The DVR can connect 4 channel’s audio input, but you can only select one for recording. To
display the DVR picture, the DVR video output signal should be transferred to your TV set or
monitor. Any TV set that has a “video input” terminal is suitable for displaying the image. The
figure above shows the video and audio signal line connection.
Notice: you can only connect one audio input at any one time, which means, if you
connect an audio input to CH1, you cannot connect any to CH2 through CH4.
