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.
