With XMOS II chip XU208, Qualcomm Bluetooth chip QCC3031, the MX5 support USB, optical, coaxial, Bluetooth input. The MX5 can easily access a variety of audio sources, including electric amplifiers, set-top boxes, video recorders, cell phones, tablet PCs, etc.In addition to supporting a variety of digital inputs, the MX5 also supports fully balanced TRS and single-ended RCA analog inputs.\u003cbr\u003e【All interfaces support automatic power on\/off function】MX5 supports auto switch on\/off function in all interfaces (patented function), when a valid signal is detected, it will turn on immediately, and when the valid signal is lost, it will automatically shut down (enter standby) within a specific period of time. the MX5 provides three levels of sensitivity to choose.\u003cbr\u003e【High Power Digital Amplifier】Under a 4Ω load 10% distortion can output 70Wx2, 1% distortion can output 55Wx2; Under an 8-ohm load 10% distortion can output 42Wx2, 1% distortion can output 35Wx2 to meet daily use.\u003cbr\u003e【NFCA Headphone Amplifier】The MX5 has a built-in NFCA headphone module, low noise and distortion. It can be used with high-sensitivity IEMs or high-impedance large ears. The amplifier and earphone gain can be set. In order to adapt to the input signal of different strengths and weaknesses, MX5 provides 2 levels of gain for the built-in amplifier and earphone respectively. The gain can be set on the remote control.\u003cbr\u003e【Built-in EQ function, independent adjustment of treble and bass】MX5 supports both HF direct application and user-adjustable treble and bass application. The high and low tones are adjustable from -10dB to +10dB.【New feature】MX5 provides two setting memories, C1 and C2. Long press to memorize the current input selection, output selection, volume level, bass setting, treble setting, and gain setting.\u003cbr\u003e\u003cbr\u003e\u003cp\u003eTOPPING MX5 Power Amplifier DAC 384kHz DSD256 70Wx2 ClassD NFCA 1600mWx2 Headphone Amplifier \u003cbr\u003e\u003cbr\u003eMX5 headphone amp parameters： \u003cbr\u003eTotal harmonic distortion plus noise @ 1kHz (A - wt). \u003cbr\u003eUSB\/OPT\/COAX： \u003cbr\u003e \u0026lt;0.0030%@Output=750mW(32Ω) \u003cbr\u003e \u0026lt;0.0008%@Output=80mw(300Ω) \u003cbr\u003eSE： \u003cbr\u003e \u0026lt;0.0030%@Output=750mW(32Ω) \u003cbr\u003e \u0026lt;0.0020%@Output=80mw(300Ω) \u003cbr\u003e\u003cbr\u003eBAL： \u003cbr\u003e \u0026lt;0.0030%@Output=750mW(32Ω) \u003cbr\u003e \u0026lt;0.0020%@Output=80mw(300Ω) \u003cbr\u003e\u003cbr\u003eS\/N ratio@MAX OUT 1kHZ (A - wt) ： \u003cbr\u003eUSB\/OPT\/COAX: 120dB \u003cbr\u003eSE: 128dB \u003cbr\u003eBAL: 127dB \u003cbr\u003e\u003cbr\u003eDynamic Range@1kHz(A - wt)： \u003cbr\u003eUSB\/OPT\/COAX：120dB \u003cbr\u003eSE：129dB \u003cbr\u003eBAL: 127dB \u003cbr\u003e\u003cbr\u003eFrequency Response： \u003cbr\u003e20Hz-20kHz(+ 0.1dB\/- 0.3dB) \u003cbr\u003e20Hz-40kHz(+ 0.1dB\/- 1.0dB) \u003cbr\u003e\u003cbr\u003eOutput amplitude： \u003cbr\u003eUSB\/OPT\/COAX： \u003cbr\u003e5.6Vpp @G = L \u003cbr\u003e24.6Vpp @G = H \u003cbr\u003eSE： \u003cbr\u003e10.6Vpp @G = L \u003cbr\u003e24.6Vpp @G = H \u003cbr\u003eBAL： \u003cbr\u003e10.6Vpp @G = L \u003cbr\u003e24.6Vpp @G = H \u003cbr\u003e\u003cbr\u003eBottom noise @A-wt： \u003cbr\u003eUSB\/OPT\/COAX： \u003cbr\u003e\u0026lt;2.0uVrms @G=L \u003cbr\u003e\u0026lt;10.0uVrms @G=H \u003cbr\u003eSE： \u003cbr\u003e\u0026lt;2.0uVrms @G=L \u003cbr\u003e\u0026lt;10.0uVrms @G=H \u003cbr\u003eBAL：\u0026lt;2.0uVrms @G=L ; \u0026lt;10.0uVrms @G=H \u003cbr\u003e\u003cbr\u003eVocal channel crosstalk @1kHz： \u003cbr\u003eUSB\/OPT\/COAX: -93dB \u003cbr\u003eSE: - 93dB \u003cbr\u003eBAL: - 93dB \u003cbr\u003eInput sensitivity： \u003cbr\u003eUSB\/OPT\/COAX： \u003cbr\u003e0dBFS @G=L \u003cbr\u003e -1dBFS @G=H \u003cbr\u003eSE： \u003cbr\u003e3.9Vrms @G=L \u003cbr\u003e1.8Vrms @G=H \u003cbr\u003eBAL：7.8Vrms @G=L ; 3.6Vrms @G=H \u003cbr\u003e\u003cbr\u003eGain： \u003cbr\u003eUSB\/OPT\/COAX： \u003cbr\u003e6.0dB (Vrms\/FS) @G=L \u003cbr\u003e19dB (Vrms\/FS) @G=H \u003cbr\u003eSE：-0.2dB @G=L; 13.6dB @G=H \u003cbr\u003eBAL： \u003cbr\u003e -6.1dB @G=L \u003cbr\u003e7.6dB @G=H \u003cbr\u003e\u003cbr\u003eOutput impedance: \u0026lt;0.2Ω \u003cbr\u003eOutput power： \u003cbr\u003e1600mWx2@32Ω THD+N \u0026lt;0.1% \u003cbr\u003e1000mWx2@640Ω THD+N \u0026lt;0.1% \u003cbr\u003e260mWx2@300Ω THD+N \u0026lt;0.1% \u003cbr\u003eAdaptive impedance: \u0026gt; 8Ω \u003cbr\u003e\u003cbr\u003ePackage list: \u003cbr\u003eMX5 x1 \u003cbr\u003ePower adapter x1 \u003cbr\u003eRemote control x1 \u003cbr\u003ePower cord x1 \u003cbr\u003eUSB cable x1 \u003cbr\u003eBluetooth antenna x1 \u003cbr\u003e6.35mm to 3.5mm adapter x1 \u003cbr\u003eProduct manual x1 \u003cbr\u003eProduct warranty card x1 \u003c\/p\u003e\u003cbr\u003eElectronics Home Audio Home Theater","brand":"My Store","offers":[{"title":"Default Title","offer_id":52479895306460,"sku":"P353529386219213159","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0852\/4654\/2044\/files\/9db559d608ad0eb150b0638a1f8b17f7aa4429d0259f2e9da3c9940c2f5d031c.jpg?v=1788934781","url":"https:\/\/ybbyuihho.shop\/products\/topping-mx5-dac-class-d-amp-70wx2-nfca-headphone-amplifier-1600mwx2-usb-opt-coax-bt-trs-rca-in-desktop-home-audio-decoder-384khz-dsd256-with-remote-control-black","provider":"My Store","version":"1.0","type":"link"}
