a. In most of the cassette machines two identical audio channels are
provided, one for each of the tracks on the tape.
Each has an independent line
output socket. The output of the channel is present whenever power is turned on.
Many models have an audio monitor jack, the output of which is selected by a switch
on the front panel and can be either Channel 1, Channel 2, or a mixture of both
(fig 3-13).
b. The video out of the cassette machine is connected to the video in of the
monitor (fig 3-13). If there are two video inputs to the monitor, the either can
be used. The TV monitor will have an audio input. This is connected by a separate
cable to the line out of the machine. Use the output of the channel with the audio
recorded on it. If no sound is heard, then try the other line out socket (fig 3-
14).

c. Recording on a video cassette requires video and audio inputs.
When
recording, the connections to the machines must be made in addition to those
required in playback.
A difficult aspect of recording is in making the proper
connection (fig 3-15).
