The Yamaha DM2000, DM1000, and 02R96 internally provide two types of pink noise for use as
monitor adjustment signals; -20 dBrms “broad-band pink noise” and 500 Hz - 2 kHz “narrow-band
pink noise.” The band level of the 500 Hz - 2 kHz pink noise is approximately 5 dB greater than the
band level of the broad-band pink noise. Thus, you can use the DM2000, DM1000, and 02R96 to
make adjustments referenced to 85 dBC to both “broad-band pink noise” and “500 Hz - 2 kHz pink
noise.”

The DM2000, DM1000, and 02R96 allow you to adjust the playback level of each speaker in a range
from –12dB to +12dB with a precision of 0.1 dB steps. Also, the “SET SPL 85 dB” function lets you
specify a desired position of the master volume as the 85 dB indication, and the “SANP TO SPL85dB”
function lets you instantly switch the volume from any master volume position to the reference
playback level of 85 dBC.
