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.

5.0 Powering Up the Device
After powering up the unit, the following initialization screen is displayed
on the LCD:
This shows the software version
The initialization process takes about 8 seconds and during that period the
unit boots and displays the DSLP48 firmware version.
After the initialization process is finished the DSLP48 displays its main
screen:
The screen shows the current program number and program name
assigned to the unit. The program assigned is always the last program the
user recalled or stored before powering down the unit.
Now the DSLP48 is now ready to operate.

6.0 Unlocking the Device
The first thing you will need to do is to make sure your DSLP48 is unlocked.
If the unit is locked you can see all functions but cannot make any changes
via the front panel nor computer interface.
1: Press the Upper Left MENU key (on the control button on the right side
of the unit) and while holding down-press one of the output Mute buttons,
Release. This should bring up a screen with a Level control on it. Turn the
data wheel and see if this level changes. If it does your DSP is unlocked. If
it does not, follow the next steps.
2: If your unit is locked-proceed with the following. On the front of the
DSP locate the control buttons towards the right side. Press the HOME
button, then the ENTER button. This will get you back to the start screens.
Press the Upper Right MENU button repeatedly until you get to the OLD
PASSWORD screen. Then press one the same button one more time. This
will get you to the SYSTEM PASSWORD screen.
Now press ENTER- TWICE. This should unlock your DSP. Try step 1 above
to see if the unit is unlocked.
You will need to unlock the DSP in this manner whether you are using the
computer interface or front panel access.
See ALSO the section on Security/Passwords (page 15) for more
information.

7.0 Operating the Device
Tips:
Channel Linking - If the user presses the LEFT MENU KEYS and the MUTE
button of the Input or Output keys, holds it down and press any other
MUTE key(s) in the same group (Input or Output group), then the channels
are linked together. The green menu LEDs for the linked channels are lit.
Any modification of the data for the selected channel will be applied to the
linked channels as well. To cancel the linking, just press and hold the LEFT
Menu key and a channel.
7.1 Input menus
Each of DSLP48 input channels has a separate Menu key. There are 6 menus for
each input channel.
The MENU buttons select the different blocks of the signal chain. The CURSOR
buttons select the different parameters within that particular block. The DATA
WHEEL selects the particular adjustment needed.
Signal - Signal parameters
SIGNAL - Gain, -40.00dB to +15.00dB in 0.25dB steps.
POL - Polarity, can be normal (+) or inverted (-).
DELAY - Delay in 21us steps. Can be displayed in ms, ft or m. The time unit
of the delay can be changed in the System menu. The maximum delay
permitted is (90ms).
EQ - EQ parameters
EQ# - Selects one of the 8 available Equalizers.
LEVEL - EQ level gain. Ranges from -30.00dB to +15.00dB in 0.25dB steps.
DSLP48 User's manual - Page 10 of 27
(Input Menus continued)
FREQ - EQ center frequency. Ranges from 20 to 20,000Hz in either 1Hz
steps or 1/36 octave steps. The sampling rate and the frequency steps can
be selected in the System Menu.
BW - EQ Bandwidth. Ranges from 0.02 to 2.50 octaves in steps of 0.01
octave steps for PEQ. The Q value is automatically shown beneath the
octave value. For Lo-Slf or Hi-Shf, it is either 6 or 12dB/Oct.
I1: XXXXXX EQ
BW: 0.33 Q=4.36
Type - Type of EQ. The types can be parametric (PEQ), Lo-shelf (Lo-shf) and
Hi-shelf (Hi-shf), AP (All Pass).
GEQ
This is a standard 1/3rd octave graphic EQ on ISO centers (you cannot adjust
the freq), but only the boost/cut.
XOVER
This allows for both high and low CUT filters of L/R, Bessel or Butterworth
types and 6-48dB/oct slope rates.
COMP
This is a compressor that allows for THRESHOLD, ATTACK, RELEASE (as a
ratio of input time), RATIO,
Ch-Name - Channel Name
Name - Channel name. It is 6 characters in length.
Use the cursor keys and the data wheel to enter the name
