General Description
The DNA2404 series of amplifiers are an integral part of the IED
GLOBALCOM® Communications System, allowing a few audio zones to
be added where necessary when a full 16-zone T9160 amplifier frame is
not required. The amplifiers feature either CobraNet® or Dante™ digital
audio input and four channels of 600 watt amplification. The DNA2404
amplifiers are controlled with network commands for selecting
input routing and configuring EQ, output levels, ambient noise level
compensation, and sound masking (CobraNet® versions only). Amplifiers
are controlled through the GLOBALCOM® System Management Center.
The internal amplifier cards are Class D (switching mode) dual channel
600W amplifiers into the rated loads (70.7-Volts or 100-Volts).

Class D operation, combined with an integral switching mode power
supply, offers many advantages, and the unique IED design makes
full use of these benefits. They include higher efficiency, increased
reliability, improved performance, and lower operating cost. Switching
mode operation combined with high voltage power MOSFET devices
make it possible to eliminate the heavy, costly, bulky transformers. IED’s
design is stable under all load conditions (phase angles of 0 to 360
degrees). The amplifier card has 34dB of gain from its analog input to the
loudspeaker output. Attenuation is handled ahead of the power amplifier
by DSP controls through software.
Inputs are provided for connecting up to eight (8) 540S ambient noise
sensors (2 sensors for each output channel). This allows the output of
each channel to be automatically adjusted in real time based on the
measured ambient noise level in the zone.
The power amplifier has built-in voltage limiting to protect the
loudspeakers being driven. In addition, a temperature sensor on the
heatsink will annunciate a trouble condition if an amplifier becomes too
hot.
The DNA2404 series amplifiers feature LED indicators for power, audio
signals and fault status. A Form C relay is also included that will indicate
that a fault is present.
The DNA2404 amplifiers provide 600-watts per channel in either
70.7-volt or 100-volt transformer-distributed loudspeaker systems.
Models DNA2404CL and DNA2404CH utilize CobraNet
while models DNA2404DL and DNA2404DH utilize Dante™ for digital
audio transmissions. Models DNA2404CL and DNA2404DL operate from
a 120 VAC power source and the DNA2404CH and DNA2404DH models
operate from a 240 VAC power source.
Models DNA2404CL and DNA2404CH can be used in conjunction
with a GLOBALCOM
applications. The sound masking functionality can be enabled and
controlled on a per channel basis. Each of the four (4) output channels
has eighteen (18) bands of dedicated 1/3 octave filter sets. Sound
masking can be layered on top of background music (BGM) and / or
paging allowing for a complete paging, masking, BGM solution.
