If you’ve ever wished to mix on a large console,
the driver’s seat is now yours.

48 channel mixing

A flexible, dynamic, scalable mixing experience

With almost twice the DSP power of MOTU's award-winning line of "mk3" audio interfaces, the 1248 mixer provides up to 48 assignable input channels. Seamlessly mix live audio signals from the 1248's physical inputs with computer disk tracks and audio streams coming from other networked MOTU AVB interfaces. Make input and output assignments in the Routing grid easily with one click. Instantly show and hide sections of the mixer with convenient sidebar controls. Each input channel strip provides a high-pass filter, gate, four-band parametric EQ, and compressor.

7 stereo aux busses and 4 groups

Control up to 12 independent stereo mixes

Create up to seven stereo aux mixes for monitor mixes and other sub-mixing tasks. Four independent mix groups let you control drum stems, background vocals, or other input groups on a single channel strip with 4-band EQ and the 1248's MasterWorks Leveler modeled after the LA-2A optical compressor. The fourth group includes the 1248's reverb processor. Through Wi-Fi, multiple engineers — or even musicians — can control their own monitor mixes simultaneously from their iPhone or iPad.

Aux bus mixing

Long-throw faders for aux sends

The Aux Mixing tab lets you zero in on a single aux bus and control send levels with long-throw faders, just like hardware consoles that let you temporarily "flip" aux sends to the channel faders…perfect for detailed mixing on any aux bus.

Monitor Mix/Solo Bus

Convenient dedicated monitoring

The Monitor Mix is specifically designed for monitoring. It can mirror any other bus, or act as a solo bus for isolating all currently soloed inputs, aux busses or groups. You can, of course, create additional monitor mixes with the seven available aux busses.

32-bit floating point processing

Virtually infinite headroom

The 1248's mixing and DSP effects engine employs 32-bit floating point processing, which produces virtually infinite headroom for complex mixing and processing calculations, along with an infinitesimally low noise floor.

Modeled analog EQ

Precise and musical equalization

British analog mixing consoles are renowned for their musical EQ profiles. The 1248 meticulously models these classic EQ curves to give you the very same, magical EQ settings found on these coveted desks. Four separate filters are available on every input, including optional low-shelf and high-shelf.

Classic reverb

An all-around verb with tails up to 60 seconds

The 1248's Classic Reverb™ provides three frequency bands with adjustable crossover points, predelay, spread, and reverb lengths up to 60 seconds. Perfect for monitor mixes when tracking in the studio.


Finely crafted vintage compression

The Leveler™ is an accurate model of the legendary Teletronix™ LA-2A™ optical leveling amplifier, known for its unique and highly sought-after Automatic Gain Control (AGC) characteristics. The heart of the LA-2A is the T4 opto-coupler, a photoelectric device with almost magical (signal dependent) self-adjusting behavior that makes optical compressors the tool of choice for smoothing out just about any audio material, from vocals to bass guitar to full-program mixes, without destroying perceived dynamics. The Leveler's controls match the front panel of the original LA-2A: Peak Reduction and Makeup Gain knobs, along with Limiter/Compressor buttons.

Gate and HPF

Gating and high-pass filtering on every input

Each input is equipped with a standard high-pass filter and gate module for removing rumble, environmental noise, and other signal clean-up tasks.
