of one amplifier. For our finished graphics plate we combined the objects as shown below in Figure 3.3:
The container object is used to visually tie the objects together in one neat package. It serves only an aesthetic
function. The bar meter object is assigned to monitor the output signal from Channel 1 of the amplifier. It shows how
loud the background music is in the waiting room. We used the full range (0 to –40 dB) but we turned the peak hold

feature off and the labels off to keep the bar meter simple. We also added a separate text object as a label to show
the normal level that is needed in the waiting room. The pot object is assigned to control the input attenuator for
Channel 1. We gave it an operating range of 0 to –10 dB. With only a 10 dB operating range, it will be impossible
for the operator to turn the level too low. We also turned the labels off for the pot object and we added our own High/
Low labels to show the operator which way to move the control. Finally, we added the text objects at the top to
clearly identify these controls as the “Waiting Room Background Music” controls.
The operating instructions for this example are simple: Adjust the level control up and down so that the signal level
goes up to the “Normal” mark on the bar meter.
