To test KEYED ICS operation of the AA82-060, be sure the VOX potentiometer is set fully clockwise and
all ICS audio is shut off. Keying the ICS switches should activate the specific microphone involved.
Note: Each microphone is individually gated in the AA82-060 and only the microphone involved with a
key signal is activated.
The front panel indicator should illuminate orange when there is activity on the intercom.
2.5.5 Music Selection (AA82-060 only)
The cover of the unit must be removed in order to access jumper locations. Reference Section 6 for
Exploded View AA82\060\904-0 and Component Locator AA82\060\924-0 drawings.
Note: The AA82 is a static sensitive device. Use proper ESD handling procedures when the cover is
removed.
To gain access to the jumpers, remove the cover from the AA82. Remove the top PCB by removing the
three pan head screws and carefully lifting it straight up. When reassembling the unit check that the pins
and connector are aligned properly before screwing the PCB down.
The two types of music inputs are configured by the position of jumpers JP101 and JP102, located on the
main PCB near the access hole for Q101. Music input type is determined as shown in Table 1:
Low Z/Portable cassette/CD compatible
