2 ADSP2 Speaker Connections

There are only two connections to make with your ADSP2 Speaker: 12VDC Power and Audio In.

2.1 12 VDC Power

A black wire and a red wire are provided without connectors for 12 VDC power. The red
wire should be connected to 12 VDC and the black wire to ground. The speaker unit should
operate well with voltages from 10-15 volts. The unit itself is protected against power
reversal, so there will be no harm if it is connected backwards inadvertently.

2.2 Connecting to your Speaker Output

ADSP2 Speaker connects directly to your Speaker or Headphones jack on your
transceiver. The audio connection is provided with a monaural mini-plug connector. If
your receiver uses another connection, you may either replace the existing connector
or use an adapter selected to fit your needs.

3 Speaker Operation

The ADSP2 Speaker operation is easy with a “One Touch” control for noise reduction and tone interference
rejection. When power is applied to the ADSP2 Speaker, the small red LED will light to let you know power
is on. On initial power up, the speaker is in bypass mode and the audio signal is connected directly to the
speaker. When the first level of noise reduction is enabled, one green LED will light. When the second
level of noise reduction is enabled, two green LEDs will light. There is no LED indication for the filter
level, which can be determined by sound.

4 Troubleshooting

At times, the LEDs may become out of sequence. When this or other problems occur, un-hook the power
and re-apply. This should re-set the speaker. For other questions, contact SGC technical support.
