B. Unpacking.
After unpacking the card, examine it carefully for possible damage that may have
occurred in transit. If equipment has been damaged, immediately file a claim with
the carrier stating the extent of damage. Carefully check all shipping labels and tags
for special instructions before removing or destroying them.
C. Installation.
The installation instructions shipped with the amplified speakers used with these
cards provide installation location and wiring instructions to complete the
installation.
To avoid electrical shock, do not attempt installation of cards when power is on.
Property damage, serious injury, or death could occur if independent audio conductors are
terminated together; both wires of the same polarity must be used as two
separate connections. NFPA 72 requires that the wires be terminated independently
The AM25CK and AM70CK connector cards are NOT polarity sensitive, but polarity
must be observed when placing speakers in close proximity to each other. See figure 2 for
wiring. The nominal impedance for both units is equal to,
1. Remove the amplified speaker's cover as described in the appropriate amplified
speaker instructions.
2. Plug the desired connector card into the socket in the amplified speaker.
3. Connect the white leads from the connector card to the audio inputs and outputs.
