MONITOR Operation
The ATS-1 Access has a built-in monitor for audible monitoring of
signals, either with stereo headphones or through a built-in speaker
that receives the combined A and B channels.
To use stereo headphones, plug them into the MONITOR jack. To use
monophonic headphones, a special stereo-to-mono headphone
adapter must be used. When headphones are connected, the internal
speaker is disabled.
The MONITOR Knob controls the amplitude of the headphones or the
internal monitor speaker.
Normally the speaker or headphones will monitor the input signal, so
the signal heard will be the same as the signal at the input. There is a
resistor connection inside the instrument to change the source so that
the monitor follows the measured signal, after being processed for the
reading. To make this change, see Appendix C.
