Content
Adjust the Volume control until the SPL meter reaches 83 dB with pink noise.
Ideally, 83 dB SPL should be reached when the Volume control is near the 12 o’clock mark.
You may mark position for 83 dB SPL. If it only reaches 83 dB SPL above two o’clock,
increase the power amps’ or active loudspeakers’ input sensitivity (higher dB value).
Conversely, you should decrease the power amps’ or active loudspeakers’ input sensi-
tivity (lower dB value) when it indicates 83 dB SPL before reaching the 12 o’clock mark.
If the input sensitivity is already reduced to the maximum but the output level is still too
high, the output level of the Crimson can be reduced by 10dB by using the DIP switch 6
on the bottom of the unit.
