The DCM Manager software allows balancing of the high/low or high/mid/low signals being fed to the
front panel monitor speaker. Input pink noise into all of the DCM input channels and select individual
channels using the DCM front panel buttons.
Select the surround channels first to make a reference level (the DCM contains no processing of these
channels). Now select other channels one at a time and balance these gain settings for a sound level
similar to the surround channels.
The manufacturer of any loudspeaker will be able to supply you with recommended crossover settings. The
DCM offers additional filters (high pass, parametric EQ, screen EQ, and Horn EQ), driver and channel delay,
polarity, and gain adjustments which can be used as additional compensation for speaker and installation
characteristics.
Driver delay settings compensate for the physical displacement between transducer centers within one
speaker. Consult the speaker manufacturer for help in determining this setting. Channel delay compen-
sates for the distance that a speaker is located from the screen. We have included some screen delay
adjustment, but most typical theaters will not need to use this because surround channels are delayed
coming from the cinema processor. Consult an acoustic consultant for the proper calibration method, or
experiment until the sound from the screen together with sound from the surround speakers sounds more
“clear”.
WARNING: Inappropriate crossover settings can damage speakers!
