1.16 dV-DOSC PRESETS
dV-DOSC presets are provided in LO and HI versions with differing amounts of HF shelving
equalization. In general, LO presets are flat (smooth) while HI presets have an additional 3 dB of
shelving eq (bright).
Stereo 2-way dV-DOSC presets offer the choice between two high pass filters for the low section and
two shelving eqs for the high section. For dV-DOSC 2W 100 presets, a 100 Hz, 24 dB/octave slope
HPF is applied to the low section and the limiter threshold is set at +7 dBu. For dV-DOSC 2W 80
presets, an 80 Hz 24 dB/octave slope HPF is applied to the low section and the limiter threshold is set
at +5 dBu. The dV-DOSC 2W 80 Hz preset also includes optimized LF shelving equalization for
standalone applications or for AUX SUB drive using SB218 DELAY ARC 80 Hz or SB218 LCR 80 Hz
presets. For either of these presets, LO (smooth) or HI (bright) versions are provided with differing
amounts of shelving eq for the high frequency section.
Stereo 3-way presets are provided for dV-DOSC plus dV-SUB with a variety of crossover points
available between dV-SUB and the dV-DOSC low section (80, 120 and 200 Hz). The 80 Hz crossover
point is intended for applications where dV-SUB and dV-DOSC are physically separated (eg. ground
stacked subwoofers with flown dV-DOSC). The 120 Hz crossover point is considered optimal in
terms of power bandwidth for both dV-SUB and the dV-DOSC low section and is for closely coupled
flown or stacked configurations. The 200 Hz crossover point allows the dV-SUB to function as a
combination sub/low enclosure and also provides an operating bandwidth that corresponds to that of
the V-DOSC low section. The 200 Hz crossover point is for closely coupled configurations except for
coplanar flown configurations, i.e., when dV-SUB arrays are flown on both sides of a dV-DOSC array.
Note: For a ratio of 3:1 dV-DOSC:dV-SUB low frequency extension is provided that results in the same low
frequency tonal balance as V-DOSC (without subwoofers)
