While both wireless convenience and aesthetics. The new EW-MX440 Each group has 30 selectable frequencies safely victorious brand conference microphone, each machine is equipped with four 120 wireless conference microphone with adjustable frequency group, while increasing the channel ID code, fully resolved interfere with each other, on the same occasion can use a greater number. If you are using a wireless antenna YW-550 company with volume control attenuator, the volume control attenuator adjusted 0dB. In the group using 15 channels when the frequency table, odd or even choose to use an array of imported and domestic conference microphone, and then select up to 15 channels, as shown in the table, set the wireless microphone and radio tuner group number and channel number. The wireless microphone transmitter output converter switch to "L" side. The volume of the front panel to the right of the tuner control attenuator adjusted 0dB position. The volume on the right side of the front panel mix dispenser first connect the antenna control attenuator adjusted -20dB. If you are using a wireless antenna YW-550 company with volume control attenuator, the volume control attenuator adjusted 0dB.
