Adding the Continuous sensing Ambient sensing leveler to your design and wiring it up

1. In the device tree, expand the DSP / Dynamics / Ambient Sensing Levelers folder.
2. Drag a Continuous Sensing or Continuous Sensing w/Router device over to the design page.

   

3. Wire the program source (typically background music and/or paging audio) directly to the Pr (program source) input wiring node.

   

   Any gain added or subtracted from this source starts from 0dB (unity gain), which is provided when the Ambient Sensing Leveler is bypassed.

4. Wire the output wiring node to the amplifier that drives the zone.

   

5. Wire the output wiring node to the speaker input (Sp) on the block.

   

   The Sp input is the return of the audio you would expect to hear from the speaker. In other words, the audio going into this node should be a duplicate of what the system is delivering to the amplifier that drives the zone.

   Tip: The speaker input is only used for measurement and will not pass audio through to the Ambient Sensing Leveler output node.

6. Wire the sense input (Sn) to a microphone which has been set up to sense ambience in the zone.

   

   In more complex projects, the microphone input may be processed by equalizers or filters before being fed into the Sn input.

   As an alternative to using the microphone input, you can use a White Noise Generator to test the system.

   

   Note: When properly calibrated, the Ambient Sensing Leveler device will effectively ignore most program material coming into the microphone. Anomalies may occur as a result of locating the sense mic too close to the speakers. The Ambient Sensing Leveler will work best if the microphone is not in the direct or indirect path of any speakers.
