7 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. 3.

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.

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.

TRS inputs are used for connecting an analog
input signal.

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.
◊
Never connect a signal simultaneously to the AES/EBU and to the
S/PDIF input.
(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.
