SRC bypass – the Intelli-X
2
’s digital inputs are able to accept
input sample rates of between 32 and 192 kHz. Sample Rate
Converters (SRCs) are tted to each input to convert the sample
rate of the incoming audio to that of the internal processing.
The default is for the SRCs to be in circuit, but depending on
the synchronisation topology being employed, they may be
bypassed by ticking the checkbox.
Output settings
The screen shows the connectivity parameters for the selected
output channels. Use the rotary control to move the highlight up
and down the list.
Label A and B – this lets you change the name of the output
channels (from Output 1, etc.) to one of your choice, to suit the
application the in which the Intelli-X
2
is being used (e.g. Side
Hang 3 L).
Mode – as with the input connectors, set to Analog to derive
analogue signals from the output connectors and to AES3 for
use with a digital system. When AES3 is selected, the AES LED
[15] will illuminate.
Maximum analogue output level – this sets the maximum
signal level which can be applied to the outputs in the analogue
mode before internal clipping occurs. The maximum analogue
output level corresponds to 0 dBfs, and is indicated by the top
segment of the output bargraph meter. The default value is +21
dBu, but may be changed to +15, +18 or +24 dBu if preferred.
Consideration should be given to the headroom available in
subsequent equipment when setting this parameter.
Input Channels submenu
The Input Channels submenu allows adjustment of the various
parameters in each Input Channel signal chain. The submenu
offers ve menu items, Gain, Delay, Graphic EQ, Parametric
EQ and Compressor.
The various parameter screens show the settings for one Input
Channel at a time. The MUTE/SELECT buttons [13] under
the Input Channel meters are used to select which channel’s
settings is displayed.
Input channel submenu Softkeys – Copying and Ganging
Channels
From the Input Channel menu page, the following softkey
functions are available:
– opens an overlay with the following options:
– Copy Channel parameters. This feature lets you
copy all the parameters of the currently-selected input channel
to one or more other channels, reducing set-up time, and
removing the possibility of mis-matching channels. When Copy
Channel is selected, a further dialogue box opens asking for
the destination channel(s) to be identied.
The MUTE/SELECT button for the source channel ashes;
press the MUTE/SELECT button(s) for the destination
channel(s). Select Apply h. Alternatively, select Cancel (BACK/
HOME) to abort the operation.
– Gang/Ungang input channels. Input channels’
controls may be ganged together so that adjusting a parameter
in one channel also alters that parameter in those channels
that are ganged to it. This is obviously extremely useful with
stereo sources. The ganging operation also copies the source
channel’s parameters to the destination channel(s), but once
ganged, independent per-channel adjustment of parameter
values is no longer possible. A “chain” symbol appears at the
top right of the Input Channel screen of ganged channels.
Unganging channels is the same procedure; press Fn followed
by Gang/Ungang then deselect the channels to be unganged
by pressing their MUTE/SELECT buttons.
Gain
Two gain parameters are available for adjustment. Use the
rotary control to move the highlight to the parameter required.
Level – this sets the gain of the input stage for the selected
Input Channel (post the ADC in the case of analogue inputs).
The default gain setting is 0 dB, but can be set to any value
from -80 dB to +15 dB, in 0.1 dB increments.
Polarity – this allows phase inversion to be applied to the
selected Input Channel. The options are Normal and Inverted.
