Dzien dobry, dziś do sprzedania mam kartę dźwiękową do Raspberry Pi Audio Injector Zero.

Karta jest nieużywana.

Poniżej parametry:

Features:
Raspberry Pi 40 pin standard header (suits Pi 0, 2, 3, 4 & expected future versions)
Main soundcard with all input, output and mute codec lines broken out
Main soundcard with +-12V and phantom power lines provided
Main soundcard with GPIO lines broken out for preamplifier control
RIAA phono preamplifier (skin). Soundcard and preamplifier are sold separately post Kickstarter.
Preamplifier board can be changed for different ones with other features, such as our balanced XLR preamplifier and our RCA preamplifier.
We have future proofed the preamplifier connectors to allow all sorts of different designs to be made, for example microphone preamps, headphone amps.
Build your own preamplifier PCBs and attach them (implements the Audio Injector Analogue Breakout Standard v1)
Integrated into Linux (for Rasbian - Raspberry Pi) and the ALSA machine driver is easily ported to other Linux based embedded systems.

Specifications:
192 kHz sample rates, 24 bit audio words, using the cs4272 codec
Suitable preamplifiers available (check their pages here or on the shop).
Ships with a 40 pin header assembled, a second header slot on the sound card not assembled for you to use.
Isolation hardware (magnetic)
On the chip audio mixer to control the sound levels and features.
DC coupled - no AC coupling caps
Main sound card DAC Full Scale (FS) peak to peak output voltage : 4.8 V
Main sound card ADC FS peak to peak input voltage : 5.65 V
Main sound card closed loop gain (4.8/5.65) : -1.42 dB
FS voltage levels are accurate to the tolerances of the cs4272 codec (specified in their data sheet).
