SYSTEM REQUIREMENTS

MacOS 10.12, 10.13, 10.14 or 10.15 (latest update). Intel Core i5, 4 GB RAM (6 GB recommended).
Windows 10 (latest Service Pack), Intel Core i5 or equivalent CPU, 4 GB RAM (6 GB recommended).
USB 2.0 or higher (cable provided).
Graphics Card which supports Open GL 2.1 or higher.

GETTING STARTED

The Livejack Lite has a single USB 2.0 Type C port (on the rear panel): connect it to your computer using the USB cable provided. Note that Livejack Lite is a USB 2.0 device, and thus the USB connection requires a USB 2.0+ compliant port on your computer.
Livejack Lite gets its power from your computer via the USB connection: there is no need for a separate power supply. We recommend that when using it with a laptop, the laptop should be powered using its AC adaptor, as otherwise the battery will run down faster than when powering the laptop alone.

Mac Users:

Connect the Livejack Lite to your computer using the USB cable provided.
Your OS should automatically switch the computer’s default audio inputs and outputs to the Donner Livejack Usb Audio. To verify this, go to System Preferences> Sound, and ensure that the input and output are set to Livejack Lite. For more detailed setup options on a Mac, open Applications> Utilities> Audio MIDI Setup.

Win Users

Click www.donnerdeal.com/pages/download or Scan the QR code to download the Donner Livejack ASIO USB Audio Drive.
Follow the instruction to setup the ASIO Drive, the installer will take you through each step of the installation process.
Notes: It is recommended that you temporarily disable or turn off any anti-virus programs you have running to prevent installation issues.
After installed, connect the Livejack Lite to your computer using the USB cable provided.
Your OS should automatically switch the computer’s default audio inputs and outputs to be the Livejack Lite. To verify this, right click on the Sound icon on the taskbar and select Sound Settings, and set the Livejack Audio Interface as the Input and Output Device.
When ASIO Drive is launched, you will see the Launch window. From this window, you can manage all the ASIO driver settings.

Sample Rate: Changes the sample rate. You can set the sample rate to 44100, 48000, 88200, 96000, 176400, or 19200 kHz. A higher sample rate will increase the file size and the amount of system resources necessary to process the audio.
Buffer: Adjusts the buffer size. From this menu, you can set the buffer size. Lowering the buffer size will lower latency. 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.
IN1 &1N2: Adjusts the input volume in digital audio stream.
OUTPUT: Adjusts the output volume in digital audio stream.

AUDIO SETUP IN DAW

After following the procedure described above, you can start using your Livejack Lite with the DAW of your choice. Operating instructions for DAW are beyond the scope of this User Guide, but most kind of DAW applications include a full set of Help files.
Please note -your DAW may not automatically select the Livejack as its default 110 device. In this case, you must manually select Donner

Livejack Usb Audio as the driver on your DA W’s Audio Setup page. Please refer to your DA W’s documentation if you are unsure where to select the AS/0 or Core Audio driver. The example below shows the correct configuration in the Logic Pro X Preferences panel. DONNER EC1344 Livejack Lite 2 In 2 Out USB
Audio Interfaces FIG 6

Once the Livejack Lite is set as the preferred Audio Device in your DAW, its inputs and outputs will appear in your DAW’s Audio 110 preferences. Depending on your DAW, you may need to enable certain inputs or outputs before use. The two examples below show two Inputs and two outputs enabled in the Logic Pro X Audio Preferences.

Note: The speed of your processor, amount of RAM, and capacity, size, and speed of your hard drives will greatly affect the overall performance of your recording system. A faster processor and more RAM can reduce signal latency (delay) and improve overall performance.

SETUP

Connection
This setup illustrates a typical configuration for recording using DAW software on your Mac or PC. In this case, you would record vocals through Input 1 and guitar through Input 2 into your recording application, while monitoring the playback via headphones.
Livejack Lite inputs are on the front panel: Input 1 uses a standard 3-pin XLR socket. and is configured to work with microphones of most types; you will probably have a male XLR connector on the end of your mic cable.
If you are using a “studio” condenser (capacitor) microphone designed to operate on 48-volt phantom power, press the 48V button.
Input 2 uses a 1/ 4″ (6.35 mm) jack socket which is 2-pole when in instrument mode and 3-pole when used as a mono line input. It can accept signals from an electric or electroacoustic guitar or bass, a keyboard, and most other types of audio equipment. Set the INST switch ON if you are connecting a musical instrument, e.g., a guitar in the example, using an ordinary 2-pole (TS) guitar jack. Set the INST switch to OFF if you are connecting a line level source such as a keyboard, synthesizer or the balanced output of an external audio mixer via a 3-pole (TRS) jack. Note the jack socket accepts both TRS and TS types of jack plug.

Monitoring
You will frequently hear the term “latency” used in connection with digital audio systems. In the case of the simple DAW recording application described above, latency will be the time it takes for your input signals to pass through your computer and audio software. Latency can be a problem for a performer who wishes to record while monitoring their input signals.
With a “Direct Monitoring” option, it can overcome this problem. Setting the front panel DIRECT MONITOR switch to ON will route your input signals directly to the Livejack Ute’s headphone and main monitor outputs. This enables you to hear yourself with zero latency. Your inputs will be summed to mono. Note that the input signals to your computer are not affected in any way by the use of Direct Monitor.
When Direct Monitoring is set to ON, ensure that your recording software is not set to route its input (what you are currently recording) to its output. If it is, you will hear yourself “twice”, with one signal audibly delayed as an echo.
Monitoring with DIRECT MONITOR set to OFF can be useful when using an FX plug- in to your DAW to create a stereo effect which contributes to the live performance. In this way, you will be able to hear exactly what is being recorded, complete with the FX. However, some latency may result, the amount depending on the DAW’s buffer size and processing power of the computer.
