IQaudIO AMP+ (Pi-DigiAMP+)

The IQaudIO Pi-DAC+ is simply stacked on top of the Raspberry Pi A+/B+/2/3 using the GPIO pins (no soldering necessary). The special feature of the Pi-DigiAMP+ allows a full HD (24-bit/192kHz) audio file experience and audio capability with up to 2x35w stereo output to speakers. The IQaudIO Pi-DAC+ is the perfect solution for HiFi systems and can be used as the basis of a retro radio restoration, as a boom box, as audio player for car solutions and much more. The Pi-DigiAMP+ uses GPIO22 as software controlled mute system and also offers hardware volume control (ALSA). The IQaudIO Pi-DAC+ chipset (TAS5756m) delivers an outstanding performance from a single HAT board. The Linux driver support is already implemented to Raspbian Linux.
Further pin-strips are already placed on the card to connect other hardware components.

Technical Details:

IQaudIO support with Max2Play

The Max2Play image supports exclusively the IQaudIO Pi-DigiAMP+ with additional features like:

• Rotary encoder for hardware volume control and autostart option on boot
• Volume Settings for Analogue Boost, Analogue Playback Boost and Master Volume for best performances
• Choose between 3 setups for your preferred use of the audioplayer
• IR-Control to set up a remote control for wireless operations
• Improved automatic WiFi Configuration when enabling WPS in the WiFi / LAN tab

Plug & Play with Max2Play especially for IQaudIO Pi-DigiAMP+ sound cards

Max2Play offers a browser-based administration interface for Raspberry Pi on a Linux basis. With Max2Play, applications (Max2Play extensions) can be installed and administrated on a minicomputer without any Linux knowledge. The controls can be accessed via smartphone, tablet or computer, without connecting a mouse or keyboard to the minicomputer.

The Max2Play image has been optimized for the IQaudIO Pi-DigiAMP+ and can be set up easily. It ensures the best support of the IQaudIO Pi-DigiAMP+ and Raspberry Pi combination. The IQaudIO Pi-DigiAMP+ can also easily be installed with the help of a Max2Play extension. The extension installs all necessary kernel drivers. After activating the sound card, it can be used by the audio players (e.g. Squeezelite or MPD) for sound output. The volume settings are then automatically set to the optimal levels.
