The JustBoom Amp HAT is a high-quality audio amplifier designed specifically for the Raspberry Pi. Digital-to-analog conversion is also included with the Amp HAT, so no external sound cards or DACs are required. Simply stack the plug-and-play add-on board (HAT) onto your Raspberry Pi A+, B+, 2B or the new 3B, and it will be ready to use immediately.
JustBoom designed the Amp HAT to be simple to install and use. With no soldering required and all the mounting hardware already provided, this product is suitable for both beginners and seasoned professionals alike. Just connect your Amp HAT to a set of passive speakers, and you can be up and running quickly, enjoying flawless, high-quality audio playback within minutes. Also included is an optional IR receiver to allow remote control operation of your Raspberry Pi Amplifier.
Featuring a Class-D power amplifier chip with built-in 192kHz/32-bit DAC, for a peak power output of 2 x 55 watts, the JustBoom Amp HAT outputs audio over two speaker cable connector blocks that accept anything up to 14 AWG cable and will provide crystal-clear audio to either 4 or 8 ohm passive speakers. The Amp HAT uses the I2S interface for its audio input, which reduces CPU load on the Raspberry Pi compared with USB solutions. It is also designed to back-power the Raspberry Pi over the 40-pin GPIO header, meaning you only need a single power supply for the entire system.
Note: To power this HAT you will need to pick up the Global Power Supply or possess one capable of powering the HAT.
Features:
- Full high-quality audio — 192kHz / 32-bit
- 2 x 55 watt peak output at 8 ohms (2 x 30 watt RMS)
- Includes both a DAC and power amplifier — just connect to your passive speakers
- Back-powers the Raspberry Pi over the GPIO (with full HAT-compliant protection) at 2.5A, so only one power supply is required for the whole system.
- Plug-and-play compatibility for ease of use
- Hardware and software volume control from your Raspberry Pi
- Onboard hardware jumpers for configuring mute and gain settings (jumpers could optionally be changed with switches)
- Mute/enable with GPIO22 (this can be overridden by using jumper J4)
- No soldering required
- Optional IR receiver included in package
- Unused GPIO pins still accessible via unpopulated extension header
- Full driver support in Raspbian / NOOBS
- Compatible with OSMC / Max2Play /RuneAudio / Volumio / Moode / PiCorePlayer / PiMusicBox / OpenELEC and others

JustBoom Amp HAT是專為Raspberry Pi設計的高品質音頻放大器。數字模擬轉換也包含在Amp HAT中，因此不需要外部聲卡或DAC。只需將即插即用附加板（HAT）堆疊到您的Raspberry Pi A +，B +，2B或新3B上即可立即使用。
JustBoom設計了Amp HAT，使其易於安裝和使用。無需焊接和所有安裝硬件已經提供，該產品適合初學者和經驗豐富的專業人士。只需將Amp HAT連接到一組無源揚聲器，您就可以快速啟動並運行，在幾分鐘內即可享受完美無瑕的高品質音頻播放。還包括一個可選的IR接收器，以便您可以遠程控制您的Raspberry Pi放大器的操作。
具有內置192kHz / 32位DAC的D類功率放大器芯片，峰值功率輸出為2 x 55瓦，JustBoom Amp HAT通過兩個揚聲器電纜連接器模塊輸出音頻，可接收高達14 AWG電纜並將為4或8歐姆無源揚聲器提供清晰的音頻。 Amp HAT使用I 2 S接口進行音頻輸入，與USB解決方案相比，可以降低Raspberry Pi的CPU負載。它還旨在通過40引腳GPIO接頭對Raspberry Pi進行後備電源，這意味著您只需要整個系統的單個電源。
注意：為HAT供電， 您將需要接通全球電源或擁有能夠為HAT供電的電源。
特徵：
- 全高品質的音頻 - 192kHz / 32位
- 8歐姆2 x 55瓦峰值輸出（2 x 30瓦RMS）
- 包括DAC和功率放大器 - 只需連接到被動揚聲器
- 以2.5A為背景，將Raspberry Pi覆蓋GPIO（具有完全HAT兼容保護），因此整個系統只需要一個電源。
- 即插即用兼容性，易於使用
- 您的Raspberry Pi的硬件和軟件音量控制
- 用於配置靜音和增益設置的板載硬件跳線（可以選擇使用開關更改跳線）
- 使用GPIO22靜音/使能（可以使用跳線J4覆蓋）
- 無需焊接
- 可選的紅外接收器包含在包裝中
- 未使用的GPIO引腳仍然可通過未擴展的擴展頭訪問
- 在Raspbian / NOOBS中完全支持駕駛員
- 兼容OSMC / Max2Play / RuneAudio / Volumio / Moode / PiCorePlayer / PiMusicBox / OpenELEC等
