SXL - Programmable Control Interface
3.7.1.
General Information
SXL 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. The 16 amplifier channels may be
freely combined of two-, four- and eight-channel amplifiers. The amplifiers are connected to the
SXL with the I²C system bus via a ribbon cable. As the ribbon cable length may not exceed 2 m, it
is recommended to keep the controlled amplifiers and the SXL in the same rack.
The SXL 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 provides full control of all features of the DSP incorporated
into the XR-series.
Up to 15 complex scenarios (snapshots) may be recalled via the four logic inputs. Its four output
relays may be used for the signalization of errors or the control of external devices.
Relay 4 may be used for time controlled applications, e.g. line monitoring, etc.
The SXL 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.
