Introduction
Overview
SB 32.24 is a 5U, 40-input and 24-output Dante stagebox featuring 32 SuperAnalogue™ mic/line
inputs, 4 AES/EBU inputs, 16 analogue line outputs and 4 AES/EBU outputs. All analogue and AES
audio connectors are XLR-3 type.
SB 32.24 can be controlled remotely from SSL Live and System T consoles as well as from SSL’s
Network I/O Controller app for PC.
SB 32.24 is suitable for all high-quality AoIP applications of any scale. Redundant power, redundant
ruggedized etherCON Dante connection plus two user-specifiable SFP ports which provide network
extension or support a second independent Dante network complete the professional hardware
requirement.

MainsPowerConnections
Each Stagebox includes redundant PSUs with IEC connectors; either supply can individually power
the unit. Ideally these should be connected to separate power circuits to provide redundancy of
incoming AC power.
●PSU LEDs are informational and are green in normal operation.
●A flashing red PSU LED indicates the failure of PSU 1
●A static red PSU LED indicates a failure of PSU 2
ChannelLEDs
●Analogue signal LEDs (SIG) 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 – phantom power on
●Green flashing – channel Attention active
●Green & red flashing – phantom power on &
channel Attention active
Note: The three holes above each of the XLR sockets are part of the unit’s ventilation. Do
not block (e.g. with tape!)

HardwareConnections:
DANTEConnections
SB 32.24 has two redundant sets of network connections. The Network A ports feature etherCON
ruggedised RJ45 connectors, and the Network B ports are SFP cages, which can be fitted with either
RJ45, Single-mode or Multi-mode LC fibre connectors.
The SB 32.24 Network connections can be configured in two different modes:
In the first mode, the A and B networks are linked internally (A+B Network Link LEDs are 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.
In second mode, the A and B networks are discrete (A+B Network Link LEDs are OFF), and
isolated from each other. In this mode Network A transmits uncompensated audio (and receives
audio for the analogue and AES outputs and also control data) and Network B transmits the
compensated audio only. Note that they have to be synchronised to the same clock source.
Status&Reset(DHCP)
A+B Network Link LED indicates unit is configured to connect internal
A and B networks
Off: Networks not linked
Green: Network A and Network B Linked
Dante B SRC LED is reserved for future possibilities!
Reset DHCP independently resets the internal Networks to DHCP
supplied addresses. Insert a small ‘prodder’ into the relevant opening
and press and hold for approx. 3 seconds to reset to DHCP addressing. The LED on the chosen port
will briefly turn red to indicate this has happened.
FactoryReset
If BOTH Reset DHCP buttons are held for 6 seconds, this will trigger a Factory Reset of the
stagebox.
