Audio Injector Pro with Phono Pre-Amp Skin Brings High-Definition Audio to the Raspberry Pi
Designed with a user-swappable modular two-board layout, the Audio Injector Pro comes bundled with a phono pre-amp stage.
Audio specialist Flatmax Studios is back on Kickstarter with an upgraded high-quality soundcard add-on for the Raspberry Pi, this time bringing a phono pre-amp along for the ride: the Audio Injector Pro.
"Following on from our success with the [Audio Injector] Isolated soundcard we realized that some people want super high definition audio at a lower cost," Flatmax's Matthew Flax explains. "Some members of the Audio Injector community have also said they were interested in a phono analog skin. Here are our latest technologies, the Audio Injector Pro soundcard with analog phono preamplifier."
Designed to sit atop a Raspberry Pi or compatible single-board computer and connect via the general-purpose input/output (GPIO) header, the Audio Injector Pro is a bundle of two boards. The main board is a high-definition soundcard, based on a CS4272 codec offering 24-bit resolution at a 192kHz sample rate. Relays are added to the board as "muting circuits," preventing pops and noise during reboots, while the phono pre-amplifier stage is connected as an add-on board dubbed a "Skin."
While the phono pre-amp is bundled with the card for the Kickstarter campaign, Flax has indicated the two will be sold separately post-crowdfunding — and that the soundcard is compatible with the company's other Skins, including a balanced XLR pre-amp and an RCA pre-amp. Enthusiasts can even build their own, using the company's open Audio Injector Analog Breakout Standard specification.
The campaign is now live on Kickstarter, with rewards starting at AU$55 (around $40) for a single Audio Injector Pro with bundled phono pre-amp Skin.
