Latching — The System 5 room relay can operate in two modes: latching or
momentary. In the latching mode, the relay remains active (latched) until it is
manually reset (unlatched).
Level — The relative intensity (strength, voltage, volume) of an audio or video
signal. The output level can be changed by attenuation (a decrease relative to
the input signal) or gain (an increase in the signal level).
RGB delay — This is used in Triple-Action (video mute) Switching. With triple-
action switching, the System 5 switches to the new sync signal before
switching RGB (video) signals. That allows the projector to adjust to (lock
onto) the new sync timing during a brief delay before displaying the new
picture, which will appear without glitches.
