Audio Parameters
单端线路输出性能与参数(RCA输出,USB DAC/同轴解码/光纤解码,192K过采样)
*传统振膜通常依赖特定粘合剂将音圈粘合在振膜表面,这不仅增加振膜整体重量,还可能导致动圈运动时的动态失衡。局部重量分布不均会引起振动异常、改变振膜顺性,甚至因音圈擦圈而产生失真,最终影响单元整体表现。 About 0.017% (1kHz/0dB@10KΩ) SNR ≥116dB (A-weighted)
Crosstalk ≥110dB Noise floor <3.3uV(A计权)
Frequency response 20Hz~20kHz: attenuation<0.2dB Dynamic range ≥110dB
20Hz~65kHz: attenuation<2.9dB Line output level 2.2Vrms (1kHz@10kΩ)
