ASG Tech Note: Connecting and Communicating with DSA
Page 9 of 10
Left clicking once on the cluster name will light up the LED’s for entire cluster (all
modules). Left clicking on the individual DSA modules within that cluster will light up the
individual LED’s on those DSA modules. This is helpful in making sure the correct DSA
modules are assigned properly, and that the orientation of the DSA modules is correct.
6. EQ and Steer the DSA Cluster(s).
Once connected, you can EQ and Steer your DSA cluster. It is important to realize that individual
DSA modules are never steered or EQ’d – only clusters are steered and EQ’d. You can get to the
steering and EQ windows either through the “Tools” drop down menu, or by right-clicking once on
the cluster you wish to steer or EQ.
In the EQ section, you should start off with your input gain at –10dB (default for firmware version
58 and higher). This may be increased or decreased as needed depending on the system’s gain-
staging.
In the steering section, you want to switch from ‘Specify Coverage Pattern’ (which is default) to
‘Match Coverage to Listening Area’.
DSA is a loudspeaker system – processing, amplifiers, and loudspeakers. In a DSA250, there are
sixteen drivers, sixteen channels of DSP, sixteen channels of amplification. There is the
possibility of some amp noise commonly referred to as “hiss” if the DSA loudspeaker is not
properly gain staged with the rest of the system, especially if the signal feeding DSA is low, and
the input gain on DSA is being used to compensate.
