Behringer Ultragraph Digital DEQ1024 Owner's Manual

ULTRAGRAPH DIGITAL DEQ1024

(13) 

The 12-digit LEVEL METER shows the signal level of the input and output 

signals. Use the METER switch located below it to select the respective 

signal, whereby the output signal is indicated when the switch LED lights 

up (green), and the input signal is indicated when the switch LED is not lit. 

The red CLIP LED lights up as soon as the indicated signal is overdriven. 

The GATE and the LIMITER LED shows that the threshold of the respective 

dynamics processors is either exceeded or is below the selected value; 

the LED also indicates that the dynamics processor is active at this time  

(see (8)). Additionally, the volume of the pink noise generator and the 24-bit 

word length setting (see (12)) is shown on the LED METER.

(14) 

Keeping the STANDBY switch depressed for a few seconds puts the DEQ1024 

into standby mode (red switch LED lights up). In this case, the signal 

connected to the DEQ1024 is looped through without being processed.

All new settings are saved after approx. 2 seconds, so that powering 
the DEQ1024 off and then on again (by using the STANDBY or the POWER 
switch (20) on the rear panel) recalls the current settings.

(15) 

The balanced XLR and 1/4" TRS inputs are used for connecting an analog  

input signal.

(16) 

The analog output signal of the DEQ1024 can be taken by using these 

balanced XLR and 1/4" TRS connectors.

(17) 

The MAX. LEVEL switches increase the maximum signal level on the analog 

inputs and outputs from +12 dBu to +22 dBu.

(18) 

You can selectively connect an input signal in the AES/EBU format (via the 

XLR connector) or in the S/PDIF format (via the RCA connector) to the digital 

inputs. In PRE EQ and POST EQ modes, these connectors can also be used as 

insert returns (see (12)). Here, you can connect the output of your dynamics 

processor or similar equipment.

(19) 

The output signal is available on the digital output in the AES/EBU format 

(XLR connector) and in the S/PDIF format (RCA connector). In PRE EQ or 

POST EQ mode you can use these connectors as insert sends (see (11)). 

Connect the input of your external dynamics processor or similar 

equipment here. Unlike with the digital inputs, both digital outputs can be 

used simultaneously.

(20) 

The POWER switch powers up your ULTRAGRAPH DIGITAL. The POWER 

switch should always be in its “Off” position when you are about to connect 

the DEQ1024 to the mains.

(21) 

The mains connection is achieved via the standard IEC connector. A matching 

power cord is included. 

(22) 

You can exchange blown fuses that are located in the FUSES COMPARTMENT 

of your DEQ1024. Blown fuses must be replaced by fuses of the same type 

and rating. Please refer to chapter 5 “SPECIFICATIONS” for further details.

The flexible concept of the ULTRAGRAPH DIGITAL, with its wide-ranging 

possibilities for audio processing, opens up many application options. We will 

now present to you some of those possibilities with their typical settings.

This is surely the most common DEQ1024 application.
To achieve optimal results, you should keep in mind the following: 
Before you begin correcting the frequency response, running your audio program 

“unprocessed” first has proved itself useful. If distortion occurs, it should first be 

confronted within the P.A. system. The physical location of your loudspeakers 

also plays a huge role. No equalizer in the world can majorly improve the sound 

that was thoroughly wattered down by being bounced off the walls and ceilings. 

Modifying speaker positioning alone can create major improvements in the 

quality of your sound.
When using multi-way active speakers, you should also first correct the 

run-time and phase settings (the ULTRADRIVE PRO DCX2496 digital crossover 

from BEHRINGER gives you all the tools needed for this). Only then does the 

ULTRAGRAPH DIGITAL come into play. Background noise such as mains hum as 

well as extremely narrow-band resonance should first be eliminated by using 

the DEQ1024 (also see ch. 3.2.1). This should definitely be done before setting up 

the sound.
