XMOS Audio Interface - Quick Start Guide Version 1v0 Publication Date: 2009/12/17 Copyright © 2009 XMOS Ltd. All Rights Reserved. XMOS Audio Interface - Quick Start Guide (1v0) 1 2/8 XMOS Audio Interface The XMOS Audio Interface provides a complete multi-channel digital audio interface for XMOS Development Kits including the XS1-G Development Kit (XDK). The board provides six analog channels in and eight analog channels out with additional stereo S/PDIF, MIDI, instrument, microphone and headphone sockets. The analog channels are provided by an I2S CODEC. MIDI and S/PDIF are controlled directly from an attached XMOS device. The XAI Kit includes: XAI Audio Interface Board 64-way IDC Connector MIDI Expansion Cable Requirements: You require an XMOS development kit to use the XAI. Example software is available from XMOS providing a full reference design for your audio solutions. www.xmos.com XMOS Audio Interface - Quick Start Guide (1v0) 2 3/8 Getting Started Download and install the demonstration software from the XMOS website, according to your license agreement. To use a USB or AVB input, remove the back of the XDK and set DIP switches as required—see Figure 3. Replace the back cover. Connect your USB or AVB input device to the XDK. If you are using a USB device connect it to the USB port on the right-hand side of the XDK. If you are using an AVB device connect it to the Ethernet RJ45 socket to the right—see Figure 2 Connect the XAI to the XDK using the 64-way IDC cable supplied. Connect additional audio input and output devices to the XAI—see Figure 1 for details of input and output connectors. Plug-in the XDK using the 12V power supplies provided with the Kit. Switch on the XDK and wait for the LEDs to flash to indicate that the devices is initialised. The kit is now ready for use. www.xmos.com XMOS Audio Interface - Quick Start Guide (1v0) 3 4/8 XAI Connectors MIDI IN/OUT INSTRUMENT IN MIC IN AUDIO IN XDK 64-way IDC XAI AUDIO OUT HEADPHONE Select Input Switch COAX IN LINE OUT S/PDIF IN COAX OUT S/PDIF OUT Figure 1: XAI Connectors ~ If you are using the Coax or S/PDIF input connector, you must use the Select Input Switch to select the input device—left for Coax and right for S/PDIF.
