New Raspberry Pi Sound Cards: Pi-DAC+, Pi-DigiAmp+ and Pi-DAC+ Pro

New and optimised versions of IQaudIO’s HAT sound cards are now available at Max2Play! These three sound cards take up even less space mounted on the Raspberry Pi and were also improved by a few adjustments to the board.

Among the most important innovations is the 40-Pin GPIO header on top of the board, with which you can mount buttons, sensors and other accessories, as well as the now pre-programmed EEPRO-Memory, to configure the sound card quickly and easily. Furthermore, IQaudIO uses the usual high-quality audio components, designed and manufactured directly in the United Kingdom.

Pi-DAC+

The new version of the IQaudIO Pi-DAC+ (Rev4) comes with pre-programmed EEPRO-Memory for fast Linux configuration. Unlike its predecessor, all GPIO pins remain accessible when mounted on the Raspberry Pi. Therefore no soldering is required.

• Raspberry Pi HAT (A+/B+/2/3/3B+) compliant accessory
• Pre-programmed EEPROM for auto configuration
• Full-HD Linux audio – up to 24-bit/192kHz playback
• Integrated hardware volume control (via ALSA), full 2v RMS
• Built-in high-quality audio headphone amplifier (TI TPA6133A)
• Class leading audio; 112db SNR, and -93db THD
• Audiophile TI Burr Brown 32-bit/384kHz DAC (TI PCM5122)
• Advanced ESD protection
• Digital I2S audio signals
• Raspberry Pi powered, no external power requirements
• Industry standard audio quality Phono/RCA connectors

Pi-DAC+ Pro

The Pi-DAC+ Pro has also been redesigned. Unlike the Pi-DAC+, IQaudIO installed the TI PCM5242 and a mini DSP here. In addition, the Pro achieves a slightly better signal-noise-ratio of 114dB and a total harmonic distortion of -94dB.

• Raspberry Pi HAT (A+/B+/2/3/3B+) compliant accessory

• Full-HD audio – up to 24-bit/192kHz playback
• Integrated hardware volume control (via ALSA)
• Built-in high-quality audio headphone amplifier (TI TPA6133A)
• Class leading audio; 114db SNR, and -94db THD
• Audiophile TI Burr Brown 32-bit/384kHz DAC (TI PCM5242)
• Advanced ESD protection
• Digital I2S audio signals
• Raspberry Pi-powered, no external power requirements
• Industry standard audio quality Phono/RCA connectors
• Balanced output (XLR) exposed on PCB for soldering
• Built-in mini DSP

Pi-DigiAmp+

Like the two DACs, the new version of the IQaudIO Pi-DigiAmp+ also comes with pre-programmed EEPRO-Memory and additional GPIO pins. The Pi-DigiAmp+ delivers up to 2x35W and supports input voltages up to 24V. It also added new, modular terminals for even more flexibility in its applications.

• Full-HD audio – up to 24-bit/192kHz playback
• Up to 2x35w of crystal clear amplification
• Pre-programmed EEPROM for auto configuration
• Integrated hardware volume control (via ALSA)
• Powers the Raspberry Pi from the Pi-DigiAMP+ power input
• Linux driver support already delivered within Raspbian
• Advanced ESD protection
• Uses the digital I2S audio signals
• Supports up to 24V input
• Delivers full 2.5A to the Pi, supports screens & USB devices in parallel
• Full GPIO access with no soldering required
