ULTRACURVE PRO DEQ2496 User Manual
MIDI
When this parameter is ON, you can display all subsequent MIDI configuration
categories. When set to OFF, the DEQ2496 does not respond to any MIDI data.
MIDI CHANNEL
Here you can select the MIDI channel (1-16) on which the ULTRACURVE PRO
transmits and receives MIDI data.
CONTROL CHANGE
The exchange of CONTROL CHANGE data refers to the GEQ module only
(CONTROL CHANGE 1 - 31: left channel / CONTROL CHANGE 33 - 63: right channel).
PROGRAM CHANGE
PROGRAM CHANGE commands (both send and receive) are used to recall presets
#1 to 64 as well as the default setting (preset #0: INITIAL DATA).
SYSTEM EXCLUSIVE
Your DEQ2496 can both transmit and receive sys-ex data (system exclusive).
The transmission/reception of MIDI data can be enabled or disabled specifically
(ON/OFF). To be able to receive software updates, RECEIVE SYSTEM EXCLUSIVE
must be ON.
DUMP EDIT (A key)
This function allows you to transfer active settings via MIDI to another
ULTRACURVE PRO or a computer equipped with a MIDI interface.
DUMP ALL (B key)
The complete memory contents (all presets) of the ULTRACURVE PRO can be
transferred via MIDI to another ULTRACURVE PRO or a computer equipped with a
MIDI interface.
◊
Caution: the reception of the complete memory contents from
another unit will overwrite all existing settings! All saved presets will
be retained.

More information on MIDI can be found in chapter 5.1
"MIDI connections" and 7.1 "MIDI implementation".

3.6 I/O menu

On the first three pages of this menu you can determine the input/output
configuration, while the fourth page allows you to adjust the output signal delay
function, for example to make up for run-time differences, which occur when
several P.A. speaker stacks set up at a distance from each other are used.
Fig. 3.20: I/O menu (page 1)
On the first page you can select the DEQ2496's input source with the large data
wheel. You can choose between the analog MAIN INPUT, the digital inputs
(DIGITAL XLR or DIGITAL OPT) and the built-in PINK NOISE generator. Use the
NOISE GAIN parameter to adjust the volume level of the noise generator
(lower data wheel). The setting range is from -60 to 0 dB. The upper data wheel
controls the sample rate (CLOCK) used by the device. When the digital input has
been selected, the sample rate cannot be changed, because the DEQ2496 tracks
the sample rate contained in the input signal. When the PINK NOISE generator is
on, the modules DEQ and DYN (not LIMITER) are switched off.
Fig. 3.21: I/O menu (page 2)
On the second menu page you can determine the signal source for the AUX
output and the digital outputs. Selectable options are the unprocessed input
signal (MAIN IN or DIG. IN), the processed signal, post-graphic/parametric EQ
(BEHIND GEQ/PEQ), the processed signal post-EQ and post-dynamics module
(DYN), or the processed signal post-all modules, i.e. post-stereo imager
(BEHIND WIDTH).
Use the A key to select the consumer format (S/PDIF) or the professional
digital format (AES/EBU). The upper data wheel controls the resolution,
DITHER (OFF, 24-bit, 20-bit and 16-bit). The NOISE SHAPER function to be
activated with the B key reduces the dither-induced noise by moving it to a
frequency range where it is less audible.
◊
If the connected sample rate does not correspond to the rate adjusted
on the DEQ2496, this field shows the message UNLOCKED, which mutes
all outputs of the DEQ2496.
Fig. 3.22: I/O menu (page 3)
On the third page you can determine the input signal for the real-time analyzer.
Selectable options are MAIN IN (or DIG. IN), MAIN OUT, AUX OUT/DIG. OUT
(XLR and optical) and RTA/MIC input. When you select the RTA microphone
input, the A key switches the input sensitivity from MIC to LINE, and vice versa,
while the B key enables or disables the phantom power supply required for
condenser microphones (MIC +15 V), if the input sensitivity has been set to MIC.
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).
