3.14 SXL II - Control Interface
3.14.1 General Information
SXL II is the center piece for power management, amplifier control and monitoring. It works embedded in a
LAN network, over the internet, or as a stand-alone unit with front panel control.
Up to 16 amplifier channels may be connected to one SXL II. The 16 amplifier channels may be freely
combined of two-, four- and eight-channel amplifiers. The amplifiers are connected to the SXL II with the
I
2
C or RS–485 system bus.
The SXL II is not only used to control the amplifiers but to provide an unparalleled level of monitoring. The
control side of it will power up the amplifiers, control the volume, etc. The monitoring, however, will inform
about the current status of the amplifier or individual channels (e.g. temperature, etc.). In addition, the SXL
II provides full control of all features of the DSP incorporated into the XR-series.
Up to 16 complex scenarios (snapshots) may be recalled via the 8 logic inputs.
Its 8 output relays may be used for the signalization of errors or the control of external devices.
Two additional relays enable the control of external devices or scheduled applications like line monitoring,
etc.
The SXL II offers extensive protocols for various events: for uninterrupted control, all relevant events are
being stored and available over the Internet as Syslog and/or e-mail.
The internal signal generator allows for a scheduled, repetitive surveillance of the connected speaker lines.
