The JustBoom Amp is a standalone high quality audio power amplifier that is designed to either stack on top of the JustBoom DAC / DAC HAT or alternatively take a line level input. We've designed the JustBoom Amp to be simple to use - with no soldering required and all the mounting hardware already provided, this is a true plug and play device.Connect your JustBoom Amp to a set of passive speakers and you can be up and running quickly, enjoying flawless high quality audio playback within minutes of unboxing. UsesA standalone audio power amplifier card provides the perfect solution for a number of exciting projects and applications where standard audio resolutions just won't cut it, or where you want to give an extra kick to your JustBoom DAC / DAC HAT boards. Here are some possible uses for the JustBoom Amp:Compact standalone amplifier to pair with your existing DAC

• Paired with the JustBoom DAC / DAC HAT to offer al l in one DAC and amplifier for a compact high-quality audio solution
• Streaming (either from cloud or network storage) high-definit ion audio player
• Multi-room audio player
• Media center / set-top box living room entertainment system
• And many many more..Full high quality audio - up to 192kHz/32 bit
• Mounting hardware included
• Plug and play
• No soldering required
• Compatible with Raspberry Pi A+,B+, 2B and the new 3B
• Compatible with the JustBoom DAC and DAC HAT or alternatively use as a standalone device
• Onboard, hardware jumpers for configuring output voltage and gain settings (jumpers could optionally be changed with switches)
• Texas Instruments TPA3118D2DAP Class-D amplifier chip with maximum power output of 2 x 55 W ( 2 x 30 W RMS)
• On the JustBoom Amp there are five line input connections.
• For balanced inputs: L+ is hot line L- cold line for left channel; R+ hot line, R- cold line for right channel; middle is ground (or cable shield) connection.
• For unbalanced L+ is left line, R+ right line, L-, R- and gnd are ground connections and all three inputs should be shorted to same input ground.
• Dual inductors on board for footprint eff iciency
• The JustBoom Amp is designed with a 2.1mm DC jack power input which can accept an 8 to 24 Volt 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.
• Advanced ESD protection
