Silver HiFi Headphone Amplifier Y4553
Silver HiFi Headphone Amplifier Y4553
Merus Class D amplifier ：With the help of Infineon Merus Class D amplifer, MX5 can output 70W x2 under 4 ohm load 10% distortion, 55W x2 under 4 ohm load 1% distortion. Under 8 ohm load, 10% distortion can output 42W x2, and 1% distortion can output 35W x2, which can meet daily use.
NFCA Headphone Amplifier ：The MX5 has the NFCA circuit optimized for this unit, giving the ultra low noise and distortion. It pairs with high sensitivity IEMs and power hungry high impedance headphones nicely. The built-in headphone amp allows you to enjoy music by yourself without disturbing others.
Built-in EQ function, now you can adjust treble and bass ：MX5 supports users to adjust the treble and bass. The treble and bass provide adjustable ranges from -10dB to +0dB respectively.
2 step gain settings for both power amplifier & headphone amplifier ：In order to adapt to input signals with different strengths, MX5 provides two step gain settings for both power amplifier and headphone amplifier. The gain can be set on the remote control.
