Dear Customer:
Thank you for purchasing an AKG product. This manual contains important instructions for
setting up and operating your equipment. Please take a few minutes to read the instructions
below carefully before operating the equipment. Please keep the manual for future
reference. Have fun and impress your audience!
These headphones have been designed specifically for use with AKG HEARO Series digital
transmitters and feature an integrated diversity receiver.
The receiver converts the digital transmitter signal into an analog binaural signal. Digital
transmission ensures a degree of reliability that would be impossible to achieve with analog
technology.
Reflections of the transmitter signal off metal objects etc. may weaken or even cancel the
transmitter signal in some places (so-called "dead spots"). In many cases, all it takes to
restore clear reception is to move a few inches to one side. The receiver in the HEARO
DIGITAL uses two antennas integrated in the arches to receive the transmitter signal at two
different points in space. The diversity circuit will automatically activate the antenna that
delivers the better signal at any time. This system reduces the number of dead spots con-
siderably and dramatically improves reliability of reception.
