The 828 mk3 is MOTU's most advanced FireWire audio interface. Once again it raises the bar with innovative new features, enhanced standard features that remain unique, superb sound and reliable performance.

MOTU 828 mk3 front panel
The 828 mk3 provides ten channels of pristine 192 kHz analog recording and playback, combined with sixteen channels of ADAT digital I/O and stereo S/PDIF. Expand your system by connecting additional MOTU FireWire audio interfaces or the 8pre mic input expander.

The 828 mk3 is equally well-suited for studio and stage, with or without a computer. As an interface or standalone mixer, the 828 mk3 provides 28 separate inputs and 30 separate outputs, including dedicated main outs on XLRs and two front panel headphone outs.

Connect all of your studio gear, including microphones, guitars, synths, keyboards, drum machines and even effects processors. Record, monitor, route and process all of these live inputs using the professional on-board CueMix FX digital mixer – with no latency and no processor strain on your computer. Apply hardware DSP-driven compression, EQ and reverb to every input and output, independent of your host computer. When recording from the mic/guitar inputs, the 828mk3’s signal overload protection gives you an extra 12 dB of headroom above zero with no digital clipping or harsh artifacts.

After programming the on-board mixing in the studio, unplug the 828 mk3 from the computer and take it on the road for operation as a stand-alone mixer with effects. All mixing and effects parameters are adjustable using the front panel backlit LCD.

The 828 mk3 provides cross-platform compatibility with Mac and Windows and all of your favorite audio software and host-based effects via WDM/ASIO/Core Audio drivers. Or you can use the included AudioDesk workstation software for Mac, with 24-bit recording/editing and 32-bit mixing/processing/mastering.

Two convenient front panel mic/guitar inputs are equipped with high quality preamps, plus overload protection and all the features you need to record any mic or guitar with excellent sound quality.

Each input is equipped with its own 48V phantom power switch and 20 dB pad switch. Both inputs also include a switch that toggles between the low-impedance XLR mic input and the true high-impedance quarter-inch guitar input jack.

Precision digitally controlled analog trim
The preamps provide 53 dB of gain, which you can adjust in precise 1 dB increments using the detented digital rotary encoder. As you turn the encoder, you see graphic and numeric feedback in the front panel LCD, so you know exactly how much gain you are applying. The gain adjustment itself is smooth because it is analog, but the digital control gives you both precision and the ability to save and recall trim settings. You get the best of both worlds: analog trim with digital precision and control.

Precision digitally controlled analog trim is also available on all of the 828mk3's balanced quarter-inch (TRS) analog inputs on the rear panel. Level matching analog inputs has never been easier or more convenient. You can carefully tune the balance among your analog inputs using the CueMix FX software and then save the entire configuration on disk for instant recall. You can create and save as many trim configurations as you need.

V-Limit™ hardware limiter
Both mic/guitar inputs are equipped with V-Limit™, a hardware limiter that helps prevent digital clipping from overloaded input signals. With V-Limit enabled, signals can go above zero dB (where limiting kicks in) to as high as +12 dB above zero with no distortion due to digital clipping.

Soft Clip™
Additional protection can be applied to the mic/guitar inputs by enabling the 828mk3's Soft Clip™ feature, which engages just before clipping occurs and helps reduce perceptible distortion.
Sends

Each mic input has a corresponding rear panel send that allows you to insert outboard gear before the signal goes digital. Any input can be used as a return.

The 828mk3 allows you to connect a wide variety of studio gear, including microphones, guitars, synths, keyboards, drum machines, effects processors and more.

Front panel I/O
In addition to the two mic/guitar preamp inputs on the front panel, the 828mk3 provides two independent headphone jacks with independent volume knobs, one of which also controls the XLR main outs on the rear panel. Alternately, this "Master Vol" knob can be programmed to control any combination of outputs (analog and/or digital). For example, it can control monitor output for an entire 5.1 or 7.1 surround mix.
Discrete inputs and outputs

The phone jack below the MASTER VOL knob labeled "(MAIN)" is hard-wired to (mirrors) the XLR main outs. In all other cases, inputs and outputs are discrete. For example, using a mic input does not "steal" an input from the TRS analog I/O bank. Even the second headphone jack operates as an independent output with its own volume control, although you can program it to mirror any other output pair (such as the XLR main outs).

Digitally controlled analog input trim
All of the 828mk3's analog inputs are equipped with digitally controlled analog trim controls that allow adjustments in precise 1 dB increments. The mic/guitar input trims can be adjusted using front-panel digital rotary encoders that provide feedback in the front panel LCD. All analog inputs, including eight TRS analog inputs, can be trimmed using the CueMix FX control software for Mac and Windows.

