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

). 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.
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

). Additionally, the volume of

the pink noise generator and the 24-bit word length setting

(see

) is shown on the LED METER.

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

on

the rear panel) recalls the current settings.
