ImpedanceA minimum load impedance of 800 ohms should be used for maximum signal handling and minimum distortion. The impedance may be as low as 150 ohms, but a reduction in output level and output clipping level will result.SPECIFICATIONS*100 Hz to 20 kHz;THD < 1%.
**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
