The long-established leader in general aviation audio control has added to their extensive
list of products with the introduction of the PAC24. This audio control panel was designed
from the outset as an upgrade/replacement for the popular KMA24 –71, a product manufactured
by King Radio. The KMA24-71 was used extensively in dual audio panel installations for
high-performance and rotary-wing aircraft.
The PAC24 can easily replace these units, while adding utility and performance. The
many of enhancements include; a powerful headset audio amplifier, and high-performance
IntelliVox® intercom, dual audio capability in a single box, full duplex mode for wireless
operations, and expansion capability with stereo IFE input.
Pilots want clear crew intercommunications and simple operation. That is what IntelliVox®
is all about! We have had great success with the IntelliVox® in the loudest environments,
from open door helicopters to WWII bombers. The IntelliVox® loves noise! The IntelliVox®
makes conversation seamless for crew and passengers, and can responds to dynamic flight
Like the KMA24-71, the PAC24 can accommodate 5 transceivers. A monaural system, the
PAC24 can include a music input. SoftMute™ silences music during radio traffic, but allows
music other times.
Besides the powerful intercommunication functions, the PAC24 incorporates a split mode
that will allow a single audio panel to separate two pilots on different transceivers. The pilot
can transmit and receive in com 1, while the copilot position will have access to four other
radios. In a dual configuration, the PAC24 uses a digital interface that permits unprecedented
control of the radio and intercom configuration. When combined with IntelliPax™ expansion
system, the dual PAC24 can be a 14-place system.
The audio amplifier is capable of providing 120 milliwatts (mW) into general aviation
headphones. According to PS Engineering's founder and president, “We asked helicopter
pilots what they needed. They said they wanted more audio punch to get through the cockpit
noise. Since they will wear earplugs under their helmets, they need a clean audio signal
with lots of energy.
