Calibration of the Monitoring System
The input signal level of the Crimson and the input sensitivity of the power amps or
active speakers should be matched to ensure a proper overall gain. An inappropriate
level matching results, for example, in a high monitoring level with a fairly low volume
setting (at 9 o’clock). Likewise, settings above two o’clock should sound really loud,
otherwise it is indicative of a matching problem.
For calibration we recommend using a SPL Meter (where SPL stands for “Sound Pressure
Level”). Place the measuring microphone at the listening position and playback pink
noise from a generator calibrated to 0 dBu. Each measurement should be done with one
channel (and loudspeaker) at a time. 83 dB SPL at the listening position is a good and
very common reference value.
