Operation Manual

22
The Low band has a low-pass crossover filter, and the High band has a high-pass and a low-pass crossover filter.
A 2nd order low-shelf filter with frequency variable over the range 10Hz to 25kHz, and boost/cut from –15 to +15dB.
A 2nd order high-shelf filter with frequency variable over the range 10Hz to 25kHz, and boost/cut from –15 to +15dB.
Six bands of bell (parametric) equaliser, each band having frequency variable over the range 10Hz to 25kHz,
bandwidth variable from 0.1 to 5 octaves, and boost/cut from –15 to +15dB.
Delay adjustable up to 405ms on input A and B.
Delay adjustable up to 80ms on each output.
Adjustable gain from –40 to +15dB, and mute.
EQUALISATION FILTERS
The six Bell filters (Parametric equalisation filters) may each be used to emphasise (by applying a positive Level parameter
setting) or de-emphasising (by applying a negative Level parameter setting) a range of frequencies centred on the setting of
the Frequency parameter, and encompassing a frequency range determined by the Bandwidth parameter setting.
The two shelving filters allow all frequencies below that of the frequency parameter (for the Low shelf) or all frequencies
above that of the frequency parameter (for the high shelf) to be emphasised (by applying a positive Level parameter setting)
or de-emphasised (by applying a negative Level parameter setting).
CROSSOVER SHAPES
In addition to the usual Butterworth, Linkwitz-Riley and Bessel filter shapes, VNET™ processing provides access to
Hardman crossover filtering. Hardman filters produce much steeper cut-off slopes for a given order than conventional
crossover alignments, without any additional group delay. This allows a lower order filter to be used without sacrificing cut-off
characteristics, but with smoother group delay and less severe phase penalties, giving a more natural sound. Hardman filters
and also provide identical phase characteristics between adjacent bands (like Linkwitz-Riley), so the polar performance is
rock steady.
We also employ phase matching on our Bessel filters, so adjacent bands are in-phase throughout the crossover region.
LIMITING PARAMETERS
Note that the limiters do not require you to set the ratio, attack time or release time since they are automatically derived from
the crossover frequency chosen.
SMOOTH ADJUSTMENT
Whenever a parameter is changed, VNET™ will assess the likely impact on the signal path, and will intelligently smoothly
ramp to the new value, or mute for a short time if the change could otherwise cause any undesirable sound to be reproduced.
SAVING & RECALLING DATA
Device Data may be saved to disk or opened from disk.
PodWare Device Data files (with file extension .dse) contain all the data necessary to restore a device to exactly the same
state as when the file was saved.
If the current settings have been changed since the last file save or file open, the Save Icon on the toolbar will be shown in
solid colour. If the settings are already safe, the Save icon appears grey.
If a file is opened when on-line to devices, the new data will be sent to the device, overwriting whatever was in the device. A
warning will be given before this is done.
Data saved from one device can be reopened in another to save time inputting data. (Assuming settings are to be duplicated)
Podware will always try to protect your data, warning you if you are attempting an action that could cause loss of data.
