Take the level meter with you to the listening position and point the measuring device directly towards the front centre speaker. Now start the sound generator of the receiver (or of the sound card or DVD player) and equalise all speakers in succession to the same level.
The position and alignment of the measuring device should not be changed during this procedure. For a devil sound level meter, proceed as detailed in the following:
1. Remove the protective tab from the battery.
2. Set the weighting to "A" - only the "A" position considers the full frequency range during measuring!
3. Set the response to Slow.
4. Set the Range to 70.
5. Start the test noise from your AV device.
6. Change the volume for every individual channel at the AV device so that the level meter shows 75 dB (meaning between +4 and +6).
7. Done!
