Black Desktop DAC Headphone Amplifier J691
Black Desktop DAC Headphone Amplifier J691
【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.
【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.
【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.
【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.
