6.0 Control operations
6.1 Eq In
When the eq in switch is in the out, non illuminated position, all FCS 966
functions are bypassed and the input is connected directly to the output with
a high quality relay. This condition also occurs when the power is off, and
ensures that the signal is passed through the unit in the case of a power or
fuse failure. When the switch is pressed, the processed signal is present on the
output.
When in this EQ bypass mode, the input is still connected to all of the FCS 966
circuitry, so that all of the required facilities can be selected and set up prior
to operating the eq in switch and going ‘on-air’. Note that the output meter
monitors the input signal when the channel is in bypass mode.
6.2 Gain
This control allows the signal level at the output of the unit to be raised by up
to 10dB, or alternatively completely attenuated. Around the ‘zero’ position the
effect of the control is finer, allowing easy level matching of the equalized to
unequalized signals. More extreme settings allow the gain control to be used
as the main system level control. This is useful if there is more than one FCS
966 on the output of a signal source, each feeding a separate zone that require
different levels. An extra feature of the control is that it allows the signal to be
completely muted, again useful both during setting up and operation.