This allows you to fine-tune your trim settings for synths, effects modules and a wide variety of analog inputs for optimum levels. Different trim configurations can then be saved as files on disk for instant recall.

Rear panel I/O
Eight balanced (TRS) 24-bit analog inputs and outputs, as well as two XLR main outs and the two preamp inputs, can operate at sample rates up to 192 kHz (a total of ten analog inputs and outputs). Two optical banks provide 16 channels of ADAT optical at 48 kHz, 8 channels of S/MUX optical I/O at 96 kHz or two banks of stereo TOSLink at rates up to 96 kHz. The banks operate independently, allowing you to mix and match any optical formats. RCA S/PDIF connectors also supply independent stereo digital I/O.

† The two optical banks provide 16 channels of ADAT optical at 48 kHz, 8 channels of S/MUX optical I/O at 96 kHz or two banks of stereo TOSLink at rates up to 96 kHz. The banks operate independently, allowing you to mix and match any optical formats.

Control room monitoring
Powered monitors can be plugged directly into the outputs of the 828mk3 and you can attenuate the output from the software or the front-panel MASTER VOL control. Main out volume is not limited to stereo operation: quad, 5.1, 7.1 and even user-defined configurations are available. You can even program the 828mk3 to control all 30 outputs with the MASTER VOL knob.

The 828mk3 is an audio interface, but it's also a 16-bus digital mixer, complete with EQ, compression and reverb.

The 828mk3 is really two devices in one: an audio interface plus a 28 x 16 digital mixer. In fact, you could even think of the 828mk3 as a digital mixer in a single rack-space form factor.

Operating as either a computer interface or stand-alone, the 828mk3 provides DSP-driven digital mixing with effects processing (reverb, EQ and compression) for all 28 inputs. You can connect all your gear and then mix, process and monitor everything from the 828mk3’s main outs or headphone jacks.

A 28 input by 16 bus digital mixer with effects
All I/O is routed to the on-board 16-bus (8 stereo) digital mixer driven by hardware-based DSP with 32-bit floating point precision. The mixer allows you to apply no-latency effects processing to inputs, outputs or busses directly in the 828mk3 hardware, independent of the computer. Effects can be applied when the 828mk3 is operating stand-alone (without a computer) as a complete rack-mounted mixer. Input signals to the computer can be recorded wet, dry, or dry with a wet monitor mix (for musicians during recording, for example).

Complete mixing at your fingertips
All of the mixer settings in the 828mk3 are accessible from the programmable front-panel backlit LCD. You can also launch the CueMix FX™ control software for Mac OS X, Windows XP and Windows Vista. CueMix FX provides complete on-screen access to the 828mk3's on-board, hardware-based mixing environment.

CueMix FX gives you comprehensive graphic control over your mix.

CueMix FX is a completely new software front-end with attractive graphic mixing, graphic editing of parametric EQ and a convenient tabbed interface for quick access to all 828mk3 mixing features, digitally controlled trims and other settings.

CueMix FX can be operated side by side with any host audio software for Mac or Windows, and it can be controlled from the Mackie Control Universal Pro automated worksurface.

One window with convenient tabs
Three separate tabs show inputs, mix busses and outputs. Click the "Focus" button on any channel or bus to edit its settings in the area on the right-hand side, which provides separate tabs for graphic editing of parametric EQ, compression and other effects. Each channel strip displays a graphic thumbnail of EQ curves, compressor settings and other channel specific parameters. There is also a section for talkback and listenback.

Eight stereo buses
The 828mk3 supports up to eight separate stereo mixes assigned to any eight digital or analog output pairs. For example, you could set up separate monitor mixes for the main outs and headphone outs, while two additional stereo buses could be used for send/return loops to reverb units or other outboard gear. Each mix can support all 28 inputs (8 TRS analog, 2 mic, 16 ADAT optical digital and stereo SPDIF digital).

DSP resources for mixing and effects
The 828mk3's flexible effects architecture allows you to apply EQ and compression on every input and output (a total of 58 channels), with enough DSP resources for at least one band of parametric EQ and compression on every channel at 48 kHz. However, DSP resources are allocated dynamically and a DSP meter allows you to keep tabs on the 828mk3's processing resources.

Each input, output and mix bus provides a send to the Classic Reverb processor, which then feeds reverb returns to mix buses and outputs, with a selectable split point between them to prevent send/return feedback loops.

Talkback and Listenback
CueMix FX provides Talkback and Listenback features. Talkback allows an engineer in the control room to temporarily dim all audio and talk to musicians in the live room. Conversely, Listenback allows musicians to talk to the control room. For Talkback, you can set up a dedicated mic in your control room and connect it to a mic input on your 828mk3. For Listenback, you can set up a dedicated listenback mic in the live room for the musicians and connect it to another mic input.

