4.Set the ACT THRES control to a point just before the ACT LED flashes amber. If audio activity is intermittent, see Operating In Systems With Intermittent Audio Activity.

5a. Using the chart and diagram on page 7, set the AMBNT THRES to the dBspl level where automatic increases to the system volume would be desired; or

5b. If the live ambient noise level while making these adjustments is at the desired trip point, then adjust the AMBNT THRES control to a point where the ACT LED flashes green.

6.Adjust the MAX GAIN to limit the maximum amount of gain the ANS1R can add to the system.

7.Adjust the RAMP SPEED control to the desired amount of signal gain per second (dB/s). Lower gain per second (dB/s) settings allows for gradual increases and decreas- es and ignores short bursts of noise. Higher gain per second (dB/s) settings allow the system to react quickly to shorter bursts of noise.

8.Test the system’s response to noise and, if necessary, set the ACT THRES control high- er if the maximum signal level is not achieved.Tweaking adjustments to Max Gain and Ramp Speed controls may also be necessary.

Operation In Systems With Intermittent Audio Activity

The ANS1R monitors the audio activity on the mix bus of the main unit. Using this infor- mation and the ambient noise level information, it regulates the amount of gain added to the system. This manner of operation allows the proper amount of gain to be added to keep the sources at the desired intelligible level without allowing it to become too great.

When working in systems that do not have continuous mix bus signals, like simple paging systems, the ANS1R will behave differently than mentioned above. In these types of sys- tems, when the ambient noise threshold has been exceeded, the ANS1R will ramp up to the max gain setting during the time when there is no signal on the mix bus.When audio activity appears on the bus, the ANS1R may begin to reduce system gain, at the RAMP SPEED rate, in an attempt to reach an optimum sound level.

With this type of intermittent audio operation, the setting of the MAX GAIN and RAMP SPEED controls will be the major factors in the operation of the system.The MAX GAIN should be set for a level that will allow the paging to sound intelligible over the worst case noise but not higher. The RAMP SPEED should be set to match the type of response to noise changes wanted. If it is for an area with loud machinery that turns on and off, then a fast ramp, 10-20dB/s, would be applicable. If it is an area where the noise gradually rises and lowers, then a slow ramp speed, 1-5 dB/s, would be used.The slower ramp speed keeps the system from boosting gain when short loud noises are encountered.
