Universal Control

Universal Control is both a driver-management utility and software control interface for your Quantum Interface. Universal Control provides the following:

• Hardware Control. All of Quantum’s front panel hardware controls can be controlled using Universal Control, facilitating easy hardware manipulation even if Quantum is installed in a location out of reach of the computer operator.
• Low-Latency Monitoring. Using Universal Control eliminates the latency associated with DAW I/O buffering that makes monitoring problematic for the performer. By removing the DAW’s software input monitoring feature from the monitoring signal flow altogether, the need to adjust I/O buffer sizes and latency is no longer an issue.
• Send / Cue Buses. Universal Control has stereo aux buses, with independent send levels per input.
• Configuration Management (Scenes). Universal Control configurations can be saved and loaded to / from disk as Scenes, for convenient and unlimited session management.

Universal Control has two main components: the Launcher and the Mixer. We’ll go into more detail about each in the sections below.
2.1 Universal Control Launcher
Universal Control contains driver support, software control, monitor mixing, and firmware management for PreSonus hardware. After opening Universal Control, you will see the Launch window. From this window, you can manage all the driver settings.

• Sample Rate. Changes Sample Rate. You can set the sample rate to 44.1, 48, 88.2, 96, 176.4, or 192 kHz.
  A higher sample rate will increase the fidelity of the recording, but this will also increase the file size and the amount of system resources necessary to process the audio.

• Clock Source. Sets the Digital Clock Source. From this menu, you can set the Clock Source for your Quantum HD interface. Internal, External S/PDIF, External ADAT, or Wordclock (Quantum HD 8 Only).

• Block Size (Windows only). Sets the Buffer Size. From this menu, you can set the Buffer Size for your Quantum HD interface from 16 to 2048 samples.

  • Lowering the buffer size will reduce the overall latency. However, this will also increase performance demands on your computer. In general, you will want to set the buffer size as low as your system can safely support. If you begin to hear pops, clicks or distortion in your audio path, try raising the buffer size.

• Firmware. Displays the current firmware version.

• Input Format. Details your device Input channels and bitrate.

• Output Format. Details your device output channels and bitrate.

• Serial Number. Displays your Quantum serial number.

2.1.1 Launching the Universal Control Mixer
Universal Control’s Mixer can be launched from the Universal Control application (Launcher).

1. Open Universal Control.
2. From the Universal Control Launcher, click on the product card for the Quantum ES or HD Control Panel (mixer).
3. The Universal Control Mixer will open in another window.

2.1.2 Quitting Universal Control

• Settings Panel. Shows / Hides the Settings panel (replaces the mixer). See section 2.2.8 Settings Panel for more information about how to use this feature.

2.2.2 Channel Overview
Channel Inputs
Each channel input strip controls a corresponding Quantum hardware input or virtual input. The output of all channel inputs are always routed to the Main 1 and 2 outputs (except when muted). Inputs can be optionally routed to other outputs via Sends and the FlexChannel controls. Universal Control channel inputs are essentially the same for all inputs; however, there are some differences among the analog and digital inputs as noted below. Channel Input Controls

• High Pass Filter (HPF). Engages / disengages a HPF at 80 Hz with a slope of 12 dB per octave.
• 48V. Engages / disengages 48V phantom power for use with condenser microphones.
• Autogain. Automatically sets the gain for the selected channel.
• Pad (Quantum HD only). Cycles through -20 dB or no pad attenuation (default). Pad does not affect the Line or Instrument inputs.
• Preamp Gain Level. Use this control to set the gain (0 dB to +75 dB) for your microphone or instrument.

2.3 Using Universal Control’s Mixer
2.3.1 Loopback
Loopback audio is the industry term for routing audio from one application to another. Applications that use audio interfaces, like your Quantum interface, are designed to receive audio from one audio device and send audio to one audio device. This means that most applications can only send to and receive from an audio interface, but not from other applications. This can present a challenge in certain situations.
Fortunately, Quantum ES and HD audio interfaces allow you to take audio from any of Universal Control’s mixer inputs (mics, guitars, computer audio, etc.) and send the combined audio to another application for the purpose of recording or live streaming.

