The talkback microphone level is factory adjusted to provide an output level of approximately 0dBu during typical speech
volume. The input gain of a comms system should be adjusted to match this level.
If adjustment of the console output level is necessary then presets for microphone gain and limiter threshold are available
on the rear of the master controls panel (the panel above the fader tile in the centre section).
Note that the compressor threshold may need to be increased – by turning preset VR1 clockwise – BEFORE attempting to
increase the amplifier gain, VR2.

The C100 HDS provides an inbuilt software oscillator. The oscillator signal can be assigned to any console output without
the need for external cabling.
Alternatively, external hardware oscillators (either analogue or digital, mono, stereo or 5.1) may be supplied. In this
configuration one or more circuits should be allocated on the appropriate analogue or digital input connector; these signals
can then be allocated as the oscillator inputs via the touchscreen.

The meter panel is fitted with 16 switches which are available for user defined functions.
The switches are linked to the console’s macro system so that each switch can be assigned to a range of internal console
functions. They can also be programmed to operate a relay closure on the RIO or GP IO boxes.
Note that the upper right macro switch will be used to initiate the core swap function on systems that feature redundant
processing.
The lower four positions are fitted with physically latching switches. This enables them to be used for internal switching
functions such as external TFT input switching.
Custom engraving for user option switches can be arranged – contact SSL’s Project Engineering Department for details.
