3. Quick Start
This chapter is for those who cannot wait to use their new DCX2496 in a practical
application. You will find a description of how you can explore your DCX2496 and
its versatile and intuitive features below. This chapter is just a starting point for
future excursions. So, please read the entire user’s manual to take full advantage
of all your DCX2496’s features and functions.
Please work your way through the following six chapters (3.1 to 3.6), one after
the other. Here we go!
3.1 Selecting an output configuration
Press the MUTE button to enter the MUTE menu. Here you can mute the inputs
and outputs of the DCX2496. On this page you can mute or activate individual
channels by pressing the channel buttons (IN A/B/C and OUT 1-6), or all
inputs/outputs by pressing the PARAM and OK or CANCEL buttons. Thus, you can
monitor each frequency band, either individually or together with a neighboring
band, to allow perfect editing of the isolated frequency range. To quit the MUTE
menu press MUTE a second time. For more detailed information see chapter 4.6
“MUTE menu”.
3.4 Storing presets
Fig. 3.1: Setup In/Out
Press the SETUP button to call up the SETUP menu. On the first menu page,
select an output configuration (OUT CONFI­GURATION) to determine which
outputs are used for which frequency ranges. One mono and three stereo
configurations are available.
The mono configuration allows you to split the input signal into six different
frequency ranges. The stereo configurations allow a maximum of three different
frequency ranges per stereo side. The abbreviations L, M and H stand for Low,
Mid and High Speaker. For more information see chapter 4.2.1 “IN/OUT”.
3.2 Setting crossover frequencies
Fig.: 3.4: Store Internal/Card
Use the STORE button to save your presets. In this menu you can store either in
the internal memory (INT) or on a PC card (CARD). More information on the STORE
function can be found in chapter 4.8 “STORE menu”.
3.5 Recalling presets
Fig. 3.5: Recall Internal/Card
Press the RECALL button to load presets from the internal memory or a memory
card. Select either INT or CARD (PCMCIA memory card), then enter the preset you
wish to recall. We included some typical presets, which you can use as a basis for
your own applications. For further information see chapter 4.7 “RECALL menu”.
Fig. 3.2: Out X-Over Points
3.6 Restoring the factory presets
In order to assign dedicated frequency bands to the output channels, you have
to define the crossover frequencies (X-Over) for each of them. The crossover
frequencies determine the upper and lower limits of a frequency band,
which allows you to clearly separate the outputs from each other in terms
of frequency.
Press the corresponding OUT button (1-6) and select menu page 2/8 using the
PAGE buttons. With the parameters FREQ and TYPE you can define the slope
of the crossover frequency and also select a filter type. When the parameter
X-OVER ADJUST MODE is set to “LINK”, any changes to the crossover frequency will
also shift the neighboring frequency ranges. For more information see chapter
4.5.2 “X-OVER POINTS”.
3.3 Muting input/output channels (Mute)
If you wish to restore the ULTRADRIVE PRO’s factory presets, press and hold both
PAGE buttons on the front panel switching on the unit. The DCX2496 prompts you
to confirm (OK) or CANCEL. Press OK to erase the internal memory and restore the
factory presets.
Please note that restoring the factory presets will irrevocably erase all
edited presets.
4. Menu Structure and Editing
This chapter describes all functions, operating steps and parameter pages in full
detail. While working with your DCX2496, please keep the user’s manual on hand,
and use it as a reference in case of problems.
4.1 General operating structure and
display presentation
When you switch on your ULTRADRIVE PRO DCX2496, the display shows a graphic
with the current routing of the unit, i.e. how inputs and outputs are linked to
each other.

12 ULTRADRIVE PRO DCX2496 User Manual
Please use this mode on the first unit when several ULTRADRIVE PROs are linked
to each other via LINK A and B, and the first unit in the chain is connected to a
computer via the RS-232 interface. In this configuration, the last AND the first
unit in the chain must have their TERM switch ON, since both are integrated into
the system via only one LINK interface.
General rule: Whenever one device within a chain has been connected
to the system via only one LINK interface, its TERM switch must be
pressed (ON) to avoid data reflections and hence transmission errors.
In PC (RS-232) mode this switch is not needed because the LINK
interfaces are not used.
The parameter DELAY UNIT determines the units of both measurement and
temperature used for the delay settings in the corresponding menus. You can
choose between m / mm / C° and ft / in / F°. When you change from meters/
millimeters to feet/inch, the temperature will be changed automatically from
°Celsius to °Fahrenheit. These settings cannot be made independently of
each other.
The MUTE OUTS WHEN POWER ON function is used to protect connected
equipment such as power amps and loudspeakers. When it is on (YES),
all outputs of the ULTRADRIVE PRO are muted during power-up. To restore the
output configuration of your presets, you will have to activate the respective
outputs individually or call up the preset again using RECALL (see chapter
4.7). Using RECALL to switch from one preset to another automatically mutes
all outputs, as soon as a preset has a different output configuration.
However, if the output configurations are the same, the muted outputs of the
new preset will be loaded.
When MUTE OUTS WHEN POWER ON is disabled (NO), the last output
configuration used will be recalled during power-up.
4.3 IN A/B/C menu
On these pages you can define the EQ, delay and similar values for the individual
input signals, and hence optimize the overall sound.
4.3.1 GAIN
Press one of the buttons IN A, IN B or IN C to enter the INPUT menu of the
corresponding input. On the first page, you can adjust the input gain for the
signal (GAIN). The setting range is from -15 to +15 dB.
Fig. 4.31: In A Gain
Below this parameter you can see a graphic representation of the current IN-OUT
configuration (OUTPUT CONFIG). Additionally, the display shows whether or not
the input is used for the SUM signal (see chapter 4.4). This is just a message.
You cannot edit anything here! OUT configurations are shown on the
SETUP page 1/6. The input source selection for SUM and for the various OUTs is
determined on page 1 in the corresponding menus (SUM, OUT).
4.3.2 DELAY/NAME
Fig. 4.32: In A Delay/Name
You can delay either the IN A, B or C signal to compensate for arrival time
differences—resulting from offset stereo signals or so-called “delay lines”
(“delay towers”). Activate the function with DELAY (ON) and select the delay
time of your choice with DISTANCE/TIME. The values DISTANCE and TIME are
linked to each other, i.e. both values are edited simultaneously when you turn
the data wheel. IN A (B/C) NAME allows you to enter a name with a maximum of
8 characters for the input signal selected.
4.3.3 EQ
Fig.4 .33: In A EQ
On this page you can process the sound of the input signals with the help of
various equalizer settings.
The EQ parameter determines whether this function is generally ON or OFF. In the
adjacent NR field you can select the number of EQs. There are various filters
available, which can be used and edited. Their number depends on the current
processor capacity, which is shown as a percentage next to the number of the
filter. The free capacity of the processor is directly dependent upon the number
and type of the filter selected (e.g. >FREE: 33%).
Use TYPE to define the filter type you wish to use. You can choose from low-pass
(LP), high-pass (HP) and band-pass (BP) filters. Description:
The low-pass filter raises (positive gain) or lowers (negative gain) the level
of the frequency band below the adjusted frequency. The high-pass filter
raises (positive gain) or lowers (negative gain) the level of the frequency
band above the adjusted frequency. Use TYPE to set a slope of 6 or 12 dB/oct.
for the high-pass or low-pass filter, or to determine the quality (Q) of the
band-pass filter.
The band-pass filter raises or lowers the level of the frequency range around
the adjusted frequency. The quality parameter Q determines the width of the
resulting bell-shaped filter curve.
The FREQ parameter controls the cutoff frequency, at which the filter starts
working. In the case of the low-pass and high-pass filters, the cutoff frequency
is the point, at which low and/or high frequencies are processed. The entire
frequency spectrum ranges from 20 Hz to 20 kHz.
Use the GAIN parameter to define the degree of boost/cut applied to a specific
frequency band. The setting range is from -15 to +15 dB.
When you set GAIN to 0 dB, the corresponding filter is inoperative!
This means that you cannot select a new type. Only when this
values is higher or lower than 0 dB, will the filter be activated,
and you can select a new filter type. Please note that two or more
filters are used for one frequency range when LINK is active.
Consequently, the processor performance will decrease.
With the Q parameter you can set both the quality of the band-bass filter and
the amount of interaction with adjacent frequency ranges around the center
frequency. The higher this value, the lesser the influence on neighboring
frequencies. This function is available only for the band-pass filters; its range is
adjustible from 0.1 to 10.
The number of filters available depend on the processing power (>FREE)
available. Filters can be allocated to either the inputs or outputs in any
proportion. The more filters are activated, the lower the processing power and
vice versa.
