3. MENU STRUCTURE AND EDITING

Fig. 3.27: RTA menu (page 3)

If you wish to display the RTA in a larger format, please go to

page 3, where the illustration covers the whole display. All the

other functions available on page 2 can still be edited (RATE,

PEAK, etc.).

3.8.1 AUTO EQ function (AEQ)

The RTA menu (page 1) also includes an AUTO EQ function,

which allows you to analyze and correct the frequency response

automatically. This module is subdivided into three additional

pages. Please note that for the AEQ function to work you must

connect a measuring microphone to the RTA/MIC input (see

chapter 3.11).

Fig. 3.28: AEQ menu (page 1)

In terms of setup and functionality page 1 is identical to the

GEQ menu (see chapter 3.2.1). You can determine the desired

frequency response manually, onto which the automatic

frequency response correction of the input/output signals shall

be based. Once the curve of your choice has been set up,

please switch to the second page of the AEQ menu.

When you activate the AEQ menu, the current GEQ

settings will be taken over and used as the

desired frequency response curve.

Press the large data wheel to exclude individual frequency

bands from the AEQ mode. These bands will not be processed

by the automatic frequency response correction. It makes sense

to exclude the low-frequency range (up to approx. 100 Hz) from

AUTO EQing, because it is this range that may produce

inaccuracies during the calculation of the frequency response,

which might impair the results achieved with the AUTO EQ.

Fig. 3.29: AEQ menu (page 2)

On this page the signal to be processed is displayed as in the

RTA menu. The MAX. parameter lets you select an excerpt of

the entire level spectrum, depending on the actual magnitude of

the signal level (upper data wheel). The RANGE value is firmly

set to 30 dB. Press the upper data wheel to activate AUTO

mode, which automatically adjusts the displayed excerpt,

depending on the signal level. With the NOISE GAIN parameter

(-60 to -10) you can adjust the magnitude of the noise level.

AUTO EQ (lower data wheel) determines the speed at which

the EQs are analyzed and their settings are calculated. You can

select between the settings FAST, MID and SLOW.

The B key activates the room correction function (ROOM

CORR.), which cuts the high frequencies and boosts the low-

frequency range by tilting the desired response curve by

1 dB/oct.

When you press the A key (START AUTO EQ), the analyzer

starts measuring and calculating the AEQ settings. The

subsequent messages inform you that the unit analyzes the

level of the ambient noise at first, before it measures the noise

signal applied. Subsequently, the ULTRACURVE PRO corrects

the EQ values. Press STOP AUTO EQ to cancel this process.

Fig. 3.30: AEQ menu (page 3)

Page 3 of this menu shows the graphic EQ with the settings

adjusted on page 1. Here, too, you can START AUTO EQing and

change the NOISE GAIN parameter (large data wheel). However,

this page includes two additional parameters: DMAX adjusts the

maximum difference between two adjacent filters from 0 to

+15 dB (large data wheel), while MAX. SPAN (lower data wheel)

controls the maximum distance allowed between the desired

and real frequency response curve (0 to 30 dB). When this

value is exceeded, the corresponding range will not be

processed. Press the B key (DONE) to complete this process

and keep the adjusted curve. Press the RTA key to cancel.

Please note the AUTO EQ does not automatically terminate the

analyzing process.

After leaving the first page of the AEQ menu, there

is no way of returning to this page, but by leaving

the entire menu and recalling it again.

3.9 MEMORY menu

In the MEMORY menu you can save and recall complete

presets (page 1) or load and save individual modules (page 2).

Modules that are active within a preset are marked by a letter

(G = GEQ, P = PEQ, D = DEQ, W = WIDTH, Y = DYN). If the stored

I/O settings differ from the current ones, an I (=I/O) will appear

next to the letter indicating the module.

Fig. 3.31: MEMORY menu (page 1)

On the first page of this menu, you can save and recall complete

presets. To save a previously edited preset please use the large

data wheel to select a memory location from the table shown

(max. 64 user locations).

Preset #0 (INITIAL DATA) is a neutral default setting

which cannot be overwritten (READONLY).

You can either select an EMPTY memory location or overwrite

an existing preset, as long as it is not write-protected (PROTEC

ON). After selecting a memory location, press the A key to store

the preset (STORE PRESET).

When you try to overwrite an existing preset and

press the A key, the DEQ2496 will prompt you to

confirm your overwrite command (OVERWRITE

DATA?). Press the A key to CANCEL, or the B key

(or press the large data wheel) to confirm (OK).

After pressing STORE PRESET another menu will appear in

which you can name the preset (max. 16 characters). With the

data wheel (turn) and the upper data wheel (turn and press),

you can select the characters both horizontally and vertically.

Press the center data wheel to enter a character, subsequently

the cursor in the lower entry field will be moved to the next

position. Turn the lower data wheel to select individual positions

and press it to erase individual characters. When you keep the
