{"type":"firestarter.listing","listing":{"id":"lst__10iPWdV","product_name":"TOPPING E70 VELVET AK4499EX Desktop DAC (Digital-to-Analog-Convertor)","category":"DAC (Digital-to-Analog Converter)","description":"\n\nThe all-new AKM flagship\n\nTake your listening to the next level with the E70 Velvet, a desktop DAC that features the flagship AKM AK4499EX DAC chip. Designed to pair perfectly with the TOPPING L70 Fully Balanced NFCA Headphone Amplifier, it decodes Bluetooth and USB audio at the highest levels available.\nAs if you were there\nThe newly designed AK4499EX flagship DAC chip uses a completely separate digital/analog solution to achieve sound “as if you were there.”\n24-bit Bluetooth\nEnjoy hi-def Bluetooth 5.1 and the latest wireless codecs: LDAC, AAC, SBC, aptX, aptX LL, aptX HD, and aptX Adaptive. The E70 bypasses the built-in DAC functionality of the Bluetooth chip and uses the AK449EX instead, ensuring the absolute best sound quality.\nLatest USB controller\nThe USB input of E70 VELVET has a wide range of compatibility: Windows 10, Windows 11, MAC, Linux, IS, Android can all be plugged and played.\n12V trigger interface\nThe E70 VELVET is equipped with a 12V Trigger interface, which has both active control (Trigger out) and passive control (Trigger in). With only one easy-to-obtain 3.5mm to 3.5mm cable, the E70 VELVET can be turned on and off synchronously with other devices equipped with a 12V Trigger interface.\nSelectable output port\nThe E70 features an output selection button with options for “XLR only,” “RCA only,” and “XLR + RCA.” This last option lets you run cables to two different destinations, such as a headphone amp and powered monitors, and listen to either without having to do the cable shuffle.\nPut it in preamp mode \nPut the E70 in preamplifier mode and control the output volume from -99dB to 0dB by the knob or remote control. This gives you a massive power advantage when using power amplifiers or monitor speakers. \nProduct highlights\n\nXMOS XU316\nBluetooth 5.1 LDAC transmission\nTHD+N: &lt;0.00006%\nAK449EX Velvet Sound
