EQ Types Options for PEQ, LO-SHF and HI-SHF
FREQ – EQ center frequency; the equalizer’s centered frequency can be set anywhere within the range
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. The equalizer’s bandwidth ranges from 0.02 to 2.50 octaves and can be set in 0.01
octave steps for PEQ (see EQ TYPE). The Q value is automatically displayed beneath the octave value. For
LO-SHF or HI-SHF, it is either 6 or 12dB/Octave.
LEVEL – EQ level gain. The EQ level can be set from -30.00dB to +15.00dB in 0.25dB steps.
EQ Types Options for AP-1 and AP-2
The all pass filters AP1, AP2 have two setting variables. One is a centre frequency, and the other is the
amount of phase shift at that frequency.
Use the all pass filter to compensate for driver phase mismatch where you do not want to select the
polarity reversal (180 degrees) across the entire frequency band, but only within a limited frequency band. For
example if the frequency chosen is 1000hz, and the phase chosen is 30 degrees, then from 300hz to 1000hz the
phase will change from 0 degrees to 30 degrees at 1000hz, changing back to 0 degrees at 3000hz.
FREQ – EQ center frequency; the equalizer’s center frequency can be set anywhere within the range 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.

Limiter parameters can be set by pressing the Cursor push-button to advance from THRESH to ATTACK
and finally to RELEASE. (Use the Cursor push-button to go backward from RELEASE to ATTACK then to
THRESH). Use the Data wheel to change the parameter’s settings.
THRESH – Limit Threshold. Ranges from -20 to +20dBu in 0.5dB steps.
ATTACK – Attack time. Ranges from 0.3 to 1ms in 0.1ms steps, then ranges from 1 to 1 00ms in 1 ms steps.
RELEASE – Release time. Can be set at 2X, 4X, 8X, 1 6X or 32X the attack time.
5. Source Menu
Use the Cursor push-buttons to select the Input channel for the current selected output channel. Use the Data wheel
to change the Source parameter settings. The parameters can be set in 0.25 increments from 0.00 to -40.00; the
Input can also be turned Off.
In1, In2, In3, In4 – The LCD displays the Input channel source for the current output channel. This
feature can be used to mix the input source or disable it (Off). If more than one input sources are enabled,
they will be summed together as the source for the current output channel.

6. Name
All output channels can be named to help identify the channel or function. The output channel Name can be set
by pressing the Cursor push-button to advance to the next character. (Use the Cursor push-button to go
backwards). The Data wheel changes the individual characters.
NAME – Channel name. 6 characters in length.
System Menus
The System menu allows system-level settings. This menu allows modifications to parameters that are related to
system behavior and general operation of the DLMS4080. The System menu can be accessed by pressing the
Enter/Sys key on the menu keypad (when no Input/Output or other System Menu is activated).
Note: All System Menus require the Enter/Sys key to be pressed for the selected
action to be activated.
1. Recall Menu – Program memory bank recall
The DLMS4080 has a built in non-volatile memory that can store up to 30 different program setups. A program
previously saved to memory can be recalled using this menu.
PROG – Program Number to be recalled. Use the Data Wheel to advance to the next program, press
Enter twice to confirm selection.
2. Store Menu – Program memory bank
The DLMS4080 has built-in non-volatile memory that can store up to 30 different program setups. The
current programs settings can be stored using this menu. The old program with the same program number
will be overwritten. Once the program is stored in the flash memory, it can be recalled at a later time, even
after powering down or power failure.
PROG – Program Number for the current data to be stored.
NAM – Program Name, allows a maximum length of 12 characters.

3. Config – Device Configuration
MODE – configures the mode of operation.
The DLMS4080 assigns the Input source for the corresponding outputs when the Mode of Conguration is
selected. The crossover point parameters like the filter type, cut-off frequency and slope have to be configured
manually in the Xover Menu in each Output menu.
Note: The configuration mode configures the input sources when selected.
The user can change the source afterwards if desired. It does not keep the
configuration in memory.
4. Copy – Copy channel parameters
With this menu you can copy parameters from one channel to another; all you need to do is select the source and
the target channel. Press Enter/Sys to nalize the copy.
Note: When the source and target channels are both inputs all audio parameters will
be copied (or if they are both outputs). When the source or the target are an input
while the other is an output, only the Level, Polarity, Delay and EQ are copied.
SOURCE – Use the data wheel to choose the channel to be copied, press the Enter/Sys.
TARGET – Use the data wheel to select the channel that the parameters will be applied to, press the
Enter/Sys push-button to copy the parameters.
