Intro

Thank you for choosing a LEWITT DGT 450! 

In brief: It’s one of the most capable USB microphone on the market. It’s compatible with Windows, Mac and 
even iOS devices. It can be used to record vocals, instruments, ambient sound, samples, podcasts and more. 

Be sure to check out our Breakout Box although it’s not included in the package - it’s a clever additional 
accessory available online and at your local dealer. With this little box you will be able to plug in and record your 
guitar, synthesizer, mixing desk or any other line output-equipped device. You can also plug in any MIDI input 
device directly and record everything on seperate tracks in one run ... 

You see, this is way more than a simple USB microphone: it’s your Digital Multi-Tool.

Recording Modes

We’ve  built two  different  recording  modes  into your  DGT  450 to  make  it  more versatile,  we’d  like to  briefly 
introduce them to you here:

Cardioid Mode

 // 

Best used for vocal recording or other applications where you need good rear rejection. 

Singer/Songwriter Mode

 // 

Only availbale with the Breakout Box (not inlcuded). Channel 1 is the cardioid 

mic and channel 2 is the line input. Use this mode for simultaneous recording of acoustic and line sources. For 
example: plug in your guitar to the line input and sing into the microphone to put the two signals on separate 
tracks. If you plug a stereo source into the line input, it will be summed mono (this could possibly cause phase 
issues on some synthesizers).

Setup

Connect the hi-speed 18-pin data connector with the microphone, then connect the USB plug to the computer 
or the lightning connector to your iOS device. If you need to extend the USB cable, be sure to use a HI-SPEED-
compatible USB extension cord. We do not recommend the use of USB hubs, but if you need to, only use a 
powered hub or use the USB port to power the DGT 450. 

OS X (10.6 and up) 

// 

Connect the DGT 450 to the USB port.

Open “system preferences” in the 

 menu at the top of the screen.

Click on the “Sound” icon.
Click the “Output” tab and select “DGT 450”.
Click the “Input” tab and also select the “DGT 450”.

input at 12dB per octave.

 

Pre-Attenuation

 For loud signals to prevent clipping. 

-10 dB of pre-attenuation affect the microphone only.

Operating the microphone

The following will walk you through all the settings of your DGT 450. 
Standard Mode

 //

 This is the default state of the device when you power it on (

 is illuminated white). 

Settings Mode 

//

 This is where you can change all the settings on your DGT 450 including recording modes, 

monitoring options, high-pass filters, pre-attenuation and gain. The illuminated LEWITT logo will turn off as 
soon as the microphone switches to Settings Mode. Press the jog dial 

 to enter the settings mode, to switch 

from setting to setting and rotate it to change the selected setting.

Headphone/Output Gain 

//

 The headphone symbol is lit. Rotate the jog dial to change the output volume. 

ATTENTION

: Your DGT 450 has a professional, built-in headphone amp. Be sure to check your gain settings 

befor using headphones, the signal can be very loud. Honestly, we mean it - this can seriously harm your ears.

Input Gain

 //

 Press the jog dial until the input gain symbol is lit. We use a very fine gain control – there are 

intermediate steps that do not show up on the LEDs. The settings will change depending on the selected 
recording mode. You can set input gain levels for all recording modes individually.

Cardioid Mode selected 

//

 Gain L R will be lit. Rotate the jog dial to change the gain.

Singer/Songwriter Mode selected (only available with the optional Breakout Box) 

//

 Gain L will be lit 

first. This lets you set the gain for the left channel – in this mode, it’s the cardioid microphone. Press the

jog dial; Gain R will now be lit. This lets you change the gain of the right channel – in this mode, it’s the line 
input. 

Recording Mode

 //

 The selected recording mode symbol is lit. Rotate the jog dial to change the recording 

mode if a Breakout Box is connected to the DGT 450. Press the jog dial to switch to the next setting.

Monitoring Mode

 // 

Use the jog dial to blend between tape return monitoring and direct monitoring 

. The 

LED graph 

 shows the mixture of the two modes. Press the jog dial to switch to the next option.

Low-cut Filter

 //

 Set the low cut 

 with the jog dial. Available settings are: flat and 80Hz@12dB/Oct.

Pre-Attenuation

 //

 Set the pre-attenuation 

 by rotating the jog dial the options are 0dB, -10dB.
