CAMBRIDGE, MA -- Thursday, December 15, 2011. MOTU is now shipping the 4pre, a compact, half-rack 6x8 hybrid audio interface and mixer. The 4pre connects via FireWire or hi-speed USB2 to a Mac or PC computer and delivers professional audio quality, straightforward front-panel mixing, and plenty of I/O, including four mic inputs with preamps, alternative guitar/line inputs, four channels of analog output, stereo S/PDIF and two stereo headphone outputs. Advanced features include digitally controlled analog trim, DDS (Direct Digital Synthesis) audio clocking for exceptionally low jitter performance, and an instrument tuner.

"The 4pre is the ideal compact audio interface for live recording and mixing situations that require four microphones, or a mix of mics, guitars, and other analog sources," said Jim Cooper, Director of  Marketing at MOTU. "No other interface offers four studio-grade mic preamps, with hybrid FireWire/USB connectivity and  mixing, in such a compact size."

Four mic inputs with preamps
With MOTU's unique hybrid interface technology, the 4pre connects  to any current Mac or PC via high-speed USB 2.0 or FireWire and provides  six simultaneous inputs and eight outputs. Four XLR/TRS "combo" jacks  equipped with clean, transparent preamps provide input for up to four microphones, with individual 48V phantom power and  -20 dB pad. All settings can be adjusted directly on the front panel, or  from the 4pre's CueMix software running on the computer.

Alternately, the four quarter-inch (TRS) analog inputs provide two  hi-Z guitar inputs and two balanced line level inputs, allowing users to  connect guitars, a keyboard, drum machine, or other line-level  instrument. Four quarter-inch (TRS) analog outputs can be connected to powered monitors, stage wedges, or other output  destinations.

All quarter-inch analog connectors are balanced to ensure the  best-possible protection against RF interference, AC hum, and other noise-producing environmental factors.

The 4pre's two guitar jacks provide high-impedance load  characteristics suitable for passive and active pickups alike, to  deliver proper guitar tone to host software.

The rear panel includes S/PDIF digital I/O at sample rates up to 96 kHz.
Easy hands-on mixing for studio and stage
The 4pre front panel provides easy, hands-on mixing of all four  analog inputs. Users can plug in a mic, guitar, keyboard, and  immediately control the mix going to the main outs via four front-panel  knobs. Users can also adjust input trim levels directly from the front panel. Since trim level is handled independently from mix volume, users never have to sacrifice audio quality (initial gain  levels) when adjusting mix levels to achieve the optimum balanced mix.

In the studio, 4pre front-panel mixing can be used for  monitor-mixing while tracking into host software on a computer (to  eliminate software latency during recording), or for playing connected  instruments even when the computer is turned off. On stage, the 4pre can be used for live mixing, either stand-alone or with a  computer.

The 4pre delivers MOTU's award-winning audio interface technology,  pristine audio quality, advanced engineering, and the rock-solid  performance that MOTU interfaces are known for worldwide.

4pre feature highlights

6-input, 8-output audio interface for Mac and Windows -- all channels are available simultaneously and operate independently.

Hybrid FireWire/USB 2.0 connectivity -- connect to a Mac or PC via either bus-powered Firewire or hi-speed USB2.

8-bus digital mixer -- routes and mixes all six inputs to any output pair.

Four separate mixes -- each output pair (main outs, line outs,  S/PDIF out, and phones) can have a completely different mix of all six  inputs, with or without computer tracks.

Four mic inputs with combo jacks -- flexible combo jacks provide  four XLR mic inputs, two hi-Z 1/4" guitar inputs, and stereo line-level  (+4/-10) input. Mic inputs provide individual preamps, phantom power, 20  dB pad, Precision Digital Trim‚Ñ¢, and plenty of gain.

Stereo main outs -- on balanced TRS quarter-inch jacks. Connect  directly to powered speakers (or other line-level analog destination).

Digital I/O -- stereo 24-bit 96kHz S/PDIF in/out.

Two headphone outputs -- independent volume control for each phone  output. Output can be either the same or completely independent.

HD audio -- supports standard sample rates up to 96 kHz.

Precision Digital Trim -- digitally controlled analog trim on all  inputs provides adjustments in approximately 1 dB increments. Fine-tune  the inputs and then save/recall trim configurations.

Front-panel mixing and control -- each analog input has its own  dedicated volume knob. Control multiple mixes with clear feedback from  front panel LEDs and metering.

Front-panel output volume control -- independent volume control of  the main outs and phone output, or mirror the main outs on both phone  jacks.

CueMix FX cross-platform mixing software -- attractive on-screen  graphic mixing with a tuner and audio analysis tools including real-time  FFT display, spectrogram "waterfall" display, oscilloscope, X-Y plot  and linear or polar phase analysis.

Stand-alone operation -- bring the 4pre to a gig, with or without a  computer. Just plug in the included power adapter and you are ready to  go. Need to tweak the mix? Just turn the front-panel knobs.

Expandable -- add additional interfaces for more I/O as your needs grow.

Time code support -- directly resolves to (or generates) time code  via any quarter-inch input or output, without the need for an extra  synchronizer.

Direct Digital Synthesis (DDS) -- a DSP-driven phase lock engine  and internal clock source that produces imperceptibly low jitter  characteristics (below the noise floor), even when the 4pre is resolved  to an external clock source via SMPTE time code.

DC-coupled TRS outputs -- can be used with Volta (sold separately)  to manipulate and sequence voltage-controlled modular synthesizers from a  host DAW.

Plug-and-play operation with your Mac or PC -- compatible with all current and recent generation Macs and PCs.

Includes native 32- and 64-bit drivers for Mac OS X and Windows  7/Vista, including ASIO, WDM, Wave, Core Audio, and Core MIDI. Supports  all popular Mac and Windows audio software.

Fully compatible with 3rd-party software -- 100% compatible with  all host-based effects processing in today's popular audio programs.

Includes audio workstation (DAW) software -- AudioDesk  full-featured sample-accurate workstation software for the Mac OS X with  recording, editing, mixing, real-time 32-bit effects processing &  sample-accurate sync.

Bus-powered FireWire operation -- no need for external power when  operating as a FireWire interface connected to a computer. A power  supply is included for stand-alone or USB2 operation.

Half-rack form factor with removable rack brackets (included) for portable desktop operation or rack-mount installation.


The 4pre is now shipping. Price is $495 USD.
