The options available are as follows:

9.13.3.1 Input selection and sensitivity settings

This option is selected by pressing soft function buttons 2 or 3 (Router 1 or Router 2) from Menu è Input
Cfg for Modules A or B respectively or by pressing button 2 or 3 while in INPUT view.

Figure 9.13.3.1: Input selection
and sensitivity view
It can be seen from figure 8.1 (page 33) that each processing module – A and B – is fed with a signal which
is a mix of the two input signals selected by the two input routers. In the simplest configuration, the input
mixers will be set so that the signal selected by Router 1 feeds Module A only, and that selected by Router
2 feeds Module B only. However, this can be modified by adjustment of the Input Mixer levels via the Lake
Controller software. See the Dolby Lake Controller User Manual chapter 7.2.2 for further details.
Each Router is essentially a six-input switch, permitting one of six possible sources to be routed to either
Input Mixer. The six sources are:
▸ Analog input 1 (
▸
Analog input 2 (
▸ AES/EBU digital input Ch A (
▸ AES/EBU digital input Ch B (
▸ Dante network Ch A (
▸
Dante network Ch B (
A "seventh" routing selection is to have no input selected. ( Empty )
There are two possible signals for selection from the
AES/EBU digital input source, as the AES/EBU
bitstream carries two audio channels on a single
XLR connector.
The various inputs are assigned to one of four priority levels. The AES/EBU and Dante inputs have priority
over the analog inputs. This is because it is likely that in any situation where both digital and analog signals
are available, the digital signals will be the preferred input choice, with analog available as backup. Thus it is
not possible to select an analog input as the highest priority if digital sources are also defined at other prior-
ity levels. Also note that it is not possible to have both analog inputs in the priority list of the same router.
Two modes of input selection are available, Auto Select and Forced Selection.
