Stereo / Mono Formats
There is only one 'standard' layout of the
processing blocks, but flexible routing and control
linking allows this layout to be adapted to a wide
variety of applications.
There are two 'Formats', Mono or Stereo. With
the Mono format, all outputs have unique para-
meter settings, and all outputs are identical in
terms of processing functions and routing
capability. This is the most flexible Format.
Stereo format pairs the inputs and outputs for
stereo operation, the parameters of each member
of the pair being identical. The routing of inputs
to outputs is fixed. This format is intended for
symmetrical stereo operation, eliminating the
need to make identical parameter adjustments for
each channel.
The channel pairing is:
• Left and Right Inputs
• 1 & 4: Outputs 1 (routed from A input)
and 4 (routed from B input)
• 2 & 5: Outputs 2 (routed from A input)
and 5 (routed from B input)
• 3 & 6: Outputs 3 (routed from A input)
and 6 (routed from B input)
6 Input Channels
Gain
Knob A: Gain, adjustable in 0.2dB steps from
–80 dB to +20 dB
Delay
Knob A: Delay, adjustable in variable steps from 0
to 400 ms
The delay parameter is adjustable in fine steps at
low values; the adjustment becomes progressively
coarser as the value increases. The velocity
sensitive Parameter Knobs therefore provide
accurate setting of driver offset delays (typically
below 10ms) and rapid setting of longer system
alignment delays.
High Pass Filter
Knob A: Frequency, out (off), 10.0 Hz to 25.6 kHz
in variable steps
Knob B: high pass filter type
System high pass filtering is provided for the
input signal. This is the preferred location for
high pass filtering as it affects alloutputs and can
therefore improve inter-band phase relationships.
Filter type is selectable from Butterworth, Bessel,
Linkwitz-Riley and Hardman. Filter slopes of up to
4th order or 24dB / octave are provided. Not all
filter types are available in all slopes. For example
18dB / octave Linkwitz-Riley filters do not exist.
The Hardman type filter is always described by its'
order as the filter becomes progressively steeper
rather than following a linear slope so a dB/
octave description is not accurate.
Parametric Equalisation
Eight sections of equalisation are provided, two
shelving filters and six fully variable parametric
sections.
High and Low shelving filters
Knob A: Frequency, 10.0 Hz to 25.6 kHz in
variable steps
Knob B: Slope, 6 to 12 dB / octave in 1 dB steps
Knob C: Gain, +/-15dB in 0.2 dB steps
The frequency is specified as point where the filter
deviates by 3 dB from the gain value.
Parametric filters
Knob A, Centre Frequency, 10.0 Hz to 25.6 kHz in
variable steps
Knob B, Width, display selectable, Q or BW
(Bandwidth)
BW adjustable from 0.05 to 5 octaves in variable
steps
Q adjustable from 14.2 to 0.2 in variable steps
Knob C, Gain, +/-15 dB in 0.2dB steps
7 Output Channels
Gain and Polarity
Knob A: Gain, adjustable in 0.2dB steps from
–80 dB to +20 dB
Knob B: Polarity, selectable, normal or reversed
with reference to other outputs
Delay
Knob A: Adjustable in variable steps from 0 to
80 ms
As for input delay, velocity sensitive Parameter
Knobs provide finer adjustment at low levels and
rapid selection of higher values.
High and Low Pass Filters
Knob A: Frequency, <<out, 10.0 Hz to 25.6 kHz,
out>>
Knob B: high pass filter type
Filter type is selectable from Butterworth, Bessel,
Linkwitz-Riley and Hardman. Filter slopes of up to
8th order or 48dB / octave are provided. Not all
filter types are available in all slopes. For example
18dB / octave Linkwitz-Riley filters do not exist.
The Hardman type filter is always described by its'
order as the filter becomes progressively steeper
rather than following a linear slope so a dB/
octave description is not accurate.
