6 ULTRAGRAPH DIGITAL DEQ1024

(9) The DEQ1024 features a LOW CUT and HIGH CUT lter in its FILTER section,

allowing you to limit the entire frequency spectrum upward or downward.

TheHIGH CUT control is used to determine the cut-o frequency above which

the high frequency range is lowered (2.5 - 16 kHz). When turned all the

way to the right, the lter is deactivated (OFF). The LOW CUT control is used

to determine the cut-o frequency above which the low frequency range

is lowered (20 - 160 Hz). When turned all the way to the left, the lter is

deactivated (OFF).

(10) Use the GAIN control in the MASTER section to determine the output

volume of the ULTRAGRAPH DIGITAL in the range between -9 to +9 dB.

Inaddition, there is also a stereo imager function that lets you adjust the

stereo width and therefore the separation between the left and the right

stereo side. When the STEREO IMAGE control is turned all the way to the

right, you achieve the maximum widening of the stereo signal (WIDE);

whenthe control is turned all the way to the left, the stereo signal is

transformed into a mono signal (MONO). When the STEREO IMAGE control is

in its middle position, your signal is not processed (STEREO).

(11) When you keep the CONFIG switch depressed for a few seconds, youcan

select the operating mode of your DEQ1024: ANALOG (green LED),

DIGITAL(yellow LED), PRE EQ (yellow LED) or POST EQ (yellow LED). Whenin

the PRE EQ or POST EQ mode, you can use the rear panel digital connectors as

inserts, for example for an additional dynamics processor. When the unit is in

PRE EQ mode, the insert point is located pre EQ; when the unit is in POST EQ

mode, the insert point is located post EQ (see g. 2.5 and2.6).

(12) When you keep the CLOCK switch depressed for a few seconds, you can

select the desired sample rate with which your DEQ1024 is working: 44.1 kHz,

48 kHz or 96 kHz (green LEDs). To synchronise your DEQ1024 with the sample

rate of an external unit (e. g. through a digital mixing console), you have to

select the DIG IN setting (yellow LED lights up).

◊ If you select the DIG IN setting, although no signal is connected to

the digital input, the DEQ1024 is not able to synchronise with any

sample frequency (yellow DIG IN LED is blinking). In this case the

ULTRAGRAPH DIGITAL switches to the sample frequency last connected

to the digital input. If you connect a signal to the digital input while

operating in the unsynchronised mode, your DEQ1024 switches back to

normal mode and synchronises with the connected sample frequency

(yellow LED lights up).

To select the word length of the digital output signal (16 bit or 24 bit),

keep the CONFIG and CLOCK switches simultaneously pressed.

The 24-bit setting is shown by means of the -24 dB LEDs in the METER

display (see (13)). When the 16-bit setting is selected, no METER LED

lights up. This way, the DEQ1024 can be adjusted to the 16-bit inputs of

DAT and CD recorders or sound cards. The analog output signal is always

converted with 24 bit, independent of the above setting.
