// 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.

//Professional small diaphragm capsule for authentic
recordings of any acoustic event
// Switchable to cardioid polar pattern
// Illuminated user interface for quick and easy
handling even in dark environments
// Recording with iPhone, iPod touch or iPad
// Bus-powered on PC & Mac
// Zero-latency direct monitoring
// Mixable direct monitoring and tape return signal for
host device playback and zero-latency monitoring of
the microphone
// Asynchronus USB transfer: precise internal clock
handles the samplerate timing to avoid jitter and
ensure bit & pitch accurate audio reproduction
//Home studio and live recording

//Podcasts and YouTube productions
//Mobile / outdoor recording
//Streaming
5
// 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).
6
// 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-SPEEDcompatible 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”.

// 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
to enter the settings mode, to switch
soon as the microphone switches to Settings Mode. Press the jog dial
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
10
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
shows the mixture of the two modes. Press the jog dial to switch to the next option.

// Saftey Guidelines
// The capsule is a sensitive, high precision component. Make sure you do not drop it from high heights and
avoid strong mechanical stress and force.
// To ensure high sensitivity and best sound reproduction of the microphone, avoid exposing it to moisture, dust
or extreme temperatures.
// Keep this product out of the reach of children.
// Do not use force on the switch or cable of the microphone.
// When disconnecting the microphone cable, grasp the connector and do not pull the cable.
// Do not attempt to modify or fix it. Contact qualified service personnel in case any service is needed. Please do
not disassemble or modify the microphone for any reasons as this will void users warranty.
// The casing of the microphone can be cleaned easily using a wet cloth, never use alcohol or another solvent
for cleaning. If necessary the foam wind stopper can be washed with soap water. Please wait till it is dry before
