2.2 SWITCHING ON THE UNIT
Press the toggle switch to the right to power on the SX-R4+ . A boot up screen is displayed for a couple of seconds,
followed by:
If the working day has changed while powering up the unit, the system
asks to confirm the date of the new working day. This allows keeping
the date of the current working days if the on going production works
is passing across midnight.
Press [OK] to confirm the new working day
Press [CANCEL] to keep the current working day
When one of the key is pressed, the unit will continue the booting
procedure; wait a few seconds until the main screen is displayed.
2.2.1 Switching Off the unit
Switching OFF the unit is controlled by the software, accessed via the [MAIN] menu then [POWER].

3. MAIN SCREEN DISPLAY
When the booting procedure is completed, the main screen displays the modulometers of the tracks, information's
related to the set up of the recorder and most of the recording parameters.
The modulometers are displayed "dynamically", showing only the assigned tracks whether armed or not. The overall
meter's range is 60 dBFS with a resolution of 0.5dB
Touching the screen within the modulometers area calls the [MAIN MENU]
Touching the centre of the blue area calls an overlay to quickly edit the metadatas.

4.1 INPUTS
The [INPUT] menu gives access to the configuration pages of the physical inputs of the recorder. Pressing a key calls
subsequent configuration and setting pages.
[XLR1 to XLR4] configure the physical XLR inputs of the recorder,
each XLR can independently be configured as Analogue, AES42 or
AES3. The icon reflects the actual settings
[AES 1-2] to [AES 3-4] configure the physical AES3 type digital input
of the 26 pin connector
[LINE 5-6] configure the physical TA3 Line Inputs 5 & 6 connectors
[AUX AES] configure the physical TA3 AES I/O connector
4.2 XLR SETUP
Pressing on a XLR icon calls the corresponding [XLR SETUP] page, showing the current configuration and settings.
When an [XLR SETUP] page is called, the headphones monitoring switches to SOLO mode so that the corresponding
input is heard in solo in the headphones; a bargraph displays the modulation level of the physical input (not the level of
the track on which the input is assigned.
4.2.1 XLR SETUP - Analogue
When an XLR is set as analogue for a Microphone or a Line input, that particular input is obviously a mono input and is
heard as such in the headphone. The modulation level is shown by a single bargraph.
LF CUT: toggles OFF, 60Hz, 120Hz Call a sub-menu to assign the input on a
track
Input Modulometer
Toggle the polarity of the input:
(phase normal or phase reversed)
Call a sub-menu to setup the type of the
XLR input, showing the actual status
Call a sub-menu to adjust the range of
the fader and how the range is stepped;
the actual fader level is displayed
Return to previous page
Call the Setup page of the Next or
Previous physical input
NOTE: - When the XLR is configured as Analogue input, the [LF CUT] key activates an analogue circuitry in the input
preamplifier. The [PHASE] and [LEVEL] are controlled by the DSP.
- The analogue inputs are protected by an internal RF Filter

4.2.2 XLR SETUP - Digital
A digital input, whether AES42 for a digital Microphone or as AES3 for a digital line, carries two channels; therefore the
[XLRx SETUP] show controls and modulation level for booth channels. The headphones monitors in stereo, the odd
channel on the Left and the even channel on the Right.
LF CUT: toggles OFF, 60Hz, 120Hz Call a sub-menu to assign the input on a
track
Input Modulometer of the Left channel
Toggle the polarity of the input:
(phase normal or phase reversed)
Call a sub-menu to adjust the range of
the fader and how the range is stepped;
the actual fader level is displayed
Input Modulometer of the Right channel
Return to previous page
Call a sub-menu to configure the input
type (Analogue AES42, AES3) , the
current type is displayed
4.2.3 XLR INPUT TYPE
Pressing the [STATUS xxx] key calls a new page to configure the input type of the XLR connector
Select the input type or turns the input
OFF to save on battery
Select Analogue for a Mic/Line input
Select AES3 for a digital line
Select AES42 for a digital microphone
When configured as analogue input, a
primary gain of 20dB and the 48V
Phantom can be activated.
This example shows that AES1-2 is
available for the 26 pin connector
Return to previous page Short cut the another XLR input
4.2.4 NOTES ABOUT THE AES RECEIVERS
The SX-R4+ recorder is equipped with 4x independent AES receivers, representing 8 audio input channels grouped per
pair (as per AES standard); each of them having its own ASRC (Asynchronous Sample Rates Converter) allowing
connection of non-synchronized digital sources.
These 4x AES receivers can be individually connected either on the 26 pin [AES IN] connector or on a XLR connector:
•AES receiver 1 can receive a feed from 26 pin AES 1-2 or from XRL1
•AES receiver 2 can receive a feed from 26 pin AES 3-4 or from XRL2
•AES receiver 3 can receive a feed from 26 pin AES 5-6 or from XRL3
•AES receiver 4 can receive a feed from 26 pin AES 7-8 or from XRL4
For example, if XLR x is configured as AES42 or AES3, the corresponding AES x on the 26 pin is no longer available.
