5.1 Principles
On a traditional lighting console channels are controlled by linear
faders. In the case of the Navigator console channels are controlled
using Rotary Controls.
5.1.1 ChannelScrolling
Although the Navigator console has 96 channels it only has 12
Rotary Controls on the Preset. To allow all the channels to be
controlled a technique known as ‘scrolling’ is used: this can be
thought of as moving a small ‘window’ over a ‘picture’; only a
small part can be viewed at a time, but by moving the ‘window’
the whole ‘picture’ can be viewed, albeit piece-by-piece.
When controlling channels the scroll ‘window’ is the Rotary
Controls on the Preset, and the ‘picture’ is the 96 channels. The
position of the ‘window’ over the ‘picture’ is set by the Channel
Scroll, which is rotated clockwise or anti-clockwise to increment or
decrement the position. This determines the number of the channel
controlled by the left-hand Rotary Control Preset; the other Rotary
Control Presets control channels that are sequentially numbered
from this number.
The number of the channel controlled by the left-hand Rotary
Control is displayed on the top-line of the left-hand LCD panel:
Channel Block
When using Channel Scroll the ‘window’ position changes in units
that can be set from 1 to 12. This is referred to as the Channel Block.
