HPF / LPF
These function blocks, each with one high pass
filter and one low pass filter, primarily serve as a
cross over network to split the signal between the
bass speakers (LOW) and the mid-high range
speakers (HIGH). Thus, the filters available here
ensure that the speakers only receive the signal
parts they are specialized to reproduce. There-
fore, the presetting of these filters should be
modified with caution!
It is possible to select from the list under
"Filter Type:" from various filter characteristics
(Butterworth, Bessel, Linkwitz-Riley) with differ-
ent slopes. The respective limit frequency is
adjusted under "Frequency". A low pass filter is
deactivated by setting its limit frequency to the
maximum ("Off" is shown under "Frequency").
A high pass filter is deactivated by setting its
limit frequency to the minimum ("Off" is shown
under "Frequency").
The pass-through characteristics of the filter
setting is shown in the frequency diagram.
LEVEL
The level for the input signal or for each of the
output signals HIGH and LOW can be adjusted
in these function blocks.
The phase can additionally be selected in
the function blocks of the two output branches:
Normal = output signal and input signal have
the same phase
Inverse = compared to the input signal, the
output signal is inverted
DELAY
This function block is available for both outputs.
Here a signal delay "Delay Time" can be
selected in milliseconds e. g. to readjust the dif-
ferences in delay time for different speaker dis-
tances. Below the input field for the delay the cal-
culated distance is shown in meters as well as in
feet and inches according to the delay time of the
sound.
A direct input of the distance with automatic
calculation of the delay time is also possible.
COMPRESSOR & LIMITER
For limiting the dynamic range the following pa -
rameters in this function block can be adjusted
to gether for both outputs:
Threshold = value from which the reduction of
the amplification starts
Ratio = the ratio by which the amplification is
reduced (e. g. the adjustment 9 : 1 means that
with a level increase by 9 dB, only an
increase of 1 dB will be admitted). With a high
compression ratio (20 : 1 or higher) and a
short response time ad justed (attack time =
1 ms or less), a limiting effect will be reached.
Release Time = time which has to pass after
dropping below a threshold value until the
amplification has regained its standard value.
Attack Time = the response time which
defines how quickly the unit responds to the
threshold value exceeded by reducing the
amplification

The Attack Time and the Release Time should
not be too short. In case the threshold value is
exceed ed for a longer period of time, quick, per-
manent readjusting will lead to audible distor-
tions.
6.6 Memorizing the adjustment in the
EEPROM of the signal processor
In order to make adjustments permanently avail-
able in the EEPROM of the signal processor:
1) Call the menu item "Program ± Save As Cur-
rent Program in Device".
2) Select the memory location "No. 1" up to "No.
6" and confirm. Thus, an adjustment memo-
rized here before is overwritten.
The adjustment is first memorized under the
name of the adjustment "Current Program
Name" last called and can then be renamed
( chapter 6.7).
This memorized adjustment is now also con-
sid ered as "Current Program", i. e. it is automati-
cally active when switching on the L-RAY system
the next time (start setting).
6.7 Renaming an adjustment in the
EEPROM of the signal processor
To rename the adjustment "Current Program"
called at present:
1) Call the menu item "Program ± Edit Current
Program Name".
2) Enter the new name and confirm.
The name is immediately modified in the mem-
ory location last selected in the EEPROM of the
signal processor.

6.8 Memorizing the adjustment in a file

To memorize the current adjustment in a file on
the PC (e. g. for later use or to use it for another
L-RAY system):
1) Call the menu item "File ± Save as ...".
2) Enter the file name and select the location of
the storage and confirm. The file name can
be selected independently of the name of the
adjustment.
The file name is automatically completed by the
extension ".asc". The name of the adjustment
selected at present is also memorized in the file.
For memorizing the adjustment with another
name in the file without modifying the name in
the EEPROM of the signal processor, proceed
as follows:
1) Separate the data connection to the L-RAY
system with the menu command "Communi-
cations ± Disable Communications".
2) Call the menu item "Program ± Edit Current
Program Name".
3) Enter the name to be memorized in the file
and confirm.
4) Call the menu item "File ± Save as ...".
5) Enter the file name and select the location of
the storage and confirm.

6.9 Loading an adjustment from a file

To load an adjustment from a file, no data con-
nection must exist.
1) If required, separate the data connection to
the L-RAY system with the menu command
"Communications ± Disable Communications".
2) Call the menu item "File ± Open".
3) Select the desired file and confirm.
4) The name of the adjustment can now be
viewed via the menu item "Program ± Edit
Current Program Name" and modified, if
required.
5) Call the menu item "Communications ± Enable
Communications". The program looks for
L-RAY systems connected.
6) If several L-RAY systems have been found,
select the desired system in the list "Select
Device:".
7) Under "Data Configuration" select the option
"Download Program Data To Device".
8) Click "Connect". The data connection to the
L-RAY system selected is set up and the
adjustments are transferred into the RAM of
the signal processor. The name of the adjust-
ment loaded from the file now appears
behind "Current Program Name:" in the upper
part of the main window. For permanent
storage of the adjustments in the EEPROM
of the signal processor call the menu item
"Program ± Save As Current Program in
Device" ( chapter 6.6).
6.10 Reset of the signal processor
to factory setting
Attention: This function cancels the memory
location selected at present in the EEPROM of
the signal processor irreversibly and overwrites
it with the factory setting.
1) A data connection must exist. If not, establish
it via the menu item "Communications ± Enable
Communications" (compare chapter 6.3).
2) Call the menu item "Program ± Load default
setting".
3) Confirm the safety request. The factory set-
tings are loaded from the file "factory
default.asc" written into the same directory
during installation as the program file.
The data are immediately transferred
to the L-RAY system and written into the
EEPROM of the signal processor under the
number selected at present.
6.11 Modifying the name of
an L-RAY system
To modify the name of an L-RAY system to
which a data connection exists at present:
1) Call the menu item "Device ± Edit Current
Device Information".
2) Enter a significant name (a maximum of
14 char acters from the ASCII set of charac-
ters) and, for controlling several systems via
the same data bus, a definite ID number
(1 – 10) for the system into the corresponding
field and confirm. The data are transferred to
the system and are displayed as "Current
Device Name" and "Current Device ID" in the
main window on the top right.
