6.3 Set Mode Configurations
Details of each item of the Set mode menu are as follows.
(1)Attenuator function setting
Use this function when the receiving signal is interfered by
strong signals of nearby channels. When you activate this
function, the DJ-X7 attenuates the receiving sensitivity at about
20dB. Although the reception level of the target signal you wish
to listen to weakens, this means that unnecessary signals also
become difficult to be received. And as a consequence, it may
make the target signal distinctly audible.
