Description

The JustBoom Amp HAT is a high quality audio amplifier designed specifically for the Raspberry Pi. As well as an audio amplifier, digital to analog conversion is also included 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.

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 of setting up this Raspberry Pi HAT. 

Includes a Class-D power amplifier chip with built in 192kHz/32bit 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 to 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. All of the unused Raspberry Pi GPIO pins are still accessible on the Amp HAT for easy customisation of your project – add additional sensors, buttons, LEDs, rotary encoders or anything your heart desires.

Pairing the Raspberry Pi with a high quality audio power amplifier provides the perfect solution for a number of exciting projects and applications where the standard on-board audio on the Raspberry Pi simply won’t cut it. Here are some possible use cases for the JustBoom Raspberry Pi Amp HAT and your Raspberry Pi computer:

•Multi-room streaming/local audio player

•Interactive art projects with audio requirement

•Arcade table projects with high quality, immersive audio

•Streaming (either from cloud or network storage) high-definition audio player

•Internet radio player with high quality stereo audio

•Refit old radios and boomboxes (Roberts radios etc) with high quality streaming audio

•And many many more….

Features.jpg

•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 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

•Compatible with Raspberry Pi  A+,B+, 2B and the new 3B

•Mounting hardware included

•Optional IR receiver for the JustBoom Raspberry Pi Amp is included in package

•Unused GPIO pins still accessible via unpopulated extension header

•Compatible with OSMC / RuneAudio / Volumio / Moode / PiCorePlayer / PiMusicBox / OpenELEC and others

•Fully compatible with the recommended JustBoom Player software.

Getting started guide for the software.


Technical Information.jpg

•Texas Instruments TAS5756M Amp / DAC chip – 192kHz / 32 bit.

•Maximum power output of 2 x 55 W ( 2 x 30 W RMS).

•This board powers both the amplifier and Raspberry Pi from a single 2.1mm DC jack power supply. For 8 Ohm speakers, we recommend a 24 volt power supply with at least 75 Watt output power (POWERPAX SW4527 or similar plus C5 cable). For 4 Ohm speakers we recommend a 15 to 19 volt power supply with at least 58 Watt output power (POWERPAX SW4520 or similar). These power supply guidelines will ensure maximum output performance of the amplifier. However there are other options which can be found in our power supply recommendation document. (Please note: it is highly recommended to use an external power supply. If you power the Amp HAT over the GPIO pins and do not use one of the recommended power supplies, the maximum output power will be 2 x 3 Watts)

•Advanced ESD protection

•Dual inductors on board for footprint efficiency

•Fully integrated hardware volume mixing via “alsamixer” or any ALSA compatible application

•Integrated EEPROM for automatic Raspberry Pi devicetree driver configuration

•The JustBoom Raspberry Pi Amp is fully HAT compatible

•Optional Vishay TSOP4838 IR receiver included in package (solder yourself if required)

•Total harmonic distortion (THD+N) of 0.006 % at 1 W, 1 kHz. Signal to noise ratio (SNR) of 104 dB A-Wtd (Ref. to THD+N = 1%)

•Ultra low noise voltage regulator for the best audio output (LDO 10uVrms)

•Fully digital sound path for optimal audio performance

•Mute/enable via GPIO22 and also there is jumper J4 for enable, that overrides software enable


We also have DAC and  Digi Raspberry Pi HATs available to purchase.

JustBoom Amp HAT for the Raspberry Pi 1

描述

JustBoom Amp HAT是專為Raspberry Pi設計的高品質音頻放大器。除了音頻放大器,還包括數模轉換,所以不需要外部聲卡或DAC。只需將即插即用(HAT)添加到您的Raspberry Pi A +,B +,2B或新3B上即可立即使用。

只需將Amp HAT連接到一組無源揚聲器,您可以快速啟動並運行,在設置此Raspberry Pi HAT的幾分鐘內即可享受無瑕疵的高品質音頻播放。

包括內置192kHz / 32位DAC的D類功率放大器芯片,峰值功率輸出為2 x 55瓦特。 JustBoom Amp HAT通過兩個揚聲器電纜連接器塊輸出音頻,可以接受任何高達14 AWG的電纜,並為4或8歐姆無源揚聲器提供清晰的音頻。 Amp HAT使用I2S接口進行音頻輸入,與USB解決方案相比,可以降低Raspberry Pi上的CPU負載。它還旨在通過40引腳GPIO接頭對Raspberry Pi進行後備電源,這意味著整個系統只需要一個電源。所有未使用的Raspberry Pi GPIO引腳仍然可以在Amp HAT上訪問,方便您自定義項目 - 添加額外的傳感器,按鈕,LED,旋轉編碼器或任何您所需要的內容。
