7.10.2. CROSSOVER
Crossover parameters group contains FILTER TYPE, EDGE LINK and FREQUENCY parameters
for each of the two crossover filters (low-pass and high-pass). These filters split the frequency spectrum
in different bands matching each speaker.
 FILTER TYPE selects the crossover filter type. Following filter types are available:
Butterworth 6, 12, 18 or 24dB/oct
Bessel 12, 18 or 24dB/oct
Linkwitz-Riley 12 or 24dB/oct
 EDGE LINK links cut-off frequencies of a filter and of its opposite (high-pass  low-pass,
low-pass  high-pass) in other channels, to edit only one parameter but simultaneously control
two. For example, if you activate EDGE LINK between OUT1 crossover low-pass and OUT2,
editing OUT1 low-pass filter frequency value will simultaneously change OUT2 high-pass filter
frequency value.
 FREQUENCY is made of a potentiometer and a linked numerical value to set the filter cut-off
frequency within 20Hz – 20 kHz range.
7.10.3. FAN
The fan graphics will remain stopped while there is no connection to the
DPM3003 hardware. As soon as the CONNECT key is pressed (main panel, left
corner) and the link with the hardware is established, the fan will start moving.
7.10.4. DELAY
DELAY section sets an independent delay time for each channel. This delay
time will be applied to the audio signal in order to precisely align speakers.
Delay time can be set with different units depending on UNITS parameter.
Available units are Milliseconds, Seconds, centimetres and meters. DELAY can be
set in 20.83 micro-seconds steps (minimum).
The delay memory is a common resource for all processing channels. You have a 910 ms total
delay time to share between all channels. So it's possible for a value to be unavailable (the value doesn't
change anymore even if you keep on rotating a potentiometer) when you try to increase a channel delay
time if the available 910 ms of delay memory are already consumed by other channels.
In order to avoid weird noises and clicks in the output signal, edition made with DELAY
potentiometer is only validated when the mouse button is released. Audio is then temporarily muted (for
a variable time, depending on delay time), for the memory to be set.
