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)
- 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 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.
PA3118 D類放大器IC是音頻質量的飛躍。
我們的董事會是股票設計的高質量實施。
- 使用TPA3118(主IC更好的接地)
- 防流動電路
- 自舉緩沖模塊
- 根據圖片的品牌組件
- 無線電迴避開關(以減少干擾)
- 帶有額外銅纜的PCB(由於瞬態電流可以尖峰至5A)
請注意,PCB有兩種口味:
電壓是一個屏蔽,下面有連接器,可以插入我們的DAC(鋼琴和鋼琴2.1)。它沒有RCA輸入。(電容乘法器可以作為獨立板添加)。
2. 伏特+是具有RCA IN(立體聲)的獨立放大器。除了Volt的所有功能之外,我們還在電源中添加了一個將尖峰和噪聲抑制在60db左右的電路。電路名稱是“電容乘法器”。請注意,D類放大器需要一個安靜的PSU。
Volt +可以通過RCA輸入與我們的DAC一起用作獨立的電路板。
