1.0 Introduction
The XM-2040 is a complete 2 input - 4 output digital loudspeaker
management system designed for the touring or fixed sound installation
markets. The absolute latest in available technology is utilized with 40-bit
floating point processors and high performance 24-bit Analog Converters.
The high-bit DSP prevents noise and distortion induced by truncation errors
of the commonly used 24-bit fixed-point devices. A complete set of
parameters include I/O levels, delay, polarity, 8 bands of parametric EQ per
channel, multiple crossover selections and full function limiters. Precise
frequency control is achieved with its 1 Hz resolution. Inputs and outputs
can be routed in multiple configurations to meet any requirements. The XM-
2040 can be controlled or configured in real time with the intuitive PC GUI
accessed via the RS-232, USB or Ethernet (optional) interface. Software
upgrade for CPU and DSP via PC keeps the device current with newly
developed algorithms and functions once available.

7.0 Operating the Device
The XM-2040 is shipped with a special PC Graphic User Interface (GUI)
application - XConsole. XConsole gives the user an option to control the
XM-2040 unit from a remote PC via the serial communication link. The GUI
application makes it much easier to control and monitor the device,
allowing the user to get the whole picture on one screen. Programs can be
recalled and stored from/to PC’s hard drive, thus expanding the storage to
become virtually limitless.
