1-6 Introduction
faders are touch sensitive. No complex menus or toggle switches are
needed to automate a parameter; in automation mode, the touch and re-
lease of a knob or switch will record and playback the required motion.
An unlimited number of Snapshots can be stored in the system and re-
called. The D950 takes an instant to fully reset all audio parameters when
a stored Snapshot is recalled.
The D950 Series User Interface/Control Surface comprise a variable num-
ber of input/output channel strips plus centralized monitoring and related
functions that can be arranged in any configuration to suit the user's needs.
Input frames accommodate from 4 to 64 channel strips, each of which can
address 10 individual Layers, arranged in five banks of two layers each.
An operator can instantly address two separate mono/stereo signal paths
via dedicated Layer #1 and #2 buttons on each channel strip, enabling a
console equipped with five, 12-module bays of channel strips, for example,
can be set to instantly address a total of 120 simultaneous signal sources,
with 60 on-surface controls available at any one time. Other banks can be
reached via a central Bank Select unit. For added flexibility, channel as-
signments can be swapped in their location anywhere on the surface.
Each modular Channel Strip offers dedicated controls for input selection
(one of three possible sources, including a test tone generator for system
calibration and alignment); Direct Out; access to four of the multiple
Mono/Stereo Aux Send busses; EQ In/Out; Filter in/out; Compressor-
Limiter in/out; Expander/Gate In/Out; Insert on/off; Pan (stereo or sur-
round) In/Out; and Assign Select, which enables the quartet of rotary shaft
encoders and programmable "soft" switches to be used to modify parame-
ter settings for the target channel.
Each EQ section offers four fully parametric bands that extend from 20 Hz
and 20 kHz, with a ±18 dB gain range. In addition to a psycho-acoustically
corrected frequency response for high frequencies – similar to well-known
analog EQ designs – the section's pair of mid-bands can be switched be-
tween constant-Q and constant-range modes. High and Low bands can also
be switched to Shelve mode.
In the second EQ type available (defined in the Configuration Tool), an
additional Notch filter can be defined. The controls for the Notch filter
show up in the filters section of the LACP menu system.
Filters Separate from the EQ Section there are two dedicated High-pass and Low-
pass filters associated with the input selector. The range of these filters are
continuously variable between 20 Hz and 20 kHz and include slope selec-
tions of 12, 18, or 24 dB/octave.
In addition, an analog high-pass filter with a corner frequency of 75 Hz
and a slope of 12 dB/octave is available in the D19m 24 bit Mic/Line Pre-
amplifier.
