Input Channels
Gain
• Knob A: Gain, adjustable in 0.2dB steps from –80 dB to +20dB
Delay
• Knob A: Delay, adjustable in variable steps from 0 to 400ms
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 (typica lly below 10ms) and rapid setting of longer system
alignment delays.
High Pass Filter
• Knob A: Frequency, out (off), 10.0Hz to 25.6kHz 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 all outputs 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.
