CardioidX/Y StereoLewitt Audio DGT 650

Multi-Pattern Condenser Microphone

The DGT 650 is Lewitt’s first USB microphone. Like many of the company’s products, it introduces a few innovative new features, while retaining familiar features from other Lewitt products.

DGT 650 in ShockmountIn a nutshell, the mic is a switchable Cardioid / XY Stereo electret condenser plus a two-channel, 24-bit, 96 kHz ADC that can send output through a variety of output/connection options including iOS and USB. An included breakout box provides a headphone jack for monitoring as well as a stereo analog line in for recording an external instrument through the mic’s ADC.

The mic’s body and grille are the same as is found on most of the LCT studio condenser series. The DGT 650 utilizes a new approach to the backlit interface panel of most of the LCT series condensers; it allows configuration of the mic’s behavior via a “noiseless pushwheel.” Rolling the wheel side-to-side navigates among options, while pushing it selects a specific option or value.

Across the top of the interface panel are icons representing the four “recording modes:”

  1. XY Stereo - two-channel output, with the signal from each of the two small-diaphragm capsules output independently
  2. Cardioid - mono output, resulting from internal summing of the two 90-degree capsules
  3. “Singer/Songwriter” mode, aka Cardioid/Line-in - Two-channel output with one containing the mono Cardioid microphone signal, and the other containing a mono line in signal (such as from a keyboard or guitar)
  4. Stereo line in - Two-channel output containing only the stereo line in; in this mode, the mic capsules’ output is muted

The mic’s two capsules are the same as are found in Lewitt’s LCT 140 pencil condenser. They are described as having a diameter of 17mm. They are mounted in a fixed 90-degree array.

Like most of Lewitt’s LCT microphones, the DGT 650 offers 3-way pad and filter options. Pad values are -10dB or -20dB, and are implemented with capacitors. The high-pass filter is a 12dB cut at either 80Hz or 160Hz.

The mic contains a two-channel monitor system as well, enabling the user to independently set the playback volume level of the mic’s signal, the line in, or a track played back from the host computer. These volume levels are set via the pushwheel interface. When the monitor system is set to play back the mic’s signal exclusively, the front panel lights up the “direct” indicator. When monitoring is set to DAW playback exclusively, the panel lights up “return.” When set to any mix of these two sources, both indicators are lit.

The Lewitt logo on the mic’s front panel lights up to indicate that the input signal has clipped. (It is not yet clear whether this applies only to the mic’s signal, or also to the line-in signal.)

DGT 650 breakout boxThe mic has no onboard analog (XLR) nor USB output; rather, Lewitt uses a proprietary 19-pin connector. The mic must be used with the included breakout box, which provides 4 i/o connectors:

  • stereo headphone out. This is 1/4'' in the pictured prototype, but will be 1/8'' in the production version.
  • stereo line in. This is 1/8'' in the prototype, but will be 1/4'' in production.
  • MIDI
  • 19-pin digital out — this is another of the same proprietary 19-pin locking connectors as is found on the mic itself. The DGT 650 will be shipped with two compatible output cables, one for USB and one for Apple Lightning (iOS/iPhone/iPad).

Because iOS hosts do not provide sufficient power to drive the microphone’s electronics, it has an onboard Li-ion battery that can be recharged via a mini-USB connector on the side of the microphone.

The mic was released in 2014.
