kbps.
The front surface has two microphone grilles, level and overload LEDs and a low-power OLED screen to display menus. Large stop/cancel, record pause, record buttons are conveniently in line; the multi-function thumb-wheel adjusts volume, menu navigation, file navigation, play and pause. A 'Display' button is used to alter the screen contents and select inputs and other parameters; the 'Skip back' button is used in play or play pause modes. On the left hand side there are sockets for stereo headphones, line out and remote jack sockets, and a co-axial input for an external DC supply. If the recorder is operating under battery power, when the external power is supplied the recorder will immediately begin using external power, useful if the batteries are going flat in the middle of an interview! Removing the external power will cause an immediate switch to the internal batteries, again useful protection from unexpected loss of mains power.
On the opposing side there are a sliding power switch, which has no effect if the recorder is in record or record-pause modes and a key-lock slide switch to lock all functions. Both these may be found extremely useful when leaving the microphone un-attended at, say a press conference, on the podium. Two further buttons are placed to adjust record level up and down with the user's thumb.
On the top, there are extensions of the microphone grilles, which curve over from the front surface, and sockets for line in and stereo microphone. The bottom has a covered USB socket and a covered slot for the SD card. The rear has a small grille for the mono integral loudspeaker, and a battery compartment taking two standard AA size cells. Alkaline or Ni-MH types may be used. About four hours recording may be expected from 1450mAh alkaline cells: if the batteries run out during recording, the recording stops automatically, the file information is updated, and the recorder shuts down, which is why the type in use should be set in the menu before recording!
Either stereo or external mono microphones may be used. An attenuator offers 12 and 24dB of level reduction, and a microphone power setting provides 5V DC power for use with professional microphones (recommended by Marantz). The bass-cut function will be useful on location.