Stereo operation
Two channels can be grouped to a single fader for stereo operation. Two stereo panning modes are available: balance and width. Balance mode works much like a normal stereo balance control, one channel fades in and the other fades out. Width mode collapses the stereo image to mono by adjusting the relative pans of each channel gradually to center.

For stereo inputs, an optional M/S (mid-side) decoder can be enabled with adjustable width control and software-swappable inputs.

Software metering
Signal activity of all inputs, busses and outputs can be monitored via the meters pane. In addition to the meters present on individual channels, a high-resolution meter and output bus activity associated with that channel can be displayed in the primary status window.

Effects programming
The EQ, compression and reverb tabs give you complete access to the 828mk3's on-board effects, and because they are driven by hardware DSP inside the 828mk3, they won't tax your host computer's CPU. You can even use the effects without a computer connected.

The tabs shown above let you focus on one channel at a time and edit its settings using the high-resolution graphic display. But EQ and dynamics settings can also be edited on all channels in line (within each channel strip), where you can compare critical settings side-by-side, as shown below.

Front-panel LCD access to all mix settings
All of the mixing features described on these pages are available during stand-alone operation, and all of them can be accessed from the front panel LCD. This means you can program your mixes with the CueMix FX software in the studio and then take the 828mk3 on the road as a stand-alone digital mixer. Tweak your mix on location from the front panel.

828mk3 Classic Reverb
Apply smooth, detailed reverb with several room models, three independent frequency bands and length up to 60 seconds.

The 828mk3's Classic Reverb™ provides five different room types, three frequency bands with adjustable crossover points, shelf filtering and reverb lengths up to 60-seconds.

Each input, output and mix bus provides a send to the Classic Reverb processor, which then feeds reverb returns to mix buses and outputs, with a selectable split point between them to prevent send/return feedback loops.

828mk3 7-band EQ
Modeled after analog British console EQ's, known for their highly musical gain/Q settings, the 828mk3's EQ provides a high pass filter, low pass filter, two shelving or parametric filters and five parametric bands.

The 828mk3's EQ section provides 7-band parametric EQ modeled after British analog console EQ's, featuring 4 filter styles (gain/Q profiles) to effectively cover a wide range of audio material. LP and HP filters are also supplied with slopes that range from 6 to 36 dB per octave.

EQ settings can be adjusted graphically by dragging control points on the large graph in the main EQ tab, as shown above, or using the knobs for individual bands in each channel strip.

828mk3 Vintage compression
The 828mk3's flexible dynamics processing includes a high-quality conventional compressor, plus a leveling amplifier modeled after the legendary LA-2A™ optical compressor.
Convention compressor

Two forms of compression are supplied: a conventional compressor with standard controls for threshold, ratio, attack, release and gain.

Adjust the threshold graphically while viewing accurate, long-throw metering in the compressor section of the CueMix FX software.

Leveler (automatic gain control)
The 828mk3 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.

Conventional compression and limiting with threshold, attack, ratio, release, etc. do not apply here: 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 828mk3 Leveler controls match the front panel of the original LA-2A: Gain Reduction and Makeup Gain knobs, along with Limiter/Compressor buttons.

828mk3 MIDI
The 828mk3 includes a 16-channel MIDI interface that provides sample-accurate timing with supporting software.

Connect a MIDI keyboard, sound module or control surface, and you are ready to go. The FireWire cable carries both MIDI and audio so you don't need to connect an additional USB cable for MIDI.

828mk3 Expansion & drivers
Expand your 828mk3 system and run it with all your favorite audio software.
Adding more I/O to your 828mk3 system

As with other MOTU FireWire interfaces, the 828mk3 supplies two FireWire jacks so it can be daisy-chained with additional MOTU FireWire audio interfaces or other devices.

The 828mk3 is also fully compatible with the 8pre, a single rack MOTU interface that adds 8 mic preamp inputs to the 828mk3. Because the 8pre connects to the 828mk3 via ADAT optical, its mic inputs are fully integrated into the 828mk3's on-board CueMix FX digital mixer.
Drivers and AudioDesk workstation software

The 828mk3 provides CueMix FX and drivers for Mac (OS X) and Windows (XP and Vista) for cross-platform compatibility with virtually all audio software via WDM/ASIO/Core Audio drivers.

The 828mk3 includes AudioDesk®, the advanced workstation software for Mac OS X with 24-bit recording and editing, along with 32-bit mixing, processing and mastering.
