SYSTEM / Meters
Chromatic meters are displayed in the CONFIG screen, on Quick Channels and
there is one on the CQ-20B which can be set for use with any input or output
channel.
They use colour and brightness to express signal level in a smaller space and can
also show much lower levels than standard meters (from -72dB), so a source can
often be seen before being heard. They can be customised, either to show colours
that are easy for the user to distinguish between, or to show when particular signal
levels are reached.
Audio Level – Adjust the Audio Level for each Audio Signal State.
Colour – Assign a colour to each Audio Signal State.
Intensity – Select between a Fixed or Variable intensity.
Fixed = Meter switches instantly between states.
Variable 1 = Meter changes close to the endpoints of its range.
Variable 2 = Meter changes across its whole range
