Everything is just in the right condition.\u003cbr\u003eWith the help of a DAC, the function is expanded to a greater extent ：PA3s can be used with a DAC to expand the categories of digital inputs; if used with a DAC+HPA, more comprehen sive functions can be achieved.\u003cbr\u003eBalanced + Single- ended inputs ：PA3s provides TRS balanced input and RCA single: end- ed input. The u use of balanced input eliminates potential ground loop problems giving the pristinely clean audio without any hum.\u003cbr\u003eHigh output power ：PA3s could output 80W x2 at 4ohm load, 10% THD+N. In higher standard of THD+N of 1%，output power will be 65W x2 at 4ohm load. The output power is enough to drive any bookshelf speakers and even some floor speakers.\u003cbr\u003e2xMA12070 Fully balanced Class D amplifier ：Each channel of PA3s uses one MA12070 Class D power amplifier chip. This allows separation in layout improving performance and reducing crosstalk. The power is shared across two chips, the heat dissipation is also halved for each chip, improving reliability and extending the lifespan of the product.\u003cbr\u003e\u003cbr\u003e\u003cp\u003ePA3s Power Amplifier specifications ：\u003cbr\u003e SE IN：\u003cbr\u003e THD+N @1kHz (A-wt)：\u003cbr\u003e \u0026lt;0.0050% @4Ω 5W\u003cbr\u003e \u0026lt;0.0040% @8Ω 5W\u003cbr\u003e THD @20- 10kHz (20kBW)：\u003cbr\u003e \u0026lt;0.0080% @4Ω 5W\u003cbr\u003e \u0026lt;0.0070% @8Ω 5W\u003cbr\u003e SNR @MAX OuT 1kHz (A-W)：107dB\u003cbr\u003e Dynamic Range @1kHz (A-wt)：107dB\u003cbr\u003e Frequency Response：20Hz-40kHz ( ±0.1dB)\u003cbr\u003e Output Level：\u003cbr\u003e 46Vpp @4Ω\u003cbr\u003e 48Vpp @8Ω\u003cbr\u003e Noise (A-wt)： \u0026lt;70uVrms\u003cbr\u003e Channel Crosstalk @1kHz：\u003cbr\u003e Input sensitivity： -96dB\u003cbr\u003e Gain：25.2dB\u003cbr\u003e Channel Balance：0.5 dB\u003cbr\u003e Output Power：\u003cbr\u003e 80W x 2 @4Ω THD+N\u0026lt;10%\u003cbr\u003e 45W x 2 @8Ω THD+N\u0026lt;10%\u003cbr\u003e 65W x 2 @4Ω THD+N\u0026lt;1%\u003cbr\u003e 37W x 2 @8Ω THD+N\u0026lt;1%\u003cbr\u003e Adapter Impedance：4-8Ω\u003cbr\u003e \u003cbr\u003e BAL IN：\u003cbr\u003e THD+N @1kHz (A-wt)：\u003cbr\u003e \u0026lt;0.0045% @4Ω 5W\u003cbr\u003e \u0026lt;0.0040% @8Ω 5W\u003cbr\u003e THD @20- 10kHz (20kBW)：\u003cbr\u003e \u0026lt;0.0070% @4Ω 5W\u003cbr\u003e \u0026lt;0.0060% @8Ω 5W\u003cbr\u003e SNR @MAX OuT 1kHz (A-W)：112dB\u003cbr\u003e Dynamic Range @1kHz (A-wt)：112dB\u003cbr\u003e Frequency Response：20Hz-40kHz ( ±0.1dB)\u003cbr\u003e Output Level：\u003cbr\u003e 46Vpp @4Ω\u003cbr\u003e 48Vpp @8Ω\u003cbr\u003e Noise (A-wt)：\u0026lt;70uVrms\u003cbr\u003e Channel Crosstalk @1kHz：-100dB\u003cbr\u003e Input sensitivity：1.75Vrms\u003cbr\u003e Gain：19.5dB\u003cbr\u003e Channel Balance：0.5 dB\u003cbr\u003e Output Power：\u003cbr\u003e 80W x 2 @4Ω THD+N\u0026lt;10%\u003cbr\u003e 45W x 2 @8Ω THD+N\u0026lt;10%\u003cbr\u003e 65W x 2 @4Ω THD+N\u0026lt;1%\u003cbr\u003e 37W x 2 @8Ω THD+N\u0026lt;1%\u003cbr\u003e Adapter Impedance：4-8Ω\u003cbr\u003e \u003c\/p\u003e\u003cbr\u003eElectronics Home Audio Home Theater","brand":"My Store","offers":[{"title":"Default Title","offer_id":49032671789281,"sku":"P353529303159414346","price":37.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2048\/3553\/files\/6472d2fa3d2f8373070851a9b1f21c853242050278553f3180aceace7ed6fa43.jpg?v=1788528766","url":"https:\/\/doughnuthelmet.com\/products\/topping-pa3s-power-amplifier-ma120702-class-d-fully-balanced-single-ended-amp-80w2-rca-trs-power-amplifier-black","provider":"My Store","version":"1.0","type":"link"}
