FXBus sends
Following the equalizers are the Insert FXBus sends. Each Input has two sends. Change the
destination of each send by placing the cursor on it and doing the usual thing with the Alpha
wheel and + and - keys. The FX Bus sends are stereo, and if an Input is stereo, both channels go
to the send.
Either send can be assigned to any of the four Insert FXBuses, or to ÒNoneÓ, with one exception:
the two sends on a particular Input cannot both be assigned to the same FXBus. So, for
example, if the Þrst send on Input B/L is assigned to FXBus2, the second send from Input B/L
cannot also be assigned to FXBus2. You can, however, assign as many
different Inputs to the
same FXBus as you likeÑincluding the left and right channels from a mono pair.
Each of the FXBus sends has a level parameter (ÒLvlÓ) that determines the gain of the signal
going to that send. Maximum level is 24.0 dB, and minimum is -79.0 dBÑthere is also an ÒOffÓ
position. 0.0 dB is unity gain.
Mono inputs (ÒMÓ)
If an Input is mono, then each of its FXBus sends has a Pan parameter. This determines how the
signal is distributed between the left and right channels going to the individual FXBus: -100% is
left channel only, 100% is right channel only, and 0% is both channels equally.
Stereo inputs with Pan (ÒSPÓ)
If the Input is set to ÒSPÓ, then each FXBus send has a Pan parameter and a Width parameter.
The Width parameter determines how much separation there will be between the left and right
input signals as they are sent to the FXBus: assuming Pan is set to 0%, a Width of 100% means
the signals will be completely separate, while 0% means they will be combined into Òdual
monoÓ. Negative numbers ßip the channels around, so that -100% means the channels are
separate, but with left and right reversed, while -50% means they are reversed and partially
blended.
The Pan control maintains the stereo image, but ÒtiltsÓ it one direction or the other. At 0% there
is no change to the signal, while at 100% both input signals are sent to the right channel. At
50%, what had been hard left at the input will now be in the center, and what had been in the
center at the input will now be halfway between center and right. Negative values tilt the signal
to the left.
Stereo inputs with Balance (ÒSBÓ)
If the Input is set to ÒSBÓ, then each FXBus send has a Balance parameter and a Width
parameter. The Width parameter, again, determines the separation between the two channels,
and when it is set to 0%, the signals are combined into Òdual monoÓ. Negative values ßip the
channels around.
The Balance control raises the gain of one input signal and lowers the gain of the other. So at a
setting of 100%, the right input signal will be louder (and totally in the right output), and the
left input signal will not be heard at all. At -100%, the left input signal will be louder and in the
left output, while the right input signal will be silent.
The Balance control follows the Width control, so if the Width is not 100% or -100%, some signal
from the opposite channel will ÒleakÓ into the Balance control, and thus that signal, at
corresponding low levels, will be heard in the outputs even at extreme settings of the Balance
control. If the Width is 0%, then the Balance control does the same thing that the Pan control
does in ÒSPÓ mode, when the Width is 0%: itÕs a mono panner.
