About the Soundcraft Ui12

In-depth control from... wherever

Control what's happening onstage with Soundcraft's Ui12 mixer and indulge in all the sonic special effects you like. You set the mixer up like a stage box, connecting microphones and other audio sources to the inputs and powered speakers or amps to the outputs. After a Wi-Fi connection is made with the mixer, you use your smartphone, tablet, or laptop to wirelessly control the mix from wherever you need to be. Need to hand over mixing duties at some point during the set? Have some musicians who like to control their own mix? Up to ten devices can control the mix at the same time, but you can limit the functionality of each to prevent someone from tweaking a wrong monitor channel.

I/O features

The Ui12 features 8 microphone inputs, 4 of which can also accommodate 1/4-inch plugs for line-level instruments like keyboards. You'll also find RCA and USB inputs for playing music on breaks or for background beats. The master outputs deliver the front-of-house stereo mix to your amplifiers, while two auxiliary outputs take care of monitor mixes.

Get famous guitar sound

The first two channels feature high-impedance inputs that you can plug your guitars into directly. The Ui12's software includes DigiTech® Amp Modeling which creates the virtual amp and cabinet combination of your choice and allows you, for example, to sound like you're playing through a Marshall stack without any actual amp or cabinet set up onstage.

Signal processing by Harman

Soundcraft's parent company also happens to make some of the world's finest sound processors, so it's no wonder the Ui12 is packed with so many cool effects. For dynamic control, a dbx® compressor, de-esser, and noise gate can be applied to every channel. To add spatial effects, you can use Lexicon's legendary reverb, delay, and chorus effects. With a 4-band parametric equalizer on each input, a 31-band graphic EQ on each output, plus a graphic RTA display with each EQ, you can craft individual instrument and room tones to perfection. And to top it off, a dbx AFS2 advanced feedback suppressor on each output automatically keeps the sound under control.

Features

Overview: The Soundcraft Ui12 is a 12-channel, rack-mountable digital mixing and multi-track recording system with a flexible I/O matrix, pristine sound quality, intuitive wireless control, and roadworthy reliability, all in a compact design that only takes up 4 rack spaces. The Ui12 features 8 balanced inputs incorporating Studer-designed mic preamps - 4 XLR and 4 XLR/1/4" combo jacks, with two of the combo jacks accepting instrument-level signals. Additional inputs include stereo RCAs for consumer playback devices, and a USB input for 2-channel audio playback from a USB memory stick. Other key features include: 4-band parametric EQ, dbx dynamics, Lexicon reverb, chorus, and delay on all inputs; along with 31-band graphic EQ, dynamics, and AFS² (Automatic Feedback Suppression) on all outputs. Four outputs are provided, 2 Master and 2 Auxiliary, that can be individually controlled from up to 10 tablets or smartphones using the Ui12's built-in Wi-Fi, allowing stage musicians to be in control of their own monitor mix.

Connections

Inputs: The Soundcraft Ui12 includes 8 Inputs consisting of 4 XLR and 4 XLR/1/4" combo jacks, all using Studer world-renowned microphone preamps. Inputs 1-4 are XLR/1/4" combo jacks, accepting balanced or unbalanced signals, inputs 5-8 are balanced XLR connections.

  • Instrument Inputs: XLR/1/4" inputs 1 & 2 can be used for instrument-level signals, letting you plug a guitar or bass guitar directly into the mixer. These inputs feature a Hi-Z (high impedance) setting for instrument use, and include multiple DigiTech guitar amp and cabinet modeling presets that can be applied. Each of the amp modeling presets includes controls for Gain, Level, Bass, Mid, and Treble.
  • Line In: A set of front-panel stereo RCA jacks lets you run consumer-level audio signals into the mixer such as a CD or MP3 player, or a headphone output from a portable player. The Line In signals feature their own L/R channel paths that get combined with the overall output mix.
  • USB Play: A front-panel type-A USB port can be used for 2-channel playback from a USB memory stick, letting you add background music or pre-recorded vocal/backing tracks to the output mix. Compatible formats include: MP3, AAC, WAV, OGG, AIFF, and FLAC files.

Outputs:

  • Master Outputs: Two balanced XLR and 1/4" connectors provide the main stereo Left & Right mix output. Corresponding LEDs for each channel will light to indicate signal present on the outputs. Two rotary controls, Mix L & Mix R, adjust the audio level for each output channel.
  • Auxiliary Outputs (Aux): Two balanced XLR connectors provide individual monitor output mixes for stage and studio musicians. Both the Master and Aux Outputs can be controlled by up to 10 connected smartphones or tablets using the Ui12's built-in Wi-Fi.
    • AFS²: Each of the two Aux Outputs and the two Master Stereo Outputs features dbx AFS² (Automatic Feedback Suppression) technology that uses 12 intelligent "live" filters to detect and eliminate feedback across the audio spectrum. The live filters in the AFS² system can detect when they are no longer needed and remove themselves from the audio path.
  • Headphones: Two front-panel 1/4" headphone outputs are provided with a single rotary Level control that affects both outputs.

Additional Connections & Indicators: Recessed panels on both sides of the Ui12 include the following connections:

  • Ethernet: An RJ-45 port can provide a wired Ethernet connection to a computer or network for configuring and controlling the Ui12.
  • Wi-Fi Indicator: A front-panel LED will light solid to indicate the built-in Wi-Fi is working properly.
  • USB 1&2: Two side-panel USB-A ports can be used for importing/exporting Show and Snapshot files, and for software updates.
  • Footswitch: A 1/4" jack lets you use an optional non-latching footswitch (sold separately) to toggle through configuration selections. Footswitch functions can be assigned in the Settings menu.
  • Power Connector & Power Switch: The Ui12 includes an 18VDC/1.3A external power supply that connects to the mixer's side-panel, along with the power switch.
  • Reset: A recessed push-button will "soft reset" the Ui12 if pressed once. If held down for 10 seconds while powering the unit on, only the Network settings will be reset. A full reset, that reverts the unit back to factory default, can be done if required. Please see Owner's Manual for full procedure.

