1. Connect the user’s audio transmission source(s)
to the 250E/260E transmitter unit’s audio input
ports. Observe the proper polarity when connecting
your audio sources.
a. For balanced audio signal, connect the
positive (+), negative (-) and ground (G) of the
250E/260E unit’s terminal block to
corresponding terminals of user’s equipment.
b. For unbalanced audio signal, connect the
negative (-) and ground (G) of the 250E/260E
unit’s terminal block.
Connect the positive (+) terminal of the
250E/260E unit to the positive (+) terminal of
the user’s equipment and negative (-) or ground
(G) of the 250E/260E unit to the ground terminal
of the user’s equipment.
2. Lastly, connect the 250E/260E unit’s audio output
ports to the required audio receiver devices. You
are now ready to transmit and receive audio signals.
When connecting the audio sources, be sure to observe
the following for proper polarity.
Three position terminal blocks (feed-through) are
provided for the three-wire audio connection (see
Figure 2-4). We recommend you use 22 standard wire
(22-AWG) to connect the user’s audio equipment to
the 250E/260E unit. Use a flat head screwdriver to
tighten the terminal screw.
