Status LEDs
A series of LEDs towards the right hand side of the front panel indicate statuses as follows.
Channel LEDs
Status and Reset
The
AES IN ACT LEDs only
apply to the SB 32.24, they
are not required for the SB
16.12.
When running at
96 kHz the
SB 32.24 AES inputs must be
manually enab
led in place of
analogue inputs 25
- 32. This
is per pair of inputs.
The
AES IN ACT LEDs will be
green if the particular AES
ports have been activated
from the controller. Further
information is available in the
Operation at Different
Sample Rates
section of this
guide.
At
48 kHz all SB 32.24
analogue and AES inputs are
simultaneously available.

H/W LED
Green
- normal operation
Red
- indicates a fault has occurred, refer to the Setup
information window
NET A LED / NET B LED
Green
- Dante network connected (A or B respectively)
Red
(solid) - loss of primary network connection (A or B)
Red
(flashing) - loss of secondary network connection
(A or B)
PSU LED
Green
- normal operation, both power supplies active
Red
(solid) - primary PSU inactive
Red
(flashing) - secondary PSU inactive
SIG
analogue signal LEDs
are green above
-42 dBFS
and red at
-0.1 dBFS
(clipping)
48V/ATT indicates phantom power and/or attention depending on
red, green, or flashing combinations as follows:
Red (solid)
– phantom power on
Green (flashing)
– channel attention active
Green and red (flashing)
– phantom power on and channel attention
active
The three
holes above each of the
XLR sockets are part of the unit’s
ventilation.
Do not block (e.g. with tape!)
The A+B Network Link LED indicates the link
status of the internal A and B networks:
Off
- Networks not linked
Green
- Networks A and B linked
Configuration of the network link is detailed in the
Dante Controller section of this guide.
The Dante B SRC
LED indicates whether SRC is
enabled for the Dante B network.
Off
– SRC not enabled on Network B
Green
– SRC enabled on Network B
If either RESET A or RESET B are held for 6
seconds then the primary Dante network
connection of the chosen network will reset to
use D
HCP - once released the unit must be
rebooted.
If
RESET A and RESET B are held for 6 seconds
this will perform a device reset
- once released
the unit must be rebooted.

Device Reset
Performing a device reset will clear the SSL device settings. This includes ownership states and input
settings. This does not clear Dante Brooklyn card settings.
Brooklyn Reset
Resetting the Dante Brooklyn card to default settings is performed from Dante Controller. Under the
Device Config tab for a device select Clear Config. This clears the device name, channel labels, IP
address settings, sample rate, latency and existing audio routes. This does not clear SSL Ownership
settings.

Hardware Connections:
Mains Power Connections
Each stagebox includes redundant PSUs with IEC C14 inlets. Either supply can
individually power the unit. Ideally these should be connected to separate power
circuits to provide redundancy of incoming AC power.
Audio Inputs and Outputs
Electronically balanced mic/line inputs, line outputs, AES/EBU inputs and outputs on latching XLR-3
connectors.
See Appendix B for pinout information.
Dante Connections
The SB 32.24 and SB 16.12 have two sets of redundant network connections. These can be
configured in two different modes:
In the first mode, the A and B networks are linked internally (A+B Network Link LED is on). In this
mode both Network A and Network B are identical and output both the gain-dependant and gain-
compensated audio. Dante devices can subscribe to either one. Either set of network connections (or
both) can be used to connect to the stagebox, allowing Ethernet or fibre connectivity as desired.
In the second mode, the A and B networks are discrete (A+B Network Link LED is off) and isolated
from each other. In this mode Network A transmits uncompensated audio (and receives audio for
the analogue outputs, AES outputs and also control data) and Network B transmits the compensated
audio only. An SRC can be enabled on Network B if required. Further information can be found in the
Gain Compensation and Network B Sample Rate Converter (SRC) sections of this guide.
Configuration of the network link is detailed within the Dante Controller section of this guide.
A pair of LEDs per port provide
network information:
ACT
flashes when there is
network activity
GB/SFP
shows Ethernet/SFP
network status
Network A
ports feature etherCON
ruggedised RJ45 connectors
Network B ports are SFP cages which can be
fitted with either RJ45, single
-mode or multi-
mode LC fibre connectors

Dante Connection Examples
The following examples demonstrate common network configurations and the required setting for
the A+B Network Link, note this is not an exhaustive list. Only two consoles are shown for
simplicity, these examples would also apply for multiple console networks, or networks with
additional I/O devices sending/receiving signals directly to/from the SB 32.24 or SB 16.12.
Typically the master console will have control of the stagebox inputs. Additional consoles or I/O
devices can subscribe to either the uncompensated or gain-compensated splits depending on the
usage requirements and network link configuration. Further information can be found in the Gain
Compensation and Ownership sections of this guide.
Gain-Dependant Source and Gain-Compensated Splits Available to One Console
In this example with a single console, both
the gain-dependant and the gain-
compensated splits are available to the
console. Stagebox outputs are also available
to the console.
Gain-Dependant Source and Gain-Compensated Splits Available to Two Consoles
(No SFPs Fitted - External Switch Connected)
In this example, a FOH and monitor console
are both connected to the stagebox via an
external network switch. Both the gain-
dependant and the gain-compensated splits
are available to both consoles through the
Network A connections, no SFPs are required.
The Network B SFP connections could be used
instead if a direct fibre connection was
preferred.
Input ownership and stagebox outputs are
available to either console.
SRC can be enabled on Network B if required.
Further information can be found in the
Network B Sample Rate Converter (SRC)
section of this guide.
