thank you
Thank you for purchasing the AirLink, a stationary
line level audio transmission system. Whether the
need is to distribute audio to a distant location, to
an overflow crowd at a special event, or send the
announcer’s voice across the football stadium, AirLink can get the message across with ease. Tests
have been performed through multi-story buildings from basement to upper conference room,
from press box to a remote concession stand, and
to multiple locations using several receivers. Transmission distance in excess of 500 feet has been
achieved in direct line of sight with absolute clarity
and rock solid connectivity.
This manual contains helpful information and instructions for setting up and operating the AirLink
system. The system is comprised of a stationary
transmitter and remote receiver. You simply plug a
line level program signal into the transmitter and it
will transmit the program to the remote receiver.
TeachLogic appreciates your confidence with your
purchase of our AirLink system. Be assured that
TeachLogic products are built to very high quality
standards, incorporate state of the art technology,
and employ the most advanced manufacturing
methodology.

product description
The AirLink system is a wireless audio router that
transmits audio via an RF signal to a receiver. The
system is comprised of a transmitter base station
that transmits to a diversity receiver. The system
operates in the UHF range (640–664 MHz). The
system has 96 selectable preset channels. Transmitter RF output is 40 mW.
The input to the transmitter is line level audio. Two
line level audio signals can be input and mixed in
the transmitter for a composite signal transmission.
The output level of each input can be adjusted and
turned “on/off”. The output of the unbalanced line
input can be monitored with a headset.
The receiver is a diversity receiver, meaning the
signal will be received by either of two receivers;
whichever has the best reception. Each receiver
has a half-wave antenna for extra sensitive reception. The output of the receiver is either a balanced (XLR) or unbalanced (RCA) and is adjustable
from 0–700 mV.
