ULTRACURVE PRO DEQ2496

3. MENU STRUCTURE AND EDITING

Fig. 3.23: I/O menu (page 4)

On the fourth page of the I/O menu, the ULTRACURVE PRO

DEQ2496 allows you to delay either the MAIN output signal or the

AUX signal, which is useful, for example, when the connected

speakers are positioned at a distance from each other, which

results in audible run-time differences and/or phase cancellation.

With the A key you can select the left or right stereo side.

Independently of the Stereo LINK mode both sides can be

processed separately. Keep the key pressed to edit both sides

simultaneously. The B key determined whether the MAIN or AUX

output signal is processed. Keep this key pressed to reset all

delay settings.

With the upper data wheel you can determine the unit for the

delay settings. You can choose between milliseconds (0 - 300

ms), feet (0 - 338.08 ft) or meters (0 - 103.08 m). If feet or meters

have been selected, the lower data wheel adjusts the current

ambient temperature in °Fahrenheit or °C, so as to ensure an

optimum delay response pattern (TEMP.). This is necessary

because the speed of sound largely depends on the ambient

temperature. For example, at 20 °C ambient temperature, the

speed of sound is 343.6 m/s. The higher the temperature, the

higher the speed of sound (plus 0.6 m/s per °C).

Depending on the channel selected, the large data wheel now

controls the left or right stereo side of the output signal (DELAY

LEFT and DELAY RIGHT) or even both at the same time. Press

the wheel to select a coarse or fine adjustment scale.

+ The AUX output allows you to send out both the

delayed and the undelayed signal. This way, you

can set up a delay line without any additional

equipment (see also chapter 4.4).

3.7 BYPASS menu

The BYPASS menu includes one page, on which you can

select various BYPASS parameters for making comparisons

between different sound settings.

Fig. 3.24: BYPASS menu

In DUAL MONO mode you can activate the relay bypass function

for the left (upper data wheel: BYPASS LEFT) or right stereo

side (lower data wheel: BYPASS RIGHT). This connects the

analog left or right input of the unit to the corresponding analog

output, so that the signals bypass the modules completely. In

STEREO LINK mode the upper and lower data wheels disable

the modules of both sides simultaneously, so that only the

unprocessed input signal can be heard (BYPASS ALL).

+ Keeping the BYPASS key pressed in DUAL MONO

or STEREO LINK mode activates the bypass relays

of both channels.

Turn the large data wheel to select individual modules, and

press it to remove them from the signal path. The same can be

achieved by pressing the B key (BYPASS MODULE). Keeping

this key pressed for a while will reset all BYPASS settings.

Keeping the module keys pressed for a while (GEQ, PEQ etc.)

will enable/disable the bypass function for individual modules.

+ Please note that the WIDTH function (stereo

imager) is not available in DUAL MONO mode, and

is therefore not displayed in the BYPASS menu.

3.8 RTA menu (Real-Time Analyzer)

Your ULTRACURVE PRO DEQ2496 features an FFT real-time

analyzer for the graphic representation of all frequency ranges

(61 bands). Additionally, this menu includes an AUTO EQ function

(AEQ) for automatic frequency response correction (see chapter

3.8.1).

Fig. 3.25: RTA menu (page 1)

On the first page, the A key selects the analyzer input signal.

These settings are the same you can adjust on page 3 of the I/O

menu. You can choose between the options MAIN IN or DIG IN

(L + R IN), MAIN OUT (L + R OUT), AUX. OUT/DIG. OUT (L + R

DIGOUT) and RTA IN (MIC/LINE). Use the A key for selection.

Keep the key pressed to determine which input signal is displayed

by the analyzer (left, right or complete input signalnot available

if RTA IN has been selected).

RTA MIC/LINE IN displays the signal present at the RTA/MIC

input (see chapter 3.11).

The MAX. parameter (upper data wheel) allows you to select

an excerpt of the entire level spectrum, depending on the actual

magnitude of the signal level. The adjusted dB value (0 to -60 dB)

refers to the upper limit that will be displayed. Press the wheel to

activate the AUTO function. Now the MAX value is adjusted

automatically, depending on the signal level. RANGE (lower data

wheel) determines the dynamic range displayed in four steps

(15, 30, 60 or 90 dB). Depending on the selected MAX value, the

dynamic range displayed will be extended towards the bottom

end.

LEVEL or PEAKH (large data wheel) allow you to select

specifically each of the 61 frequency bands and display their

current volume levels (LEVEL) or PEAK values referenced to the

adjusted frequency. The cursor arrows above and below the

graphic indicate the currently selected frequency range. The

level of the main signal is shown by the LEVEL meter to the left

of the RTA display.

Fig. 3.26: RTA menu (page 2)

On the second page of the RTA menu you can adjust the

release time in four steps (FAST, MID, SLOW and AVRG) with

the A key (RATE). If set to FAST, MID or SLOW, the RTA uses

peak detectors. If set to AVRG, it calculates average values

from the signal levels. In this mode, the analyzer seems to be

processing slower than usual. The B key (PEAK) selects in five

steps how fast the displayed signal peaks disappear again (FAST,

MID, SLOW, HOLD and OFF). If set to HOLD, the maximum values

of the individual frequency bands are frozen. If you press the

B key for about 1 s, the frozen level peaks are reset and can

be calculated anew.

+ If PEAK is set to HOLD, the name of the LEVEL

parameter changes to PEAKH.
