JustBoom AMP TPA3118D2DAPStereo Amplifier 2x30W 8Ohm

The 2x30W JustBoom Amp is a high-quality standalone audio power amplifier designed to be either stacked with a JustBoom DAC or JusBoom DAC HAT or amplify an external source through the stereo RCA analog input. Equipped with one of these two DACs it transforms a Raspberry Pi 2 or Pi3 in high quality audiophile desktop amplified solution.

TheJustBoom Amp is designed to be simple to use without soldering necessary with all the mounting accessories already provided. This is a real plug and play device. In addition it has balanced stereo line inputs on screw terminal.

Highlight of the JustBoom Amp:

• Input gain selectable by jumper (20 dB, 26dB, 32dB, 36dB)
• Amplifier voltage level gain selectable by jumper (14V and 21V)
• Can be powered by a Raspberry Pi 2 or Pi3 (GPIO) or by an external power supply (24 volt max 3.5A)
• Double shielded output inductor low magnetic radiation
• Texas Instruments TPA3118D2DAP Class-D Amplifier
