‘he EX 4000 is an advanced professional power
A amplifier offering high power, comprehensive
jig Operational and protection features, and an ex-
tre mely flexible interface standard.
The output circuit combines high power with high
efficiency to provide greater average and dynamic
audio performance, while reducing normal sys-
tem cooling and AC requirements by greater than
90% over conventional designs. Á built-in limiter
prevents gross distortion during chipping to fur-
ther enhance dynamic performance. A sophisti-
cated thermal management system varies fan
speed with heat requirements and, in the event
of over-temperature, reduces gain until normal
operating temperatures return. Thermal muting
DCCUTS only In extreme cases.
The rear panel uses USC's Open Input Architec-
ture “which allows the use of second generation
signal processing and a wide variety of computer
control, optional input connectors, input trans-
formers, cinema crossovers, power limiters, pre-
cision attenuators, and other signal processing
cards as they become available
