HIGH-PASS / LOW-PASS / BAND-PASS FILTERS

A low-pass filter: blocks unwanted high-frequency signals.

Example: you can use a LP-filter at 150Hz to filter the input of a subwoofer.

A high-pass filter: blocks unwanted low-frequency signals.

Example: you can use a HP-filter at 150Hz to filter the input of a mid/high cabinet.

A band-pass filter: you can combine a low-pass and high-pass filter to obtain a band-pass filter.

Example: you can use a BP-filter at 1,2kHz and 8,0kHz to filter the input of compression driver.

LIMITER AND COMPRESSOR - DIFFERENCES

The main difference between a limiter and compressor is the compression ratio. A limiter uses a ratio of 10:1

to 100:1 or even infinite, while a compressor will use a ratio of 10:1 or less.

A compressor reduces the dynamic range (louder parts made softer, softer parts made louder) so it reacts

as a sort of dynamic volume control. Therefore it's often used in radio studios.

A limiter "limits" the signal as soon as it reaches the threshold level. Therefore limiters are often used to

reduce peaks and protect your equipment (loudspeakers). The higher the compression ratio, the better the

protection.

HOW TO USE

Speaker management processors can tune your sound to perfection but in the hands of people with little or

no experience they can literally destroy the sound, and sometimes even the loudspeakers! So please

experiment and read a lot about their possibilities before you start using them, on the internet you can find a

lot of fine articles... Don't say we didn't warn you! 

TWO METHODS TO ADJUST THE SETTINGS

 PC-SOFTWARE: this is the easiest, fastest and most intuitive way, see further for more information.

 ON THE DLP-6: more time consuming, this method is explained below.

USING THE MENUS AND GENERAL SETUP

The complete menu structure is shown below: press the DIAL (4) to browse the different menu items, press

the NEXT/PREVIOUS buttons (5&6) to browse the submenus. Below you can find more information on each

item. Some terms are briefly explained in the previous chapter.

INPUT PARAMETERS – GAIN

Used to adjust the input gain of the DLP-6

processor.

 INPUT GAIN: turn the DIAL (4) to adjust

the input gain from -40dB to +12dB in

0,1dB steps.

 INPUT MUTE: press the button (10) to

activate,

press

the button

(9)

deactivate.

INPUT PARAMETERS – DELAY

The display shows the delays in meter,

milliseconds and foot. The DLP-6 can

introduce input delays up to 682,52ms or

235,07m!

 SMALL STEPS: turn the DIAL (4) to

adjust the delay in small 21µs steps.

 BIG STEPS: press the /buttons

(9&10) to adjust the delay in big 5,20ms

steps.

INPUT PARAMETERS – EQUALIZER

Both input channels have a 6band EQ,

each band can have different settings. Use

the /buttons (9&10) to jump between

the different parameter settings:

 ON/OFF: for each band you can choose

if it should be on or off, simply turn the DIAL (4) to select.

 EQ BAND: turn the DIAL (4) to choose the desired EQ-filter: you can choose 1 to 6.

 EQ TYPE: turn the DIAL (4) to choose the desired EQ-filter type:

 PEQ: Parametric equalizer, with the following parameters:

 LS1: Low-shelf 6dB, with the following parameters:

 LS2: Low-shelf 12dB, with the following parameters:

 HS1: High-shelf 6dB, with the following parameters:

 HS2: High-shelf 12dB, with the following parameters:

INPUT PARAMETERS – LINK SETTINGS

You can link the settings of input channels A and B so you only have to setup one input (A or B)  all

settings of the other input will be identical at all times. Turn the DIAL (4) to set the link ON or OFF and press

the SAVE-button (11). You will be asked if you are sure: press the /buttons (9&10) to choose OK or

CANCEL and press the SAVE button (11) again to confirm.

INPUT PARAMETERS – COPY SETTINGS

You can copy the settings between the input channels ("A to B" or "B to A"). This means that only the

ACTUAL SETTINGS are copied, there will be no constant synchronization between the channels! This is

what you can do:

 DON'T COPY: press the /buttons (9&10) to go to another parameter setting.

 COPY: press the SAVE button (11) to confirm copying  all settings will be copied between the inputs.

OUTPUT PARAMETERS – GAIN + PHASE + SOURCE

Used to adjust the gain and phase of the 6 outputs. For each output you can also select to which input it

should be linked. Use the /buttons (9&10) to jump between the different parameter settings:

 OUTPUT GAIN: turn the DIAL (4) to adjust the input gain from -40dB to +12dB in 0,1dB steps.

 PHASE: turn the DIAL (4) to choose "+" (output in phase) or "-" (output in anti-phase)

 SOURCE SELECT: turn the DIAL (4) to select the input that should be linked to the selected output:

 OFF: selected output is not used.

 A: selected output is linked to input A.

 B: selected output is linked to input B.

 A+B: selected output is linked to inputs A and B.

OUTPUT PARAMETERS – DELAY

The display shows the delays in meter, milliseconds and foot. You can choose delays up to 21,31ms or

7,34m!

 SMALL STEPS: turn the DIAL (4) to adjust the delay in small 21µs steps.

 BIG STEPS: press the /buttons (9&10) to adjust the delay in big 5,20ms steps.

OUTPUT PARAMETERS – EQUALIZER

All output channels have a 4band EQ, each band can have different settings. Use the /buttons (9&10) to

jump between the different parameter settings:

 ON/OFF: for each band you can choose if it should be on or off, simply turn the DIAL (4) to select.

 EQ BAND: turn the DIAL (4) to choose the desired EQ-filter: you can choose 1 to 4.

 EQ TYPE: turn the DIAL (4) to choose the desired EQ-filter type:

 PEQ: Parametric equalizer, with the following parameters:
