Raspberry Pi IQAudio DAC+ (DEV-17738)
DESCRIPTION
The IQaudIO Pi-DAC+ HAT Audio card for the Raspberry Pi delivers outstanding sonic performance and full-HD (24/192) audio capability with build-in hardware volume control through the standard Linux audio APIs (ALSA) using the Raspberry Pi’s I2S digital audio signals delivering much lower CPU usage and vastly improved audio quality vs. USB audio cards.
用於Raspberry Pi的IQaudIO Pi-DAC + HAT音頻卡具有出色的聲音性能和全高清（24/192）音頻功能，並通過使用Raspberry Pi的I2S數字音頻的標準Linux音頻API（ALSA）內置硬件音量控制與USB聲卡相比，該信號可提供更低的CPU使用率並大大改善了音頻質量。
The Pi-DAC+ corresponds to the Raspberry Pi Foundation's HAT specification, includes the HAT auto configure EEPROM, camera and display cut outs, mounting holes and form factor. It's designed to deliver the best audio performance from the Raspberry Pi B+/RPi2, fit within the Pi's form factor and provide additional access to many of the Pi B+'s 40way I/O signals. The Pi-DAC+’s Phono/RCA connectors have an integrated mounting hole bringing increased rigidity when used in an case / enclosure reducing the wear and tear on the Raspberry Pi’s headers due to flexing. This along with the Pi-DAC+’s HAT mounting holes, aligned to that of the Raspberry Pi's, delivers a rock solid pairing with no concern of the audio card becoming disconnected from the Raspberry Pi during long term use.
Pi-DAC +符合Raspberry Pi Foundation的HAT規範，包括HAT自動配置EEPROM，攝像頭和顯示器切口，安裝孔和外形尺寸。它旨在提供Raspberry Pi B + / RPi2的最佳音頻性能，適合Pi的尺寸，並提供對Pi B +的許多40way I / O信號的額外訪問。Pi-DAC +的Phono / RCA連接器具有集成的安裝孔，在用於箱體/機箱中時可提高剛性，從而減少了因彎曲而引起的Raspberry Pi接頭的磨損。這與Pi-DAC +的HAT安裝孔（與Raspberry Pi的對齊）對齊，可實現堅固的配對，而無需擔心在長期使用中聲卡會與Raspberry Pi斷開連接。
The Pi-DAC+ provides the support for additional pin-headers providing increased flexibility to your project and easy connection to our other products. Exposed signals include Audio L+R out, amp-mute, headphone out, and the majority of the Raspberry Pi's 40way connector. Please note that The Pi-DAC+ uses GPIO22 as amp-mute.
Pi-DAC +提供了對其他引腳連接器的支持，從而為您的項目提供了更大的靈活性，並易於連接到我們的其他產品。暴露的信號包括音頻L + R輸出，放大器靜音，耳機輸出以及Raspberry Pi 40way連接器的大部分。請注意，Pi-DAC +使用GPIO22作為放大器靜音。
Use raw Linux, Volumio, Raspbmc, RuneAudio, MDP or similar and listen to internet radio, your own digital music library, or streaming music services – all in magnificent audio quality. The IQaudIO Pi-DAC+ easily supports 24-bit / 192kHz file formats but is equally at home with lower quality MP3s bringing your music alive sonically.
使用原始的Linux，Volumio，Raspbmc，RuneAudio，MDP或類似產品，並收聽互聯網廣播，自己的數字音樂庫或流式音樂服務-所有這些都具有出色的音頻質量。IQaudIO Pi-DAC +輕鬆支持24位/ 192kHz文件格式，但在質量較低的MP3上同樣可以在家中使您的音樂栩栩如生。
