Output Delay
Each Output Channel of the Intelli-X
2
may have up to 1.5 s of
delay inserted. This would normally be used for time aligning
the various speakers making up the system – for example,
individual speaker hangs with subs. Use the rotary control
to highlight the parameter required; ve are available for
adjustment:
Enable – either the ENABLE or Enter buttons may be pressed
to insert delay in the channel. Default is Off.
Duration – allows the delay to be set in units of time, from 0 to
1.5 s, in microsecond increments. Note that the duration is also
displayed as the equivalent number of digital samples.
Distance – this provides an alternative method of setting the
delay time, in units of distance, from 0 to 500 m. Entering a
delay in terms of distance will usually be more convenient in
real-world situations. Note that distance may also be entered
in feet, if preferred. (The internal distance-to-time conversion is
based on a nominal speed of sound of 346.5 m/s (1,137 ft/s),
at 20 °C and 50% RH)
Temperature – the speed of sound varies with temperature;
this parameter is used in conjunction with Distance. The
ambient temperature may be entered here to obtain a more
accurate delay value. The range available is -20 °C to +50 °C
and the default value is +21 °C. Note that the temperature may
be entered in °F if preferred, and that the value used applies to
all Output Channels.
Humidity – the speed of sound also varies with the relative
humidity (RH) of the air. If known, the RH may be entered here,
as a percentage from 0% to 100%, with a default value of 50%.
Note that the humidity value used applies to all delay settings
throughout the unit.
Output Channels submenu
The Output Channels submenu allows adjustment of the
various parameters in each Output Channel signal chain.
The submenu offers six menu items, Delay, Driver Alignment,
Crossover, Parametric EQ, Gain and Limiter.
The various parameter screens show the settings for one
Output Channel at a time. The MUTE/SELECT buttons [11]
under the Output Channel meters are used to select which
channel’s settings is displayed.
Output channel submenu softkeys – Copying and Ganging
Channels
From the Output 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 output
channel to one or more other channels. When Copy Channel
is selected, a further overlay opens asking for the destination
channel(s) to be identied. 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 output channels. Output 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
multichannel outputs. 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 Output 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.
