Front Panel Interface
Figure 5-1 on page 10 shows that there are six Input Routers available on the LM 26. The signal from the first
four Input Routers can be routed to the Input Mixer for Module A & B, or directly to any output.
The first four input routers act as a switch, permitting one channel per router to be passed into the input
mixers or directly to any output. Similarly, routers 5+6 (pass-thru routers) provide input switching capability,
allowing any input to be routed to any output.
Each router has four priority levels allowing any input to be placed in a sequence providing automatic input
signal fail over. AES3 and Dante inputs have priority over analog inputs.
Only one analog input is allowed in each router, and
the analog input must be at the lowest priority level
in relation to any other inputs.
Two modes of input selection are available, Auto Select and Forced Selection. The selected setting is also
visible from the I/O STATUS screen on the front panel, and via the Lake Controller.
In Auto Select mode, Priority 1 is checked for a valid input signal; if no signal is found, Priority 2 is checked,
and so on until a valid signal is located; this process occurs if the currently selected input fails. In Forced
Selection mode, one of the four priorities is fixed regardless of whether a valid signal is present.
With a router selected on the front panel, press the middle button on the left of the LCD to activate this
parameter for editing; the text will be highlighted as shown in Figure 6-13. Use the illuminated rotary
encoder to scroll through the following options:
▸ Auto Select (default)
▸ Force Priority 1
▸
Force Priority 2
▸ Force Priority 3
▸ Force Priority 4
Assignment of Input Priority
Factory default settings assign AES3 to Priority 1 and Analog to Priority 4, with Priority 2 and 3 empty.
To change these settings via the front panel, select Priority slot number to be changed and use the rotary
encoder to scroll through the available options. Due to the signal hierarchy it is not possible to assign an
analog source to a higher priority than a digital source. Dante inputs are not selectable from the front panel
of the LM 26; their assignment must be made via the Lake Controller software.
