Introduction - QSC DCM series User Manual

II. INTRODUCTION
The QSC Audio DC series (together with QSC DCA amplifiers) is designed to perform all of the electronic
functions required for the audio portion of a cinema playback system except for the cinema processor unit
(for example, Dolby, Sony, or dts) and the speakers.
The DCM series consists of one of three hardware units (DCM-1, DCM-2, and DCM-3) and the PC based
control software called the DCM Commander. The DCM-1 supports a typical Dolby 6 ch. 2-way system. The
DCM-2 supports a typical Dolby 6 ch. 2-way or 3-way system, and the DCM-3 supports a Sony 8 ch 2-way or
3-way system. These systems include many outputs which are paralled to allow for maximum theater con-
nection flexibility.
Notice that the DCM series takes advantage of the DCA amplifier DataPorts to allow extremely easy and
reliable connection to all of the amplifiers, with all inputs and monitoring signals being connected by one
low cost, mass termination cable. This cabling system allows a QSC cinema equipment rack to be wired up
much faster than traditional XLR or barrier strip termination products!
Another critical feature is the ability to download standard or custom configuration adjustments via the se-
rial port. For example, in a 15 theater megaplex with similar rooms and equipment, an installation techni-
cian can calibrate a DCM unit to the appropriate speakers and room configuration ONE TIME, and then
load these settings into the other 14 DCM units and be finished!
We are extremely proud of many of the "ground breaking" features contained within these products.
Thank you for your interest!
