Setup Requirements
A pink noise generator as a source. An audio meter capable of measuring in db. An XPanel/touch panel with Audio Setup loaded.

Setup Procedure
Connect the pink noise generator to a source input. Assure the pink noise generator’s output is relative to the other sources. Set the whole house to the input that the pink noise generator is connected to and set the same volume for all rooms at any level. Measure the sound level with a db meter in every room to find the quietest room. Turn off all rooms.

Using Audio Setup, press the “Begin Setup” button, select the quietest room, select the source the pink noise generator is connected to, and ramp the room volume to 90%. Measure the sound level (measure from where the room will most likely be populated) with a db meter and write down the reading. This reading is the calibration standard for the remaining rooms.

Go to another room. Using Audio Setup, set the max volume to 50% and the room volume to 90%. Using a db meter to measure the sound level, ramp up the max volume until you reach the calibration standard recorded in the first room.

Repeat the process room by room until all rooms have been calibrated. Once all rooms have been calibrated, press the “Save/Exit” button in Audio Setup. Turn on all rooms to the input the pink noise generator is connected to. Walk around and verify the sound level is the same in each room. If the sound levels are consistent, switch to a music source and walk around to confirm again.
