Battery compartment cap ｀ Emerson Electronics I www.emersonaudio.com How to Connect To start using your wireless microphones, the receiv­ er must be connected to the audio input of an ampli­ fier, karaoke, or PA system. Your receiver can be connected to systems with: 1/4 » input • 1/8" input (with an optional adapter〉 To connect the receiver and microphones: Use the patch cable to connect the 1/4 » AUDIO OUTPUT jack of the receiver to the 1/4" connector of the input system (e.g., an amplifier, karaoke, or PA system). 2.Connect the receiver to power (AC 110 V). Fully extend the antennas and position them for op­ timal reception. The wireless microphones require one "9V" battery each. To access the battery compartment, twist and unscrew the bottom cap of the microphone. Load one "9V" alkaline battery into the compartment , and then screw the bottom cap back into place. @ Make sure to match the ” + “ and ” -” polarities marked inside the battery compartment. 4.Turn the receiver on, and then turn the micro­ phones on. When the microphones are connected to the receiver, the A and B indicators will light green and red, respectively. (D Th _ e gre _ en A LED corr : esponds to the microphone marked with a green band; the red B LED corresponds to the mi­ crophone marked with a red band. Lower the input level on the input sys­ tem before turning on the microphones. Slowly readjust the input to a comfort­ able level after the microphones are turned on and connected. 1. 3 Placing Your Microphone The optimal position for your microphone relative to the sound source depends on a few factors, but it is mostly a matter of trial and error. Experiment with different distances and positions to see which sounds best, but keep the following things in mind. Cardioid Cardioid microphones are more sensitive to sounds that are in front of it. Sounds from behind the micro­ phone will be slightly muted Cardioid microphones are great for vocal or speech recording. Page2 When using a microphone for vocal or speech work, the closer you are to the microphone the more likely it will pick up "plosives" when record­ ing. Consider placing a pop filter between the speaker and the microphone.
