ULTRACURVE PRO DEQ2496 User Manual

(9) 

The DEQ2496 has three 

DATA WHEELS

, which can be used to select and 

edit various parameters—again depending on the currently selected menu. 

Often, they perform a dual function, i.e. you can edit by turning and pressing 

a data wheel. Pressing the data wheels also changes the scaling of many 

parameters (step width) or confirms/resets previously made entries.

(10) 

With the menu keys you can select the individual menus of the various 

modules. They can also be used to select specific pages from these menus 

(like PAGE key). Each of these keys has a built-in LED, which lights up when 

the corresponding module starts modifying the sound. When the DEQ2496 

receives MIDI data, the LED of the UTILITY key lights up briefly. Keep this 

key pressed for about 1 s to bypass active modules or re-activate disabled 

ones. This function refers only to those modules which can be edited in 

the BYPASS menu (see chapter 3.7).

Use the 

POWER

 switch to put the DEQ2496 into operation. This switch 

should be set to “Off” before you connect the unit to the mains.

The 

FUSE HOLDER

 holds the mains fuse of the DEQ2496. Blown fuses 

must be replaced by fuses of the same type and rating. Please see the 

“Specifications” for further details. 

(13) 

The mains connection is made using the enclosed power cord and a standard 

IEC

 receptacle.

(14) 

The MIDI jacks enable the DEQ2496 to communicate with a computer or 

other MIDI equipment. Incoming MIDI data are received on the 

MIDI IN

, 

outgoing MIDI data are sent via the 

MIDI OUT

. Received MIDI data are 

also present at the 

MIDI THRU

 jack, so as to pass them on unmodified 

to other devices.

(15) 

Use the 

WORDCLOCK

 input to synchronize your DEQ2496 to external 

equipment via a wordclock signal. This connector is on a BNC coaxial jack.

Your DEQ2496 features a digital optical interface for the transmission/

reception of data in both AES/EBU and S/PDIF formats.

(17) 

The digital 

AES/EBU

 interface (XLR connectors) also sends/receives AES/EBU 

or S/PDIF signals.

(18) 

The 

AUX OUT 

phone jack is an additional stereo output, which allows you to 

tap the audio signal present at the digital outputs in analog form.

(19) 

The 

RTA/MIC IN

 XLR connector can be used to connect a measurement 

microphone providing an input signal for the real-time analyzer or SPL 

meter. This connector has a switchable +15 V phantom power supply for 

condenser microphones and can be set to microphone or line sensitivity 

(see chapter 3.11).

(20) 

The 

MAX

 switch raises the maximum level present at the MAIN inputs/

outputs from +12 dBu to +22 dBu.

These balanced XLR inputs are used to connect analog input signals.

3.  Menu Structure and Editing

This chapter provides you with detailed information on how too use the various 

functions on each menu page. We recommend that you keep this user’s manual 

available while working with the DEQ2496, so as to use it as a reference in case of 

any problems.

3.1  General operation and display structures

When you select a menu with the GEQ, PEQ, DYN, etc. keys, the display indicates 

the respective menu structure. To the left and right along the display you 

will find functions and parameters for preset editing, which are assigned to 

the A and B keys (left) and the three data wheels (right) and can be used for 

editing as required.
Most of the menus comprise several pages. The actual number of pages is shown 

in the top left part of the display, below the menu name. Use the corresponding 

menu key or the PAGE key to the left of the display to switch from one page to the 

next and back again.
As the functions performed by the A and B keys and the data wheels depend on 

the currently selected menu, all operating steps are described in full detail below. 

All menus are dealt with one after the other, and all functions and parameters are 

explained explicitly.

◊ 

Please note that the left and right channels will be edited 
simultaneously in STEREO LINK mode.

3.2  Equalizer modules

3.2.1  GEQ menu

Press the GEQ key to enter the GEQ menu. This menu has just one page and allows 

you to set all filters as desired.
