High and low level audio sources
d. Two video inputs are provided to the record electronics on the machines.
The simplest for the operator is that from the internal TV tuner. This requires no
connections other than the antenna at the rear of the machine, where a normal TV or
CATV antenna or lead is connected. The input select switch is set to the int or TV
position, and this switches the video and audio to the input of the machine. The
other video input is a video in socket which enables various external sources to be
connected. In this mode the select switch is set to the ext position, which routes
the video and audio inputs to the record amplifiers (fig 3-15).
e. A microphone can be plugged into the mic input (fig 3-15). Either channel
can be used in the normal record mode, but only Channel 1 if audio dubbing. Most
microphones will work but it is advisable to check with a test recording first.
Levels and the impedance may not be suitable.
