Technical Specifications:• Frequency Response (-3dB): 2Hz ~ 76kHz.Frequency response helps determine whether the sounds the system needs to reproduce fall within the product's or audio source's operating range.• Total Harmonic Distortion (THD): A reference metric for device performance when comparing input and output signals.• Signal-to-Noise Ratio (SNR): 112dB.The difference between the perceived audio signal and the noise floor.• Channel 1 Input Sensitivity:Microphone (XLR): Min. 500mV ~ Max. 7mV.Line Input (1/4" jack): Min. 620mV ~ Max. 7.6mV.These values indicate the acceptable voltage range for the device, preventing signal saturation caused by excessive voltage or a lack of response due to insufficient signal strength. • Channels 2 and 3 Input Sensitivity: Line Input (1/4" jack/RCA) Min: 2.55V ~ Max: 60mV.This value indicates the minimum and maximum voltage range the device can accept to avoid saturation caused by excessive voltage or a lack of response due to insufficient signal strength.
