KV2 Audio SDD3 - Manual (Page 11)

Using the System
Page | 11
Delay for main mono PA, delay for additional PA / mono fill-in delay, with stereo cardioid
One SDD3 controls one channel of the system, the second channel controls the second SDD3 unit.
The main PA works through SDD3 channel A to delay the PA for optimal time alingment with the stage
position. The secondary, or side-fill PA works through the full range channel B of SDD3 for proper time
alingment with the main PA. Subwoofers work in stereo, cardioid or normal mode.
When using this system, it is possible to move separately in time, (change distance) of the main PA,
sidefills and subwoofers compared to the stage position.
