Using the MixPre II as a USB Audio Interface
The MixPre II Series perform as highly capable and pristine quality USB audio interfaces. They support up to 96 kHz sample rate at
bit depths of 16, 24, 32-bit integer or 32-bit float. The MixPre II’s 32-bit float USB audio path makes it possible to record into a DAW
above 0 dBFS without clipping.
A list of compatible 32-bit float OS and DAW’s can be found at
www.sounddevices.com/32-bit-float-applications
For PC users, the MixPre II appears as a 2x2 audio interface unless a specific ASIO® driver is installed. The latest ASIO drivers are
available for free at
A PC running Windows 10 or higher is required to stream 32-bit float audio. A PC running Windows 7 or below will not stream audio
at 32-bit float. Please install the correct ASIO driver relative to your operating system.
To work with the USB audio from a host computer, it is necessary to route the USB 1 - 4 sources appropriately. To mix the USB
audio from the host computer with live audio from the inputs to the LR bus, use the channel screen and select input source. To hear
the USB host computer audio in the headphones only, switch the HP preset to USB 1,2 or USB 3,4.
The MixPre II is capable of recording and streaming audio to a USB host simultaneously, or recording the USB audio stream out of a
computer directly to its SD recorder.
When connected to a computer as a USB Audio Interface the sample rate of the MixPre II is determined by the computer.
Low-Latency Monitoring
Latency has been minimized while using the MixPre-II as a USB interface. In situations where the throughput latency is higher than
desired, the input can be directly monitored in the headphone output.
To Monitor With Zero-Latency:
1.
Connect via USB-C to the USB port on your computer.
2.
Confirm that the LR Stereo HP Preset is selected.
3.
Select USB 1 for Channel 1 source (MixPre-3 II), Channel 5 source (MixPre-6 II), or Channel 9 source (MixPre-10 II) and
Pan L.
4.
Select USB 2 for Channel 2 source (MixPre-3 II), Channel 6 source (MixPre-6 II), or Channel 10 source (MixPre-10 II) and
Pan R.
OR
1.
Create a custom HP preset that mixes the microphone or input you want to record from with the USB 1 and/or USB 2 feed
from the computer. For example, HP L = Ch1 + U1 and HP R = Ch1 + U2.
2.
Connect microphone or other inputs to remaining channels.
3.
Select USB 1 for Channel 1 source (MixPre-3 II), Channel 5 source (MixPre-6 II), or Channel 9 source (MixPre-10 II) and
4.
Pan L.
5.
Select USB 2 for Channel 2 source (MixPre-3 II), Channel 6 source (MixPre-6 II), or Channel 10 source (MixPre-10 II) and
Pan R.
6.
Connect microphone or other inputs to remaining channels.
7.
Select the appropriate inputs for remaining channels.
8.
Setup your DAW software for a new track with its source being any of the available channels.
9.
Disable record monitoring or mute the channel’s output in the DAW.
You should now be able to hear and adjust the output of your DAW audio through the channels you set to USB 1 and 2 on your
MixPre while adjusting your low-latency feed in your headphones (and send levels to DAW) using the remaining channel knobs.