2.3.2 How to Use Loopback
If you wish to use the Loopback feature, follow the directions below:

1. Make sure that your Quantum ES or HD is selected as the Windows or macOS playback device.

2. In your DAW or software application, choose the channel input labeled Loopback 1 or Loopback 2.
   Any audio sent to Loopback 1 or 2 will be available as a virtual input in your DAW or other software applications (not all software applications support multichannel inputs).
   Note: Loopback inputs are disabled at sample rates of 176.4 and 192 kHz.

3. In Universal Control’s mixer window, adjust the send level to whichever Loopback send you’ve selected in Studio One.
   • Loopback 1 Send Level. Adjust the amount of audio you would like to send to Loopback stream 1.
   • Loopback 2 Send Level. Adjust the amount of audio you would like to send to Loopback stream 2.

4. After adjusting the Loopback send level, you’ll notice metering levels appear within the DAW or software application channel you’ve set up. Once metering appears, you are ready to start recording audio.
   WARNING: Make sure that the channel in your DAW is muted before you record enable to avoid feedback loops.

2.3.3 Quantum Multichannel
Multichannel is a hardware and software operating mode that can be configured using Universal Control.
Quantum ES 4, HD 2 and HD 8 interfaces can be used as an all-in-one monitoring hub for some multichannel formats (depending on the amount of analog outs per device).
When a multichannel mode is selected, the knob will control all corresponding speaker volume at once. For more information about each of the Multichannel options, review the list below:

• 1 – 2 (All models). The default Main Encoder mode. The knob will control the output volume for Main Outputs 1 and 2.
• 1 – 4 (Quantum HD 2 and HD 8 only). The knob will control the output volume for Outputs 1, 2, 3, and 4 all at the same time.
• 1 – 6 (Quantum HD 8 only). The knob will control the output volume for Outputs 1, 2, 3, 4, 5, and 6 all at the same time.
• 1 – 8 (Quantum HD 8 only). The knob will control the output volume for Outputs 1, 2, 3, 4, 5, 6, 7, and 8 all at the same time.
• All (Quantum ES 4, HD 2, and HD 8 only). The knob will control the output volume for all outputs at the same time.
• None. Knob control is disabled and unity audio will be sent out of all outputs.
  WARNING: Full scale audio will be sent out of Main Outputs 1 and 2. Main Outputs 1 and 2 will be muted when this mode is selected to avoid damaging speakers or other equipment.

