1.0 INTRODUCTION
The DSX 2040 is a 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 EQ per channel, 31 bands of GEQ per input, 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 requirement. The DSX 2040
can be controlled or configured in real time on the front panel or with the intuitive PC GUI
accessed via the RS-232 or USB interface. Software upgrade for CPU and DSP via PC
keeps the device current with newly developed algorithms and functions once available.
Multiple setup storage and system security complete this professional package.

1. USB - a standard Type B USB connector. Device driver from the provided software
CD must be installed prior to usage.
2. RS232 - a standard female DB9 socket. A straight through cable is required for PC
connection.
3. Mute (Channel Menu) Buttons - Mute or un-mute input and output channels. When
an input channel is muted, a red LED will come on for indication.
When the <<Menu or Menu>> key is held down, the Mute Buttons selects the
corresponding channel for the LCD menu display and is acknowledged by a green
LED below the button. The last modified menu will be displayed on the LCD.
Multiple
channels can be linked or unlinked by pushing the desired channels. This
eases programming for same parameters across multiple channels. Multiple
Inputs can be linked together and multiple outputs can be linked together.
Inputs and Outputs are linked separately.
4. Channel Menu LED - Indicates the activated channels for data modification.
5. Peak Level LED - Indicates the current peak level of the Signal:
Signal, -12dB, -6dB, -3dB, Over/Limit. The Input Limit LED references to the
device's maximum headroom. The Output Limit LED references to the threshold of
the output limiter.
6. LCD - Shows all the necessary information to control the unit.
7. Menu Buttons - There are 6 menu keys: <<Menu (Menu Down), Menu>> (Menu Up),
<<Cursor (Cursor Down), Cursor>> (Cursor Up), Enter/Sys/Speed, Exit.
The functions of each key is explained below:
<<Menu: Go to previous menu screen. Holding this button down while
pressing Mute key will go to the specify channel menu.
Menu>>: Go to next menu screen. Holding this button down while
pressing Mute key will go to the specify channel menu.
<<Cursor: Go to previous cursor in the menu screen.
Cursor>>: Go to next cursor in the menu screen.
Enter/Sys/Speed: Enter is used only in the System Menu to proceed with selected
actions. Sys enters the System Menu from the main menu.
Speed modifies delay and frequency (1 Hz resolution mode)
data values by 100X.
Exit: Exit to the Main Menu.
8. Rotary Thumb Wheel - Changes parameter data values. The wheel has travel
velocity sensing which ease large incremental data modifications. For modifying
delay and frequency (1 Hz resolution), pressing the Speed key simultaneously will
increment/decrement the data value by 100X.
