Fig. 3.6: The ULTRA-CURVE PRO as an ADC
You can select a sampling rate in the SETUP menu (if you will use your mixdown for CD production pur-
poses, select the 44.1 kHz sampling rate).
You can monitor the signal level in the LEVEL METER menu (Dig Max). Level changes should be made with
the master fader, with STEREOLINK switched on.
3.7 The ULTRA-CURVE PRO as a delay unit
In a large sound installation loudspeaker systems are often placed a considerable distance away from the
stage, or are suspended at a height (flown), in order to give those sections of the audience further away from
the stage the same clear, direct sound as those with better positions. In order to compensate for the time
differences existing between the main L and R loudspeakers and those further away, the signal to the latter will
be sent through an electronic delay device. This usually is a separate line-delay unit designated solely for this
purpose. The ULTRA-CURVE PRO removes the necessity of a separate delay unit, as it can produce a signal
DELAY for the material it is processing. This operates just as comfortably and effectively as having a dedicated
delay unit. The delay settings are be stored with the program. If several groups of identical loudspeakers are
being used, each having a different Delay time, they can be controlled by a multiple ULTRA-CURVE PRO
system, interconnected via the optional AES/EBU digital interfaces, thus avoiding any signal deterioration.
If we assume, for the purposes of this example, that the same type of loudspeakers are being used in the
various locations, under similar acoustic conditions (e.g. open air), then we can operate the system as follows:
The first ULTRA-CURVE PRO in the chain will be set up as in section 3.1, operating here as the signal source.
The second ULTRA-CURVE PRO provides the equalization for all successive loudspeakers, the EQ settings
can be used to compensate for the difference between the equalization of the stage L and R speakers and the
remote loudspeaker groups. The Delay setting corresponds to the time difference between the main L and R
loudspeakers and the first loudspeaker group.
The third ULTRA-CURVE PRO receives an equalized, delayed signal, therefore requiring only a further delay to
allow for the time difference between loudspeaker groups 1. and 2. Fine adjustments with the equalizer may, of
course, also be made.
