Now offered in two versions!  Base version is just the Volt+ Amp.  Deluxe version includes Volt+ Amp, Stepped Attenuator, and acrylic case.  

The TPA3118 class D amplifier IC is a leap in terms of audio quality.

Our board is a high quality implementation of the stock design.

- Using TPA3118 (better grounding of main IC)
- Anti-Pop circuit
- Bootstrap snubber mod
- Brand name components as per picture
- Radio avoidance switch (to reduce interference)

Note that PCB comes in 2 flavors:

1. Volt is a shield and beneath it has connector that will plug into our DACs (Piano 1.1 and Piano 2.1). It has no RCA inputs. (Capacitance Multiplier can be added as a standalone board).

2. Volt+ is a standalone amplifier with RCA IN (stereo). In addition to everything that the Volt has, we have added a circuit in the power supply that will reject spikes and noise to about 60db. The name of the circuit is "Capacitance Multiplier". Please note that Class D amplifier needs a quiet PSU.

Volt+ can be used with our DACs through the RCA input, as a standalone board.

Unlike our competitors that blindly copy the THD+N and SNR from datasheet, the files here show the real and tested characteristics of our Volt+ at different W of output power.

Note that in most cases we beat the THD+N and SNR from TI designed, evaluation board.

Features
  • This class D amplifier goes up to 2 x 50W Max
  • The components used are specifically designed for high end audio devices (Würth Inductor, TI chipset, film capacitors and ± 1% thin film resistors)
  • VOLT AMP boasts 4 output filters, 4 EMI Snubbers, 4 bootstrap capacitors and gain setting components
  • We are using CM filter circuits in power section to reduce maximum ripples in power
  • We are using 10K logarithmic Potentiometer for Volume control. Available with different Input connectors: 2 x RCA
  • Comes in two flavors (Volt and Volt+)
  • Power Supply Required: 16-24V (we recommend 19V), 60-90W
  • Power Connector Jack Barrel size: 3.00mm ID (0.118"), 6.50mm OD (0.256")
