MOTU 1248 User Manual page 34

Stand-alone mixing with wireless control
If you connect your MOTU interface to an Apple
Airport or other WiFi router with a standard
Ethernet cable, you can control its powerful mixing
and DSP effects from your smart phone or tablet,
without a computer — great for live sound mixing
from your iPad, tablet, or other wireless device.
ADAT digital I/O
The 1248, 8M and 16A interfaces each provide two
8-channel banks of optical digital I/O. Connect
outboard digital processors, digital mixers or other
gear: 16 channels at 44.1/48 kHz or 8 channels at
88.2/96 kHz.
S/PDIF digital I/O with SRC
The 1248 provides S/PDIF digital input and output
on standard RCA "coax" connectors. The input is
equipped with Sample Rate Conversion (SRC),
allowing you to input a digital signal running at a
different sample rate than the 1248. See "S/PDIF
with sample rate conversion" on page 53.
Word clock
Each MOTU interface supports standard word
clock synchronization at any supported sample
rate. When the interface is operating at 96 kHz, it
can generate word clock output at either 96 or
48 kHz; the 1x equivalence is available as an option
for word clock output when running at high
sample rates (from 88.2 to 192 kHz). The word
clock OUT port can alternately be used as a THRU
port for word clock daisy-chaining. To configure,
use the LCD menu to navigate to Settings -> Word
Clock Thru Mode.

Comprehensive metering
The large backlit LCD displays all signal activity at
a glance with detailed metering for all analog and
digital I/O. You can access many hardware settings
directly from the front panel.
Headphone outputs
The 1248 front panel provides two independent
headphone jacks with separate volume controls.
You can program the outputs to mirror another set
of 1248 outputs or act as their own independent
outputs. The 8M also offers a single headphone
output.
Precision Digital Trim™
On each interface, all of the analog inputs are
equipped with digitally controlled analog trims,
adjustable in 1 dB increments. The input trims for
mic inputs and guitar inputs can be adjusted from
the knobs on the front panel. You can save your
trim configurations as a preset for instant recall.
Rack mount or desktop operation
Each interface is housed in a sturdy, metal-alloy,
19-inch, rack-mountable unit. The rack mounting
brackets can be removed using a 7/64" hex wrench
for desktop operation.
