2-14 Getting started
This panel is located in the console's center section. It is used for the as-
signment of masters, groups, auxiliaries, multitrack buses, and mix-minus
feeds.
Each channel features a Solo/PFL Switch. Depending upon the mode se-
lected within the center section, a variety of functions can be achieved, in-
cluding: Standard Solo, Solo-In-Place, Standard PFL, Broadcast PFL, etc.
A very handy PFL/Solo Reset is provided to disengage any solos regard-
less of where they are engaged on the console. This eliminates the need to
"search" for solos when using large console configurations. Solo safe and
interlock functions are also provided.
Equalizers Four fully parametric bands are provided on the D950. Each band, which
can be switched in and out independently, extends from 20 Hz to 20 kHz,
with a ±18 dB gain range. The EQ features a psycho-acoustically corrected
frequency response for high frequencies, similar to well-known analog EQ
designs. The two mid-bands can be switched between constant-Q and con-
stant-range modes. The high and low frequency bands can also be switched
to shelving mode. A second EQ type is available (defined in the Configu-
ration Tool), which features an additional Notch filter. The controls for the
Notch filter show up in the filters section of the LACP menu system.
Filters High-pass and low-pass filters are provided, with cutoff frequencies that
are variable between 20 Hz and 20 kHz, and slope selections of 12, 18, or
24 dB/octave.
In addition, an analog high-pass filter with a cutoff frequency of 75 Hz and
a slope of 12 dB/octave is available in the D19m 24 bit Mic/Line pream-
plifier.
Dynamics Two types of dynamics processing are available for the D950:
• Limiter/Compressor, which performs peak limiting and compression.
• Expander/Gate, which consists of an expander and gate processing block.
To avoid pumping and modulation, the dynamics processing sections fea-
ture high sampling rate transient detection. Distortion artifacts are minim-
ized through selectable, program-dependent attack and release times. The
D950's dynamics feature a side-chain input that can be used with or with-
out HP/LP filters. A unique "look forward" function is also featured. If de-
sired, this allows the entire transient portion of a waveform to be affected
when using the limiter/compressor or to be passed when the expander/gate
is used.
