16ULTRADRIVE PRO DCX2496 User Manual

The POLARITY parameter determines whether the phase of an output signal is INVERTED or not (NORMAL)—just as if you had inverted the polarity of your speakers. Use the PHASE parameter to adjust the precise phase position at the upper X-OVER frequency of the currently selected output. This fine adjustment is necessary when two output signals are not perfectly displayed by 0° or 180° with regard to each other.

4.5.5 DELAY

Fig. 4.42: Out 5 ➠ Delay

The DLY parameter in the top left corner of the display switches the DELAY function ON or OFF. With the LINK function you can couple several output DELAYS, so that you only have to adjust one DELAY for a whole stack of speakers. However, this applies to LONG DELAY values only. SHORT DELAY values can be adjusted separately and independently of the LINK function, and can be linked to each other in the SETUP menu (page 1/6), using the parameter

OUT STEREO LINK.

The parameters SHORT and LONG allow you to define the DELAY values of your choice. The setting range for the SHORT Delay is from 0 to 4,000 mm

(= 0.00 to 11.64 ms) and the LONG Delay can be adjusted from 0.00 to 200.00 m (= 0.00 to 582.24 ms).

With the LINK function activated, all LONG DELAY changes at one output are transferred to the corresponding output (L > M > H of one stereo side)— irrespective of the selected output configuration (e.g. LMHLMH).

◊If the LINK function is activated for one output, it will be switched on for ALL other outputs as well.

When you have set all DELAY values for the outputs and then activated the LINK function for one of them, the LONG DELAY values are NOT transferred to the linked outputs. This happens only when you edit any parameters that change the values of the linked outputs proportionally. The current DELAY values are still not copied, but rather the linked output values follow the changes.

The output links are shown graphically, with the currently selected OUT channel displayed as an inverted loudspeaker, in the top right-hand corner of the display. Below are the DELAY times shown on a timeline.

4.6 MUTE menu

Fig. 4.43: Mute ➠ Select

On this page, you can mute individual or all input/output channels.

Use the parameters MUTE ALL OUTS and MUTE ALL INS to disable (OK) or de-mute (CANCEL) the inputs/outputs of the DCX2496 in one go. To mute or de-mute individual channels, please use the respective input/output buttons (e.g. OUT 2, IN A, SUM, etc.). The lower part of the display only shows the status of the channel and does not allow for any selection.

MUTE settings of any type can be made exclusively on this page. As soon as an input/output has been muted, the bottom red LED above the corresponding input/output button lights up.

Press MUTE again or select another menu to quit the MUTE menu. Pressing the IN or OUT buttons has no effect.

4.7 RECALL menu

The increasing popularity of portable computer systems such as notebooks and laptop computers has prompted consumers to ask for portable and exchangeable storage media to give them a certain amount of flexibility. In the late 80’s a consortium of manufacturers developed a design, connection and software standard for memory cards called PCMCIA (Personal Computer Memory Card International Association). PCMCIA cards have also become the media of choice in audio engineering, allowing the user to store data externally via PCMCIA card slots. Today, the cards are usually referred to as PC cards.

Your ULTRADRIVE PRO DCX2496 has a PCMCIA card slot on the front panel, allowing you to store your presets easily, without having to use the internal memory of the device. Use the RECALL menu to recall previously stored presets (see chapter 4.8)—from the card or from the internal memory.

Fig. 4.44: Recall ➠ Internal/Card

In the upper display line, the parameter CURRENT NR indicates the current preset. If the preset has been edited but not yet stored, an arrow plus “EDITED” appears below this line. Now, if you try to load a new preset, the unit warns you that the current preset has not been saved yet. If you continue to load a new preset, all settings will be lost.

Fig. 4.45: Recall ➠ Internal/Card

If you wish to store the current preset before loading a new one, cancel RECALL and change to the STORE menu (see chapter 4.8).

The parameter RECALL NR allows you to select the BANK, from which to load a preset (INT or CARD) and the NUMBER of the preset. Both values are shown in the large right-hand window Use the data wheel to select a preset (1 - 60). Confirm your selection with OK to return to the previously selected menu (before entering RECALL).

◊“Empty” presets (without a name) cannot be RECALLED.

4.8STORE menu

Use this menu to store previously created presets in the internal memory or on a PCMCIA card.

◊Only use “5 V ATA Flash Card” PC cards. Though the memory capacity of the storage medium can be selected freely, it is impossible to store more than 60 presets. If you need more memory capacity you can store your presets externally on a PC (data dump via RS-232 or LINK RS-485 interface).
