Bewertungen

The TPA3116/18 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)
- PCB with extra copper (since on transient’s current can spike to 5A)

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.

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+)
