Volt+ Class D Amplifier
Product Overview
The Volt+ is a high-performance standalone Class D amplifier, engineered for audiophiles who demand clean, powerful, and precise sound. Built around the TPA3118 amplifier IC, this board improves on the stock design with superior grounding, anti-pop circuits, and premium brand-name components.
Unlike the Volt, Volt+ features RCA stereo inputs and a Capacitance Multiplier circuit, which suppresses power supply spikes and noise by up to 60dB—ensuring optimal performance for your DACs and audio systems. Volt+ can be used as a standalone amplifier or paired with Rabas DACs such as Piano and Piano 2.1 for a fully integrated audio setup.
Features
- High-fidelity Class D amplification delivering up to 2 x 50W max output
- Optimized TPA3118 IC with improved grounding for ultra-clean audio
- Anti-Pop circuit to eliminate turn-on and turn-off noise
- Bootstrap snubber modification for smoother transient response
- Premium brand-name components: Würth inductors, TI chipset, film capacitors, ±1% thin-film resistors
- Radio interference avoidance switch for low-noise operation
- Enhanced PCB design with extra copper to handle transient currents up to 5A
- 4 output filters, 4 EMI snubbers, 4 bootstrap capacitors, and gain-setting components
- Provision for stepped attenuator volume control
- Two board options: Volt (DAC plug-in shield) or Volt+ (standalone with RCA IN)
- Capacitance Multiplier circuit in Volt+ reduces power supply spikes and noise by ~60dB