Access & Control

Wired & Wireless Operation: The Soundcraft Ui12 uses built-in web server technology to enable computer, tablet, and phone-based in-browser control of all functions, without the need for downloading apps onto the controlling devices. The Ui12 is compatible with iOS, Android (web browser 4.4 or higher, or Chrome), Windows, Mac OS, and Linux web browsers.

  • Wi-Fi: The mixer's built-in Wi-Fi lets you easily connect to it wirelessly by searching and selecting the Soundcraft Ui12 from your device's Wi-Fi menu. Once connected, all configuration settings can be accessed and setup using that device. The browser-based software is available in two versions - small screen, which is optimized for phone-size devices, and large screen for tablets and computers. A front-panel Wi-Fi antenna can be swiveled and rotated for optimum placement.
  • Ethernet: The Ui12can also connect into an existing Wi-Fi network or wired LAN (Local Area Network) using the RJ-45 Ethernet port, letting you configure and control the mixer from a computer on the same network. The built-in configuration software lets you edit Wi-Fi and LAN settings, along with configuring access and control options for additional users.

Multi-User Interface: The Ui12 allows up to 10 wireless devices to be connected to it, allowing you and 9 other musicians to configure and control individual monitor mixes during a live performance. As the "administrator", you can control the Master Output, as well as set restrictions on which parameters each individual user can access, letting them change their own mix, but not others or the Master Output mix.

Signal Path

Channel Configuration: The Soundcraft Ui12 features a flexible I/O matrix that lets you route any input signal to any output, either Aux or Master. Up to 12 inputs can be used simultaneously - 4 XLR, 4 XLR/1/4" combo jacks, 2 line-level, and 2 digital. Channel Sub Groups can be assigned for quick control of multiple tracks (i.e. individual drum kit channels can be grouped to a single Sub Group fader). VCA Groups are also provided, letting you change the level of multiple channels simultaneously from the VCA Master, with all associated VCAs keeping their level-offset. Each Input and Output channel features a Real Time Analyzer (RTA) for displaying a spectral view of the audio signal. Other channel parameters include:

  • Gain: Each input channel has a gain adjustment ranging from -40dB to +60dB. A corresponding Clip indicator will light if the input signal reaches the distortion point.
  • Phantom Power: +48V of phantom power can be applied individually to each input channel if connecting a condenser microphone.
  • Phase Reverse: Inverts the phase of the incoming signal by 180˚, for eliminating unwanted frequencies that may result in feedback, or to correct the sound when certain frequencies become either "cancelled" or "reinforced" while in-phase.
  • HI-Z (Channels 1 & 2): This high impedance setting lets you plug a guitar or bass guitar directly into the mixer.
  • DigiTech Processing (Channels 1 & 2): Lets you select from various DigiTech guitar amp and cabinet emulations when running a guitar through Inputs 1 or 2. Amp head and speaker cabinet can be individually assigned.
  • Input Delay: Lets you delay that channel's signal from 1-250ms. This can compensate for the delay caused by microphones placed across a large stage.
  • Mute: Shuts off the incoming audio signal.
  • Solo: Lets you listen to the selected channel individually.
  • Pan/Balance: Positions the incoming signal inside the stereo field.
  • Fader & VU Meter: Each channel strip includes a virtual fader for adjusting the signal level, and a corresponding VU (level) meter.
  • Channel Name: Each channel can be named for easy identification.
  • HPF & LPF: High- and low-pass filters can be applied to each input and output channel, with a selectable cutoff frequency between 20Hz and 1kHz for the HPF, and 1kHz and 22kHz for the LPF. Three slope types are available - 12dB, 24dB, and 36dB.
  • Parametric EQ: Input channels can have a 4-band parametric EQ applied to them, with options for:
    • Band: Each band is selectable from 20Hz-22kHz.
    • Q: Determines how wide a range of frequencies the selected Band affects. Range: .05-15
    • Gain: Provides ±20dB of boost/cut to the selected frequency.
  • dbx Dynamics: Three types of dbx dynamics are available for input and output channels - Gate, Compressor, and De-esser, each with multiple parameters for fine-tuning.
  • Lexicon Effects (FX): The Ui12 has three internal Lexicon FX processors - Reverb, Delay, and Chorus. Effects can all be individually applied to input channels, and have multiple parameters for fine-tuning the effects.
  • Graphic EQ: Auxiliary and Master Outputs can have a 31-band graphic EQ applied to them, with band selectable between 20Hz and 20kHz with ±15dB of boost/cut.

Additional Features & Specifications

Shows & Snapshots: The Ui12 mixer lets you save and store the current configuration for all channels as a Snapshot, letting you quickly recall those configuration settings. A common usage for Snapshots is to have one Snapshot per song in a set list. At the end of a song, the next Snapshot can be recalled, setting up the mixer for the next song. Multiple Snapshots can be saved as a Show, letting you save/recall all Snapshots for different live events. Channel Safes allow a specified channel not to change when a new Snapshot is recalled. Snapshots and Shows are stored and recalled from a USB drive (sold separately).

USB Playback: The Soundcraft mixer features a front-panel USB-A port for 2-channel or multi-track audio playback. This can be used for playing backing tracks during a live performance, or for background music between sets.
