1.0 Introduction
The DSLP48 is a complete 4 input - 8 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, plus 1/3rd oct graphic EQ on the Inputs, multiple
crossover selections and full function compressors (Input) and limiters (Output).
Precise frequency control is achieved with its 1 Hz resolution.
Inputs and outputs can be routed in multiple configurations to meet any
requirements. The DSLP48 can be controlled or configured in real time on the
front panel or with the intuitive PC GUI accessed via the RS-232/USB or Ethernet
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.

10.0 PC Control Software
The DSLP48 is shipped with a special PC Graphic User Interface (GUI) application –
DSLP Control. This gives the user an option to control the DSLP48 unit from a
remote PC via the RS232/USB/Ethernet 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 hard drive, thus expanding the storage to become
virtually limitless.

COMPUTER SETUP
1: Once you have unlocked your DSP you can now connect to it via the computer.
Open the software and follow the prompts. If you are able to talk to the device
you will get a screen that looks like this:
2: If you have OFF LINE in device 1 Check the following things. Open the SETUP
window and go to Port connections. Make sure the ONLINE button is checked
under the Details window. If it was not, then check it and close the software and
reopen the software and try to connect.
3: If you still do not have a connection, it is probably because you are not using
the correct port number. Generally the Serial port is COM 1. If using a USB
connection, it could be just about any number. Open the COM Port pull down
window under Details in the SETUP-Port Connections window.
4: Scroll down and see if you have ports that have a blank beside the numbers.
Most will say “not available”. If you have several with a blank, you will need to go
to more detail to see which port is which. But if you only see one port that has a
blank name then double-click that number and it should be entered into the port
number. You will need to close and restart the software for this change to take
effect-instructions on the screen will say this also.
5: If you have several blanks then you will need to identify which port is which.
Do the following: Right click on MY COMPUTER-then MANAGE and then DEVICE
MANAGER.

DSLP48 User's manual - Page 20 of 27
(PC Control Software continued)
Scroll down until you see Ports Com and LPT. Open that up. You should see the
port number next to the particular device that is using it. In the case of USB it
should look like this
Note that number and then go back to step 4 above and enter that port number.
6: In a few weird cases you will need to make another change. Following the
steps in #5 above, go to the com port being used and double click it. Then open
the RESOURCES tab. In the middle there should be a box that says “Use
automatic settings”.It does not matter whether the box is checked or not;
change it, then hit CHANGE SETTINGS and close out the windows. It may take a
couple of seconds for this change to take effect.
NOTE: If you have to do step 6 with your computer, you will need to change it
every time you start your computer up and use the DSP.
You should be able to hook up to the device at this point and go ONLINE.