Using Your Quantum USB

3.1 As an Audio Interface
Quantum ES and HD function like other audio interfaces when used without the Universal Control application installed. Quantum ES and HD’s class-compliant (macOS) and WDM drivers (Windows) enable it to be used for computer audio I/O routing with any compliant software with some limitations.
3.1.1 Standalone Use (HD 8 ADAT Preamp Expansion)
The Quantum HD 8 can be used to add mic pres to another Quantum HD running in audio interface mode (with Universal Control installed) or a third party audio interface that supports ADAT optical inputs as well as S/MUX and its variants.
To use a second or third Quantum HD as a standalone preamp through ADAT, access the secondary or tertiary Quantum HD’s Global Settings when not connected to a computer and set the Standalone mode to “ADAT Pre.” By default, this mode is set to “Mixer.”
3.2 With Universal Control
Quantum ES or HD and Universal Control can be used without a DAW or any other software. Using Universal Control without a DAW provides access to all Quantum ES or HD functionality and simplifies the use of Quantum ES or HD’s digital mixing and monitoring when a DAW is not needed.
3.2.1 Quantum I/O Driver Names
Each Quantum input and output has a channel number and name provided by the Quantum ES or HD drivers on macOS and Windows. If an audio software application can access Core Audio / ASIO devices directly, it may be possible to designate specific inputs and/or outputs within the application.
3.2.2 Universal Control Settings that are Retained after Power Cycle
All currently active Main Mix settings (channel volume level, pan position, solo, mute, and stereo link) and monitor settings (main and headphone output levels) are saved to internal firmware before Quantum ES or HD are powered down, and recalled when power is reapplied.
Note: Changes are not saved instantaneously. Please allow up to 10 seconds for the settings to be saved to the device before powering down.
3.3 With a DAW (without Universal Control)
When used with a DAW but without the Universal Control application, the DAW controls all signal I/O routing and software monitoring.
3.3.1 Monitoring with the DAW
The primary function of Universal Control is monitoring Quantum’s inputs during live performance. When software monitoring is enabled in the DAW, Universal Control input monitoring must be disabled to eliminate doubled signals.
Make sure to disable input monitoring in Universal Control when software monitoring via the DAW. If Universal Control’s input monitoring isn’t disabled (muted channel, fader down, or bypassed mixer), phasing and/or doubling of the monitored signal(s) will occur because the input signal is being heard twice – first from the low-latency DSP mix (Universal Control) and shortly thereafter from the higher latency software mix (DAW).
3.3.2 How to disable input monitoring in Universal Control
To disable input monitoring in Universal Control when using software monitoring in the DAW, open Universal Control and mute all input channels within Universal Control or activate “Bypass Mixer” in the Settings.
Universal Control may then be closed.
Using a DAW without Universal Control is a typical workflow during mixdown, where low-latency monitoring is not required and buffering latency is not an issue because the tracks are already recorded. When recording new tracks, the DAW and Universal Control workflow (as described in the following section) is recommended.
In this scenario, Quantum functions as an audio interface. The DAW accesses and routes Quantum’s audio interface I/O via the device drivers. Audio I/O latency is determined by the I/O Buffer Size setting.
3.4 With a DAW (with Universal Control)
Universal Control is used concurrently with a DAW when low-latency monitoring is desired. This workflow completely eliminates the I/O buffering latencies associated with software monitoring. In this scenario, Universal Control is used to control all input monitoring when recording, and the DAW’s software monitoring feature should be disabled.
3.4.1 Software Monitoring versus Hardware Monitoring
Software monitoring (listening to live inputs via the DAW mixer) has discernible latency due to audio interface I/O buffering. Hardware monitoring via an audio interface’s internal DSP mixer (e.g., the Universal Control application) does not have discernible latency because the live audio is internally routed directly from the inputs to the outputs without DAW I/O buffering.
3.4.2 Monitoring with Universal Control
The primary function of Universal Control is monitoring of Quantum inputs during live performance. When used with a DAW, Universal Control is used as a monitor mixer that functions separately from the DAW’s software monitoring mixer.
Make sure to disable Software Monitoring in the DAW when using Universal Control. When Universal Control is used for live input monitoring with a DAW, the DAW’s software monitoring feature should be disabled. If it isn’t, phasing and/or doubling of the monitored signal(s) will occur because the input signal is being heard twice – first from the low-latency DSP mix (Universal Control) and shortly thereafter from the higher latency software mix (DAW).
3.5 Loopback
Quantum’s device drivers carry virtual (software only) input and output channels in addition to those directly associated with the hardware inputs and outputs. Loopback facilitates highly flexible signal routing via the DAW, without needing to reach behind the gear rack for manual cable patching. Additionally, since the loopback audio streams are in the digital domain, a pristine audio signal path is maintained without requiring additional A/D – D/A conversions.
Loopback sends enable any input to be routed directly into Universal Control’s FlexChannel (see the “How to Use Loopback” section in this manual for more information).
3.6 Device Reset
If you encounter a problem with your Quantum and you need to reset the device, you can reset to the default device settings or revert to a previous firmware.
Default Device Settings
If necessary, you can restore the default mixer (preamp gain, output levels, etc.) and system settings (speaker switching modes, headphone mix sources, etc).
To restore the default system settings:

1. In Universal Control, navigate to Settings (gear icon)
2. Press the “Factory Reset” button
3. A confirmation box will appear
4. Select “Reset” to confirm or “Cancel” to cancel the reset

Revert to Previous Firmware
To revert to a previous firmware:

1. Uninstall the current version of Universal Control
2. Install the version of Universal Control that has the previous firmware
3. With the Quantum powered on, open Universal Control and click “Update Firmware”
4. A notification will say that your firmware is up-to-date and to update anyways
5. Select “Update anyways” and follow through the process

Note: If Quantum ES or HD ever becomes unresponsive, press and hold the knob while powering on to enter firmware recovery mode.

