The AudioworX Starter Kit consists of hardware and software components that need to be set up for functioning as a target amplifier which can interface with GTT to provide a comprehensive experience of AudioworX. The following sections cover the hardware and software components required and provide steps to install software pre-requisites.
Following is a list of hardware components required to setup the Starter Kit:
- Raspberry Pi 5 8 GB RAM variant (low-cost pocket-sized Linux computer).
- 27 W power adapter for the Raspberry Pi (USB Type-C).
- Micro SD Card with custom 64-bit Raspbian OS image (plugged into the Raspberry Pi 5).
- Sound Blaster X4 USB Audio Interface for multichannel analog audio input and output.
- JBL DSP 4086 power amplifier with 6 input channels (for passive speaker setups only).
- 12V 20A SMPS power supply for the amplifier (for passive speaker setups only).
- Ethernet cable for connecting the Raspberry Pi 5 to the PC (recommended)
- Speakers for audio output (6 passive speakers or 8 active speakers).
- A stereo analog audio source (PC or mobile phone with audio out).
- Windows PC
The JBL DSP-4086 amplifier and the 12V 20A power supply are only required if the speakers being used for audio playback are passive. For active speaker setups (speakers with their own power), the Creative Sound Blaster X4 can be directly connected without the JBL amplifier. Refer to Hardware Components Setup for more details.
Required Software Applications
Following is a list of software applications to be installed on a Windows PC to operate the Starter Kit:
Download and install the above-mentioned pre-requisites on a Windows 10 or 11 PC. For steps on how to install GTT and its pre-requisites, refer to open Installation and Licensing guide.
The GTT installation includes the Starter Kit Utility tool, a Python command-line application that provides the ability to remotely operate the Starter Kit hardware over the network, for actions like verifying hardware connections, audio device configuration, resetting the AWX Amp application running on the Raspberry Pi, rebooting the Raspberry Pi, etc. For more details, refer to Starter Kit Utility Tool.
This tool is installed in the following directory (default GTT installation folder):
C:\Program Files\Harman\HarmanAudioworX\StarterKit\StarterKitUtility
To install the pre-requisite python packages:
- Go to the “StarterKitUtility” directory, type “cmd” in the address bar, followed by the enter key to open a Command Prompt window.
- Run the following command to install the python pre-requisites as shown below.
python3 -m pip install -r requirements.txt
