3.5.4 Digital Signal Processor (DSP)
The XR amplifiers are equipped with an internal DSP processor for extended functionality:
• Level Control
• Input routing of the two amplifier channels
• 10-Band Equalizer
• Dynamics (Limiter/Compressor/Gate)
• Delay
• Cross-Over
• Signal generator
• Up to 100 presets
The internal DSP can be controlled by:
• the Bittner Audio SXL II control interface
• the DSP software installed on a computer, connected via RS–485
3.5.5 Control by RS–485 and PC
The DSP can also be controlled via the RS–485 port on the rear panel of the amplifier. To establish control,
the appropriate software must be installed on a computer. The RS–485 interface was chosen to allow for
direct control from a computer or media controller without the use of an SXL control interface.
Although RS–485 offers many advantages, i.e. long distances, a data bus, it is not a standard interface on a
standard computer.
Caution
To allow for easy connection of a laptop to a RS–485 network, Bittner Audio offers the USB to
RS–485 converter NA–1.

In the RS–485 control mode the amplifier is identified by its address. Use the DIP SWITCH ADDRESS 1–6
settings to set the RS–485 node address from 01 to 64:
