7.18 FADER

The fader is an ultra smooth 100 mm ALPS K-Series model controlling the

internal high quality VCA circuity.

There is no audio going through the faders which guarantees noise free

fading for ever! (see Chapter 6).

When the fader is closed, the signal is automatically muted, providing a

cut-off in excess of 100 dB. This high dB cut-off value ensures that the

main output is protected from crosstalk from announcers or fast spooling

tape decks.

The scale shows the attenuation. Normal operating position is at the ‘0’

mark, providing overall 0 dB of gain.

As described at the § 7.16, the START switch operates in tandem with the

fader position.

There are two methods of activating the channel:

a) when FADER ÙÙ START jumper is closed (see § 7.7 Module settings),

moving the fader away from the down position brings the module into the

ON (Start) status and a Start command is given (see Remote Interface).

Moving the fader back to its down position brings the module to OFF

status. This jumper does not affect START button operating.

b) when START ÙÙ FADER jumper is closed (see § 7.7 Module settings),

press START button to activate the module and provide a START

command. Press START again to de-activate the module. ON/OFF status

of the module is regardless of the fader position.

When the START button is not activated, the channel fader can be

opened without bringing the audio up and without generating a start

command. The channel can now be activated, by pressing the START

button (ON and START red LEDs will glow).

7.19 Detect LED

The Detect LED illuminates when a signal > - 30 dB is present on the

selected input (A or B). The control is performed PRE-FADER.
