function buttons 2 and 3 select the Input Mutes for
Modules A and B respectively, and buttons 5 – 8 the
Module output mutes for the four output channels.
Once selected, the mute state can be changed with
the rotary encoder.
Note that the LEDs in the associated soft function
buttons (5–8) turn red when the Module output
mutes are applied from this menu page. On exiting
the menu system, it will be seen that they remain
red – indicating a MUTE condition – and the screen
blocks will display Mod. Out Mute .

It can be seen from figure 8.1 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 DLC PLM Edition software. See the DLC 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 1)
▸
Analog input 2 ( Analog 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 input has 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 priority 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.
In Auto Select mode, the control system inspects the
input set as Priority 1 for a valid input signal. If none
is found, it will proceed to the input set as Priority
2, and so on until a valid input signal is found. This
polling process will also take place if the current
selected input fails.
