- Page 2 IQaudIO User Guide This document covers the installation, software configuration and usage of IQaudIO audio cards for the Raspberry Pi. If you would like to see additional information within this document please email us at info@iqaudio.com For those who simply need the /boot/config.txt details —>...

- Page 4 1) Getting Started Thank you for choosing an IQaudIO sound card. Next you need to play music, but first you may need to configure the Raspberry Pi’s Linux OS. You will find several audio applications with pre-configured Micro SD Card images on we also include quickest images which will help you check that you www.iqaudio.com/downloads...
- Page 5 Pi into a Roon Certified end-point. The Pi is then controlled form the RoonLabs PC/ Mac application which connects to and plays music through the IQaudIO sound card. This is again similar with the Shairport-sync utility - it turns the Pi into a Apple Airport compatible speaker, music and volume is then controlled from your iPad / iPhone, or iTunes.
- Page 6 How do I install software on the Pi? The Raspberry Pi loads its software from the micro-SD card. Most audio applications assume they are the only thing running on the Pi so most require a dedicated SD card. The applications are normally distributed as a compressed .img file (likely a .zip or .gz file) and this .img file will need to be written to the Pi’s SD card to allow the Pi to boot.
- Page 7 2) The Pi-DAC+ The Pi-DAC+ is a fully HAT compliant add-on accessory for the Raspberry Pi A+/B+/Pi2/Rpi3. The Pi-DAC+ takes the digital audio signals (I2S) from the Raspberry Pi and through the onboard Texas Instruments PCM5122 DAC delivers variable output (hardware volume control) analog audio to the Pi-DAC+’s Phono connectors.
- Page 8 3) The Pi-DigiAMP+ The Pi-DigiAMP+ is a fully HAT compliant add-on accessory for the Raspberry Pi. The Pi-DigiAMP+ takes the digital audio signals (I2S) from the Raspberry Pi and through the onboard Texas Instruments TAS5756M PowerDAC delivers direct connection to stereo speakers at up to 2x35w with variable output.
- Page 9 4) The Pi-AMP+ The Pi-AMP+ is an add-on accessory for the Pi-DAC+ and Raspberry Pi. The Pi-AMP+ takes the variable output analog audio from the Pi-DAC+ and through the onboard Texas Instruments TPA3118D2 Class D amplifier delivers audio to the Pi-AMP+’s speaker terminals delivering up to 2x35w@19v input.
- Page 10 The Pi-DAC PRO users the Texas Instruments PCM5242 to deliver outstanding Signal to Noise Ration and supports Balanced / Differential out in parallel to Phono / RCA line level output. It also includes the IQaudIO Headphone amp. The Pi-DAC PRO can be connected to the Raspberry Pi A+/B+/RPi2 or RPi3’s 40way pin header without any additional soldering.
- Page 11 6) Pi-Digi+ The Pi-Digi+ is a fully HAT compliant add-on accessory for the Raspberry Pi. The Pi-Digi+ takes the digital audio signals (I2S) from the Raspberry Pi and through the onboard Wolfson / Cirus Logic WM8804 delivers Optical TOSLINK and isolated electrical SPDIF connection to an external DAC.
- Page 12 7) The Pi-DACZero / DACZeroHeadphone The Pi-DACZero is a smaller version of the IQaudIO Pi-DAC+ which is designed to be used with the Raspberry Pi-Zero. The Pi-DACZero delivers audio Line Out and uses the same Linux drivers as the Pi-DAC+.
- Page 13 8) Connecting the Pi-DAC+ to your Raspberry Pi WARNING: PLEASE ENSURE ALL CABLES ARE DISCONNECTED FROM THE Pi-DAC+ AND THE RASPBERRY PI BEFORE ATTEMPTING THIS PROCEDURE. The Pi-DAC+ can be connected to the Raspberry Pi’s 40way pin header without any additional soldering.
- Page 14 Once the Pi-DAC+ has been fitted the remaining screws can be tightened (finger tight please) as required. If you are using the Pi-CASE+ then replace the 4x screws beneath the Pi with the 4x 5mm PCB standoffs provided with the Pi-CASE+ v27 10-Sept–2017...
- Page 15 Apply power to your Raspberry Pi in the normal way. You should see that the Raspberry Pi and the Pi-DAC+ both have power LEDs – this indicates that the power is successfully being applied to the Pi-DAC+. You can now remove power and reconnect any necessary peripherals. v27 10-Sept–2017...
- Page 16 9) Connecting the Pi-DigiAMP+ to your Raspberry Pi WARNING: PLEASE ENSURE ALL CABLES ARE DISCONNECTED FROM THE Pi-DigiAMP+ AND THE RASPBERRY PI BEFORE ATTEMPTING THIS PROCEDURE. The Pi-DigiAMP+ can be connected to the Raspberry Pi’s 40way pin header without any additional soldering.

- Page 18 DO NOT APPLY POWER TO YOUR RASPBERRY PI VIA THE PI’s MICRO USB SOCKET. The Pi/Pi-DigiAMP+ combination MUST be powered via the Pi-DigiAMP+, not the Raspberry Pi. Once you are happy with that the Raspberry Pi and Pi-DigiAMP+ are connected correctly you are nearly ready to apply power.

- Page 20 10)Connecting the Pi-AMP+ to your Pi-DAC+ WARNING: ENSURE YOU HAVE DISCONNECTED ALL POWER BEFORE ATTEMPTING THIS PROCEDURE The Pi-AMP+ connects to the Pi-DAC+ through both Pi-DAC+’s two pin headers (the 2x4 audio pin header, and the 2x5 power header). NOTE: Older Pi-DAC+ may not have the 2x5 power header fitted. Please see Section 10 for details on how to solder this to the Pi-DAC+ before continuing.
- Page 21 The male/female spacers should replace the 4 screws (these should be retained) previously used to secure the Pi-DAC+ to the Raspberry Pi. Once the Pi-AMP+ has been fitted the remaining screws (from the Pi-DAC+) can be tightened (finger tight is fine) as required to secure the full PCB stack. v27 10-Sept–2017...

- Page 24 11)Building the Raspberry Pi and IQaudIO sound cards into your Pi-CASE+ The following may prove helpful when building your Raspberry Pi and IQaudIO sounds card into the appropriate Pi-CASE+. All acrylic CASE+ installations follow the same process: • If there is a protective film applied to either side of your acrylic, remove it now.
