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:
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.
