PREPARATION
Install your host audio software first if you haven’t
already done so, and complete these chapters
before proceeding:
■
chapter 3, “Software Installation” (page 27)
■
chapter 4, “Hardware Installation” (page 31)
RUN THE WEB APP
Before you run your host audio software, launch
the web app to configure your MOTU hardware.
The web app lets you configure important settings
in your audio interface, enable the desired inputs
and outputs, and set up audio streams to and from
the computer.
Sample rate
Choose the desired sample rate for the
UltraLite-mk4 (item #12 in the Device tab on
page 12) and your host audio software. Make sure
the rates for the hardware and software match.
Newly recorded audio will have this sample rate.
Clock mode
The Clock Mode setting (item #13 in the Device tab
on page 12) is important because it determines the
master digital audio clock for your system.
If you do not have any digital audio connections to
your MOTU device (you are using the analog
inputs and outputs only), and you will not be
resolving your host software to optical or another
external clock source, choose
Internal
.
If you have devices connected to the optical ports,
see “Choosing a clock source for optical
connections” on page 34. If you have S/PDIF
devices connected, see “S/PDIF” on page 34.
Audio Interface preset
Click
Launch Quick Setup
(item #9 in the Device
tab on page 12) and choose the Audio Interface
preset. Your MOTU interface is now set up for
operation as an audio interface with any host audio
software. For details about customizing the audio
routing to and from the computer, see “Working
with the Routing grid” on page 49.