Quantum Control from Studio One

Your Quantum ES or HD interface can be controlled directly from Studio One (only compatible with version 6.6.1 or higher). After configuring the inputs and outputs of your interface within Studio One, you’ll have easy control over various channel parameters, including channel Preamp Gain, Phantom Power, High Pass Filter, Auto Gain and Pad (HD only). To set up your Quantum Interface in Studio One, follow the directions below.
Once all cable connections are made and you have updated the Quantum’s firmware:

1. Launch Studio One.
2. Navigate to Studio One/Options/Audio Setup/Audio Device (macOS: Preferences/Audio Setup/Audio Device) to open the Audio Device settings window.
3. Select Quantum as both the Playback and Recording device.
4. Configure any other Audio Device or Processing settings as desired.
5. Click OK.

4.1 I/O Setup
Before creating your first song, it’s recommended that you first configure your Quantum Interface for input and output routing in Studio One.
To route Inputs and Outputs, go to Studio One Preferences, then select “Audio Setup”. In the bottom left corner, select “Song Setup” to enter the Audio I/O Setup tab.
4.1.1 Assigning Hardware I/O to Software I/O Channels
Hardware inputs and outputs are assigned to software I/O channels in a matrix router, which is a visual representation of the routing. Software channels (mono and stereo) are each given a horizontal row, and hardware inputs and outputs are given vertical columns. The points at which these rows and columns intersect represent potential connections, or routes, between the hardware I/O and software I/O channels. By default, Studio One creates three Input Channels: one stereo and two mono. These channels are labeled Input L+R (stereo), Input L (mono), and Input R (mono). By default, the stereo Input Channel receives input from the first stereo hardware input pair of your selected audio device. The two mono Channels receive input from the same stereo hardware input pair. The Output Channel is labeled Main Out (stereo) and is routed by default to the first stereo hardware output pair of your selected audio device.
To create a route between software I/O channels and hardware I/O, click on the empty square at the intersection of the desired hardware input or output and the software channel input or output. A colored square appears with an M, L, or R label, indicating whether the route is a mono route (M) or the left or right side of a stereo route (L or R).
Note: At higher sample rates, the number of available ADAT Inputs and Outputs are reduced for each port.
At 88.2/96 kHz, only ADAT channels 1–8 are available, and all digital is disabled at sample rates higher than 96 kHz. Unavailable ADAT channels are indicated in italic text in the Input, Output, Bus, and Insert pages of the I/O Setup.
Quantum Input Setup
From the Inputs tab, you can enable any or all of the inputs on your PreSonus Quantum audio interface that you’d like to have available. Use the “Add” button options below the matrix to add new inputs. Quantum Output Setup
To edit the output routing, click onto the “Outputs” tab and add outputs using the Add buttons below the matrix router.

4.2 Default Device I/O Setup
We recommend that you create a default Audio I/O Setup that can be a starting point for all new Songs. This lets you immediately begin working on your new Song, with little or no preliminary setup.
To do so, create software I/O channels for all of your audio device’s commonly used inputs and outputs and name them appropriately. Then, click on the “Make Default” button in the Audio I/O Setup menu, and a popup window appears to confirm that you wish to make the current I/O setup the default for new Songs. Click “Yes”, and from that point forward, all new Songs will be created with this audio I/O setup.
You can always use the “Reset to Default” button to apply this configuration to a song.
4.3 Integrated Quantum Features
Studio One channel strips have integrated Quantum hardware controls built in when Quantum is selected as the Playback and Recording device in Studio One. To access these control features, open the “Mix” console view from the Studio One song page.
4.3.1 Channel Control Features
The channel control features will be embedded into the top of each channel.

• Preamp Gain Level. Use this control to set the gain (0 dB to +75 dB) for your microphone or instrument.
• Line Input Level. If a line level signal is connected through the TRS port of the combo jack, then preamp gain control switches to a Line Level control (-12 dB to +12 dB).
• Gain Value. Displays the absolute value for the current Gain. Double-click on the value to enter a specific value.
• High Pass Filter. Engages / disengages a HPF at 80 Hz with a slope of 12 dB per octave.
