Description
Product Overview
The Volt+ AMP is a high-performance Class D amplifier built around the TPA3118 IC, delivering exceptional audio quality for desktop and hi-fi setups. Unlike standard implementations, our board is carefully engineered with improved grounding, anti-pop circuits, and premium components to ensure clean, powerful, and accurate sound.
Volt+ functions as a standalone amplifier with RCA stereo inputs, or can be paired with Rabas DACs (like Piano 1.1 and Piano 2.1) for an integrated audio system. With advanced power supply filtering, including the Capacitance Multiplier, Volt+ minimizes noise and interference for a quiet, distortion-free listening experience.
Volt+ is tested under real-world conditions, delivering better THD+N and SNR performance than most standard evaluation boards, ensuring your music sounds crisp, dynamic, and detailed.
Features
- Powerful Output: Class D amplifier up to 2 x 50W max.
- Premium Components: Includes Würth inductors, TI chipset, film capacitors, and ±1% thin-film resistors.
- Advanced Circuitry:
- Anti-Pop circuit for smooth startup/shutdown
- Bootstrap snubber modification for clean signal
- EMI filters and snubbers for low interference
- Capacitance Multiplier in power supply to reject spikes/noise (~60dB reduction)
- Flexible Connectivity: RCA stereo inputs for standalone use; compatible with Volt shield DAC integration.
- Volume Control: 10K logarithmic potentiometer for precise adjustment.
- Two Variants:
- Volt: Shielded module to connect directly under Rabas DACs (no RCA inputs).
- Volt+: Standalone amplifier with RCA inputs and enhanced power filtering.
- Quiet Performance: Ideal for high-end audio setups; class D requires a low-noise PSU.
- Output Filters: 4 output filters, 4 EMI snubbers, and 4 bootstrap capacitors.
