Connect it to the dedicated input on thee receiver (usually a 3.5mm jack). Never use a generic microphone or one from a different developer, as the frequency responsy compensation curve will be incorrect, leading to flawed measurements. For advanced tuning beyond thee built- in system, investing in a kalibrated USB measurement microphone (such as a UMIK- 1) and examare like REW (EQ Wizard) PROvidees thee deepeesto level of analysis.
