Marantz PMD670 Solid-State Digital Audio Recorder

Marantz PMD670 Solid-State Digital Audio Recorder

The Marantz PMD670 records 16-bit 48kHz uncompressed linear PCM audio to Compact Flash memory cards. The solid-state storage medium allows for faster media acquisition via direct file-transfer to any computer, using the USB file-transfer protocol. The audio files can be imported to any NLE system, such as the Department’s Final Cut Pro, iLife, or Logic software suites.

The Marantz PMD670 connects to audio equipment via mic-level balanced XLR or line-level unbalanced stereo-RCA inputs. It can record up to about 180 minutes in mono setting, or 90 minutes in stereo.

Marantz PMD670 Audio Kit

The F&DM Equipment Checkout Lab releases the Marantz PMD670 Solid State Recorder in an Audio Kit package.

This package includes:

  • 1GB CompactFlash Card
  • AC660PMDU AC/DC Adapter
  • NiMH AA Rechargeable Batteries (16)
  • Kodak K6200 1-Hour Rapid-Charger
  • USB A-to-B Cable
  • XLR Cable
  • Neck Strap
  • Operating Manual
  • External Cardioid Condenser Microphone
    • AKG C535EB Cardioid Condenser Microphone

Technical Specifications and Settings

The PMD670 is designed for the following audio connections:

  • Balanced microphone-level input, with Phantom-power (+48V) option — XLR input
  • Unbalanced line-level stereo — RCA input
  • Digital-audio — RCA coaxial input

As with the PMD660, the PMD670 is set to record in PCM 48K Linear audio, optimally configured for import into Final Cut Pro.

Unlike the PMD660, many of the PMD670’s controls have been externalized. The following settings are recommended:

  • PRE REC: On
  • ANALOG OUT: Stereo (Center)
  • MIC ATTEN: Off
  • ANC: Flat
  • LEVEL CONT.: Manual

For more details covering the various settings, please refer to the User Guide.

Channel and Connection Settings:

The PMD670 allows a total of nine different combinations of input settings. It is important to be aware that the channel-setting and the connection-setting can be defined independently of one another. If both settings are not taken into account, the user’s recording may wind up with unintended and undesirable results.

In summary there are four channel-settings to consider:

  • MONO: The Left Channel connection jack functions as the primary input.
  • LR MONO: Both the Left and Right Channel connection jacks function as a combined primary input, mixing the two signals into a single mono track. Also know as “mixed mono” input.
  • STEREO: The Left and Right Channel connection jacks function as a discrete primary input, recording the left and right signals into a respective stereo track.
  • DigiIn: Special setting for digital signal recording.

In summary there are three connection-settings to consider:

  • INT MIC (Internal Microphone): The mic built into the PMD670. Generally not recommended for use, as these microphone inputs are inferior in quality as compared to using a dedicated-purpose external microphone device.
  • MIC (Microphone): Signal is recorded at microphone-level input volume via user-defined connection (typically XLR) — presumably from an external microphone or other mic-level signal-source.
  • LINE: Signal is recorded at line-level input volume via user-defined connection (typically RCA) — presumably from an external line-level audio-source device.

So, if a user wishes to use an external microphone, they should make sure to set the PMD670 connection to “MIC” and not “INT MIC”; one such example of a common mistake.

Other Details

The Phantom-power option (+48V) for the XLR connectors should only be used for such type microphones. Engaging the Phantom-power option in conjunction with a battery-power microphone may have particularly harmful effects, such as permanent damage to the connector due to voltage overload. Users should take care to confirm that the proper settings correspond with the microphones they are using accordingly. It is also recommended that the Phantom-power be switched off before connecting or disconnecting a Phantom-powered microphone from the audio recorder, so as to prevent any potential damage from voltage spikes and drops.
