CONNECTING TO A MAC OR PC
Connect the M2 or M4 to your host computer
with the supplied USB-C to USB-A cable. If your
computer has USB-C ports, use a USB-C to
USB-C cable (rated for USB2) or a USB-A adapter
(both sold separately). The M2 is powered by its
USB connection to the host computer.
CONNECTING TO AN iOS DEVICE
Recent-generation Apple iOS devices have two
types of connectors: Lightning or USB-C.
For iOS devices with a Lightning port, an Apple
Lightning to USB3 Camera Adapter is required:

M/A/lightning-to-usb-3-camera-adapter
Figure 3-3: The Apple Lightning to USB3 Camera Adapter.
Connect USB-C port on this adapter to a wall
outlet for power. (The M2 and M4 cannot be
powered from the iPad itself. They draw too much
power for 48V, the LCD, etc.)
The USB Type A port can then be connected to the
M2 or M4, or a powered USB hub for connection
to many USB devices.
AUDIO CONNECTIONS
Here are a few things to keep in mind as you are
making audio connections to your M Series
interface.
Mic/line/instrument inputs with preamps
Connect a microphone, guitar or line-level analog
input to the XLR/quarter-inch combo jacks with
either a standard mic cable or a balanced cable
with a quarter-inch plug.
☛ Do not connect a +4 (line level) XLR cable to
the inputs (because of the preamps). Use a
quarter-inch input instead.
Phantom power
If you are connecting a condenser microphone or
another device that requires phantom power,
engage the corresponding 48V phantom power
switch.
Preamp gain
The M series preamps provides 60 dB of gain. Use
the front panel trim knobs to adjust gain as needed
for each input. Watch the input level meter in the
LCD while adjusting gain. Try to adjust gain as
high as possible without clipping, which is
indicated by the red rectangle at the top of the
meter.
