Limiter Indicators- The output indicators shows the status of the limiter and output level. The <SIG> indicator shows
signal presence and will illuminate when a signal is present in the output. The second indicator <-6dB> shows that the
signal has reached 6dB below the limiter threshold. The third <LIMIT> indicator signals that the threshold of that output
channel has been reached. The fourth <+6> indicates a signal 6dB higher than the limiter threshold. The <+6dB> indicator
also refers to the excursion limiter and will illuminate when the threshold of the excursion limiter has been reached. The
<˚C> indicator shows that the thermal limiter is active, which will protect against long term thermal stress. Please note
that because of the long release time of the thermal limiter, the <˚C> indicator may remain illuminated for several
seconds after signal on that channel is reduced. The <˚C> indicator illuminates when the limiter is in at least 1dB of limit.
Mute Buttons- DSP output mute status is indicated and controlled by illuminated buttons for each channel.
AES3 Active Indicators- The "AES3" active indicators show that the AES3 input/output is active for that pair of channels.
AES3 transmits two channels down one XLR cable. Channels 1 and 2 will be carried on connector 1; channels 3 and 4 will
be carried on connector 3 and so on.
Parameter Encoders- Three velocity sensitive parameter encoders are used to adjust parameters shown on the display.
Up to three parameters at a time are displayed on the screen. The parameter name is shown above the parameter value
in each of the three screen sections.
Selection Indicators- Each page that is visited when navigating will usually show either one, two or three parameters
labelled "A", "B" and "C", each of which can be edited by turning the Encoder associated with that parameter also
labelled "A", "B" and "C".
Status Indicators- The "OVERLAY" indicator shows when there are parameters active on a group layer, which the user
cannot access through the front panel of the device. The "NETAUDIO" indicator shows that a networked digital audio
card is installed and routed (Such as Dante™ or AVB™). The "ONLINE" indicator has three states: Off – the unit is offline
and not connected to a computer or network. Flashing- the unit is searching for an IP address; if the unit does not find
an IP address the unit will assign itself an IP address automatically and the indicator will stop flashing. On- the unit is
online and connected with software. IP settings can be viewed or changed within the <UTILITY> pages.
Graphical Display- When the device is switched on, it will show the default screen. This provides a useful overview of
channel allocation and Drive Module presets. The screen contrast can be changed by pressing the <UTILITY> button to
navigate to "Screen" and using encoder "A" will change the percentage; this can also optimise the viewing angle. In most
pages the currently selected channel and parameter information is displayed on the upper part of the screen and the
parameter value on the lower part of the screen.
Page Selection Buttons- When one of the buttons <INPUT>, <OUTPUT> or <UTILITY> is illuminated, the up <> and
down <> arrows will also illuminate, informing the user that these buttons may be used to scroll through the various
pages of parameters that may be viewed and edited. The <ENTER> button is used to confirm an operation such as storing
or recalling a preset or snapshot. It will illuminate when the user is being invited to press it. It will flash when pressing
this button will activate an important function.
Menu Buttons- There are three buttons to determine which section of the device to view or edit. The <OUTPUT> button
displays pages of parameters associated with a particular output channel. The <INPUT> button displays pages of
parameters associated with a particular input socket or input DSP channel. Pressing <INPUT> or <OUTPUT> buttons
repeatedly will scroll through the inputs/outputs of the processor. After the last channel, navigation returns to the
default screen. The <UTILITY> button displays pages of miscellaneous parameters not associated with any particular
channel. Whilst in Edit mode, one of these three buttons will be illuminated. They are mutually exclusive – pressing one
of the buttons will deselect any others that are active. Pressing Utils will escape back to the default screen.
Input Signal Indicators- A set of five indicators show "Sig", "-12", "0dBu", "+6" and "+12" for each of the DSP inputs "A"
"B" "C" "D". The signal present Indicators operate at approximately –40 dBu, giving a useful indication of even relatively
low input signal levels. The "0dBu" indicators are intended to show nominal operating level and can also be useful for
setting system gain structure.
Input Clip/mute Indicators - warn the user of input overload and operate at +19 dBu. The "CLIP" Indicator will only come
on when all other signal lights are illuminated. This indicator also shows a muted input state, and will remain illuminated
at all times whilst mute is active. Input mute is turned on/off in the <INPUT> gain page.
