Product Details
Abundant headphone jacks, convenient to connect to different headphone single-ended 6.35, balanced 4.4, balanced 3.5pro, balanced XLR.
The matrix relay volume is used to ensure the same volume on the left and right, so there is no need to worry about noise bias over time.
Use FPGA to program human-computer interaction system, remote control volume, can be used at current level.
Use OPA1642 and OPA1678 to match impedance to facilitate different front-end compatibility, not picking signals Three-stage gain adjustment to adapt to headphones with different impedances. The pre-amplification and drive circuit adopts the combination of LME49722+LME49724.
Single-ended and balanced are designed separately, completely independent circuit. Single-ended and balanced at the same time have high-power output, enough to drive most common headphones. Built-in linear power supply, high-quality audio dedicated toroidal transformer
