Page 3: Preface: Mission Statement
Preface: Mission Statement The MT 48 brings reference-class sound to your desktop . It is the first audio interface to unlock the full potential of Neumann microphones, studio monitors, and headphones as well as high class gear from other manufacturers . The MT 48 builds upon the knowledge and experience of our friends, partners and now colleagues from Merging Technologies, famous among recording professionals for state-of-the-art AD/DA converters and networked audio solutions . -
Page 4: What's In The Box
MIDI The MT 48 comes with two USB-C to USB-C cables and one USB-C to USB-A cable as well as an external power supply including adapters for different countries . Please read the Quick Guide and Safety Guide before using the MT 48 . -

. AES67 supports high channel counts even at double and quad sampling rates . The AES67 port is bidirectional, so input and output devices can be connected to the MT 48 at the same time using a standard ethernet switch . -
Page 8: Register Your Product
The MT 48 uses the High Speed protocol supported by USB 2 .0 or higher ports . Should the MT 48 not work properly on a USB 3 .0 (or higher) port, please use a USB 2 .0 port . Some non-Intel USB 3 .x chipsets are not fully backward compatible for use with audio devices . -

At higher sampling rates up to 96 kHz, the channel count reduces to 16 input and 16 output channels At highest rates up to 192 kHz, the MT 48 driver can handle up to 8 input and 16 output chan- nels . - Page 11 Section 2: Software playback Software playback to MT 48 mixer DAW1, DAW2, DAW3 and DAW4 are stereo channels from your computer software to the MT 48 . Per default, DAW1 and DAW2 are activated . These channels appear as stereo channel strips in your MT 48 Mixer .
- Page 12 But it is a useful option in some scenarios, for instance: • If you want to manage your monitoring in the DAW instead of the MT 48 . Direct Routing allows you to address Headphones and speakers without going through the MT 48 mixer .

ADAT Inputs can now be addressed via the channel numbers displayed . Go to SETTINGS → USB I/O → SOFTWARE PLAYBACK – Direct Routing and activate OPTICAL . The ADAT Outs can now be addressed directly in your DAW via the channel numbers dis- played . MT 48 | 13... - Page 14 4 . In the MT 48 Mixer, remove the ADAT Input channels . Go to MENU → STRIPS SETUP and disable all ADAT channels and clear the ADAT Group . Now you can address outboard gear connected to your ADAT converter via driver I/O chan- nels .

Page 15: Daw Setup
To adjust the Latency settings in your DAW, go to Preferences or Studio Setup – please refer to your DAW manual . There will be button to open the Control Panel for the MT 48 that allows you to specify the Buffer Size . - Page 16 MIDI data . Input latency only comes into play when you process an audio input signal in real time . For instance, when you plug a guitar into the MT 48’s instrument input and process its audio signal with amp modeling software .

(by specifying the left or right channel), but you cannot use mono inputs to record ste- reo tracks . Create stereo inputs for all hardware inputs you previously activated in MT 48 USB I/O SETUP . Channel naming is not transmitted to your computer . To avoid confusion, it’s a good idea to name the channels in your DAW accordingly . -
