ULTRAMIZER PRO DSP1424P
With television broadcasts varying volume levels can cause problems: Announcements, jingles, dialog and
background music can differ strongly in level. Here, too, the ULTRAMIZER PRO can level out these differences
in the program material and can thus provide a constant volume. Moderate use of the compressor, peak limiter,
super bass and exciter sections of the ULTRAMIZER PRO will help to achieve high and distortion-free nominal
volumes without loss of liveliness.
3.5.1 AM/TV broadcasting
AM broadcast has a clearly limited transmission bandwidth and relatively limited dynamics. The goal is to limit
the signal dynamics in such a way that the transmitted power is as constant as possible. The ULTRAMIZER PRO
permits the optimal use of the individual frequency bands continuously to optimize, in order to use the band-
width limited anyway and the signal-to-noise ratio permanently, close at the maximum. FM broadcast is more
sensitive to signal processing due to the larger bandwidth and dynamics. Most commercial transmitters want
to transmit with the highest obtainable average level and use a multiplicity of signal processors to achieve
this—despite the effects on the quality of the program material.
If a limiter with active pre-emphasis is used, the ULTRAMIZER PRO should be placed directly before it. That
way the transmitter’s subsequent limiter limits the signal less resulting in an improved overall sound. As
TV sound is usually also transferred in FM, the same goes for processing TV sound.
3.5.2 Telephone lines and wireless systems
The ULTRAMIZER PRO can dramatically improve the signal to noise ratio of telephone lines and wireless
systems while at the same time guarding subsequent devices against overload. They produce an even
modulation level and constantly keep the signal peaks under control. The studio can maximize the level
without the risk of overloading.
